Isaias 42:8

And Trypho said, “Being shaken by so many Scriptures, I know not what to say about the Scripture which Isaiah writes, in which God says that He gives not His glory to another, speaking thus ‘I am the Lord God; this is my name; my glory will I not give to another, nor my virtues.’ ”

And I answered, “If you spoke these words, Trypho, and then kept silence in simplicity and with no ill intent, neither repeating what goes before nor adding what comes after, you must be forgiven; but if [you have done so] because you imagined that you could throw doubt on the passage, in order that I might say the Scriptures contradicted each other, you have erred. But I shall not venture to suppose or to say such a thing; and if a Scripture which appears to be of such a kind be brought forward, and if there be a pretext [for saying] that it is contrary [to some other], since I am entirely convinced that no Scripture contradicts another, I shall admit rather that I do not understand what is recorded, and shall strive to persuade those who imagine that the Scriptures are contradictory, to be rather of the same opinion as myself. …

In Isaiah: “Be comforted, ye weakened hands; and ye weak knees, be strengthened. Ye who are of a timorous heart, fear not. Our God will recompense judgment, He Himself will come, and will save us. Then shall be opened the eyes of the blind, and the ears of the deaf shall hear. Then the lame man shall leap as a stag, and the tongue of the dumb shall be intelligible; because in the wilderness the water is broken forth, and the stream in the thirsty land.” Also in that place: “Not an elder nor an angel, but the Lord Himself shall deliver them; because He shall love them, and shall spare them, and He Himself shall redeem them.” Also in the same place: “I the Lord God have called Thee in righteousness, that I may hold Thine hand, and I will comfort Thee; and I have given Thee for a covenant of my people, for a light of the nations; to open the eyes of the blind, to bring forth them that are b …

Him, then, we acknowledge and know to be God, the Creator of all things, Lord on account of His power, Parent on account of His discipline, Him, I say, who “spake, and all things were made;” He commanded, and all things went forth: of whom it is written, “Thou hast made all things in wisdom;” of whom Moses said, “God in heaven above, and in the earth beneath;” who, according to Isaiah, “hath meted out the heaven with a span, the earth with the hollow of His hand;” “who looketh on the earth, and maketh it tremble; who boundeth the circle of the earth, and those that dwell in it like locusts; who hath weighed the mountains in a balance, and the groves in scales,” that is, by the sure test of divine arrangement; and lest its greatness, lying unequally, should easily fall into ruins if it were not balanced with equal weights, He has poised this burden of the earthly mass with equity. …

VII. Let us look also at what follows. What says the most divine evangelist? When the Lord had entered into the temple, the blind and the lame came to Him; and He healed them. And when the chief priests and Pharisees saw the wonderful things that He did, and the children crying, and saying, Hosanna to the Son of David: Blessed is He that cometh in the name of the Lord, they brooked not this honour that was paid Him, and therefore they came to Him, and thus spake, Hearest Thou not what these say? As if they said, Art Thou not grieved at hearing from these innocents things which befit God, and God alone? Has not God of old made it manifest by the prophet, “My glory will I not give unto another;” and how dost Thou, being a man, make Thyself God? But what to this answers the long-suffering One, He who is abundant in mercy, and slow to wrath? He bears with these frenzied ones; with an apology …

50. If then any think of other beginning, and other Father, considering the equality of these attributes, it is a mad thought. But if, since the Son is from the Father, all that is the Father’s is the Son’s as in an image and Expression, let it be considered dispassionately, whether an essence foreign from the Father’s essence admit of such attributes; and whether such a one be other in nature and alien in essence, and not coessential with the Father. …

“Existing in the Beginning,” he says, “not without beginning.” In what fashion does he who plumes himself on his superior discernment understand the oracles of God? He declares Him Who was in the beginning Himself to have a beginning: and is not aware that if He Who is in the beginning has a beginning, then the Beginning itself must needs have another beginning. Whatever He says of the beginning he must necessarily confess to be true of Him Who was in the beginning: for how can that which is in the beginning be severed from the beginning? and how can any one imagine a “was not” as preceding the “was”? For however far one carries back one’s thought to apprehend the beginning, one most certainly understands as one does so that the Word which was in the beginning (inasmuch as It cannot be separated from the beginning in which It is) does not at any point of time either begin or cease its ex …

XVIII. As far then as we can reach, He Who Is, and God, are the special names of His Essence; and of these especially He Who Is, not only because when He spake to Moses in the mount, and Moses asked what His Name was, this was what He called Himself, bidding him say to the people “I Am hath sent me,” but also because we find that this Name is the more strictly appropriate. For the Name Θεός (God), even if, as those who are skilful in these matters say, it were derived from Θέειν (to run) or from Αἴθειν (to blaze), from continual motion, and because He consumes evil conditions of things (from which fact He is also called A Consuming Fire), would still be one of the Relative Names, and not an Absolute one; as again is the case with Lord, which also is called a name of God. I am the Lord Thy God, He says, that is My name; and, The Lord is His name. …
