Simon Magus

“Philip, however, one of those who had been ordained with Stephen to the diaconate, was among those dispersed. He went to Samaria and, filled with divine power, was the first to preach the word there. So great was the divine grace at work with him that even Simon Magus and many others were captivated by his words. Simon had gained such fame by the wizardry with which he controlled his victims that he was believed to be the Great Power of God. But even he was so overwhelmed by the wonders Philip performed through divine power that he insinuated himself [into the faith], hypocritically feigning belief in Christ even to the point of baptism. (This is still done by those who continue his foul heresy to the present day [e.g., “Simony”]: following the practice of their progenitor, they fasten on to the church like a noxious and scabby disease, destroying all whom they succeed in smearing with the dreadful, deadly poison hidden in them. But most of these have been expelled by now, just as Simon himself paid the proper punishment once his real nature was exposed by Peter.)” (Eusebius, The Church History, Translated by Paul L. Maier, 59)
