Abramius
There was a certain Abramius, an Egyptian by race, who lived a very rough and savage life in the wilderness. Afflicted in his mind by an untimely fancy, he went to the church and contended with the priests, saying: “I have been ordained a priest by Christ this night, accept me as a celebrant.” The fathers removed him from the desert and led him to a less ascetic and calmer life, and cured him of his presumption, bringing this man who had been deluded by the demon to a knowledge of his own weakness.
