Simon is the name of a magus mentioned in the canonical book of Acts 8:9ff, in apocryphal texts and elsewhere. In the Book of Acts Simon the Magus is presented as being deeply impressed by the apostle Peter's cures and exorcisms and by the gift of the Spirit that came from the apostles’ laying on of hands; therefore, he "believed and was baptized". But Simon asks the apostles to sell him their special gift so that he can practice it too. This seems to represent the attitude of a professional magician. In other words, for Simon, the power of this new movement is a kind of magic that can be purchased – perhaps a common practice for magicians in parts of the Greco-Roman world. The Apostles response to Simon was emphatic in its rejection. The early church drew a strong line of demarcation between what it practiced and the practices of magic users. As the church continued to develop this demarcation Simon comes under even greater scrutiny in later Christian texts. The prominent Christian author Justin Martyr for example, claims that Simon was a magus of Samaria, and that his followers committed the blasphemy of worshiping Simon as God. The veracity of this is not certain, but proves the desire of the early Christians to escape an association with magic.
