Exodus 3:16

When I had spoken these words, I continued: “Permit me, further, to show you from the book of Exodus how this same One, who is both Angel, and God, and Lord, and man, and who appeared in human form to Abraham and Isaac, appeared in a flame of fire from the bush, and conversed with Moses.” And after they said they would listen cheerfully, patiently, and eagerly, I went on: “These words are in the book which bears the title of Exodus: ‘And after many days the king of Egypt died, and the children of Israel groaned by reason of the works;’ and so on until, ‘Go and gather the elders of Israel, and thou shalt say unto them, The Lord God of your fathers, the God of Abraham, the God of Isaac, and the God of Jacob, hath appeared to me, saying, I am surely beholding you, and the things which have befallen you in Egypt.’ ” In addition to these words, I went on: “Have you perceived, sirs, that this …

Accordingly all those above-mentioned dogmas appear to have been transmitted from Moses the great to the Greeks. That all things belong to the wise man, is taught in these words: “And because God hath showed me mercy, I have all things.” And that he is beloved of God, God intimates when He says, “The God of Abraham, the God of Isaac, the God of Jacob.” For the first is found to have been expressly called “friend;” and the second is shown to have received a new name, signifying “he that sees God;” while Isaac, God in a figure selected for Himself as a consecrated sacrifice, to be a type to us of the economy of salvation.

The name of “God the Father” had been published to none. Even Moses, who had interrogated Him on that very point, had heard a different name. To us it has been revealed in the Son, for the Son is now the Father’s new name. “I am come,” saith He, “in the Father’s name;” and again, “Father, glorify Thy name;” and more openly, “I have manifested Thy name to men.” That name , therefore, we pray may “be hallowed.” Not that it is becoming for men to wish God well , as if there were any other by whom He may be wished well, or as if He would suffer unless we do so wish. Plainly, it is universally becoming for God to be blessed in every place and time, on account of the memory of His benefits ever due from every man. But this petition also serves the turn of a blessing. …

52. Further, if, in confessing Father and Son, we spoke of two beginnings or two Gods as Marcion and Valentinus, or said that the Son had any other mode of godhead, and was not the Image and Expression of the Father, as being by nature born from Him, then He might be considered unlike; for such essences are altogether unlike each other. But if we acknowledge that the Father’s godhead is one and sole, and that of Him the Son is the Word and Wisdom; and, as thus believing, are far from speaking of two Gods, but understand the oneness of the Son with the Father to be, not in likeness of their teaching, but according to essence and in truth, and hence speak not of two Gods but of one God; there being but one Form of Godhead, as the Light is one and the Radiance; (for this was seen by the Patriarch Jacob, as Scripture says, ‘The sun rose upon him when the Form of God passed by,’ Gen. xxxii. …
