we have received" (The Treatises of Cyprian 1:2). Only by standing fast in learning and doing what Christ commanded does the Christian have security against the onslaughts of the world (The Treatises of Cyprian 1:2). He who does not "must of necessity waver and wander, and, caught away by a spirit of error . . . be blown about; and he will make no advance in his walk towards salvation, because he does not keep the truth of the way of salvation." (The Treatises of Cyprian 1:2) Cyprian says the devil, when he see his idols forsaken and temples deserted by new believers, devises a fraud under "the Christian name to deceive the incautious" (The Treatises of Cyprian 1:3): He has invented heresies and schisms, whereby he might subvert the faith, might corrupt the truth, might divide the unity. Those whom he cannot keep in the darkness of the old way, he circumvents and deceives by the error of a new way.

This happens, beloved brethren, so long as we do not return to the source of truth, as we do not seek the head nor keep the teaching of the heavenly Master. (The Treatises of Cyprian 1:3) Oropeza states, In view of Eusebius (c. 260-340), Simon Magus was the author of heresy (cf. Acts 8:9–24), and the devil is to be blamed for bringing the Samaritan magician to Rome and empowering him with deceitful arts which led many astray (Eus. Hist. Eccl. 2.13). The magician was supposedly
