Isaias 46:9

4. As, then, they represent all material substance to be formed from three passions, viz., fear, grief, and perplexity, the account they give is as follows: Animal substances originated from fear and from conversion; the Demiurge they also describe as owing his origin to conversion; but the existence of all the other animal substances they ascribe to fear, such as the souls of irrational animals, and of wild beasts, and men. And on this account, he (the Demiurge), being incapable of recognising any spiritual essences, imagined himself to be God alone, and declared through the prophets, “I am God, and besides me there is none else.” They further teach that the spirits of wickedness derived their origin from grief. …

2. This God, then, being acknowledged, as I have said, and receiving testimony from all to the fact of His existence, that Father whom they conjure into existence is beyond doubt untenable, and has no witnesses [to his existence]. Simon Magus was the first who said that he himself was God over all, and that the world was formed by his angels. Then those who succeeded him, as I have shown in the first book, by their several opinions, still further depraved [his teaching] through their impious and irreligious doctrines against the Creator. These [heretics now referred to], being the disciples of those mentioned, render such as assent to them worse than the heathen. For the former “serve the creature rather than the Creator,” and “those which are not gods,” notwithstanding that they ascribe the first place in Deity to that God who was the Maker of this universe. …

Meanwhile you must believe that Sophia has the surnames of earth and of Mother, “Mother-Earth,” of course, and (what may excite your laughter still more heartily) even Holy Spirit. In this way they have conferred all honour on that female, I suppose even a beard, not to say other things. Besides, the Demiurge had so little mastery over things, on the score, you must know, of his inability to approach spiritual essences, (constituted as he was) of animal elements, that, imagining himself to be the only being, he uttered this soliloquy: “I am God, and beside me there is none else.” But for all that, he at least was aware that he had not himself existed before. He understood, therefore, that he had been created, and that there must be a creator of a creature of some sort or other. …

For when Isaiah hurls denunciation against our very heretics, especially in his “Woe to them that call evil good, and put darkness for light,” he of course sets his mark upon those amongst you who preserve not in the words they employ the light of their true significance, (by taking care) that the soul should mean only that which is so called, and the flesh simply that which is confest to our view, and God none other than the One who is preached. Having thus Marcion in his prophetic view, he says, “I am God, and there is none else; there is no God beside me.” And when in another passage he says, in like manner, “Before me there was no God,” he strikes at those inexplicable genealogies of the Valentinian Æons. …

2. How hard hearted we are and how merciful God is! who even after our many sins urges us to seek salvation. Yet not even so are we willing to turn to better things. Hear the words of the Lord: “If a man put away his wife, and she go from him, and become another man’s and shall afterwards desire to return to him, will he at all receive her? Will he not loathe her rather? But thou hast played the harlot with many lovers: yet return again to me, saith the Lord.” In place of the last clause the true Hebrew text (which is not preserved in the Greek and Latin versions) gives the following: “thou hast forsaken me, yet return, and I will receive thee, saith the Lord.” Isaiah also speaking in the same sense uses almost the same words: “Return,” he cries, “O children of Israel, ye who think deep counsel and wicked. Return thou unto me and I will redeem thee. …
