Novatian (200-258) was a scholar, priest, and theologian. He is considered by the Catholic Church to have been an antipope between 251 and 258. Some Greek authors give his name as Novatus, who was an African presbyter. He was a noted theologian and writer, the first Roman theologian who used the Latin language, at a time when there was much debate about how to deal with Christians who had lapsed and wished to return, and the issue of penance. Consecrated as pope by three bishops in 251, he adopted a more rigorous position than the established Pope Cornelius. Novatian was shortly afterwards excommunicated: the schismatic church which he established persisted for several centuries (see Novatianism). Few details are known as to his life. He was a man of learning and had been trained in literary composition. Pope Cornelius, in a letter to Fabius of Antioch, states that a catechumen called Novatian was possessed by Satan for a whole season. "A deep and settled melancholy had fastened on his mind; and the Christians who knew him said that an evil spirit had got possession of him, and that if he would profess Christ the evil spirit would go out of him; so, from a hope of recovering his health, he professed Christianity." Exorcists attended him, but he fell into a sickness from which imminent death was expected; he was, therefore, given baptism by affusion as he lay on his bed. The rest of the rites were not supplied on his recovery, nor was he confirmed by the bishop. "How then can he have received the Holy Ghost?" asked Cornelius. For his profound learning, Cornelius sarcastically defined him as "that creator of dogmas, that champion of ecclesiastical culture", but his eloquence impressed Saint Cyprian of Carthage and Pope Fabian made him a priest despite the protests of the clergy that one who had been baptised only and had not been confirmed could not become a priest.
