The Divine Trinity: A Dogmatic Treatise
By Joseph Pohle and Arthur Preuss
()
About this ebook
It belongs to the first treatise of Dogmatic Theology (De Deo Uno) to show that God is one and personal. The pantheistic fiction of an impersonal God is sufficiently exploded by the Almighty’s own solemn declaration (Gen. 3:14): “I am Who am.”1
Whether the infinite personality of God must be conceived as simple or multiplex, is a matter which human reason cannot determine unaided. On the strength of the inductive axiom, “Quot sunt naturae, tot sunt personae,” we should rather be tempted to attribute but one personality to the one Divine Nature. Positive Revelation tells us, however, that there are in God three really distinct persons: Father, Son, and Holy Ghost. This fundamental dogma, which essentially differentiates the Christian conception of God from that of the Pagans, the Jews, and the Mohammedans, is designated in the technical Latin of the Church as “Trinitas,” a term first used, so far as we know, by Theophilus of Antioch2 and Tertullian,3 and which later became current in ecclesiastical usage and was embodied in the Creeds.4 In the private symbolum of St. Gregory Thaumaturgus mention is made of a “perfect Triad” (τριὰς τελεία). Didymus the Blind, Cyril of Alexandria, Hilary, Ambrose, and Augustine have written separate treatises “On the Trinity.”

The Divine Trinity - Joseph Pohle
PART I. THE HOLY TRINITY IN UNITY, OR THE THREEFOLD PERSONALITY OF GOD1
Both the fact that (ὅτι ἔστιν), and the intrinsic reason why (διότι ἔστιν) there are Three Persons in God, is positively revealed to us in the doctrine of the innerdivine processions (Filiation and Spiration). They form part of the immediate deposit of the faith, and constitute the dogma of the Divine Trinity. We have first to prove the fact of the threefold personality of God from Sacred Scripture (Chapter I) and Tradition (Chapter II); then (Chapter III) we shall enter into a dogmatic consideration of the cause of this fact, viz.: the mysterious vital processes immanent in the Godhead which are called Filiation
and Spiration.
In a concluding Chapter (IV) we shall discuss the speculative theological development of the dogma.
Chapter I. god’s threefold personality proved from sacred scripture
There are traces of the dogma in the Old Testament, but they are rather indefinite and obscure unless viewed in the light of the New Testament. It is upon the latter, therefore, that the Scriptural argument is almost exclusively based. After briefly rehearsing the Old Testament intimations (§1), we will marshal the Trinitarian texts contained in the New Testament in a double series, first citing those which treat of all three Divine Persons together (§2), and secondly those which refer to only one of the three Divine Persons without mentioning the other two (§3). The dogma of the Holy Trinity is immutably grounded in the Unity of the Divine Essence. Accordingly, throughout the triple argument upon which we are about to enter for the purpose of tracing out the hypostatic differences of the Three Divine Persons, it will be important not to lose sight of the monotheistic foundation on which alone this dogma can be built up.
Section 1. the threefold personality of god foreshadowed in the old testament
1. Primitive Intimations of the Dogma.—Some theologians take the plural form of several of the names attributed to Jehovah182 in the Old Testament as an obscure intimation of the dogma of the Trinity.
We are not inclined to press this argument. Neither do we attach much importance to the theory of Clement of Alexandria, Origen, and Augustine, who point to the expression בְּרֵאשׁיח in Gen. 1:1 as a proof for the Logos, explaining "in principio to mean
in Verbo, i. e., Filio." Upon close scrutiny this more than doubtful interpretation turns out to be of later origin and exegetically unsupported.193 In Gen. 1:26 sq., however, we come upon what appears to be a definite allusion to the mystery of the Divine Trinity: "Faciamus hominem ad imaginem et similitudinem nostram.… Et creavit Deus hominem ad imaginem suam—Let us make man to our image and likeness.… And God created man to his own image." The hortatory subjunctive plural which heads verse 26, and is followed by an indicative verb in the singular in verse 27, cannot be taken as a pluralis maiestaticus, nor yet as addressed to the angels; for man was not created to the image of the angels, but to that of God Himself.
There is a similar passage in Gen. 11:7 sq.: Come ye, therefore, let us go down, and there confound their tongue.… And so the Lord scattered them.
204 Many theologians in this connection recall the liturgical blessing of the priests, Num. 6:24 sqq., which they regard as a parallel to the Christian formula, In the name of the Father, and of the Son, and of the Holy Ghost.
This Old Testament benediction, dictated by Yahweh Himself to Moses, is as follows: The Lord bless thee and keep thee. The Lord show his face to thee, and have mercy on thee. The Lord turn his countenance to thee and give thee peace.
The clearest allusion to the mystery of the Blessed Trinity in the Old Testament is probably the so-called Trisagion of Isaias (6:3): Holy, holy, holy, the Lord God of Hosts, all the earth is full of his glory,
which is rightly made much of by many Fathers and not a few theologians. This triple Holy
refers to an ecstatic vision of the Godhead, by which Isaias was solemnly called and consecrated as the Prophet of the Incarnate Word, an office which won for him the title of the Evangelist
among the four major prophets.215
2. The Angel of Jehovah in the Theophanies.—The various apparitions commonly known as theophanies, in which Yahweh figures both as sender and messenger, mark the gradual breaking of the dawn in the history of our dogma.
The God who is sent is called מַלְאַךְ יְחוָה, i. e., messenger, Angelus Domini, the word angelus being here employed in its literal sense of ἄγγελος, from ἀγγέλλειν, to send. Since the Angel of Jehovah
is described as יַהְוֶה, i. e., true God, we have in these theophanies two distinct persons, both of them Yahweh, the one sending
and the other sent.
An apparition of this character was the angel who spoke words of comfort to Hagar shortly before the birth of her son Ismael226 in the desert. According to Gen. 18:1 sqq., the Lord [יַהְוֶה] appeared to [Abraham] in the vale of Mambre,
in order to announce to him the destruction of Sodom and Gomorrha.237
Probably the most familiar of the Old Testament theophanies is the apparition of the Angel of Jehovah in the Burning Bush. Exod. 3:2: "Apparuit ei מַלְאַךְ יְהוֹהָ in flamma ignis de medio rubi—And the Lord appeared to him [Moses] in a flame of fire out of the midst of a bush. It is to be noted that the Lord who appears to Moses is Jehovah Himself. Exod. 3:14:
God said to Moses: I am who am. Viewing this apparition in the light of the New Testament Revelation, the appearing God can be none other than the Logos, or Son of God, because the Father cannot be
sent. True, the Holy Ghost may also be
sent; but He cannot have appeared in the bush to Moses because the prophets expressly identify the
Angel of Jehovah" with the future Messias (i. e., Christ). Cfr. Is. 9:6 (in the version of the Septuagint): "Μεγάλης βουλῆς ἄγγελος, Magni consilii angelus;" Mal. 3:1: Angelus testamenti
The interpretation here adopted is common to all the Fathers. Thus St. Hilary teaches: "Deus igitur est, qui et angelus est, quia qui et angelus Dei est, Deus est ex Deo natus. Dei autem angelus ob id dictus, quia magni consilii est angelus. Deus autem idem postea demonstratus est, ne qui Deus est esse angelus [creatus] crederetur."248
It is quite another question whether in these theophanies the Logos directly appeared as God in visible form, or through the intermediate agency of an angel. In the latter case the apparitions might with equal propriety be styled angelophanies.
St. Augustine took this view, without, however, denying the theophanic character of such angelophanies. He held that a created angel visibly appeared as the representative of God in such a manner that the words he spoke must be understood as coming not from the actual speaker but from Jehovah himself. This opinion was shared by Athanasius, Basil, Cyril of Alexandria, Eusebius, Chrysostom, Jerome, Gregory the Great, and others.259 The great majority of the Schoolmen espoused it mainly for the reason that the Second Person of the Most Holy Trinity had never appeared visibly upon earth prior to His Incarnation.1260 The first immediate theophany of the Logos, they argued, coincided with the Incarnation; therefore in the Old Testament theophanies He must have employed angels as His representatives.
3. The Future Messias as True God.—The Messianic prophecies of the Old Testament were primarily designed to emphasize the Divinity of the future Messias. Hence Christ Himself and His Apostles justly appealed to them to prove not only the divine mission but likewise the Divinity of the Saviour and the fact that He was truly the Son of God.
Among the prophets Isaias speaks most clearly and emphatically. Not only does he refer to the Messias as the Wonderful, the Counsellor, the Prince of Peace,
but also as God the Mighty, the Father of the world to come.
1271 He styles Him Emmanuel,
i. e., God with us.1282 It is expressly said of Him that God himself will come and will save you.
1293 And again: Prepare ye the way of the Lord.… Behold, the Lord God shall come with strength.
1304 His name shall be called God.
1315 In Zach. 12:10, God prophesies His own crucifixion: "Et adspicient ad me, quem confixerunt et plangent eum—And they shall look upon me, whom they have pierced; and they shall grieve over him."1326
The Messianic Psalms complete the picture outlined by the prophets; nay, they go far beyond the latter both in emphasizing the difference of persons by a contra-position of the pronouns I
and thou,
and also by indicating that the relation existing between the First and the Second Person of the Blessed Trinity is a relation of Father to Son, based upon Filiation. At the same time they do not omit to accentuate the undivided nature of both Divine Persons, which they express by the word יְהֹוָה. Thus especially Ps. 2:7: "Dominus [יְהֹוָה] dixit ad me: Filius meus es tu, ego hodie genui te—The Lord hath said to me: Thou art my son, this day I have begotten thee."1337 Similarly Ps. 109:1–3: "Dixit Dominus Domino meo [יְהֹוָה לַאדֹנִי]: sede a dexteris meis; … ex utero ante luciferum genui te—The Lord said to my Lord: Sit thou at my right hand … from the womb before the day star I begot thee.1348 If the future Messias is the
Son of God, and at the same time Jehovah, it is obvious that there must also be a
Father" who is Jehovah. Consequently, there must be two Divine Persons in one Divine Nature. This notion was so familiar to the Jews that Jesus, in order to prove His Divinity, had merely to advert to the fact that He was the Son of God to provoke them to anger and blasphemy.1359 They well knew that to admit His Divine Sonship was tantamount to recognizing His Divinity.2360
4. The Teaching of the Sapiential Books.—A great step towards the complete unfolding of the mystery is made by the Sapiential Books.2371 There we find the notion of Hypostatic Wisdom closely blended with that of Filiation, and are given to understand that the Filiation which takes place within the Godhead is a purely spiritual process, and that He Who is begotten by God
must be essentially conceived as Begotten Wisdom
(Logos).
The Sapiential Books speak of Uncreated, Divine Wisdom in a manner which leaves no doubt that they mean more than a personified attribute. The following texts read like parallel passages to certain verses of St. John’s Gospel. Prov. 8:24 sqq. "Nondum erant abyssi et ego [i. e., sapientia] iam concepta eram: … ante colles [i. e., ab aeterno] ego parturiebar.… Cum eo [scil. Deo] eram, cuncta componens et delectabar per singulos dies, ludens coram eo omni tempore, ludens in orbe terrarum, et deliciae meae esse cum filiis hominum—The depths were not as yet, and I [Wisdom] was already conceived … before the hills I was brought forth.… I was with him [God] forming all: and was delighted every day, playing before him at all times: and my delights [were] to be with the children of men. The subject of this passage is obviously not a divine attribute, but a Divine Person, who is called
Conceived Wisdom. The expression,
I was with him,"2382 has a parallel in John 1:1: The Word was with God
(Verbum erat apud Deum; πρὸς τὸν Θεόν). The Book of Wisdom,2393 in designating Divine Wisdom as a vapor of the power of God
(vapor virtutis Dei), a certain pure emanation of glory
(emanatio claritatis), the brightness of eternal light
(candor lucis), the unspotted mirror of God’s majesty
(speculum maiestatis), the image of his goodness
(imago bonitatis), reminds one of the manner in which St. Paul characterizes Christ’s relationship to God the Father,2404 i. e., as the brightness of his glory, and the figure of his substance
(splendor gloriae et figura substantiae eius). The following sentence,2415 "And thy wisdom with thee, which knoweth thy works, which then also was present when thou madest the world—Et tecum (μετά σον) sapientia tua, quae novit opera tua, quae et affuit tunc, quum orbem terrarum faceres (πάρουσα ὅτε ἐποίεις τὸν κόσμον), is again distinctly Johannine in style and sentiment. The same impression is conveyed by Ecclus. 24:5:
I came out of the mouth of the most High [as the Word], the firstborn before all creatures."2426
In view of this striking concordance between the Sapiential Books of the Old Testament and the Gospel of St. John, it is not astonishing that certain learned Jewish rabbis at a later period elaborated an independent theory of the Word of God,
called Memrah,2437 by which they endeavored to explain the Old Testament teaching regarding Wisdom without any reference to Christ.2448 It is easy to see, too, why the Fathers of the Nicene epoch appealed to the Sapiential Books of the Old Testament to prove the Consubstantiality and consequent Divinity of Christ. The Arians, on their part, quoted the Sapiential Books in support of their heretical tenet that the Logos was a creature.2459
5. The Holy Ghost.—The Old Testament references to the Third Person of the Blessed Trinity are neither as plain nor as definite as the texts relating to the Son. It is natural to expect more references to the Son than to the Holy Ghost in the Old Testament, because it prepares and announces the coming and manifestation of the Son in the Incarnation.
3460 The Old Testament references to the Holy Ghost can nearly all of them be explained as personifications. "Spiritus Dei may merely mean a breath of the Divine Omnipotence,3471 or the supernatural effects of the spirit of God, which, according to Ps. 103:30,
renews the face of the earth. The Fathers in their exegetical works quote a number of Old Testament texts in which they profess to find references to the Holy Spirit as a Person.3482 But their interpretation of these and similar passages is inspired by, and owes its impressiveness to the light derived from, the New Testament. It is in this light, too, that we must regard Wisd. 9:1 sqq., the only Old Testament passage in which the Three Divine Persons are mentioned together:
Deus patrum meorum, … qui fecisti omnia Verbo tuo, … da mihi sedium tuarum assistricem sapientiam.… Sensum autem tuum quis sciet, nisi tu dederis sapientiam et miseris Spiritum Sanctum tuum de altissimis?—God of my fathers, … who hast made all things with thy word, … give me wisdom, that sitteth by thy throne … Who shall know thy thought, except thou give wisdom, and send thy Holy Spirit from above?"
It cannot therefore be seriously maintained that the mystery of the Divine Trinity was clearly revealed in the Old Testament. Aside from certain specially enlightened individuals, such as Abraham, Moses, Isaias, and David, the Jews could not, from the more or less enigmatic hints scattered through their sacred books, have obtained a sufficiently distinct knowledge of the Blessed Trinity to make it appear as an article of faith.
Nevertheless it remains true that the Trinity was not announced in the New Testament suddenly and without preparation. On the contrary, the great mystery of the Godhead was foreshadowed from the very beginning of the Jewish Covenant and assumed more definite and luminous proportions during and after the time of David, until at last it stood fully revealed in the mystery of the Incarnation,3493 and the mission of the Holy Ghost on Pentecost Day.

Section 2. the threefold personality of god as taught in the new testament—texts treating of the three divine persons together
Though the exact terms in which the Church has formally defined the dogma of the Blessed Trinity (τριάς = trinitas, οὐσία = substantia, ὐπόστασις = persona,541 ὁμοούσιος = consubstantialis) are not in the Bible, and may, therefore, in a sense be called unscriptural; yet materially, that is in substance, they correctly express the teaching of the New Testament, which, like the Church, explicitly acknowledges three real Persons in one Divine Nature, in which precisely the dogma of the Trinity in Unity
consists.
As we are here dealing with a fundamental dogma of Christianity, the material correspondence of the New Testament doctrine with the formally defined teaching of the Church must be carefully and stringently demonstrated. We therefore proceed to a minute critical investigation of the various texts that are apt to throw light on the subject. Let us begin with those in which the threefold personality of God is distinctly and formally enunciated.
1. The Gospels.—Four such texts occur in the Gospels. Though their combined effect is sufficiently compelling, they are not all of equal weight. The most convincing is the passage embodying the form of Baptism.
a) The first brief intimation of the functioning of Three Divine Persons is given in the Annunciation: "Spiritus Sanctus superveniet in te, et virtus Altissimi obumbrabit tibi; ideoque et quod nascetur ex te sanctum, vocabitur Filius Dei—The Holy Ghost shall come upon thee, and the power of the most High shall overshadow thee. And therefore also the Holy which shall be born of thee shall be called the Son of God."552 Here all three Divine Persons are distinctly mentioned: first, the Son who is to be born, second, the Holy Ghost, and third, the Most High,
who stands in the relation of a Father to Him of whom it is said a few verses farther up:563 "Hic erit magnus et Filius Altissimi vocabitur—He shall be great, and shall be called the Son of the most High." Where there is a Son of God, there must also be a Divine Father. The relative opposition between the terms Father and Son forbids the welding of both persons into one. This is sufficient evidence that we have here not merely three different names for one Divine Person, but three really distinct Hypostases, of which one is not the other. Nor can it have been the intention of the sacred writer merely to personify certain absolute attributes of the Deity. The Son of God, who is to be made flesh (Christ), manifestly represents a real Person. Moreover, the strict monotheism of the Bible necessitates the assumption that the three Divine Persons mentioned in the text must be consubstantial, i. e., absolutely identical in essence.
b) The most glorious external manifestation of the Blessed Trinity occurred in connection with the Baptism of Christ.574 Christ, the Son of God, is standing in the Jordan; the Holy Ghost descends upon Him in the form of a dove, and the voice of the Father calls from Heaven: This is my beloved Son in whom I am well pleased.
Here, too, the hypostatic difference between the three Persons, and the impossibility of blending them into one, is quite apparent. The beloved Son
and the Father expressing His pleasure are clearly differentiated, while the Person of the Holy Ghost is emblemed by the dove, a symbolic figure which would be unsuited to any absolute attribute of the Godhead.585 Though the identity of Nature of the three Divine Persons is not expressly enunciated in the above-quoted passages, it may, as a matter of course, be presumed.
c) In His famous farewell discourse delivered after the last Supper,596 Christ announced that He was going to the Father
and would ask Him to send the Paraclete. The distinction here made between the three Divine Persons is as obvious as it is real. No one can be father and son under the same aspect, nor can any one send himself. When Christ says, for instance: "Ego rogabo Patrem, et alium Paraclitum dabit vobis, ut maneat vobiscum in aeternum, Spiritum veritatis—I will ask the Father, and He will give you another Paraclete, that he may abide with you forever, the Spirit of truth,607 He distinguishes between His own Person, that of the Father, and that of the
other Paraclete and clearly identifies the latter with the
Spirit of truth."618
The threefold personality of the Godhead appears still more distinctly from John 15:26: "Quum autem venerit Paraclitus, quem ego mittam vobis a Patre, Spiritum veritatis, qui a Patre procedit, ille testimonium perhibebit de me—But when the Paraclete cometh, whom I will send you from the Father, the Spirit of truth, who proceedeth from the Father, he shall give testimony of me. The absolute consubstantiality of Father and Son is taught in John 16:15:
Omnia, quaecumque habet Pater, mea sunt—All things whatsoever the Father hath, are mine," and it is no less true of the Holy Ghost.
d) The baptismal form, In the name of the Father, and of the Son, and of the Holy Ghost,
enunciates all the essential elements of the Holy Trinity.629 "Euntes ergo docete omnes gentes, baptizantes eos in nomine Patris et Filii et Spiritus Sancti (βαπτίζοντες αὐτοὺς εἰς τὸ ὄνομα τοῦ πατρὸς καὶ τοῦ υἱοῦ καὶ τοῦ ἁγίου πνεύματος)." The hypostatic difference between Father and Son is brought out by the relative opposition, in virtue of which they exclude each other as begetting and begotten. For no one can be his own father or his own son. To admit such an absurdity would be to deny the principle of contradiction and thereby to subvert right reason. Hence there is a real difference between the Father and the Son. As to the Holy Ghost, the co-ordination involved in the use of et—et (καί—καί) forbids us to confound Him with either of the other two Persons. Consequently He must be an independent third Person, coequal and consubstantial with the other two. It should be noted that the Johannine text does not say: "In the name of the Father, or the Son, or the Holy Ghost, but
In the name of the Father, and of the Son, and of the Holy Ghost (τοῦ πατρὸς καὶ τοῦ υἱοῦ καὶ τοῦ ἁγίου πνεύματος). The particle καί with the definite article marks off the three Divine Persons very sharply from one another, despite the unity implied between them. For this reason
Holy Ghost can not be taken as an attribute determining the concept
Son."
In attempting to answer the question, What kind of unity is it by which the Father, the Son, and the Holy Ghost are one?
we must pay special attention to the words In the name.
It makes no difference whether we follow the text of the Latin Vulgate, "In nomine," or the Greek text with its εἰς ὄνομα. Both εἰς ὄνομα and ἐν ὀνόματι, as well as ἐπὶ τῷ ὀνόματι1630 occur in the original Greek text, and for our present purpose they are equally conclusive. For man to be baptized in the name of the Most Holy Trinity can have no other meaning than that through baptism he obtains forgiveness of his sins in virtue and by the authority of the three Divine Persons; while to baptize εἰς ὄνομα of the Blessed Trinity signifies the devotion with which the person baptized is expected to consecrate himself to and to seek his last end and aim in the Deity.
