10. Here, now, we must beware of the heresy of the Manicheans, which affirms that there is a certain principle of evil, and a certain family of darkness with its princes, which had the presumption to fight against God; but that God, not to let His kingdom be subdued by the hostile family, despatched against them, as it were, His own offspring, princes of His own [kingdom of] light; and so subdued that race from which the devil derives his origin. From thence, also, they say our flesh derives its origin, and accordingly think the Lord said, “Ye are of your father the devil,” because they were evil, as it were, by nature, deriving their origin from the opposing family of darkness. So they err, so their eyes are blinded, so they make themselves the family of darkness, by believing a falsehood against Him who created them. For every nature is good; but man’s nature has been corrupted by an evil will. What God made cannot be evil, if man were not [a cause of] evil to himself. But surely the Creator is Creator, and the creature a creature [a thing created]. The creature cannot be put on a level with the Creator. Distinguish between Him who made, and that which He made. The bench cannot be put on a level with the mechanic, nor the pillar with its builder; and yet the mechanic, though he made the bench, did not himself create the wood. But the Lord our God, in His omnipotence and by the Word, made what He made. He had no materials out of which to make all that He made, and yet He made it. For they were made because He willed it, they were made because He said it; but the things made cannot be compared with the Maker. If thou seekest a proper subject of comparison, turn thy mind to the only-begotten Son. How, then, were the Jews the children of the devil? By imitation, not by birth. Listen to the usual language of the Holy Scriptures. The prophet says to those very Jews, “Thy father was an Amorite, and thy mother a Hittite.” The Amorites were not a nation that gave origin to the Jews. The Hittites also were themselves of a nation altogether different from the race of the Jews. But because the Amorites and Hittites were impious, and the Jews imitated their impieties, they found parents for themselves, not of whom they were born, but in whose damnation they should share, because following their customs. But perhaps you inquire, Whence is the devil himself? From the same source certainly as the other angels. But the other angels continued in their obedi
