God is one

But the Christian verity has distinctly declared this principle, “God is not, if He is not one;” because we more properly believe that that has no existence which is not as it ought to be. In order, however, that you may know that God is one, ask what God is, and you will find Him to be not otherwise than one. So far as a human being can form a definition of God, I adduce one which the conscience of all men will also acknowledge,—that God is the great Supreme existing in eternity, unbegotten, unmade without beginning, without end.

…Whatever other god, then, you may introduce, you will at least be unable to maintain his divinity under any other guise, than by ascribing to him too the property of Godhead—both eternity and supremacy over all. How, therefore, can two great Supremes co-exist, when this is the attribute of the Supreme Being, to have no equal,—an attribute which belongs to One alone, and can by no means exist in two?

The Greeks had vague references to the Trinity

For I pass over Plato; he plainly, in the Epistle to Erastus and Coriscus, is seen to exhibit the Father and Son somehow or other from the Hebrew Scriptures, exhorting in these words: “In invoking by oath, with not illiterate gravity, and with culture, the sister of gravity, God the author of all, and invoking Him by oath as the Lord, the Father of the Leader, and author; whom if ye study with a truly philosophical spirit, ye shall know.” And the address in the Timœus calls the creator, Father, speaking thus: “Ye gods of gods, of whom I am Father; and the Creator of your works.” So that when he says, “Around the king of all, all things are, and because of Him are all things; and he [or that] is the cause of all good things; and around the second are the things second in order; and around the third, the third,” I understand nothing else than the Holy Trinity to be meant; for the third is the Holy Spirit, and the Son is the second, by whom all things were made according to the will of the Father.

A prayer to Christ the Instructor

Be gracious, O Instructor, to us Thy children, Father, Charioteer of Israel, Son and Father, both in One, O Lord. Grant to us who obey Thy precepts, that we may perfect the likeness of the image, and with all our power know Him who is the good God and not a harsh judge. And do Thou Thyself cause that all of us who have our conversation in Thy peace, who have been translated into Thy commonwealth, having sailed tranquilly over the billows of sin, may be wafted in calm by Thy Holy Spirit, by the ineffable wisdom, by night and day to the perfect day; and giving thanks may praise, and praising thank the Alone Father and Son, Son and Father, the Son, Instructor and Teacher, with the Holy Spirit, all in One, in whom is all, for whom all is One, for whom is eternity, whose members we all are, whose glory the æons are; for the All-good, All-lovely, All-wise, All-just One. To whom be glory both now and for ever. Amen.

Father, Son and Holy Spirit are one essence

For, as we acknowledge a God, and a Son his Logos, and a Holy Spirit, united in essence,—the Father, the Son, the Spirit, because the Son is the Intelligence, Reason, Wisdom of the Father, and the Spirit an effluence, as light from fire; so also do we apprehend the existence of other powers, which exercise dominion about matter, and by means of it, and one in particular, which is hostile to God:

God is immaterial spirit

But grant that they acknowledge the same. What then? Because the multitude, who cannot distinguish between matter and God, or see how great is the interval which lies between them, pray to idols made of matter, are we therefore, who do distinguish and separate the uncreated and the created, that which is and that which is not, that which is apprehended by the understanding and that which is perceived by the senses, and who give the fitting name to each of them,—are we to come and worship images?

Oneness of the Father, Son and Spirit

Are, then, those who consider life to be comprised in this, “Let us eat and drink, for to-morrow we die,” and who regard death as a deep sleep and forgetfulness (“sleep and death, twin brothers”), to be accounted pious; while men who reckon the present life of very small worth indeed, and who are conducted to the future life by this one thing alone, that they know God and His Logos, what is the oneness of the Son with the Father, what the communion of the Father with the Son, what is the Spirit, what is the unity of these three, the Spirit, the Son, the Father, and their distinction in unity;

The catholicity of the Church

But the path of those belonging to the Church circumscribes the whole world, as possessing the sure tradition from the apostles, and gives unto us to see that the faith of all is one and the same, since all receive one and the same God the Father, and believe in the same dispensation regarding the incarnation of the Son of God, and are cognizant of the same gift of the Spirit, and are conversant with the same commandments, and preserve the same form of ecclesiastical constitution, and expect the same advent of the Lord, and await the same salvation of the complete man, that is, of the soul and body.

…For the Church preaches the truth everywhere, and she is the seven-branched candlestick which bears the light of Christ.

One God — two testaments

For all the apostles taught that there were indeed two testaments among the two peoples; but that it was one and the same God who appointed both for the advantage of those men (for whose sakes the testaments were given) who were to believe in God,

God the Father and His Word are one and the same

For to whomsoever the Lord shall say, “Depart from me, ye cursed, into everlasting fire,” these shall be damned for ever; and to whomsoever He shall say, “Come, ye blessed of my Father, inherit the kingdom prepared for you for eternity,” these do receive the kingdom for ever, and make constant advance in it; since there is one and the same God the Father, and His Word, who has been always present with the human race, by means indeed of various dispensations, and has wrought out many things, and saved from the beginning those who are saved, (for these are they who love God, and follow the Word of God according to the class to which they belong,) and has judged those who are judged, that is, those who forget God, and are blasphemous, and transgressors of His word.
