Acts 8:24

We observe among the arts also some professions liable to the charge of idolatry. Of astrologers there should be no speaking even; but since one in these days has challenged us, defending on his own behalf perseverance in that profession, I will use a few words. I allege not that he honours idols, whose names he has inscribed on the heaven, to whom he has attributed all God’s power; because men, presuming that we are disposed of by the immutable arbitrament of the stars, think on that account that God is not to be sought after. One proposition I lay down: that those angels, the deserters from God, the lovers of women, were likewise the discoverers of this curious art, on that account also condemned by God. Oh divine sentence, reaching even unto the earth in its vigour, whereto the unwitting render testimony! The astrologers are expelled just like their angels. …

Of these the first of all is Simon Magus, who in the Acts of the Apostles earned a condign and just sentence from the Apostle Peter. He had the hardihood to call himself the Supreme Virtue, that is, the Supreme God; and moreover, (to assert) that the universe had been originated by his angels; that he had descended in quest of an erring dæmon, which was Wisdom; that, in a phantasmal semblance of God, he had not suffered among the Jews, but was as if he had suffered .

It seems, then, expedient likewise to explain now the opinions of Simon, a native of Gitta, a village of Samaria; and we shall also prove that his successors, taking a starting-point from him, have endeavoured (to establish) similar opinions under a change of name. This Simon being an adept in sorceries, both making a mockery of many, partly according to the art of Thrasymedes, in the manner in which we have explained above, and partly also by the assistance of demons perpetrating his villany, attempted to deify himself. (But) the man was a (mere) cheat, and full of folly, and the Apostles reproved him in the Acts. With much greater wisdom and moderation than Simon, did Apsethus the Libyan, inflamed with a similar wish, endeavour to have himself considered a god in Libya. …

16. But it will be urged that the bad outside are worse than those within. It is indeed a weighty question, whether Nicolaus, being already severed from the Church, or Simon, who was still within it, was the worse, the one being a heretic, the other a sorcerer. But if the mere fact of division, as being the clearest token of violated charity, is held to be the worse evil, I grant that it is so. Yet many, though they have lost all feelings of charity, yet do not secede from considerations of worldly profit; and as they seek their own, not the things which are Jesus Christ’s, what they are unwilling to secede from is not the unity of Christ, but their own temporal advantage. Whence it is said in praise of charity, that she "seeketh not her own."

“The persecution,” say you, “gained strength.” True, but at that very time to men possessed before (by a hostile power) it brought deliverance. For it planted the miracles like a stronghold, in the heart of the enemy’s country. Not even the death of Stephen quenched their rage, nay, increased it rather: it scattered wide the teachers, so that the greater became the discipleship. “And there was joy.” And yet there had been “great lamentation:” true; but mark again the good, “Of a long time” was the malady, but this man brought them deliverance. And how came he to baptize Simon also? Just as Christ chose Judas. And “beholding the signs” which he did, forasmuch as the others did not receive the (power of working) signs, he durst not ask for it. …
