But there is another among these heretics, Marcus by name, who boasts himself as having improved upon his master. He is a perfect adept in magical impostures, and by this means drawing away a great number of men, and not a few women, he has induced them to join themselves to him, as to one who is possessed of the greatest knowledge and perfection, and who has received the highest power from the invisible and ineffable regions above. Thus it appears as if he really were the precursor of Antichrist.
It appears probable enough that this man possesses a demon as his familiar spirit, by means of whom he seems able to prophesy, and also enables as many as he counts worthy to be partakers of his Charis themselves to prophesy. He devotes himself especially to women, and those such as are well-bred, and elegantly attired, and of great wealth, whom he frequently seeks to draw after him, by addressing them in such seductive words… On the woman replying, “I have never at any time prophesied, nor do I know how to prophesy;” then engaging, for the second time, in certain invocations, so as to astound his deluded victim, he says to her, “Open your mouth, speak whatsoever occurs to you, and you shall prophesy.” She then, vainly puffed up and elated by these words, and greatly excited in soul by the expectation that it is herself who is to prophesy, her heart beating violently [from emotion], reaches the requisite pitch of audacity, and idly as well as impudently utters some nonsense as it happens to occur to her, such as might be expected from one heated by an empty spirit. (Referring to this, one superior to me has observed, that the soul is both audacious and impudent when heated with empty air.) Henceforth she reckons herself a prophetess, and expresses her thanks to Marcus for having imparted to her of his own Chaffs. She then makes the effort to reward him, not only by the gift of her possessions (in which way he has collected a very large fortune), but also by yielding up to him her person, desiring in every way to be united to him, that she may become altogether one with him. – ibid
With good reason, therefore, and very fittingly, in reference to your rash attempt, has that divine elder and preacher of the truth burst forth in verse against you as follows: “Marcus, you former of idols, inspector of portents, skilled in consulting the stars, and deep in the black arts of magic, ever by tricks such as these confirming the doctrines of error, furnishing signs unto those involved by you in deception, wonders of power that is utterly severed from God and apostate, which Satan, your true father, enables you still to accomplish, by means of Azazel, that fallen and yet mighty angel, thus making you the precursor of his own impious actions.” Such are the words of the saintly elder. – ibid
