The Origin of the Persons: the Trinitarian Origins
In the introduction to the Letter to the Hebrews (1:5), when Christ's divinity is proclaimed, it refers to these words from the second psalm: “You are My Son, today I have begotten You”. Concerning the Holy Spirit, Christ says He proceeds from the Father (Jn 15:26). Based on such biblical declarations, theology began to speak of Trinitarian origins or processes (processiones trinitariae) and two forms of origin. The origin of the Son is referred to by theologians as generation or birth (generatio), and that of the Holy Spirit as simple procession or origin (processio simpliciter).
The Magisterium of the Catholic Church, through the Athanasian Creed, teaches as a dogma: "The Father is from no one, neither created nor begotten. The Son is solely from the Father, not by creation but by birth. The Holy Spirit is from the Father and the Son, not made, not created, not begotten, but proceeds" (DS 75). The Council of Florence (1439) declared as a doctrine that the Holy Spirit proceeds from the Father and the Son as from a common principle (principium) by a common spiration (spiratio) (DS 1331).
First, we must clarify the concepts expressed here, then present their biblical foundation, and finally discuss the conclusions that can be drawn from them.
The Trinitarian origins fundamentally differ from the origins, births, and processes observed in the world of creatures.
1. Since each of the Trinitarian persons is God, and God exists eternally, it's utterly impossible for any divine person to precede another in time or be a cause to the other. And since the persons possess a single nature, there can be no rank difference among them. Therefore, Trinitarian origins signify only a logical succession, meaning one person's logical rationale (ratio) and principle (principium) is different from another's. The Father is such by eternally and continuously imparting his essence to the Son, and the Son is such by eternally accepting this essence. The Holy Spirit, similarly, accepts it eternally from both the Father and the Son.
2. The earliest Church Fathers used analogies to illustrate the Son's generation. Just as rays constantly emanate from the Sun ever since the Sun existed, and as water perpetually flows from an inexhaustible source ever since the source existed; similarly, the Son is eternally begotten from the Father, since the Father exists eternally. The word “today” in Psalm 2 refers to God's "eternal present" because, in Him, there's no past or future, yesterday or tomorrow – as taught in the dogma on God's eternity. The Trinitarian origins are eternal origins. However, these analogies are only partially accurate. The Sun physically causes the rays, and the source causes the stream, but physical causality must be excluded from God: He isn't a cause of Himself (causa sui) but has a spiritual rationale (ratio sui). The given analogies also fall short because, unlike the water source that would have more water if none flowed out, the divine essence doesn't lose anything in the Trinitarian processes, neither with the birth of the Son nor with the procession of the Holy Spirit. Consequently, the Son gains nothing from being begotten, nor does the Holy Spirit from proceeding. These processes might at most bring about a different mode of existence for the same divine essence but not a change. Therefore, classic Trinitarian theology refers to these processes as substantial processes (processiones substantiales), meaning both the one proceeding and the one from whom the procession originates are God, as the processes are different modes of the same divine essence (substantia).
3. Augustine believed that since God is a spirit, we must seek a comparison not in the world of material things but in the world of spiritual processes when we want to study God's inner life. One of the most important manifestations of our spiritual life is the formation of concepts, the birth of our concepts. Just as the unspoken concept (verbum mentis) is conceived and born in our consciousness, the Son is born from the Father in the same way. The Son is actually nothing but the concept that the Father forms of himself, his self-knowledge, which on the one hand has existed eternally, and on the other hand possesses such power and intensity that it becomes a separate person. - However, since God is the infinite embodiment of all values (true, good, beautiful, holy), and values evoke spiritual love from the soul, the Father also loves himself infinitely as completeness of value, and this infinite love must be reflected in the Son. The love of the Father reflected in the Son and its reflection in the Father, its "rebound," is essentially a single and eternal love, and it is also of such intensity that it becomes a separate person, the person of the Holy Spirit.
Augustine's analogy has three advantages:
- It makes it clear that we can rightly speak of spiritual birth and origin, such as we encounter with the persons of the Trinity.
- What is born in the human soul as self-knowledge and arises as love can be "immanent" too: the originator does not "step out" of the generator, as the spoken word "steps out" of the speaker, or as the born child essentially separates from its mother. This immanence characterizes the Trinitarian origins: the life, indeed the very essence of the Son, is identical with that of the Father; he does not step out of him or separate from him in any reality; likewise, the life and essence of the Holy Spirit remain in the other two persons.
- Divine and human self-knowledge also resemble each other in that the birth of both can equally be called conception and birth. For our thoughts' conception and birth coincide in time, unlike animals' and humans' birth or conception. Therefore, these two expressions are completely synonymous: "the Father eternally begets the Son," and "the Father eternally gives birth to the Son."
Naturally, there are also essential differences between divine and human self-knowledge and self-love. Augustine already noticed these. Divine and human self-knowledge and self-love primarily differ in that our conscious self-knowledge and self-love do not exist from the first moment of our existence. Another difference is that human self-knowledge unfolds gradually and never becomes quite perfect; the same goes for our self-love. Our inner image of ourselves never fully reflects what we are. The Father, however, without any residue, perfectly "speaks" his entire essence into the Son and loves him in the Holy Spirit. The third and most significant difference is this: the intensity and power of God's self-knowledge and the mutual love of the first two persons of the Trinity are such that this knowledge and love move from the existence of thought (ens rationis) into the order of reality (becomes 'ens reale'): it becomes a real existing separate divine person, although at the same time its immanent nature is retained.
Different medieval theologians tried to develop further Augustine's explanation in various ways. Among these, classical Trinitarian theology accepted the version represented by Thomas Aquinas, and its technical expressions were used in various official statements by the Magisterium.
The theology of the Trinitarian origins teaches the following dogmas in the sense above:
WE CLAIM ABOUT THE FATHER THAT HE IS ORIGINATING AND WITHOUT BIRTH
The Scriptures attribute an origin to the other two persons but never to the Father. Early patristics used such descriptors for the Father: without beginning (anarchos), uncreated (agenétos), unborn (agennétos). This statement, however, is only linguistically negative; in substance, it proclaims the positive fact that the Father possesses the common divine essence in such a way that He does not receive it from anyone else but only gives it to the Son and, with the Son, to the Holy Spirit. The Father is "principium sine principio." He is the ultimate solution to the origin of the other two persons.
Saint Paul considers God's fatherhood so important that, as we have seen, he often refers to the Father as God. He is primarily the "Father of our Lord Jesus Christ" (2 Cor 1:3), to whom Jesus turns with feelings of submission and mutual love, not only as a human but as the second divine person; as God-man, he empties himself (Phil 2:7) and comes into the world as the Father's envoy (Jn 3:17) to reconcile the world with the Father and make men the children of God. His entire human life is childlike submission before the heavenly Father, from whom he received his divine essence, and whom he can call greater than himself in this sense (Jn 14:28). His perfect self-surrender as a man is both the model and the means by which man, although not identically, but analogously, can also become a child of the heavenly Father. For God wants to be primarily a Father to us: "For those whom He foreknew He also predestined to be conformed to the image of His Son, in order that He might be the firstborn among many brothers" (Rom 8:29; cf. Gal 3:26). The New Testament has a characteristic warmth because God spoke the final word to humanity as a Father. He sent His Son and declared through Him that He would accept humanity into His merciful love.
THE SON ORIGINATES FROM THE FATHER THROUGH GENERATION, BIRTH
This follows from the fact that the second person is not only morally but also metaphysically the son of the Father. Natural, metaphysical sonship necessarily presupposes generation or procreation. Therefore, He is the "proper" son (Rom 8:3), the "only-begotten" Son (Jn 1:14; 1Jn 4:9) of the Father. Holy Tradition, following the Letter to the Hebrews (1:5), often refers to the two expressions of the Psalms: to give birth (110:3), to give life (2:7).
The Son's generation or birth must be taken after the pattern of earthly children's procreation, but not identically, but analogously. For God is spirit, so only spiritual birth can be considered with Him. However, the analogy remains, so we must speak of a real birth. For everything is realized here that is included in the definition of earthly birth: the living comes from the living, there is a connection between the two, and the descent brings about essential identity.
When we say "verbum mentis" with Augustine, we emphasize the Son's immanence. But when we see birth in the origin of the Son, we do not emphasize immanence, but the communication, the "passing on" of identical nature.
The sonship of the second person is also very significant in the history of salvation. According to the apostle Paul, the Father created everything in Him that is in heaven and on earth, and everything stands in Him (Col 1:16-17). The Father even chose the called ones in Him before the creation of the world (Eph 1:4). For the Father constantly speaks His eternal thoughts into the Son, so the Son could be the Father's measure in the creation of the world. But for this reason, He is the founder of the Kingdom of God, He is the norm of all moral perfection, and He will also be the measure and executor of the Last Judgment. The final state will be formed in such a way that the Father will gather all created values under His dominion (Eph 1:10). The Son is also the "causa formalis" of our individual supernatural life, as the grace whose granting is the common work of the three divine persons carries over the image of sonship to the soul of the justified man. We will become children of the Father in the form in which Christ is in a filial relationship with the heavenly Father. Thus, we will share in Christ's divine sonship and become His co-heirs. And just as the Spirit connects Christ with the Father, so too the Holy Spirit will be the spirit of our filial relationship as well.
The birth of the Son is intellectual, and the origination of the Holy Spirit is a voluntary activity.
1. Not only does Augustine's analogy associate the Son's birth with the Father's intellectual activity, but Scripture also does this. The apostle Paul writes: "We preach Christ... the wisdom of God" (1 Cor 1:23-24; 2:6-9). This is further indicated by the term Word (Logos), which in the gospel of John does not mean a fleeting word or divine utterance but God Himself, who has been with the Father from eternity and became human in the fullness of time. It can also be added that according to Paul, He is "the image of the invisible God" (cf. 2 Cor 4:4; Col 1:15; Heb 1:3), in whom "all the treasures of wisdom and knowledge are hidden" (Col 2:3). Based on such biblical statements, the patristics speak of the Son as essentially the Father's intellectual image of Himself, His self-knowledge, into whom He pours His entire essence.
2. We find fewer references in the Bible to the mode of the Holy Spirit's origination. Scripture generally calls Him the Spirit, so the Church Fathers view Him as the breathed-out love between the Father and the Son. And love is a work of the will. The constant epithet "holy" also points to the will, since holiness is essentially synonymous with the love, the willing of the good. The names "gift," "present" also refer to this, as giving a gift is usually a sign of love. A true gift is always exactly the goodwill that transfers the object. If the Father and the Son love each other, this "goodwill" is personal, not an accidental reality.
Based on these, since Augustine, it has been a generally accepted theological truth that the origination of the Holy Spirit can be associated with God's voluntary activity, the love of the Father and the Son for each other. The Father and the Son love each other in the Holy Spirit. This living love and intimacy, which binds the Father to the Son and the Son to the Father, cannot be compared to any earthly love. It is entirely spiritual in nature and is not such that the two persons expect something from each other. Both possess everything. This love, therefore, is the common joy of possessing infinite value and the happiness of perfect contentment in it. In the Holy Spirit, the Father is assured that the Son is wholly His and lives in Him with His whole love. For the Son, the Holy Spirit signifies the Father's similar love for Him. The joy and intimacy of divine life take place in the Holy Spirit as the personification of divine love and joy. The liturgy refers to this life lived in joy and intimacy when it speaks of the "blessed" Trinity. In salvation history, too, the Holy Spirit is the distributor of God's love, graces, and charisms (Rom 5:5; 1 Cor 12:4). As He connects the Son with the Father, or is the personified pledge of their connection, unity, so He connects the justified person, made God's child, to the Father through the Son: "You have received the Spirit of adoption, by whom we cry, 'Abba, Father!'" (Rom 8:15).
3. If we accept the theologians' thesis that the Son's birth is intellectual to the Father, and the origination of the Holy Spirit is the common voluntary activity of the Father and the Son, then we must distinguish two kinds of intellectual and voluntary activities in God. When discussing God's cognitive activities in theology, we think of the common intellectual activities of the three divine persons. The basis of these is the common divine essence; therefore, we call this essential activity (actus essentialis). In contrast, there is the so-called person-creating divine activity (actus notionalis), in which the Father begets the Son, which is therefore not the joint activity of three persons, but only that of the Father. Similarly, we can talk about the love-activity flowing from God's essence as an actus essentialis, identical in the three persons; and we can talk about person-creating love-activity as actus notionalis, the common activity of the first two persons.
How do these two kinds of intellectual and voluntary activities differ from each other? Fatherhood, sonship, and spiration differ from each other in reality, but our point of view only distinguishes them from the common divine essence. We must apply this principle here as well. Another question is the difference in the subject of knowledge and love. The subject of the person-producing activities is one or two persons, not three; the essential activities, on the other hand, are the common activities of the three persons. We can also think that the person-creating activity is always immanent in nature, while the essential activity can also be outwardly directed, e.g., creative activity.
4. Why the Son's origin must be considered generation, and not the Holy Spirit's as well, Augustine answered this question following the Greek Church Fathers: Generation and knowledge are related in content. The natural goal of generative activity is to create one's living image from one's essence. Our intellectual activity also creates the likeness, the image of the known object in our soul. Love, on the other hand, though directed at the likeness, presupposes it. Its deepest nature is not resemblance but union. Its goal is unity.
