Incarnation Reveals Glory of the Trinity by Blessed John Paul II

Incarnation Reveals Glory of the Trinity

1. "One source and one root, one form shines out in threefold splendour. From the bright depths of the Father bursts forth the power of the Son, the wisdom that created the whole world, the fruit born of the Father's heart! And there blazes the unifying light of the Holy Spirit". So sang Synesius of Cyrene in Hymn II at the beginning of the fifth century, celebrating the divine Trinity, one in source and threefold in glory, at the dawn of a new day. This truth of the one God in three equal and distinct Persons is not relegated to heaven; it cannot be regarded as a sort of "heavenly mathematical theorem" with no implications for human life, as the philosopher Kant supposed.

2. In fact, as we heard in the Evangelist Luke's account, the glory of the Trinity becomes present in time and space and finds its manifestation in Jesus, his Incarnation and his history. Luke interprets the conception of Christ precisely in the light of the Trinity: this is attested by the angel's words to Mary, spoken inside the modest home in the Galilean village of Nazareth, which archaeology has brought to light. The transcendent divine presence is revealed in Gabriel's announcement: the Lord God — through Mary and in the line of David's descendants — gives his Son to the world: "You will conceive in your womb and bear a son, and you shall call his name Jesus. He will be great, and will be called the Son of the Most High; and the Lord God will give to him the throne of his father David" (Lk 1: 31-32).

God manifested his love by sending the Son

3. Here the word "son" has a twofold sense, because the filial bond with the heavenly Father and with the earthly mother are closely united in Christ. But the Holy Spirit also shares in the Incarnation, and indeed it is his action which makes that conception unique and unrepeatable: "The Holy Spirit will come upon you, and the power of the Most High will overshadow you; therefore the child to be born will be called holy, the Son of God" (Lk 1: 35). The angel's words are like a short Creed which sheds light on the identity of Christ in relation to the other Persons of the Trinity. It is the Church's unanimous faith which Luke already places at the dawn of the saving fullness of time: Christ is the Son of the Most High God, the Great One, the Holy One, the King, the Eternal One, whose conception in the flesh takes place through the power of the Holy Spirit. Therefore, as John will say in his First Letter, "no one who denies the Son has the Father. He who confesses the Son has the Father also" (1 Jn 2: 23).

4. At the centre of our faith is the Incarnation, in which the glory of the Trinity and the Trinity's love for us is revealed: "And the Word became flesh and dwelt among us ... we have beheld his glory" (Jn 1: 14). "God so loved the world that he gave his only Son" (Jn 3: 16). "In this the love of God was made manifest among us, that God sent his only Son into the world, so that we might live through him" (1 Jn 4: 9). Through these words of the Johannine writings, we can understand how the revelation of the Trinity's glory in the Incarnation is not a flash of light dispelling the darkness for a moment, but a seed of divine life sown in the world and in human hearts for ever.

In this regard a statement by the Apostle Paul in his Letter to the Galatians is emblematic: "When the time had fully come, God sent forth his Son, born of woman, born under the law, to redeem those who were under the law, so that we might receive adoption as sons. And because you are sons, God has sent the Spirit of his Son into our hearts, crying, "Abba! Father!'. So through God you are no longer a slave but a son, and if a son then an heir" (Gal 4: 4-7; cf. Rom 8: 15-17). The Father, the Son and the Spirit are present and active, then, in the Incarnation in order to involve us in their life. "All men", the Second Vatican Council stressed, "are called to this union with Christ, who is the light of the world, from whom we go forth, through whom we live, and towards whom our whole life is directed" (Lumen gentium, n. 3). And, as St Cyprian stated, the community of God's children is "a people made one with the unity of the Father, the Son and the Holy Spirit" (De Dom Orat., 23).

Trinity is central mystery of Christian faith and life

5. "To know God and his Son is to accept the mystery of the loving communion of the Father, the Son and the Holy Spirit into one's own life, which even now is open to eternal life because it shares in the life of God. Eternal life is therefore that life of God himself and at the same time the life of the children of God. As they ponder this unexpected and inexpressible truth which comes to us from God in Christ, believers cannot fail to be filled with ever new wonder and unbounded gratitude" (Evangelium vitae, nn. 37-38).

In this wonder and acceptance we must adore the mystery of the Holy Trinity, which "is the central mystery of Christian faith and life. It is the mystery of God in himself. It is therefore the source of all the other mysteries of faith, the light that enlightens them" (Catechism of the Catholic Church, n. 234).

In the Incarnation we contemplate the Trinitarian love which is revealed in Jesus: a love that does not remain closed in a perfect circle of light and glory, but shines forth in human flesh and in human history; it pervades man, giving him new birth as a son in the Son. For this reason, as St Irenaeus said, the glory of God is the living man: "Gloria enim Dei vivens homo, vita autem hominis visio Dei". He is not so only because of his physical life, but especially because "man's life consists in the vision of God" (Adversus Haereses IV, 20, 7). And to see God is to be transfigured in him: "We shall be like him, for we shall see him as he is" (1 Jn 3: 2).

To the English-speaking pilgrims and visitors the Holy Father said:

I am happy to welcome to this audience the many school groups, as well as the parish and diocesan pilgrimages, especially from Denmark, Finland, Australia, the Philippines, Japan and the United States. As you pray at the tombs of the Apostles Peter and Paul, may you be strengthened in your faith and in your resolve to serve Christ in others. Upon you and your families I invoke the joy and peace of the risen Saviour.

Trinity Is Mysteriously Present in Creation by Blessed John Paul II

Trinity Is Mysteriously Present in Creation


1. "How greatly to be desired are all his works, and how sparkling they are to see!... He has made nothing incomplete.... Who can have enough of beholding his glory? Though we speak much we cannot reach the end, and the sum of our words is: "He is the all'. Where shall we find strength to praise him? He is greater than all his works..." (Sir 42:22, 24-25; 43:27-28). With these words full of wonder, Sirach, a biblical sage, contemplated the splendour of creation and sang God's praises. It is a tiny piece of the thread of contemplation and meditation which runs throughout Sacred Scripture, from the first lines of Genesis when creatures, summoned by the powerful Word of the Creator, spring from the silence of nothingness.

God's majesty is exalted above the heavens

"God said, "Let there be light'; and there was light" (Gn 1:3). In this part of the first account of creation the Word of God is already seen in action; John will say of him: "In the beginning was the Word ... the Word was God ... all things were made through him, and without him was not anything made that was made" (Jn 1:1-3). Paul will emphasize in the hymn in the Letter to the Colossians that "in him [Christ] all things were created, in heaven and on earth, visible and invisible, whether thrones or dominions or principalities or authorities — all things were created through him and for him. He is before all things, and in him all things hold together" (Col 1:16-17). But at the very first moment of creation the Spirit also seems to be foreshadowed: "the Spirit of God was moving over the face of the waters" (Gn 1:2). The glory of the Trinity — we can say with Christian tradition — is resplendent in creation.

2. We can see in the light of Revelation how the creative act is appropriated in the first place to the "Father of lights, with whom there is no variation or shadow due to change" (Jas 1:17). He shines resplendently over the whole horizon, as the Psalmist sings: "O Lord, our Lord, how glorious is your name over all the earth! You have exalted your majesty above the heavens" (Ps 8:2). God "has made the world firm, not to be moved" (Ps 96:10), and as he faces nothingness, symbolized by the chaotic waters which lift up their voice, the Creator arises, giving firmness and safety: "The floods have lifted up, O Lord, the floods have lifted up their voice, the floods lift up their roaring. Mightier than the thunders of many waters, mightier than the waves of the sea, the Lord on high is mighty" (Ps 93:3-4).

3. In Sacred Scripture creation is also often linked to the divine Word which breaks in and acts: "By the word of the Lord the heavens were made, and all their host by the breath of his mouth.... He spoke, and it came to be; he commanded, and it stood forth.... He sends forth his command to the earth; his word runs swiftly" (Ps 33:6, 9; 147:15). In the Wisdom literature of the Old Testament it is divine Wisdom personified that brings forth the universe, carrying out the plan God has in mind (cf. Prv 8:22-31). It has been said that in God's Word and Wisdom John and Paul saw the foretelling of the action of Christ "from whom are all things and for whom we exist" (1 Cor 8:6), because it is "through [Christ] also [that God] created the world" (Heb 1:2).

4. At other times Scripture stresses the role of God's Spirit in the act of creation: "When you send forth your Spirit, they are created; and you renew the face of the earth" (Ps 104:30). The same Spirit is symbolically described as the breath of God's mouth. He gives life and consciousness to man (cf. Gn 2:7), and brings him back to life in the resurrection, as the prophet Ezekiel announces in an evocative passage where the Spirit is at work breathing life into dry bones (cf. 37:1-14). This same breath subdues the waters of the sea at Israel's exodus from Egypt (cf. Ex 15:8, 10). Again the Spirit regenerates the human creature, as Jesus will say in his night-time conversation with Nicodemus: "Truly, truly, I say to you, unless one is born of water and the Spirit, he cannot enter the kingdom of God. That which is born of the flesh is flesh, and that which is born of the Spirit is spirit" (Jn 3:5-6).

God's invisible reality can be perceived in creation

5. So, in beholding the glory of the Trinity in creation, man must contemplate, sing and rediscover wonder. In contemporary society people become indifferent "not for lack of wonders, but for lack of wonder" (G. K. Chesterton). For the believer, to contemplate creation is also to hear a message, to listen to a paradoxical and silent voice, as the "Psalm of the sun" suggests: "The heavens are telling the glory of God; and the firmament proclaims his handiwork. Day to day pours forth speech, and night to night declares knowledge. There is no speech, nor are there words; their voice is not heard; yet their voice goes out through all the earth, and their words to the end of the world" (Ps 19:1-5).

Nature thus becomes a gospel which speaks to us of God: "from the greatness and beauty of created things comes a corresponding perception of their Creator" (Wis 13:5). Paul teaches us that "ever since the creation of the world his [God's] invisible nature, namely, his eternal power and deity, has been clearly perceived in the things that have been made" (Rom 1:20). But this capacity for contemplation and knowledge, this discovery of a transcendent presence in created things must lead us also to rediscover our kinship with the earth, to which we have been linked since our own creation (cf. Gn 2:7). This is precisely the goal which the Old Testament wished for the Hebrew Jubilee, when the land was at rest and man ate what the fields spontaneously gave him (cf. Lv 25:11-12). If nature is not violated and degraded, it once again becomes man's sister.

To the English-speaking pilgrims and visitors, the Holy Father said:

I extend a warm welcome to all the English-speaking pilgrims and visitors, in particular to the group from St Denis Parish in Hanover, New Hampshire, and to the Chapman University Choir from Orange, California. I wish to assure the pilgrims from Seton Hall University that I have prayed for the dead and the injured in last week's tragic fire at the university. Upon you all I invoke the grace and peace of our Lord Jesus Christ.

The Trinity: Fountain of Love and Light by Blessed John Paul II

The next three posts come from a series of General Audience Addresses given by Blessed John Paul II on the Holy Trinity. The talks extended from January 19, 2000 through September 20, 2000.

The Trinity: Fountain of Love and Light


Dear Brothers and Sisters,

1. "O superessential Trinity, infinitely divine and good, guardian of the divine wisdom of Christians, lead us beyond all light and everything unknown to the highest summit of the mystical Scriptures, where the simple, absolute and imperishable mysteries of theology are revealed in the luminous darkness of silence". With this prayer of Dionysius the Areopagite, an Eastern theologian (Theologia mystica, I, 1), we begin a difficult but fascinating journey of contemplating the mystery of God. After having reflected in the past few years on each of the three divine persons — the Son, the Spirit and the Father — in this Jubilee Year we intend to take a comprehensive look at the glory common to the Three who are one God "not in the unity of a single person but in the Trinity of one substance" (Preface for the Solemnity of the Holy Trinity). This choice corresponds to what was suggested in the Apostolic Letter Tertio millennio adveniente, which said that during the celebration phase of the Great Jubilee the aim would be "to give glory to the Trinity, from whom everything in the world and in history comes and to whom everything returns" (n. 55).

2. Taking our inspiration from an image offered by the Book of Revelation (cf. 22: 1), we could compare this journey to a pilgrimage along the banks of God's river, that is, of his presence and revelation in human history.

As a brief sketch of this journey, today we will dwell on the two extremities of that river: its source and its mouth, joining them in a single horizon. The divine Trinity, in fact, is at the very origins of existence and history and is present in their final goal. It constitutes the beginning and the end of salvation history. Between the two extremities, the garden of Eden (cf. Gn 2) and the tree of life in the heavenly Jerusalem (cf. Rv 22), flows a long history marked by darkness and light, by sin and grace. Sin has separated us from the splendour of God's paradise; redemption brings us back to the glory of a new heaven and a new earth, where "death shall be no more, neither shall there be mourning nor crying nor pain any more" (ibid., 21: 4).

3. An initial view of this horizon is offered by the first page of Sacred Scripture, which indicates the moment when God's creative power makes the world out of nothing: "In the beginning God created the heavens and the earth" (Gn 1: 1). This view is deepened in the New Testament, going back to the very heart of the divine life, when John proclaims at the beginning of his Gospel: "In the beginning was the Word, and the Word was with God, and the Word was God" (Jn 1: 1). Before creation and as its foundation, revelation has us contemplate the mystery of the one God in the trinity of persons: the Father and his Word united in the Spirit.

The biblical author who wrote the creation text could not have suspected the depths of this mystery. Even less could mere philosophical reflection have attained it, since the Trinity is beyond the capacities of our understanding and can only be known through revelation.

Nevertheless, this mystery which infinitely transcends us is also the reality closest to us, because it is the very source of our being. For in God we "live and move and have our being" (Acts 17: 28), and what St Augustine says of God must be applied to all three divine persons: he is "intimior intimo meo" (Conf., 3, 6, 11). In the depths of our being, where not even our gaze can penetrate, the Father, Son and Holy Spirit, one God in three persons, are present through grace. Far from being a dry intellectual truth, the mystery of the Trinity is the life that dwells in us and sustains us.

4. Our reflection in this Jubilee Year will take its themes from this Trinitarian life, which precedes and grounds creation. The mystery of the origins from which all things flow, God appears to us as the One who is the fullness of being and communicates being, as the light that "enlightens every man" (cf. Jn 1: 9), as the Living One and giver of life. He appears to us above all as Love, according to the beautiful definition in the First Letter of John (cf. 1 Jn 4: 8). He is love in his inner life, where the Trinitarian dynamism is the very expression of the eternal love with which the Father begets the Son and both give themselves to each other in the Holy Spirit. He is love in his relationship to the world, since the free decision to make it out of nothing is the fruit of this infinite love which radiates into the sphere of creation. If the eyes of our heart, enlightened by revelation, become pure and penetrating enough, they can by faith encounter this mystery in which everything that exists has its root and foundation.



5. But as we mentioned at the beginning, the mystery of the Trinity also lies before us as the goal to which history is directed, as the homeland for which we long. Our reflection on the Trinity, in the various realms of creation and history, will look at this goal, which the Book of Revelation very powerfully points to as the seal of history.

This is the second and final part of God's river, which we referred to a few moments ago. In the heavenly Jerusalem the beginning and the end reconverge. For God the Father, who sits on the throne, appears and says: "Behold, I make all things new" (Rv 21: 5). At his side is the Lamb, i.e., Christ, on his throne, with his light, with the book of life containing the names of the redeemed (cf. ibid., 21: 23, 27; 22: 1, 3). And see: at the end, in a gentle and intense dialogue, the Spirit who prays in us and with the Church, the Bride of the Lamb, says: "Come, Lord Jesus" (cf. ibid., 22: 17, 20).

At the end of this first sketch of our long pilgrimage into the mystery of God, let us return then to the prayer of Dionysius the Areopagite, who reminds us of the need for contemplation: "It is really in silence that we learn the secrets of this darkness ... which shines with dazzling light.... While remaining completely intangible and invisible, it fills minds that know how to close their eyes with the most beautiful splendours" (Theologia mystica, I, 1).

To the English-speaking pilgrims and visitors the Holy Father said:

I warmly welcome the group of Bishops from the United States taking part in a seminar at the Pontifical North American College. I extend a special greeting to the students from Horsens, Denmark, from Loyola University of Chicago, and from the Augustinian High School in Tulsa, Oklahoma. Upon all the English-speaking pilgrims and visitors I invoke the abundant blessings of Almighty God.

Excerpt from THE CATHECHISM OF THE CATHOLIC CHURCH - Part 1, Section 2, Chapter 1, Article 1, Paragraph 2

I. "IN THE NAME OF THE FATHER AND OF THE SON AND OF THE HOLY SPIRIT"


232 Christians are baptized "in the name of the Father and of the Son and of the Holy Spirit"53 Before receiving the sacrament, they respond to a three-part question when asked to confess the Father, the Son and the Spirit: "I do." "The faith of all Christians rests on the Trinity."54

233 Christians are baptized in the name of the Father and of the Son and of the Holy Spirit: not in their names,55 for there is only one God, the almighty Father, his only Son and the Holy Spirit: the Most Holy Trinity.

234 The mystery of the Most Holy Trinity is the central mystery of Christian faith and life. It is the mystery of God in himself. It is therefore the source of all the other mysteries of faith, the light that enlightens them. It is the most fundamental and essential teaching in the "hierarchy of the truths of faith".56 The whole history of salvation is identical with the history of the way and the means by which the one true God, Father, Son and Holy Spirit, reveals himself to men "and reconciles and unites with himself those who turn away from sin".57

235 This paragraph expounds briefly (I) how the mystery of the Blessed Trinity was revealed, (II) how the Church has articulated the doctrine of the faith regarding this mystery, and (III) how, by the divine missions of the Son and the Holy Spirit, God the Father fulfils the "plan of his loving goodness" of creation, redemption and sanctification.

236 The Fathers of the Church distinguish between theology (theologia) and economy (oikonomia). "Theology" refers to the mystery of God's inmost life within the Blessed Trinity and "economy" to all the works by which God reveals himself and communicates his life. Through the oikonomia the theologia is revealed to us; but conversely, the theologia illuminates the whole oikonomia. God's works reveal who he is in himself; the mystery of his inmost being enlightens our understanding of all his works. So it is, analogously, among human persons. A person discloses himself in his actions, and the better we know a person, the better we understand his actions.

237 The Trinity is a mystery of faith in the strict sense, one of the "mysteries that are hidden in God, which can never be known unless they are revealed by God".58 To be sure, God has left traces of his Trinitarian being in his work of creation and in his Revelation throughout the Old Testament. But his inmost Being as Holy Trinity is a mystery that is inaccessible to reason alone or even to Israel's faith before the Incarnation of God's Son and the sending of the Holy Spirit.

II. THE REVELATION OF GOD AS TRINITY

The Father revealed by the Son

238 Many religions invoke God as "Father". the deity is often considered the "father of gods and of men". In Israel, God is called "Father" inasmuch as he is Creator of the world.59 Even more, God is Father because of the covenant and the gift of the law to Israel, "his first-born son".60 God is also called the Father of the king of Israel. Most especially he is "the Father of the poor", of the orphaned and the widowed, who are under his loving protection.61

239 By calling God "Father", the language of faith indicates two main things: that God is the first origin of everything and transcendent authority; and that he is at the same time goodness and loving care for all his children. God's parental tenderness can also be expressed by the image of motherhood,62 which emphasizes God's immanence, the intimacy between Creator and creature. the language of faith thus draws on the human experience of parents, who are in a way the first representatives of God for man. But this experience also tells us that human parents are fallible and can disfigure the face of fatherhood and motherhood. We ought therefore to recall that God transcends the human distinction between the sexes. He is neither man nor woman: he is God. He also transcends human fatherhood and motherhood, although he is their origin and standard:63 no one is father as God is Father.

240 Jesus revealed that God is Father in an unheard-of sense: he is Father not only in being Creator; he is eternally Father by his relationship to his only Son who, reciprocally, is Son only in relation to his Father: "No one knows the Son except the Father, and no one knows the Father except the Son and any one to whom the Son chooses to reveal him."64

241 For this reason the apostles confess Jesus to be the Word: "In the beginning was the Word, and the Word was with God, and the Word was God"; as "the image of the invisible God"; as the "radiance of the glory of God and the very stamp of his nature".65

242 Following this apostolic tradition, the Church confessed at the first ecumenical council at Nicaea (325) that the Son is "consubstantial" with the Father, that is, one only God with him.66 The second ecumenical council, held at Constantinople in 381, kept this expression in its formulation of the Nicene Creed and confessed "the only-begotten Son of God, eternally begotten of the Father, light from light, true God from true God, begotten not made, consubstantial with the Father".67

The Father and the son revealed by the spirit

243 Before his Passover, Jesus announced the sending of "another Paraclete" (Advocate), the Holy Spirit. At work since creation, having previously "spoken through the prophets", the Spirit will now be with and in the disciples, to teach them and guide them "into all the truth".68 The Holy Spirit is thus revealed as another divine person with Jesus and the Father.

244 The eternal origin of the Holy Spirit is revealed in his mission in time. the Spirit is sent to the apostles and to the Church both by the Father in the name of the Son, and by the Son in person, once he had returned to the Father.69 The sending of the person of the Spirit after Jesus' glorification70 reveals in its fullness the mystery of the Holy Trinity.

245 The apostolic faith concerning the Spirit was confessed by the second ecumenical council at Constantinople (381): "We believe in the Holy Spirit, the Lord and giver of life, who proceeds from the Father."71 By this confession, the Church recognizes the Father as "the source and origin of the whole divinity".72 But the eternal origin of the Spirit is not unconnected with the Son's origin: "The Holy Spirit, the third person of the Trinity, is God, one and equal with the Father and the Son, of the same substance and also of the same nature. . . Yet he is not called the Spirit of the Father alone,. . . but the Spirit of both the Father and the Son."73 The Creed of the Church from the Council of Constantinople confesses: "With the Father and the Son, he is worshipped and glorified."74

246 The Latin tradition of the Creed confesses that the Spirit "proceeds from the Father and the Son (filioque)". the Council of Florence in 1438 explains: "The Holy Spirit is eternally from Father and Son; He has his nature and subsistence at once (simul) from the Father and the Son. He proceeds eternally from both as from one principle and through one spiration... And, since the Father has through generation given to the only-begotten Son everything that belongs to the Father, except being Father, the Son has also eternally from the Father, from whom he is eternally born, that the Holy Spirit proceeds from the Son."75

247 The affirmation of the filioque does not appear in the Creed confessed in 381 at Constantinople. But Pope St. Leo I, following an ancient Latin and Alexandrian tradition, had already confessed it dogmatically in 447,76 even before Rome, in 451 at the Council of Chalcedon, came to recognize and receive the Symbol of 381. the use of this formula in the Creed was gradually admitted into the Latin liturgy (between the eighth and eleventh centuries). the introduction of the filioque into the Niceno-Constantinopolitan Creed by the Latin liturgy constitutes moreover, even today, a point of disagreement with the Orthodox Churches.

248 At the outset the Eastern tradition expresses the Father's character as first origin of the Spirit. By confessing the Spirit as he "who proceeds from the Father", it affirms that he comes from the Father through the Son.77 The Western tradition expresses first the consubstantial communion between Father and Son, by saying that the Spirit proceeds from the Father and the Son (filioque). It says this, "legitimately and with good reason",78 for the eternal order of the divine persons in their consubstantial communion implies that the Father, as "the principle without principle",79 is the first origin of the Spirit, but also that as Father of the only Son, he is, with the Son, the single principle from which the Holy Spirit proceeds.80 This legitimate complementarity, provided it does not become rigid, does not affect the identity of faith in the reality of the same mystery confessed.

III. THE HOLY TRINITY IN THE TEACHING OF THE FAITH

The formation of the Trinitarian dogma

249 From the beginning, the revealed truth of the Holy Trinity has been at the very root of the Church's living faith, principally by means of Baptism. It finds its expression in the rule of baptismal faith, formulated in the preaching, catechesis and prayer of the Church. Such formulations are already found in the apostolic writings, such as this salutation taken up in the Eucharistic liturgy: "The grace of the Lord Jesus Christ and the love of God and the fellowship of the Holy Spirit be with you all."81

250 During the first centuries the Church sought to clarify her Trinitarian faith, both to deepen her own understanding of the faith and to defend it against the errors that were deforming it. This clarification was the work of the early councils, aided by the theological work of the Church Fathers and sustained by the Christian people's sense of the faith.

251 In order to articulate the dogma of the Trinity, the Church had to develop her own terminology with the help of certain notions of philosophical origin: "substance", "person" or "hypostasis", "relation" and so on. In doing this, she did not submit the faith to human wisdom, but gave a new and unprecedented meaning to these terms, which from then on would be used to signify an ineffable mystery, "infinitely beyond all that we can humanly understand".82

252 The Church uses (I) the term "substance" (rendered also at times by "essence" or "nature") to designate the divine being in its unity, (II) the term "person" or "hypostasis" to designate the Father, Son and Holy Spirit in the real distinction among them, and (III) the term "relation" to designate the fact that their distinction lies in the relationship of each to the others.

The dogma of the Holy Trinity

253 The Trinity is One. We do not confess three Gods, but one God in three persons, the "consubstantial Trinity".83 The divine persons do not share the one divinity among themselves but each of them is God whole and entire: "The Father is that which the Son is, the Son that which the Father is, the Father and the Son that which the Holy Spirit is, i.e. by nature one God."84 In the words of the Fourth Lateran Council (1215), "Each of the persons is that supreme reality, viz., the divine substance, essence or nature."85

254 The divine persons are really distinct from one another. "God is one but not solitary."86 "Father", "Son", "Holy Spirit" are not simply names designating modalities of the divine being, for they are really distinct from one another: "He is not the Father who is the Son, nor is the Son he who is the Father, nor is the Holy Spirit he who is the Father or the Son."87 They are distinct from one another in their relations of origin: "It is the Father who generates, the Son who is begotten, and the Holy Spirit who proceeds."88 The divine Unity is Triune.

255 The divine persons are relative to one another. Because it does not divide the divine unity, the real distinction of the persons from one another resides solely in the relationships which relate them to one another: "In the relational names of the persons the Father is related to the Son, the Son to the Father, and the Holy Spirit to both. While they are called three persons in view of their relations, we believe in one nature or substance."89 Indeed "everything (in them) is one where there is no opposition of relationship."90 "Because of that unity the Father is wholly in the Son and wholly in the Holy Spirit; the Son is wholly in the Father and wholly in the Holy Spirit; the Holy Spirit is wholly in the Father and wholly in the Son."91

256 St. Gregory of Nazianzus, also called "the Theologian", entrusts this summary of Trinitarian faith to the catechumens of Constantinople:

Above all guard for me this great deposit of faith for which I live and fight, which I want to take with me as a companion, and which makes me bear all evils and despise all pleasures: I mean the profession of faith in the Father and the Son and the Holy Spirit. I entrust it to you today. By it I am soon going to plunge you into water and raise you up from it. I give it to you as the companion and patron of your whole life. I give you but one divinity and power, existing one in three, and containing the three in a distinct way. Divinity without disparity of substance or nature, without superior degree that raises up or inferior degree that casts down. . . the infinite co-naturality of three infinites. Each person considered in himself is entirely God. . . the three considered together. . . I have not even begun to think of unity when the Trinity bathes me in its splendour. I have not even begun to think of the Trinity when unity grasps me. .92

IV. THE DIVINE WORKS AND THE TRINITARIAN MISSIONS

257 "O blessed light, O Trinity and first Unity!"93 God is eternal blessedness, undying life, unfading light. God is love: Father, Son and Holy Spirit. God freely wills to communicate the glory of his blessed life. Such is the "plan of his loving kindness", conceived by the Father before the foundation of the world, in his beloved Son: "He destined us in love to be his sons" and "to be conformed to the image of his Son", through "the spirit of sonship".94 This plan is a "grace [which] was given to us in Christ Jesus before the ages began", stemming immediately from Trinitarian love.95 It unfolds in the work of creation, the whole history of salvation after the fall, and the missions of the Son and the Spirit, which are continued in the mission of the Church.96

258 The whole divine economy is the common work of the three divine persons. For as the Trinity has only one and the same natures so too does it have only one and the same operation: "The Father, the Son and the Holy Spirit are not three principles of creation but one principle."97 However, each divine person performs the common work according to his unique personal property. Thus the Church confesses, following the New Testament, "one God and Father from whom all things are, and one Lord Jesus Christ, through whom all things are, and one Holy Spirit in whom all things are".98 It is above all the divine missions of the Son's Incarnation and the gift of the Holy Spirit that show forth the properties of the divine persons.

259 Being a work at once common and personal, the whole divine economy makes known both what is proper to the divine persons, and their one divine nature. Hence the whole Christian life is a communion with each of the divine persons, without in any way separating them. Everyone who glorifies the Father does so through the Son in the Holy Spirit; everyone who follows Christ does so because the Father draws him and the Spirit moves him.99

260 The ultimate end of the whole divine economy is the entry of God's creatures into the perfect unity of the Blessed Trinity.100 But even now we are called to be a dwelling for the Most Holy Trinity: "If a man loves me", says the Lord, "he will keep my word, and my Father will love him, and we will come to him, and make our home with him":101

O my God, Trinity whom I adore, help me forget myself entirely so to establish myself in you, unmovable and peaceful as if my soul were already in eternity. May nothing be able to trouble my peace or make me leave you, O my unchanging God, but may each minute bring me more deeply into your mystery! Grant my soul peace. Make it your heaven, your beloved dwelling and the place of your rest. May I never abandon you there, but may I be there, whole and entire, completely vigilant in my faith, entirely adoring, and wholly given over to your creative action.102

IN BRIEF

261 The mystery of the Most Holy Trinity is the central mystery of the Christian faith and of Christian life. God alone can make it known to us by revealing himself as Father, Son and Holy Spirit.

262 The Incarnation of God's Son reveals that God is the eternal Father and that the Son is consubstantial with the Father, which means that, in the Father and with the Father the Son is one and the same God.

263 The mission of the Holy Spirit, sent by the Father in the name of the Son (⇒ Jn 14:26) and by the Son "from the Father" (⇒ Jn 15:26), reveals that, with them, the Spirit is one and the same God. "With the Father and the Son he is worshipped and glorified" (Nicene Creed).

264 "The Holy Spirit proceeds from the Father as the first principle and, by the eternal gift of this to the Son, from the communion of both the Father and the Son" (St. Augustine, De Trin. 15, 26, 47: PL 42, 1095).

265 By the grace of Baptism "in the name of the Father and of the Son and of the Holy Spirit", we are called to share in the life of the Blessed Trinity, here on earth in the obscurity of faith, and after death in eternal light (cf. Paul VI, CPG # 9).

266 "Now this is the Catholic faith: We worship one God in the Trinity and the Trinity in unity, without either confusing the persons or dividing the substance; for the person of the Father is one, the Son's is another, the Holy Spirit's another; but the Godhead of the Father, Son and Holy Spirit is one, their glory equal, their majesty coeternal" (Athanasian Creed: DS 75; ND 16).

267 Inseparable in what they are, the divine persons are also inseparable in what they do. But within the single divine operation each shows forth what is proper to him in the Trinity, especially in the divine missions of the Son's Incarnation and the gift of the Holy Spirit.

Excerpt from Chapters 14-19 of REALITY—A Synthesis Of Thomistic Thought by Reginald Garrigou-Lagrange, O. P.

CH14: THE DIVINE PROCESSIONS


1. Generation

Following revelation, particularly as recorded in St. John's prologue, St. Thomas shows that there is in God an intellectual procession, "an intellectual emanation of the intelligible Word from the speaker of that Word." [518]. This procession is not that of effect from cause (Arianism): nor that of one subjective mode from another (Modalism). This procession is immanent in God, but is a real procession, not merely made by our mind, a procession by which the Word has the same nature as has the Father. "That which proceeds intellectually (ad intra) has the very nature of its principle, and the more perfectly it proceeds therefrom the more perfectly it is united to its principle." [519] This is true even of our own created ideas, which become more perfect by being more perfectly united to our intellect. Thus the Word, conceived from eternity by the Father, has no other nature than that of the Father. And the Word is not like our word, accidental, but substantial, because God's act of knowledge is not an accident, but self-subsisting substance.

In Contra Gentes St. Thomas devotes long pages to this argument of appropriateness. The principle is thus formulated: "The higher the nature, the more intimately is its emanation united with it." [520] He illustrates by induction. Plant and animal beget exterior beings which resemble them, whereas human intelligence conceives a word interior to it. Yet this word is but a transient accident of our spirit, where thought follows after thought. In God, the act of understanding is substantial, and if, as revelation says, that act is expressed by Word, that Word must itself be substantial. It must be, not only the idea of God, but God Himself. [521].

Under this form St. Thomas keeps an ancient formula, often appealed to by the Augustinians, in particular by St. Bonaventure. It runs thus: Good is essentially self-diffusive. [522] The greater a good is, the more abundantly and intimately does it communicate itself. [523] The sun spreads light and heat. The plant, the animal, beget others of their kind. The sage communicates wisdom, the saint causes sanctity. Hence God, the infinite summit of all that is good, communicates Himself with infinite abundance and intimacy, not merely a participation in being, life, and intelligence, as when He creates stone, plant, animal, and man, not even a mere participation of His own nature, as when He creates sanctifying grace, but His own infinite and indivisible nature. This infinite self-communication in the procession of the Word reveals the intimacy and fullness of the scriptural sentence: "My Son art Thou, this day I beget Thee." [524].

Further, [525] this procession of the only-begotten [526] Son is rightly called generation. The living thing, born of a living thing, receives a nature like that of its begetter, its generator. In the Deity, the Son receives that same divine nature, not caused, but communicated. Common speech says that our intellect conceives a word. This act of conception is the initial formation of a living thing. But this conception of ours does not become generation, because our word is, not a substance, but an accident, so that, even when a man mentally conceives his own substantial self, that conception is still but an accidental similitude of himself, whereas the divine conception, the divine Word, is substantial, is not merely a similitude of God, but is God. Divine conception, then, is rightly called generation. Intellectual conception, purified from all imperfection, is an "intellectual generation," just as corporeal conception terminates in corporeal generation.

In this argument we have the highest application of the method of analogy. The Word of God, far from being a mere representative similitude of God the Father, is substantial like the Father, is living like the Father, is a person as is the Father, but a person distinct from the Father. [527].

2. Spiration

There is in God a second procession, by the road of love, as love in us proceeds from the knowledge of good. [528] But this second procession is not a generation, [529] because love, in contrast with knowledge, does not make itself like its object, but rather goes out to its object. [530].

These two processions alone are found in God, as in us intelligence and love are the only two forms of our higher spiritual activity. [531] And in God, too, the second procession, spiration, presupposes the first, generation, since love derives from knowledge.

Further on St. Thomas [532] solves some difficulties inherent in St. Augustine's teaching on the divine processions. The three persons, he shows, have in common one and the same essential act of intellect, but it is the Father only who speaks the Word, a Word adequate and hence unique. To illustrate: Of three men faced with a difficult problem, one pronounces the adequate solution, while all three understand that solution perfectly. Similarly the three persons love by the same essential love, but only the Father and the Son breathe (by notional love) the Holy Spirit, who is personal love. [533] Thus love in God, whether essential or notional or personal, is always substantial.

CH15: THE DIVINE RELATIONS

If there are real processions in God, then there must also be real relations. As in the order of nature, temporal generation founds two relations, of son to father and father to son, so likewise does the eternal generation of the Word found the two relations of paternity and filiation. And the procession of love also found two relations, active spiration and "passive" spiration. [534].

Are these relations really distinct from the divine essence? No.Since in God there is nothing accidental, these relations, considered subjectively in their inherence (esse in) are in the order of substance and are identified with God's substance, essence and existence. It follows then that the three persons have one and the same existence. [535] The existence of an accident is inexistence. [536] Now in God, this inexistence of the relations is substantial, hence identified with the divine existence, hence one and unique.

This position, so simple for St. Thomas, was denied by Suarez, [537] who starts from different principles on being, essence, existence, and relation. Suarez holds that even in the created order essence is not really distinct from existence, that relation, subjectively considered, in its inexistence, in its esse in, is identified with its objective essence, its esse ad. Hence the divine relations, he argues, cannot be real, unless each has its own existence. Thus he is led to deny that in God there is only one existence. [538] This is an important divergence, similar to that on the Incarnation, where the proposition of St. Thomas, that in Christ there is only one existence, [539] is also denied by Suarez.

Those divine relations which are in mutual opposition are by this very opposition really distinct one from the other. [540] The Father is not the Son, for nothing begets itself. And the Holy Spirit is not the Father nor the Son. Yet the Father is God, the Son is God, the Holy Spirit is God. Thus, by increasing precision, we reach the formula of the Council of Florence: In God everything is one, except where relations are opposite. [541].

Here enters the saint's response to an objection often heard. The objection runs thus: Things which are really identified with one and the same third thing are identified with one another. But the divine relations and the divine persons are really identified with the divine essence. [542] Hence the divine relations and the divine persons are identified with one another.

The solution runs thus: Things which are really identified with one and the same third thing are identified with one another; yes, unless their mutual opposition is greater than their sameness with this third thing. Otherwise I must say No. To illustrate. Look at the three angles of a triangle. Are they really distinct one from the other? Most certainly. Yet each of them is identified with one and the same surface.

Suarez, [543] having a different concept of relation, does not recognize the validity of this response. Instead of admitting with St. Thomas, [544] that the three divine persons by their common inexistence (esse in): have one and the same existence (unum esse): Suarez, on the contrary, admits three relative existences. Hence his difficulty in answering the objection just now cited. He solves it thus: The axiom that things identified with one third thing are identified with one another—this axiom, he says, is true in the created order only, but not universally, not when applied to God.

Thomists reply. This axiom derives without medium from the principle of contradiction or identity, and hence, analogically indeed, but truly, holds good also in God, for it is a law of being as such, a law of all reality, a law absolutely universal, outside of which lies complete absurdity.

Thus the doctrine of St. Thomas safeguards perfectly the pre-eminent simplicity of the Deity. [545] The three persons have but one existence. Hence the divine relations do not enter into composition with the divine essence, since the three persons, constituted by relations mutually opposed, are absolutely equal in perfection. [546].

A conclusion follows from the foregoing discussion. Real relations in God are four: paternity, filiation, active spiration, "passive" spiration. But the third of these four, active spiration, while it is opposed to passive spiration, is not opposed to, and hence not really distinct from, either paternity or filiation. [547].

This doctrine, perfectly self-coherent, shows the value of St. Augustine's conception, which is its foundation and guaranty.

CH16: THE DIVINE PERSONS

Person in general is a being which has intelligence and freedom. Its classic definition was given by Boethius: Person is an individual subject with an intellectual nature. [548] Hence person, generally, is a hypostasis or a suppositum, and, specifically, a substance endowed with intelligence. [549] Further, since person signifies substance in its most perfect form, it can be found in God, if it be stripped of the imperfect mode which it has in created persons. Thus made perfect, it can be used analogically of God, analogically, but still in its proper sense, in a mode that is transcendent and pre-eminent. Further, since revelation gives us two personal names, that is, the Father and the Son, the name of the third person, of the Holy Spirit, must also be a personal name. Besides, the New Testament, in many texts, represents the Holy Spirit as a person. [550].

Now, since there are three persons in God, they can be distinct one from the other only by the three relations which are mutually opposed (paternity, and filiation, and passive spiration): because, as has been said, all else in God is identical.

These real relations, since they are subsistent (not accidental): and are, on the other hand, incommunicable (being opposed): can constitute the divine persons. In these subsistent relations we find the two characteristics of person: substantiality and incommunicability.

A divine person, then, according to St. Thomas and his school, is a divine relation as subsistent. [551] Elsewhere the saint gives the following definition: [552] A divine person is nothing else than a relationally distinct reality, subsistent in the divine essence.

These definitions explain why there are in God, speaking properly, not metaphorically, three persons, three intellectual and free subjects, though these three have the same identical nature, though they understand by one and the same intellective act, though they love one another by one and the same essential act, and though they freely love creatures by one and the same free act of love.

Hence, while we say: The Father is God, the Son is God, the Holy Spirit is God, we also say: The Father is not the Son, and the Holy Spirit is not the Father, and the Holy Spirit is not the Son. In this sentence the verb "is" expresses real identity between persons and nature, and the negation "is not" expresses the real distinction of the persons from each other.

These three opposed relations, then, paternity, filiation, and passive spiration, belong to related and incommunicable personalities. Thus there cannot be in God many Fathers, but one only. Paternity makes the divine nature incommunicable as Father, though that divine nature can still be communicated to two other persons. To illustrate. When you are constructing a triangle, the first angle, as first, renders the entire surface incommunicable, though that same surface will still be communicated to the other two angles; and the first angle will communicate that surface to them without communicating itself, while none of the three is opposed to the surface which they have in common.

Here appears the profundity of Cajetan's [553] remark: the divine reality, as it is in itself, is not something purely absolute (signified by the word "nature") nor something purely relative (signified by the name "person"): but something transcending both, something which contains formally and eminently [554] that which corresponds to the concepts of absolute and relative, of absolute nature and relative person. Further, the distinction between nature and the persons is not a real distinction, but a mental distinction (virtual and minor): whereas the distinction between the persons is real, by reason of opposition. On this last point theologians generally agree with Thomists.

CH17: THE NOTIONAL ACTS

There are two notional acts: generation and active spiration. They are called notional because they enable us to know the divine persons better. Their explanation serves St. Thomas [555] as a kind of final synthesis, a recapitulation of Trinitarian doctrine.

Here we find the most difficult of the objections raised against that Augustinian conception which St. Thomas defends. The objection runs thus: [556] The relation called paternity is founded on active generation, hence cannot precede generation. But the personality of the Father must be conceived as preceding active generation, which is its operation. Hence the personality of the Father which precedes generation, cannot be constituted by the subsisting relation of paternity which follows generation.

In other words, we have here a vicious circle.

St. Thomas replies [557] as follows: "The personal characteristic of the Father must be considered under two aspects: first, as relation, and as such it presupposes the notional act of generation. But, secondly, we must consider the personal characteristic of the Father, not as relation, but as constitutive of His own person, and thus as preceding the notional act of generation, as person must be conceived as anterior to the person's action."

Hence it is clear that we have here no contradiction, no vicious circle, because divine paternity is considered on the one hand as anterior to the eternal act of generation, and on the other hand as posterior to that same act. Let us look at illustrations in the created order.

First, in human generation. At that one and indivisible instant when the human soul is created and infused into its body, the ultimate disposition of that body to receive that soul—does it precede or does it follow the creation of the soul? It both precedes and follows. In the order of material causality, it precedes. In all other orders of causality, formal, efficient, and final, it follows. For it is the soul which, in the indivisible moment of its creation, gives to the human body its very last disposition to receive that soul. Hence, from this point of view, that disposition is in the human body as a characteristic deriving from the soul.

Secondly, in human understanding. The sense image precedes the intellectual idea. Yet that same image, completely suited to express the new idea, follows that idea. At that indivisible instant when the thinker seizes an original idea, he simultaneously finds an appropriate image to express that idea in the sense order.

Again, in human emotion. The sense emotion both precedes and follows intellectual love, is both antecedent and consequent.

Again, still more strikingly, in human deliberation. At the terminus of deliberation, in one and the same indivisible instant, the last practical judgment precedes the voluntary choice, and still this voluntary choice, by accepting this practical judgment, makes that judgment to be the last.

Again, look at the marriage contract. The man's word of acceptance is not definitively valid before it is accepted by the woman. The man's consent thus precedes the woman's consent, and hence is not yet actually related to her consent, which has not yet been given. Only by her consent does his consent have actual matrimonial relation to his wife.

Lastly, look again at the triangle. In an equilateral triangle, the first angle drawn, though it is as yet alone, constitutes, nevertheless, the geometric figure, but does not as yet have actual relation to the two angles still undrawn.

In all these illustrations, there is no contradiction, no vicious circle. Neither is there contradiction when we say that the divine paternity constitutes the person of the Father anteriorly to the eternal act of generation, although that same paternity, as actual relation to the Son, presupposes the act of generation.

To proceed. These notional acts, generation and spiration, belong to the persons. [558] They are not free acts, but necessary, though the Father.

wills spontaneously to beget His Son, just as He spontaneously wills to be God. And active spiration proceeds indeed from the divine will, but from that will, not as free, but as natural and necessary, like our own desire of happiness. [559] Generative power belongs to the divine nature, as that nature is in the Father. [560] "Spiratory power also belongs to the divine nature, but as that nature is in both the Father and the Son. Thus the Holy Spirit proceeds from the Father and the Son as from one sole principle: [561] there is but one Breather (Spirator): though two are breathing (spirantes)." [562].

If these two powers, generative and spiritave, belonged to the divine nature as such, as common to the three persons, then each of the three persons would generate and breathe, just as each of them knows and loves. Hence the word of the Fourth Lateran Council: "It is not the essence or nature which generates, but the Father by that nature." [563] Hence the formula, [564] common among Thomists: "The power of generating signifies directly (in recto) the divine nature, indirectly (in obliquo) the relation of paternity."

What is the immediate principle (principium quo) of the divine processions? It is, so Thomists generally, the divine nature, as modified by the relations of paternity and active spiration. To illustrate. When Socrates begets a son, the principium quo of this act of generation is indeed human nature, but that nature as it is in Socrates. Were it otherwise, were human nature the principium quo, as common to all men, then all men without exception would generate, as they all desire happiness. Similarly, the surface of a triangle, as far as it is in the first angle drawn, is communicated to the second, and by the second to the third; but as it is in the third it is no longer communicable. If it were, then we would have a fourth person, and for the same reason a fifth, and thus on to infinity.

So much on Thomistic doctrine concerning the notional acts. It is in perfect harmony with the foregoing chapters.

CH18: EQUALITY AND UNION

Numeric unity of nature and existence makes the three persons perfectly equal. And unity of existence means unity of wisdom, love, and power. Thus, to illustrate, the three angles of an equilateral triangle are rigorously equal. Hence, in God, to generate is not more perfect than to be generated. The eternal generation does not cause the divine nature of the Son, but only communicates it. This divine nature, uncreated in the Father, is no less uncreated in the Son and in the Spirit. The Father is not a cause on which the Son and the Spirit would depend. He is rather a principle, from which, without dependence, the Son and the Spirit proceed, in the numerical identity of the infinite nature communicated to them.

Again to illustrate. In the equilateral triangle we have an order, of origin indeed, but not of causality. The first angle drawn is not cause, but principle, of the second, and the principle also, by the second, of the third. Each angle is equally perfect with the others. The illustration is deficient, since you may start your triangle with any angle you choose. But illustrations, however deficient, are useful to the human intellect, which does not act unless imagination cooperates.

This perfect equality of the divine persons expresses, in supreme fashion, the life of knowledge and love. Goodness, the higher it is, the more is it self-diffusive. The Father gives His infinite goodness to the Son and, by the Son, to the Holy Spirit. Hence of the three divine persons each comprehends the other with the same infinite truth and each knows the other with the same essential act of understanding. Of their love the same must be said. Each embraces the other with infinite tenderness, since in each the act of love is identified with infinite good fully possessed and enjoyed.

The three persons, purely spiritual, are thus open to possession one by the other, being distinguished only by their mutual relations. The Father's entire personality consists in His subsistent and incommunicable relation to the Son, the ego of the Son is His relation to the Father, the ego of the Holy Spirit in His relation to the first two persons.

Thus each of the three persons, since He is what He is by His relationship to the others, is united to the others precisely by what distinguishes Him from them. An illustration: recall again the three angles in a triangle. How fertile is that fundamental principle that in God everything is identically one and the same except where we find opposition by relation!

The three divine persons, lastly, are the exemplar of the life of charity. Each of them speaks to the others: All that is mine is thine, all that is thine is mine. [565] The union of souls in charity is but a reflection from the union of the divine persons: "That all may be one, as Thou, Father, in Me, and I in Thee, that they also be one in Us." [566] As Father and Son are one by nature, so the faithful are one by grace, which is a participation in the divine nature.

CH19: THE TRINITY NATURALLY UNKNOWABLE

The Trinity is a mystery essentially supernatural. St. Thomas [567] expounds the reason for this truth much more clearly than his predecessors did. By natural reason, he says, we know God only as Creator. Now God creates by His omnipotence, which is common to all three persons, as is the divine nature of which omnipotence is an attribute. Hence natural reason cannot know the distinction of persons in God, but only His one nature. In this argument we have one of the most explicit expressions of the distinction between the natural order and the supernatural order.

Hence it follows, as Thomists in general remark, that natural reason cannot positively demonstrate even the intrinsic possibility of the mystery. After the mystery is revealed, we can indeed show that it contains no manifest contradiction, but we cannot show, apodictically, by reason alone, that it contains no latent contradiction. Mysteries, says the Vatican Council, [568] cannot, by natural principles, be either understood or demonstrated.

Further. If reason alone could demonstrate, positively and apodictically, the objective possibility of the Trinity, it would likewise demonstrate the existence of the Trinity. Why? Because, in things which necessarily exist, we must, from real possibility, deduce existence. [569] If, for example, infinite wisdom is possible in God, then it exists in God.

In this matter, the possibility, namely, and the existence of the Trinity, theology can indeed give reasons of appropriateness, reasons which are profound and always fruitful, but which are not demonstrative. Theology can likewise show the falseness, or at least the inconclusiveness, [570] of objections made against the mystery. Here is a formula held by theologians generally: The possibility, and a fortiori the existence, of supernatural mysteries cannot be proved, and cannot be disproved, but can be shown to be appropriate, and can be defended against impugners. [571].

The analogies introduced to clarify the mystery rise in value when they are pointed out by revelation itself. Thus, when St. John [572] says that the only-begotten Son proceeds as God's mental Word, we are led to think that the second procession is one of love.

Excerpt from A COMPANION TO THE SUMMA, Vol. 1, Chapter VII The Inner Life of God by Fr. Walter Farrell, O.P.

Before we begin our study of the Incarnation, I thought it might be good for us to have at least an elementary understaning of The Trinity.  Aquinas discusses the Trinity in Questions 27 -43 of the Prima Pars of the Summa Theologiae.  Fr. Farrell provides a commentary to this.

To divine eyes, the mysterious inner life of God is completely clear; God can comprehend all its ineffable perfection, for the infinite alone can comprehend the infinite. This is knowledge that has been God's from all eternity and that will never belong to any other though all of an eternity be given to its contemplation and all the graciously tender thoughtfulness of God be exerted in unfolding the story to lesser minds.


We are humbled before these inscrutable truths, but not humiliated; rather we are exalted as a man of mediocre virtue is exalted by contact with heroic sanctity. What a tragic thing it would be if his paltry virtue were the highest peak to which the heart of man could aspired What a traffic, desperate thing it would be if our paltry minds could encompass all truth! What an inspiring thing it is for the heart of a man to know that there is inexhaustible beauty beyond the faint shadow that he can perceive; what an incredibly gracious thing it is that man should be given, as far as he can be given, the eyes of God to see beyond the shadow into the infinite reality!

As told to man by God


Statement of the mystery of the Trinity

For God has not spoken of His mysteries in guarded whispers behind the locked gates of heaven; He has shared them, as far as they can be shared, with the least of intellects, the intellect of man. He has told us something of that ineffable inner life of His; and that something is almost too much for our minds to bear, like a joy that crowds the heart to the breaking point. The mystery of the Trinity, as God has told it to us, is the mystery of three divine persons, really distinct, in one and the same divine nature: coequal, coeternal, consubstantial, one God. Of these persons, the Second proceeds from the First by an eternal generation; the Third proceeds from the First and the Second by an eternal spiration.

Sole source of this knowledge

There is absolutely no way in which we could have come to this knowledge of ourselves. It had to be told us by God. It is told vaguely, dimly in the obscure words of the Old Testament, as though to prepare the mind for the terrific impact of so great a truth; then, in the New Testament, there is the clear statement both of the trinity of persons and their identity of nature; finally, in the declarations of the Church, the mystery is stated with a clear-cut brevity that staggers the mind. This is the only source of our knowledge of the Blessed Trinity -- - the authority of God -- only God could know of it, only God could tell of it; He has told us and we bend our minds in humbly grateful belief.

Validity of this knowledge

The modern cannot understand why we accept a truth we cannot verify by our own intellects. To us, it does not seem a wisely superior thing to doubt that God, Who gave us the intellects by which we pan out flakes of golden truth, should give us nuggets beyond the capacities of our laborious panning process, indeed, beyond our wildest dreams of rich strikes. From whatever point of view we take, it is the doubt of these mysteries that needs explanation, not their belief. We can prove, and have proved, that God is supreme intelligence, the first truth; that, consequently, He is incapable of deceiving Himself or others, of being deceived by others.. Why then doubt His word? Knowledge of God arrived at by reason from the world of reality is undoubtedly valid, as we have shown; should knowledge of Cod be less valid when it comes directly from God Himself? Or, to put the same truth in simpler terms, is first hand knowledge necessarily to be classed as inferior to second hand knowledge? Yet surely the knowledge garnered from the effects of God in the world is second hand by comparison with knowledge coming directly from God. No, the fact that this knowledge comes to us as a completely free gift from God is not a reproach to its validity but a guarantee, a divine guarantee, of it.

Reason and the mystery of the Trinity


In general

The Trinity is a mystery; no doubt about it. Unless we had been told of its existence, we would never have suspected such a thing. Moreover, now that we know that there is a Trinity, we cannot understand it. The man who attempts to unravel the mystery is in the position of a near-sighted man straining his eyes from the Eastern Shore of Maryland for a glimpse of Spain. We cannot probe the depths of the ocean of divinity with the foot-rule of the human intellect.

It may feel grand to adopt a righteously indignant attitude against mysteries, snatch up a hatchet and sally forth as a crusader dedicated to smashing the dark windows behind which mystery carries on its revels. But why not start the crusade at home? Long before we have finished in nature, our hatchet will be dulled, our arm fatigued, our soul humbled enough to see that there are undreamed of truths in this world; undreamable truths in the world of divinity. What, for instance, do we know of electricity beyond the fact that it works and something of how it works? There is very much to be explained about radio beyond the mysterious selection of the dogged entertainers who use it as a medium of slipping into our houses. Over and above the realization that a red light gives us a choice between stopping our car and accepting a ticket, we know that it involves some 130,000,000 vibrations a second; but that is not much help. A culture developed from the brain or spinal cord of a mad dog will arrest the development of rabies; but no one knows why. And so on. yet we are surprised, indignantly surprised, that the divinity should propose truths beyond the capacities of our minds!

Ordinary common sense should tell us that this is a natural concomitant of the inevitable limitations of our nature. A small cup can hold only so much water; not the whole ocean. Our eyes can see only so much of the spectrum, not all of it, they can take in only so much light under pain of blindness; there are rays of light invisible to our eyes, sounds inaudible to our ears we take these limitations for granted. As our eyes are only human eyes, our ears only human ears, so our intellects are only human intellects; there are truths we cannot know by those intellects.

When such truths are made known to us by a superior intellect, there is not much we can do with them. Certainly we cannot prove them; we have little result from attempting to probe them; we can show they are not violations of reason, that is that they do not involve contradictions, and we can dig up a few clumsy illustrations. Thus, for instance, we can show that the idea of three persons in one nature is not inconceivable, it is not the contradictory statement that the same thing is at the same time one and three. As a matter of fact, the exclusion of this often alleged contradiction against the truth of the Trinity is absurdly simple; all it involves is the manifestation of the fact that there is a distinction between person and nature. In the construction of a cross-word puzzle, the principle by which the puzzle was drawn up is a human nature, but the principle who drew up the puzzle was John Jones. The first answers the question why such a thing was possible -- - no other nature engages in such activities; the second answers the question who did the work involved. The distinction is fairly obvious from a normal man's resentment of the inference that he is any less identically human than any other man as contrasted with his assured knowledge that there is no identity between his person and the person of any other man who has ever existed.

In the mystery of the Trinity, the persons are distinct from each other; but each one is identical with the divine nature, Here the question is not one of conceptual possibility -- - assured by our perception of the distinction of person and nature in the world about us -- but of fact. Is this not a violation of the mathematical principle that two things equal to a third are equal to each other? The Father is not distinct from the divine nature, the Son is not distinct from the divine nature: therefore the Father is not distinct from the Son. The revealed truth is that though Father and Son are not distinct from the divine nature, they are distinct from each other; nor does that truth violate the mathematical principle in question here. Perhaps we can see the root of the confusion if we reflect that the qualities of action and passion are the same as immanent, but not the same as each other; for example, a blow in the face as given and the blow as received are the same as immanent, i.e. at the point of contact, but they are certainly distinct from each other under their own proper and formal conception. The Son, precisely as Son, is distinct from the Father, precisely as Father; though both are identical with the divine nature.

By way of illustration we hit upon such clumsy things as the merging of three flames into a single flame; the light of a candle, which is red, yellow and blue, yet one light; or the trunk of a tree springing from the roots and the fruit coming from both root and trunk, yet all three make up one tree. These are clumsy examples, examples that limp so badly that they are a hindrance, rather than a help, to the tranquillity of our restless intellects. As has been insisted throughout this chapter, human reason cannot get much done with truths that are entirely proper to the mind of God. Perhaps the best procedure, in dealing with the Trinity, would be to single out the basic theological terms, subject them to analysis and illustration, so that we might be able to achieve an accurate statement of the mystery and maintain our slender intellectual foothold on the flowering truth of three divine persons in one divine nature.

Basis of the distinction of persons -- the processions

These basic terms, which enter into the very revelation of the mystery, can be reduced to three: processions of origin, subsistent relations, and person. Examining each of these in order we shall at least come to a knowledge of what the mystery of the Trinity does not involve and of what, therefore, we are precisely to believe in believing that mystery.

By faith we know that the Son proceeds from the Father, the Holy Ghost from the Father and the Son; that is, the Father is the principle of the Son, the Father and Son are one principle of the Holy Ghost. To have distinction we must have difference; and, since there is no difference whatever on the side of nature -- - the three Persons having the numerically same divine nature -- - the sole possibility of difference lies in the processions of one person from another. To our way of thinking, a principle is the cause of a thing. We cannot comprehend how one Person can proceed from another without depending in some way or another. This is precisely the heart of the mystery; this is precisely what we shall never understand. But we can understand the meaning of the statement: the Father is not the cause of the Son, nor are the Father and Son the cause of the Holy Ghost. This is what we are to believe. There can be no relation of causality between the divine Persons for this would destroy the truth that they are all divine. The word "principle" is used because it signifies an order of origin in an absolute way, without determining a particular mode that would be foreign to the origin of the divine Persons. In a word, this term "principle" is invaluable because of its indefiniteness, because it hides a truth we cannot understand, shading our eyes from its splendor; it does not distort that truth.

Procession, here, is not to be understood in the sense in which a word proceeds from a man's mouth to wander up and down the world, but, analogically, as an idea proceeds from the mind of a man but stays in his head. The divine processions are not processions to the outside but within divinity itself, with all that perfection of immanency that is uniquely God's.

Procession, then, in God is not as it is in the lowest creatures, that is, either by way of local movement or by way of cause proceeding to exterior effects. Rather it is in the order of the most perfect activity in its most perfect form, intellectual activity. In this order, what proceeds is not necessarily distinct from its source; indeed, the more perfectly it proceeds, the more closely it is one with its source, for the more perfect it is, the more immanent it is. The faith teaches us there are two of these processions in God: that of generation, by which the Son proceeds from the Father; and that of spiration, by which the Holy Ghost proceeds from the Father and the Son as from a common principle. We shall touch upon these again at a somewhat greater length later on in this chapter.

Reality of the relations set up by the processions

The point to be noted here is that these two processions set up relationships in God: the double relationship of paternity and filiation arising from generation; and the double relationship of active and passive spiration arising from the procession of the Holy Ghost from the Father and the Son. In our human order, a relation arising, say, from the anthropological classification of a man as Alpine, Mediterranean or Nordic, is purely a thing of the mind, a relation of reason; for it does not arise from the principles of the same nature. On the contrary, a man's relations to his end, to his acts, to his Creator are all real relations, arising from the very principles of his nature. A visitor to Washington, however short his stay, will certainly see the massive pillars of the Supreme Court building. By his glance at those pillars, a relation is set up between him and the pillars; on the side of the pillars that relation is a relation of reason, for the nature of pillars does not give rise to the relation brought about by being seen. In the divine order, the relations of paternity, filiation, active and passive spiration are real, not rational, relations, arising from the numerically same divine nature. As real they are distinct terms: paternity is not the same as filiation, nor is active spiration the same as passive spiration. They are real, they are intimately opposed, and, as entirely distinct from any relation in the created world, they subsist. The opposing relationships constitute the three divine persons: Father, Son and Holy Ghost. Only by such opposition of origin is there distinction in divine things; there are then, not four, but three divine persons since there is no opposition between active spiration and the relations set up by generation.

All this is, of course, impossible to understand. The whole purpose of this exposition was not to make the mystery intelligible but rather to make clear wherein the mystery lies that our faith might embrace it. Nevertheless, our intellects are a restless, rowdy, independent lot; they chafe under the restraint of the incomprehensible, even though that restraint in reality be a release from the chains of the natural into the unsuspected freedom of the truths proper to God. The irritation is far from logical; but it is none the less quite universally human. If we can get some little grip on a mystery, even though it is by no more than our finger-nails, we feel very much better. It was perhaps in recognition of this childish stubbornness which is so common a human weakness that God moved men to conceive the most celebrated illustration of the trinity.

The classical illustration

It is to be remembered, however, that this is only an illustration; it is not to be taken literally, univocally. It limps because it compares the divine to the human; but it does give us that finger-nail grip so necessary to pride. It goes like this. Life is activity. In the created world, it is a process of change, a process of attaining perfection or of using perfection attained. But throughout its keynote is immanency. The more perfect the immanency, the more perfect the life. The highest life, and consequently the most immanent activity, we know is intellectual. Coming to the absolutely perfect life of God, we can expect activity, the highest, the most perfect activity; hence activity of the most sublime immanency. Both from the fact of the perfection of the immanency of this activity and from the fact that God is pure intelligence, we can expect that His activity is intellectual activity, of which there are, to talk in our human fashion, only two principles: the intellect and the will.

The entirely immanent activity, then, from the side of the intellect of God, will be the knowledge of God, God knowing Himself. This knowledge depends in no way on anything or anyone outside of divinity, it is not measured; it proceeds to a term -- - God known -- - which is utterly perfect because utterly immanent. God knowing Himself is the principle from which proceeds the eternal Word of God, God known.

On the side of the will, which in us follows on knowledge, there is the eternal and immanent act of God's love. God, eternally knowing Himself perfectly with sublime immanence, generates the eternal Word, the Son, the perfection of the Father; the eternal and immanent breath of love of the Son for the Father and the Father for the Son is the Holy Ghost, the sign of divine love that subsists. The perfect immanency of these acts insists that no one of these three is distinct from the divine essence but entirely identical with it; the opposition of the relationships insists that they are distinct one from another. They are one God and three divine persons: consubstantial, coeternal, coequal.

The divine persons

Father, Son and Holy Ghost are not called persons by a kind of poetic license; this is not figurative speech. They are persons. This is one point we can see clearly by clarifying our own notion of what a person is, shearing away the accidentals that the essential might stand out. A person, to put it as briefly as possible, is an individual intellectual substance, whatever kind of intellectual substance or in whatever way distinguished from other persons of the same nature; thus there are human persons, angelic persons, divine persons. The human person subsists in a human nature and is distinguished from all other human persons in the way proper to human nature, that is by signate matter; an angelic person subsists in an angelic nature and is distinguished from all other angelic persons in the way proper to angelic nature, that is, by a specific distinction; a divine person subsists in a divine nature and is distinguished from other divine persons in the way proper to divinity, that is, by the opposition of the relations of origin.

Sometimes we give these divine persons names that belong to them by reason of their divine nature; such names, for instance, as almighty, good, merciful. These names belong, not to any one person, but to all three for the numerically identical divine nature is common to all three. At other times, we address the divine persons by names that belong to them, not by reason of the divine nature, but by reason of the opposition of the relations of origin; such names, for instance, as Father, Son, Holy Ghost. These are completely proper names: the name of the Son cannot be given to the Holy Ghost, for title to it is by the relation of filiation which is proper to the Son alone. It is worth noting that when we say the "Our Father" we are addressing the whole Trinity, not merely the first Person; for God is our Father, not by the eternal generation of the Son, but by creation which, like all external operations, is common to the three Persons.

One of the most reassuring things about the mystery of the Trinity is its incomprehensibility. It is grand to have so concrete an assurance that our minds do not tell the whole glorious story of intelligence, that the crumbs of truth we amass so laboriously are only crumbs, not the sum total of truth's banquet, that the feeble glow which hardly lights up a path for our own steps is not the light of the world. The concrete assurance of this incomprehensibility comes to the solitary human mind like the comfort of a lost child's discovery of its parents; with a joy too big for words and too deep for laughter, with rekindled hopes and the utter, unquestioning, eager surrender of faith.

Conclusion

Some children, however, seem to have been born disillusioned. Someone has told them the truth about Santa Claus and now they spend their days in pouting. They are determined to be happy with the introduction to the story of intelligence, to be surfeited with the crumbs of truth, to light up the world with the match they have just blown out. They will get along without God and His incomprehensible mysteries, above all they will have nothing to do with the Trinity. Yet they never quite make their renunciation stick. Though they abolish God and the Trinity, they make a travesty on the divinity and the divine persons.
