Subordination and Equality in the Trinity

With many things, error accompanies oversimplification; distinction is necessary to accurately articulate the truth, and without careful distinction error is practically ensured.

One such issue is subordination in respect to the Trinity, particularly in respect to the relationship between the Father and the Son. In some circles, “equality” without further specification is held at a premium, and any talk of the subordination of the Son is deemed heretical, or even Arian. On the other hand, it must be noted that among the spectrum of all mainstream schools of trinitarian thought some subordination of the Son to the Father is acknowledged in the incarnation, when the Son humbled Himself and took on a human nature.

When we look at equality and subordination in respect to the Son’s relation to the Father, I would argue that we must distinguish carefully between the three different categories of nature, headship, and causality in order to avoid falling into one sort of error or another.

Firstly, I will state my view on subordination and equality in each of these three categories, and then seek to demonstrate the truthfulness of these positions from scripture, and support the validity of these interpretations with the historical testimony of the orthodox church fathers.

In the category of nature we are dealing with essence, or substance, or genus; the broad elements that are common among many individuals. Basil of Caesarea puts it well: “The distinction between οὐσία [essence] and ὑπόστασις [person] is the same as that between the general and the particular ; as, for instance, between the animal and the particular man.” (Letter 236) In respect to nature, the Father and Son are entirely equal; this is what the Nicene Creed confesses when it say that the Son is co-essential with the Father; He has an exactly identical nature with the Father, admitting of no difference whatsoever.

We see this exegetically from scripture in two main ways. Firstly, the Son is called “God” when it says in John 1 “In the beginning was the Word, and the Word was with the God, and the Word was God.” This is not saying that the Word is the same person as “the God” Whom He is “with”, and thus distinguished from, but rather indicates His nature. There is, however, only one divine nature, since if there were multiple there could no longer truly be said to be only one God, as scripture clearly teaches. So when scripture makes known that Christ is of a divine nature, we know that it can be no other than that of the Father, exactly identical with no difference whatsoever, or else it would constitute a second divine nature.

Secondly the Son’s co-essentiality is irrefutably proven from scripture’s teaching eternal generation. “That which is born of the flesh is flesh, and that which is born of the Spirit is spirit.” (John 3:6 NKJV) Everything which begets, begets after its own kind. What is created by God from nothing, as all creation, is of a different nature than He; but that which is begotten from God’s own nature is of no other nature than He Who begat Him. As the Nicene Creed says “begotten from the Father, only-begotten, that is, from the essence of the Father, God from God, light from light, true God from true God, begotten not made, of the same essence as the Father”. That the Son is begotten of the Father is expressly indicated several times by scripture calling the Son the “only-begotten” of the Father (Jn 1:14, 18; 3:16, 18).

The Son then, as having been begotten of the Father as His true and eternal Son before the creation of the world (“Now, Father, glorify Me together with Yourself, with the glory which I had with You before the world was.” (John 17:5 NAS)) is therefore necessarily of the same divine nature as the Father. His nature is exactly identical without any inequality whatsoever. In fact, to say that the Son were subordinate to the Father in respect to His nature would be to deny His true divinity, and would be a variant of the Arian heresy.

Having looked at the first category of ‘nature’, and seeing there that the Son is equal to the Father in nature, we come to the category of headship. By headship, I mean authority. The Son eternally is subordinate to the Father as His head; this subordination is not grounded in a difference in nature, but in the personal properties of the Father and Son. The Son, as we have said, is equal to the Father in nature, having the same divine nature as He; yet inasmuch as the Son is Son and the Father is Father, the Son is subordinate to the Father as His head.

Scripture is explicit in teaching that the Father is the head of the Son: “But I want you to know that the head of every man is Christ, the head of woman is man, and the head of Christ is God.” (1 Cor 11:3 NKJV) We see the Father’s headship over the Son again referred to in 1 Corinthians 15:24-28 “Then comes the end, when He delivers the kingdom to God the Father, when He puts an end to all rule and all authority and power. 25 For He must reign till He has put all enemies under His feet. 26 The last enemy that will be destroyed is death. 27 For “He has put all things under His feet.” But when He says “all things are put under Him,” it is evident that He who put all things under Him is excepted. 28 Now when all things are made subject to Him, then the Son Himself will also be subject to Him who put all things under Him, that God may be all in all.” (NKJV)

The Son’s subordination to the Father’s headship can also be seen apart from the incarnation entirely; God sends the Son, and the Son is sent; God creates through His Son, not His Son through Him; and throughout the Old Testament we read of Christ as the “Angel (that is, Messenger) of the LORD”, bringing messages from the Father to men, ministering to the Father’s will.

On this point, there is abundant testimony from the church fathers:

““I shall give you another testimony, my friends,” said I, “from the Scriptures, that God begat before all creatures a Beginning,403 [who was] a certain rational power [proceeding] from Himself, who is called by the Holy Spirit, now the Glory of the Lord, now the Son, again Wisdom, again an Angel, then God, and then Lord and Logos; and on another occasion He calls Himself Captain, when He appeared in human form to Joshua the son of Nave (Nun). For He can be called by all those names, since He ministers to the Father’s will, and since He was begotten of the Father by an act of will…” (Justin Martyr, Dialogue With Trypho, Chapter 61)

“XVI. “If any man does not understand The Lord rained from the Lord to be spoken of the Father and the Son, but says that the Father rained from Himself: let him be anathema. For the Lord the Son rained from the Lord the Father.”…

XVII. If any man says that the Lord and the Lord, the Father and the Son, are two Gods because of the aforesaid words: let him be anathema. For we do not make the Son the equal or peer of the Father, but understand the Son to be subject. For He did not come down to Sodom without the Father’s will, nor rain from Himself but from the Lord, to wit, by the Father’s authority; nor does He sit at the Father’s right hand by His own authority, but because He hears the Father saying, Sit on My right hand.

51. The foregoing and the following statements utterly remove any ground for suspecting that this definition asserts a diversity of different deities in the Lord and the Lord. No comparison is made because it was seen to be impious to say that there are two Gods: not that they refrain from making the Son equal and peer of the Father in order to deny that He is God. For, since he is anathema who denies that Christ is God, it is not on that score that it is profane to speak of two equal Gods. God is One on account of the true character of His natural essence and because from the Unborn God the Father, who is the one God, the Only-begotten God the Son is born, and draws His divine Being only from God; and since the essence of Him who is begotten is exactly similar to the essence of Him who begot Him, there must be one name for the exactly similar nature. That the Son is not on a level with the Father and is not equal to Him is chiefly shown in the fact that He was subjected to Him to render obedience, in that the Lord rained from the Lord and that the Father did not, as Photinus and Sabellius say, rain from Himself, as the Lord from the Lord; in that He then sat down at the right hand of God when it was told Him to seat Himself; in that He is sent, in that He receives, in that He submits in all things to the will of Him who sent Him. But the subordination of filial love is not a diminution of essence, nor does pious duty cause a degeneration of nature, since in spite of the fact that both the Unborn Father is God and the Only-begotten Son of God is God, God is nevertheless One, and the subjection and dignity of the Son are both taught in that by being called Son He is made subject to that name which because it implies that God is His Father is yet a name which denotes His nature. Having a name which belongs to Him whose Son He is, He is subject to the Father both in service and name; yet in such a way that the subordination of His name bears witness to the true character of His natural and exactly similar essence.” (Hilary of Poitiers, De Synodis; Therein quoting the Council of Sirmium Against Photinius)

We see then that in reference to headship, the Son, as Son, is subordinate to the Father in “the obedience of filial love”, and yet as we have said above, is equal to the Father in respect to His divinity.

Having then addressed the categories of nature and headship, we come to the third category of ‘causality’.

The Son is subordinate to the Father as His Cause. In having begotten the Son before the ages, the Father Himself is the Cause of the Son, as the Son has both His person and essence from the Father in eternal generation. This is closely related to the other two categories; because the Father is the Origin of the Son by eternal generation, the Son is both equal to the Father in respect to nature, as having the Father’s nature communicated to Him in eternal generation, and yet subordinate to the Father as His Head because the Father is truly ontologically His Father, and therefore the Cause of His being.

That the Father is the origin and cause of the Son is obvious from the doctrine of eternal generation, which as we have noted above, teaches that the Son was begotten of the Father before the ages (that is, before and outside of time, which as part of creation (Heb 1:2), was created through the Son). Begetting by definition indicates causality; as do the very names “Father” and “Son”. The Father is unbegotten, uncaused, and unoriginate, while the Son is begotten of the Father, and thus has the Father as His cause and origin.

We have express testimony in scripture that the Son is begotten of the Father, in that the Son is called “only-begotten”, as is mentioned above. John 5:26 also says “For just as the Father has life in Himself, even so He gave to the Son also to have life in Himself” (NASB). Here we clearly see the communication of the Father’s nature to the Son taught.

As in the two previous categories, there is much patristic support for this reading of scripture.

“II. “And if any one hearing the Son say, As the Father has life in Himself, so also has He given to the Son to have life in Himself John 5:26, shall say that He who has received life from the Father, and who also declares, I live by the Father , is the same as He who gave life: let him be anathema.

14. The person of the recipient and of the giver are distinguished so that the same should not be made one and sole. For since he is under anathema who has believed that, when recipient and giver are mentioned one solitary and unique person is implied, we may not suppose that the selfsame person who gave received from Himself. For He who lives and He through whom He lives are not identical, for one lives to Himself, the other declares that He lives through the Author of His life, and no one will declare that He who enjoys life and He through whom His life is caused are personally identical.” (Hilary of Poitier, De Synodis)

““Is not the meaning here of the word ὁμοούσιον that the Son is produced of the Father’s nature, the essence of the Son having no other origin, and that both, therefore, have one unvarying essence? As the Son’s essence has no other origin, we may rightly believe that both are of one essence, since the Son could be born with no substance but that derived from the Father’s nature which was its source.”” (Hilary of Poitiers, De Synodis)

 

“But now, whatever He is, He is not of Himself, because He is not unborn; but He is of the Father, because He is begotten, whether as being the Word, whether as being the Power, or as being the Wisdom, or as being the Light, or as being the Son; and whatever of these He is, in that He is not from any other source, as we have already said before, than from the Father, owing His origin to His Father, He could not make a disagreement in the divinity by the number of two Gods, since He gathered His beginning by being born of Him who is one God.” (Novatian, A Treatise Concerning the Trinity, Chapter XXXI.)

““11. And thus there appeared another beside Himself. But when I say another, I do not mean that there are two Gods, but that it is only as light of light, or as water from a fountain, or as a ray from the sun. For there is but one power, which is from the All; and the Father is the All, from whom comes this Power, the Word. And this is the mind which came forth into the world, and was manifested as the Son of God. All things, then, are by Him, and He alone is of the Father. Who then adduces a multitude of gods brought in, time after time? For all are shut up, however unwillingly, to admit this fact, that the All runs up into one. If, then, all things run up into one, even according to Valentinus, and Marcion, and Cerinthus, and all their fooleries, they are also reduced, however unwillingly, to this position, that they must acknowledge that the One is the cause of all things. Thus, then, these too, though they wish it not, fall in with the truth, and admit that one God made all things according to His good pleasure. And He gave the law and the prophets; and in giving them, He made them speak by the Holy Ghost, in order that, being gifted with the inspiration of the Father’s power, they might declare the Father’s counsel and will.”” (Hippolytus of Rome, Against the Heresy of One Noetus)

“And now I shall again recite the words which I have spoken in proof of this point. When Scripture says, ‘The Lord rained fire from the Lord out of heaven,’ the prophetic word indicates that there were two in number: One upon the earth, who, it says, descended to behold the cry of Sodom; Another in heaven, who also is Lord of the Lord on earth, as He is Father and God; the cause of His power and of His being Lord and God.” (Justin Martyr, Dialogue With Trypho, Chapter 129)

“For the Word, being Son of the One God, is referred to Him of whom also He is; so that Father and Son are two, yet the Monad of the Godhead is indivisible and inseparable. And thus too we preserve One Beginning of Godhead and not two Beginnings, whence there is strictly a Monarchy. And of this very Beginning the Word is by nature Son, not as if another beginning, subsisting by Himself, nor having come into being externally to that Beginning, lest from that diversity a Dyarchy and Polyarchy should ensue; but of the one Beginning He is own Son, own Wisdom, own Word, existing from It.” (Athanasius, Against the Arians, Discourse 4)

“We believe then In the Only-Begotten Son of God, Who Was Begotten of the Father Very God. For the True God begets not a false god, as we have said, nor did He deliberate and afterwards beget ; but He begot eternally, and much more swiftly than our words or thoughts: for we speaking in time, consume time; but in the case of the Divine Power, the generation is timeless. And as I have often said, He did not bring forth the Son from non-existence into being, nor take the non-existent into sonship : but the Father, being Eternal, eternally and ineffably begot One Only Son, who has no brother. Nor are there two first principles; but the Father is the head of the Son 1 Corinthians 11:3; the beginning is One… Suffer none to speak of a beginning of the Son in time, but as a timeless Beginning acknowledge the Father. For the Father is the Beginning of the Son, timeless, incomprehensible, without beginning. The fountain of the river of righteousness, even of the Only-begotten, is the Father, who begot Him as Himself only knows.” (Cyril of Jerusalem, Catechetical Lecture 11)

So we see the testimony of the orthodox fathers of the ante-nicene and nicene eras is that the Son has the Father as His origin and cause, in agreement with the teaching of scripture.

We see then, that the scriptures teach the Son to be equal with the Father in respect to His nature, as having the same divine nature, yet they also teach that the Son is subordinate to the Father as His Head and Cause. It is neither sufficient nor helpful to speak of the relationship of the Son to the Father simply as one either of ‘equality’ or ‘subordination’ without further distinction.

For if we say only that the Son is subordinate we may be taken to deny the Son’s equality with the Father in respect to His divinity, which is to blaspheme the Son greatly; yet if we deny the Son’s subordination to the Father as to His Head and His Origin by only calling Him “equal” without qualification, we will have blasphemously declared the Son to be a second God, by making there out to be two equal heads over all, and two first causes and unoriginate origins. But there are not two gods, but “yet for us there is one God, the Father, of whom are all things, and we for Him; and one Lord Jesus Christ, through whom are all things, and through whom we live.” (1 Cor 8:6 NKJV) There is one alone Who is Head of all, yet Himself without a head; one Who is alone unbegotten and without origin, the one First Cause; the Father of one only-begotten Son, Who together with the Father is head over all creation, the Word of Whom scripture says “All things were made through Him, and without Him nothing was made that was made. ” (John 1:3 NKJV).

Let us then seek to be careful in distinguishing between these various categories, lest we fall into error one way or another by making broad and unqualified statements.

 

I believe in one God, the Father Almighty

Scriptural Proof:

“There is one body and one Spirit, just as also you were called in one hope of your calling; 5 one Lord, one faith, one baptism, 6 one God and Father of all who is over all and through all and in all.” Ephesians 4:4-5 NAS

“This is eternal life, that they may know You, the only true God, and Jesus Christ whom You have sent.” John 17:3 NAS

“yet for us there is but one God, the Father, from whom are all things and we exist for Him; and one Lord, Jesus Christ, by whom are all things, and we exist through Him.” 1 Corinthians 8:6 NAS

Ancient Patristic Witness:

Clement of Rome:

“Why are there strifes, and tumults, and divisions, and schisms, and wars  among you? Have we not [all] one God and one Christ? Is there not one Spirit of grace poured out upon us?” 1 Clement, Chapter XLVI.

Ignatius of Antioch:

“On this account also they were persecuted, being inspired by His grace to fully convince the unbelieving that there is one God, who has manifested Himself by Jesus Christ His Son, who is His eternal Word, not proceeding forth from silence, and who in all things pleased Him that sent Him.” Epistle to the Magnesians (shorter version), Chapter VIII.

“If any one confesses Christ Jesus the Lord, but denies the God of the law and of the prophets, saying that the Father of Christ is not the Maker of heaven and earth, he has not continued in the truth any more than his father the devil, and is a disciple of Simon Magus, not of the Holy Spirit. If any one says there is one God, and also confesses Christ Jesus, but thinks the Lord to be a mere man, and not the only-begotten God, and Wisdom, and the Word of God, and deems Him to consist merely of a soul and body, such an one is a serpent, that preaches deceit and error for the destruction of men.” Epistle to the Philadelphians (longer version), Chapter VI.

“The prophets also, when they speak as in the person of God, [saying,] “I am God, the first [of beings], and I am also the last, and besides Me there is no God,” concerning the Father of the universe, do also speak of our Lord Jesus Christ.” Epistle to the Antiochians, Chapter III.

“The Evangelists, too, when they declared that the one Father was “the only true God,” did not omit what concerned our Lord, but wrote: “In the beginning was the Word, and the Word was with God, and the Word was God.” Epistle to the Antiochians, Chapter IV.

“For if there is one God of the universe, the Father of Christ, “of whom are all things;” and one Lord Jesus Christ, our [Lord], “by whom are all things;” and also one Holy Spirit, who wrought in Moses, and in the prophets and apostles; and also one baptism, which is administered that we should have fellowship with the death of the Lord; and also one elect Church; there ought likewise to be but one faith in respect to Christ. For “there is one Lord, one faith, one baptism; one God and Father of all, who is through all, and in all.”” Epistle to the Philippians, Chapter I.

“There is then one God and Father, and not two or three; One who is; and there is no other besides Him, the only true [God]. For “the Lord thy God,” saith [the Scripture], “is one Lord.” And again, “Hath not one God created us? Have we not all one Father? And there is also one Son, God the Word. For “the only-begotten Son,” saith [the Scripture], “who is in the bosom of the Father.”  And again, “One Lord Jesus Christ.” And in another place, “What is His name, or what His Son’s name, that we may know?” And there is also one Paraclete. For “there is also,” saith [the Scripture], “one Spirit,” since “we have been called in one hope of our calling.”” Epistle to the Philippians, Chapter II.

“Ignatius answered, “Thou art in error when thou callest the dæmons of the nations gods. For there is but one God, who made heaven, and earth, and the sea, and all that are in them; and one Jesus Christ, the only-begotten Son of God, whose kingdom may I enjoy.”” Ignatius before Trajan, at his martyrdom. From the Martyrdom of Ignatius, Chapter II.

Irenaeus of Lyons:

“And others of them, with great craftiness, adapted such parts of Scripture to their own figments, lead away captive from the truth those who do not retain a stedfast faith in one God, the Father Almighty, and in one Lord Jesus Christ, the Son of God.” Against Heresies, Book I. Chapter III. 6.

“The fallacy, then, of this exposition is manifest. For when John, proclaiming one God, the Almighty, and one Jesus Christ, the Only-begotten, by whom all things were made, declares that this was the Son of God, this the Only-begotten, this the Former of all things, this the true Light who enlighteneth every man, this the Creator of the world, this He that came to His own, this He that became flesh and dwelt among us,–these men, by a plausible kind of exposition, perverting these statements, maintain that there was another Monogenes, according to production, whom they also style Arche.” Against Heresies, Book I. Chapter IX. 2.

“But if the Word of the Father who descended is the same also that ascended, He, namely, the Only-begotten Son of the only God, who, according to the good pleasure of the Father, became flesh for the sake of men, the apostle certainly does not speak regarding any other, or concerning any Ogdoad, but respecting our Lord Jesus Christ.” Against Heresies, Book I. Cahpter IX. 3.

“The Church, though dispersed through our the whole world, even to the ends of the earth, has received from the apostles and their disciples this faith: [She believes] in one God, the Father Almighty, Maker of heaven, and earth, and the sea, and all things that are in them; and in one Christ Jesus, the Son of God, who became incarnate for our salvation; and in the Holy Spirit, who proclaimed through the prophets the dispensations of God” Against Heresies, Book I. Chapter X. 1.

“The rule of truth which we hold, is, that there is one God Almighty, who made all things by His Word, and fashioned and formed, out of that which had no existence, all things which exist. Thus saith the Scripture, to that effect: “By the Word of the Lord were the heavens established, and all the might of them, by the spirit of His mouth.” And again, “All things were made by Him, and without Him was nothing made.”” Against Heresies, Book I. Chapter XXII. 1.

“It is proper, then, that I should begin with the first and most important head, that is, God the Creator, who made the heaven and the earth, and all things that are therein (whom these men blasphemously style the fruit of a defect), and to demonstrate that there is nothing either above Him or after Him; nor that, influenced by any one, but of His own free will, He created all things, since He is the only God, the only Lord, the only Creator, the only Father, alone containing all things, and Himself commanding all things into existence.” Against Heresies, Book II. Chapter I. 1.

“Now, that this God is the Father of our Lord Jesus Christ, Paul the apostle also has declared, [saying,] “There is one God, the Father, who is above all, and through all things, and in us all.” I have indeed proved already that there is only one God; but I shall further demonstrate this from the apostles themselves, and from the discourses of the Lord. For what sort of conduct would it be, were we to forsake the utterances of the prophets, of the Lord, and of the apostles, that we might give heed to these persons, who speak not a word of sense?” Against Heresies, Book II. Chapter II. 5.

“That God is the Creator of the world is accepted even by those very persons who in many ways speak against Him, and yet acknowledge Him, styling Him the Creator, and an angel, not to mention that all the Scriptures call out [to the same effect], and the Lord teaches us of this Father who is in heaven, and no other, as I shall show in the sequel of this work. For the present, however, that proof which is derived from those who allege doctrines opposite to ours, is of itself sufficient,–all men, in fact, consenting to this truth: the ancients on their part preserving with special care, from the tradition of the first-formed man, this persuasion, while they celebrate the praises of one God, the Maker of heaven and earth; others, again, after them, being reminded of this fact by the prophets of God, while the very heathen learned it from creation itself. For even creation reveals Him who formed it, and the very work made suggests Him who made it, and the world manifests Him who ordered it. The Universal Church, moreover, through the whole world, has received this tradition from the apostles.” Against Heresies, Book II. Chapter IX, 1.

“But there is one only God, the Creator—He who is above every Principality, and Power, and Dominion, and Virtue: He is Father, He is God, He the Founder, He the Maker, He the Creator, who made those things by Himself, that is, through His Word and His Wisdom— heaven and earth, and the seas, and all things that are in them: He is just; He is good; He it is who formed man, who planted paradise, who made the world, who gave rise to the flood, who saved Noah; He is the God of Abraham, and the God of Isaac, and the God of Jacob, the God of the living: He it is whom the law proclaims, whom the prophets preach, whom Christ reveals, whom the apostles make known to us, and in whom the Church believes. He is the Father of our Lord Jesus Christ: through His Word, who is His Son, through Him He is revealed and manifested to all to whom He is revealed; for those [only] know Him to whom the Son has revealed Him. But the Son, eternally coexisting with the Father, from of old, yea, from the beginning, always reveals the Father to Angels, Archangels, Powers, Virtues, and all to whom He wills that God should be revealed.” Against Heresies, Book II. Chapter XXX. 9.

“Now, that the preaching of the apostles, the authoritative teaching of the Lord, the announcements of the prophets, the dictated utterances of the apostles, and the ministration of the law–all of which  praise one and the same Being, the God and Father of all, and not many diverse beings, nor one deriving his substance from different gods or powers, but [declare] that all things [were formed] by one and the same Father (who nevertheless adapts [His works] to the natures and tendencies of the materials dealt with), things visible and invisible, and, in short, all things that have been made [were created] neither by angels, nor by any other power, but by God alone, the Father–are all in harmony with our statements, has, I think, been sufficiently proved, while by these weighty arguments it has been shown that there is but one God, the Maker of all things.” Against Heresies, Book II. Chapter XXXV. 4.

“These have all declared to us that there is one God, Creator of heaven and earth, announced by the law and the prophets; and one Christ the Son of God. If any one do not agree to these truths, he despises the companions of the Lord; nay more, he despises Christ Himself the Lord; yea, he despises the Father also, and stands self-condemned, resisting and opposing his own salvation, as is the case with all heretics.” Against Heresies, Book III. Chapter I. 2.

“In the time of this Clement, no small dissension having occurred among the brethren at Corinth, the Church in Rome despatched a most powerful letter to the Corinthians, exhorting them to peace, renewing their faith, and declaring the tradition which it had lately received from the apostles, proclaiming the one God, omnipotent, the Maker of heaven and earth, the Creator of man, who brought on the deluge, and called Abraham, who led the people from the land of Egypt, spake with Moses, set forth the law, sent the prophets, and who has prepared fire for the devil and his angels. From this document, whosoever chooses to do so, may learn that He, the Father of our Lord Jesus Christ, was preached by the Churches, and may also understand the apostolical tradition of the Church, since this Epistle is of older date than these men who are now propagating falsehood, and who conjure into existence another god beyond the Creator and the Maker of all existing things.” Against Heresies, Book III. Chapter III. 3.

“To which course many nations of those barbarians who believe in Christ do assent, having salvation written in their hearts by the Spirit, without paper or ink, and, carefully preserving the ancient tradition, believing in one God, the Creator of heaven and earth, and all things therein, by means of Christ Jesus, the Son of God; who, because of His surpassing love towards His creation, condescended to be born of the virgin, He Himself uniting man through Himself to God, and having suffered under Pontius Pilate, and rising again, and having been received up in splendour, shall come in glory, the Saviour of those who are saved, and the Judge of those who are judged, and sending into eternal fire those who transform the truth, and despise His Father and His advent.” Against Heresies, Book III. Chapter IV. 2.

“Since, therefore, this is sure and stedfast, that no other God or Lord was announced by the Spirit, except Him who, as God, rules over all, together with His Word, and those who receive the Spirit of adoption, [3805] that is, those who believe in the one and true God, and in Jesus Christ the Son of God; and likewise that the apostles did of themselves term no one else as God, or name [no other] as Lord; and, what is much more important, [since it is true] that our Lord [acted likewise], who did also command us to confess no one as Father, except Him who is in the heavens, who is the one God and the one Father;–those things are clearly shown to be false which these deceivers and most perverse sophists advance” Against Heresies, Book IV, Chapter I. 1.

“And therefore it is right first of all to believe that there is One God, the Father, who made and fashioned all things, and made what was not that it should be, and who, containing all things, alone is uncontained.” The Demonstration of the Apostolic Preaching (TDAP)

“Thus then there is shown forth One God, the Father, not made, invisible, creator of all things; above whom there is no other God, and after whom there is no other God. And, since God is rational, therefore by (the) Word He created the things that were made; and God is Spirit, and by (the) Spirit He adorned all things…” TDAP

“This then is the order of the rule of our faith, and the foundation of the building, and the stability of our conversation: God, the Father, not made, not material, invisible; one God, the creator of all things: this is the first point of our faith. The second point is: The Word of God, Son of God, Christ Jesus our Lord, who was manifested to the prophets according to the form of their prophesying and according to the method of the dispensation of the Father: through whom all things were made; who also at the end of the times, to complete and gather up all things, was made man among men, visible and tangible, in order to abolish death and show forth life and produce a community of union between God and man. And the third point is: The Holy Spirit, through whom the prophets prophesied, and the fathers learned the things of God, and the righteous were led forth into the way of righteousness; and who in the end of the times was poured out in a new way upon mankind in all the earth, renewing man unto God.” TDAP

Theophilus of Antioch:

“But God at least, the Father and Creator of the universe, did not abandon mankind, but gave a law, and sent holy prophets to declare and teach the race of men, that each one of us might awake and understand that there is one God.” Theophilus to Autolycus, Book II. Chapter XXXIV.

Athenagoras of Athens:

“But, since our doctrine acknowledges one God, the Maker of this universe, who is Himself uncreated (for that which is does not come to be, but that which is not) but has made all things by the Logos which is from Him, we are treated unreasonably in both respects, in that we are both defamed and persecuted.” A Plea For the Christians, Chapter IV.

“That we are not atheists, therefore, seeing that we acknowledge one God, uncreated, eternal, invisible, impassible, incomprehensible, illimitable, who is apprehended by the understanding only and the reason, who is encompassed by light, and beauty, and spirit, and power ineffable, by whom the universe has been created through His Logos, and set in order, and is kept in being—I have sufficiently demonstrated. [I say “His Logos”], for we acknowledge also a Son of God.” A Plea For the Christians, Chapter X.

Clement of Alexandria:

““Now the just shall live by faith,” which is according to the covenant and the commandments; since these, which are two in name and time, given in accordance with the [divine] economy—being in power one—the old and the new, are dispensed through the Son by one God.” Stromata Book 2, Chapter VI

“Wherefore also the apostle designates as “the express image (χαρακτῆρα) of the glory of the Father” the Son, who taught the truth respecting God, and expressed the fact that the Almighty is the one and only God and Father, “whom no man knoweth but the Son, and he to whom the Son shall reveal Him. That God is one is intimated by those “who seek the face of the God of Jacob;” whom being the only God, our Saviour and God characterizes as the Good Father.” Stromata, Book 7, Chapter X.

“And that the men of highest repute among the Greeks knew God, not by positive knowledge, but by indirect expression,2407 Peter says in the Preaching: “Know then that there is one God, who made the beginning of all things, and holds the power of the end; and is the Invisible, who sees all things; incapable of being contained, who contains all things; needing nothing, whom all things need, and by whom they are; incomprehensible, everlasting, unmade, who made all things by the ‘Word of His power,’ that is, according to the gnostic scripture, His Son.”” Stromata Book 6, Chapter V

Tertullian of Carthage:

“The object of our worship is the One God, He who by His commanding word, His arranging wisdom, His mighty power, brought forth from nothing this entire mass of our world, with all its array of elements, bodies, spirits, for the glory of His majesty; whence also the Greeks have bestowed on it the name of Κόσμος. The eye cannot see Him, though He is (spiritually) visible.” Apology, Chapter XVII.

“We, however, as we indeed always have done (and more especially since we have been better instructed by the Paraclete, who leads men indeed into all truth), believe that there is one only God, but under the following dispensation, or οἰκονομία , as it is called, that this one only God has also a Son, His Word, who proceeded from Himself, by whom all things were made, and without whom nothing was made. Him we believe to have been sent by the Father into the Virgin, and to have been born of her—being both Man and God, the Son of Man and the Son of God, and to have been called by the name of Jesus Christ; we believe Him to have suffered, died, and been buried, according to the Scriptures, and, after He had been raised again by the Father and taken back to heaven, to be sitting at the right hand of the Father, and that He will come to judge the quick and the dead; who sent also from heaven from the Father, according to His own promise, the Holy Ghost, the Paraclete, the sanctifier of the faith of those who believe in the Father, and in the Son, and in the Holy Ghost.” Against Praxeas, Chapter II.

“Hence, therefore, their error becomes manifest; for, being ignorant that the entire order of the divine administration has from the very first had its course through the agency of the Son, they believe that the Father Himself was actually seen, and held converse with men, and worked, and was athirst, and suffered hunger (in spite of the prophet who says: “The everlasting God, the Lord, the Creator of the ends of the earth, shall never thirst at all, nor be hungry;” much more, shall neither die at any time, nor be buried!), and therefore that it was uniformly one God, even the Father, who at all times did Himself the things which were really done by Him through the agency of the Son” Against Praxeas, Chapter XVI.

“When, therefore, He attested His own unity, the Father took care of the Son’s interests, that Christ should not be supposed to have come from another God, but from Him who had already said, “I am God and there is none other beside me,” who shows us that He is the only God, but in company with His Son, with whom “He stretcheth out the heavens alone.”” Against Praxeas, Chapter XVIII.

“But, (this doctrine of yours bears a likeness) to the Jewish faith, of which this is the substance—so to believe in One God as to refuse to reckon the Son besides Him, and after the Son the Spirit.” Against Praxeas, Chapter XXXI.

“Him had the Law the People shown to be One God, whose mighty voice to Moses spake Upon the mount. Him this His Virtue, too, His Wisdom, Glory, Word, and Son, this Light 35 Begotten from the Light immense, proclaims Through the seers’ voices, to be One…” Five Books Against Marcion; Of Marcion’s Antithesis (Authorship Uncertain –found as an Appendix to Tertullian’s Writings)

Origen:

“The particular points clearly delivered in the teaching of the apostles are as follow:– First, That there is one God, who created and arranged all things, and who, when nothing existed, called all things into being–God from the first creation and foundation of the world–the God of all just men, of Adam, Abel, Seth, Enos, Enoch, Noe, Sere, Abraham, Isaac, Jacob, the twelve patriarchs, Moses, and the prophets; and that this God in the last days, as He had announced beforehand by His prophets, sent our Lord Jesus Christ to call in the first place Israel to Himself, and in the second place the Gentiles, after the unfaithfulness of the people of Israel. This just and good God, the Father of our Lord Jesus Christ, Himself gave the law and the prophets, and the Gospels, being also the God of the apostles and of the Old and New Testaments.” De Principiis, Preface 4.

“But whether Orpheus, Parmenides, Empedocles, or even Homer himself, and Hesiod, are the persons whom he means by “inspired poets,” let any one show how those who follow their guidance walk in a better way, or lead a more excellent life, than those who, being taught in the school of Jesus Christ, have rejected all images and statues, and even all Jewish superstition, that they may look upward through the Word of God to the one God, who is the Father of the Word” Origen Against Celsus, Book VII. Chapter XLI.

“Accordingly, we worship with all our power the one God, and His only Son, the Word and the Image of God, by prayers and supplications; and we offer our petitions to the God of the universe through His only-begotten Son.” Origen Against Celsus, Book VIII. Chapter XIII.

Hippolytus of Rome:

“For it is right, in the first place, to expound the truth that the Father is one God, “of whom is every family,” “by whom are all things, of whom are all things, and we in Him.”” Against the Heresy of One Noetus, 3.

“If, therefore, all things are put under Him with the exception of Him who put them under Him, He is Lord of all, and the Father is Lord of Him, that in all there might be manifested one God, to whom all things are made subject together with Christ, to whom the Father hath made all things subject, with the exception of Himself. And this, indeed, is said by Christ Himself, as when in the Gospel He confessed Him to be His Father and His God. For He speaks thus: “I go to my Father and your Father, and to my God and your God.”” Against the Heresy of One Noetus, 6.

Novatian:

“Thus God the Father, the Founder and Creator of all things, who only knows no beginning, invisible, infinite, immortal, eternal, is one God; to whose greatness, or majesty, or power, I would not say nothing can be preferred, but nothing can be compared; of whom, when He willed it, the Son, the Word, was born, who is not received in the sound of the stricken air, or in the tone of voice forced from the lungs, but is acknowledged in the substance of the power put forth by God, the mysteries of whose sacred and divine nativity neither an apostle has learnt, nor prophet has discovered, nor angel has known, nor creature has apprehended.” A Treatise of Novatian Concerning the Trinity, Chapter XXXI.

“Assuredly God proceeding from God, causing a person second to the Father as being the Son, but not taking from the Father that characteristic that He is one God.” A Treatise of Novatian Concerning the Trinity, Chapter XXXI.

“But now, whatever He is, He is not of Himself, because He is not unborn; but He is of the Father, because He is begotten, whether as being the Word, whether as being the Power, or as being the Wisdom, or as being the Light, or as being the Son; and whatever of these He is, in that He is not from any other source, as we have already said before, than from the Father, owing His origin to His Father, He could not make a disagreement in the divinity by the number of two Gods, since He gathered His beginning by being born of Him who is one God.” A Treatise of Novatian Concerning the Trinity, Chapter XXXI.

“Thus making Himself obedient to His Father in all things, although He also is God, yet He shows the one God the Father by His obedience, from whom also He drew His beginning.” A Treatise of Novatian Concerning the Trinity, Chapter XXXI.

“The true and eternal Father is manifested as the one God, from whom alone this power of divinity is sent forth, and also given and directed upon the Son, and is again returned by the communion of substance to the Father. God indeed is shown as the Son, to whom the divinity is beheld to be given and extended. And still, nevertheless, the Father is proved to be one God; while by degrees in reciprocal transfer that majesty and divinity are again returned and reflected as sent by the Son Himself to the Father, who had given them; so that reasonably God the Father is God of all, and the source also of His Son Himself whom He begot as Lord.” A Treatise of Novatian Concerning the Trinity, Chapter XXXI.

Gregory Thaumaturgus:

“There is one God, the Father of the living Word, who is His subsistent Wisdom and Power and Eternal Image: perfect Begetter of the perfect Begotten, Father of the only-begotten Son.” A Declaration of Faith

Lactantius:

“I have, as I think, sufficiently taught by arguments, and confirmed by witnesses, that which is sufficiently plain by itself, that there is one only King of the universe, one Father, one God.” The Divine Institutes, Chapter VII.

Apostolic Constitutions:

“But we, who are the children of God and the sons of peace, do preach the holy and right word of piety, and declare one only God, the Lord of the law and of the prophets, the Maker of the world, the Father of Christ; not a being that caused Himself, or begat Himself, as they suppose, but eternal, and without original, and inhabiting light inaccessible; not two or three, or manifold, but eternally one only; not a being that cannot be known or spoken of, but who was preached by the law and the prophets; the Almighty, the Supreme Governor of all things, the All-powerful Being; the God and Father of the Only-begotten, and of the First-born of the whole creation; one God, the Father of one Son” Apostolic Constitutions, Book VI. Section III.

“…we declare unto you, that there is only one God Almighty, besides whom there is no other, and that you must worship and adore Him alone, through Jesus Christ our Lord, in the most holy Spirit;” Apostolic Constitutions, Book VI. Section III.

Athanasius:

“Nay I would add, that they were said even in anticipation of the folly of these Christ-opposers, that they might know, that whatsoever god they devise external to the Father’s Essence, he is not True God, nor Image and Son of the Only and First.” Against the Arians, Discourse III.

“He it is who through His Word made all things small and great, and we may not divide the creation, and says this is the Father’s, and this the Son’s, but they are of one God, who uses His proper Word as a Hand, and in Him does all things. This God Himself shews us, when He says, ‘All these things hath My Hand made;’ while Paul taught us as he had learned, that ‘There is one God, from whom all things; and one Lord Jesus Christ, through whom all things.” Defense of the Nicene Definition, Chapter III.

”But if this is not to be seen, but while the creatures are many, the Word is one, any one will collect from this, that the Son differs from all, and is not on a level with the creatures, but proper to the Father. Hence there are not many Words, but one only Word of the one Father, and one Image of the one God.” Against the Arians, Discourse II.

“For where at all have they found in divine Scripture, or from whom have they heard, that there is another Word and another Wisdom besides this Son, that they should frame to themselves such a doctrine? True, indeed, it is written, ‘Are not My words like fire, and like a hammer that breaketh the rock in pieces?’ and in the Proverbs, ‘I will make known My words unto you;’ but these are precepts and commands, which God has spoken to the saints through His proper and only true Word, concerning which the Psalmist said, ‘I have refrained my feet from every evil way, that I may keep Thy words.’ Such words accordingly the Saviour signifies to be distinct from Himself, when He says in His own person, ‘The words which I have spoken unto you.’ For certainly such words are not offsprings or sons, nor are there so many words that frame the world, nor so many images of the One God, nor so many who have become men for us, nor as if from many such there were one who has become flesh, as John says; but as being the only Word of God was He preached by John, ‘The Word was made flesh,’ and ‘all things were made by Him.’” Against the Arians, Discourse II.

“Accordingly when the Father is called the only God, and we read that there is one God, and ‘I am,’ and ‘beside Me there is no God,’ and ‘I the first and I the last,’ this has a fit meaning. For God is One and Only and First; but this is not said to the denial of the Son, perish the thought; for He is in that One, and First and Only, as being of that One and Only and First the Only Word and Wisdom and Radiance. And He too is the First, as the Fulness of the Godhead of the First and Only, being whole and full God.” Against the Arians, Discourse III.
“For, as the illustration shows, we do not introduce three Origins or three Fathers, as the followers of Marcion and Manichæus; since we have not suggested the image of three suns, but sun and radiance. And one is the light from the sun in the radiance; and so we know of but one origin; and the All-framing Word we profess to have no other manner of godhead, than that of the Only God, because He is born from Him.” Against the Arians, Discourse III.

“For there is but one form of Godhead, which is also in the Word; and one God, the Father, existing by Himself according as He is above all, and appearing in the Son according as He pervades all things, and in the Spirit according as in Him He acts in all things through the Word.” Against the Arians, Discourse III.

“For there is One God, and not many, and One is His Word, and not many; for the Word is God, and He alone has the Form of the Father.” Against the Arians, Discourse III.

“For the Word, being Son of the One God, is referred to Him of whom also He is; so that Father and Son are two, yet the Monad of the Godhead is indivisible and inseparable. And thus too we preserve One Beginning of Godhead and not two Beginnings, whence there is strictly a Monarchy” Against the Arians, Discourse IV.

“For the one God makes and creates; but Him He begets from Himself, Word or Wisdom.” Against the Arians, Discourse IV.

“The Triad, then, although the Word took a body from Mary, is a Triad, being inaccessible to addition or diminution; but it is always perfect, and in the Triad one Godhead is recognised, and so in the Church one God is preached, the Father of the Word.” To Epictetus

“The Father does all things, by the Word, and in the Holy Spirit: And so the Unity of the Holy Trinity is preserved: And so one God is preached in the Church; even He who is over all, and through all, and in all: Over all, as he is the Father and Original and Fountain of all; Through all by His Word; and in all, by His Holy Spirit.” Epistle Ad Serapion 1.

Cyril of Jerusalem:

“Further, do thou neither separate the Son from the Father, nor by making a con- fusion believe in a Son-Fatherhood; but believe that of One God there is One Only-begotten Son, who is before all ages God the Word; not the uttered word diffused into the air, nor to be likened to impersonal words; but the Word the Son, Maker of all who partake of reason, the Word who heareth the Father, and Himself speaketh.” On the Ten Points of Doctrine (Lecture IV)

“For there is One God, the Father of Christ; and One Lord Jesus Christ, the Only-begotten Son of the Only God; and One Holy Ghost…” On the Ten Points of Doctrine (Lecture IV)

“Of God as the sole Principle we have said enough to you yesterday:  by “enough” I mean, not what is worthy of the subject, (for to reach that is utterly impossible to mortal nature), but as much as was granted to our infirmity.  I traversed also the bye-paths of the manifold error of the godless heretics:  but now let us shake off their foul and soul-poisoning doctrine, and remembering what relates to them, not to our own hurt, but to our greater detestation of them, let us come back to ourselves, and receive the saving doctrines of the true Faith, connecting the dignity of Fatherhood with that of the Unity, and believing In One God the Father:  for we must not only believe in one God; but this also let us devoutly receive, that He is the Father of the Only-begotten, our Lord Jesus Christ.” The Father (Lecture VII)

“For thus shall we raise our thoughts higher than the Jews, who admit indeed by their doctrines that there is One God, (for what if they often denied even this by their idolatries?); but that He is also the Father of our Lord Jesus Christ, they admit not; being of a contrary mind to their own Prophets, who in the Divine Scriptures affirm, The Lord said unto me, Thou art My Son, this day have I begotten thee.” The Father (Lecture VII)

“But let us adopt the godly doctrine of our Faith, worshipping one God the Father of the Christ…” The Father (Lecture VII)

“For if a Father, He is certainly the Father of a Son; and if a Son, certainly the Son of a Father.  Lest therefore from our speaking thus, In One God, the Father Almighty, Maker of Heaven and Earth, and of All Things Visible and Invisible, and from our then adding this also, And in One Lord Jesus Christ, any one should irreverently suppose that the Only-begotten is second in rank to heaven and earth,—for this reason before naming them we named God the Father, that in thinking of the Father we might at the same time think also of the Son:  for between the Son and the Father no being whatever comes.” The Father (Lecture VII)

“But worship thou One God the Almighty, the Father of our Lord Jesus Christ.” Almighty (Lecture VIII)

“Be not thou carried away with the Jews when they craftily say, There is one God alone; but with the knowledge that God is One, know that there is also an Only-begotten Son of God.” On the Clause, And In One Lord Jesus Christ, with a Reading From the First Epistle to the Corinthians (Lecture X)

“There is One God, the Father, Lord of the Old and of the New Testament:  and One Lord, Jesus Christ, who was prophesied of in the Old Testament, and came in the New; and One Holy Ghost, who through the Prophets preached of Christ, and when Christ was come, descended, and manifested Him.” On the Article, And In One Holy Ghost, the Comforter, Which Spake In the Prophets (Lecture XVI)
“The Father through the Son, with the Holy Ghost, is the giver of all grace; the gifts of the Father are none other than those of the Son, and those of the Holy Ghost; for there is one Salvation, one Power, one Faith; One God, the Father; One Lord, His only-begotten Son; One Holy Ghost, the Comforter. ” On the Article, And In One Holy Ghost, the Comforter, Which Spake In the Prophets (Lecture XVI)
