Philip Schaff

“ And now also, when the Gentiles are about to be ransomed from the superstition with respect to idols, wickedness, which reigns over them, has by anticipation sent forth her ally like another serpent, even this Simon whom you see, who works wonders to astonish and deceive, not signs of healing to convert and save. Wherefore it behoves you also from the miracles that are done to judge the doers, what is the character of the performer, and what that of the deed. If he do unprofitable miracles, he is the agent of wickedness; but if he do profitable things, he is a leader of goodness. ”
