§ 41.3. =The Schism of the Presbyter Novatian at Rome in A.D. 251.=--In this case the rigorist and presbyterial interests coincide. After the martyrdom of bishop Fabian under Decian in A.D. 250, the Roman bishopric remained vacant for more than a year. His successor Cornelius (A.D. 251-253) was an advocate of the milder practice. At the head of his rigorist opponents stood his unsuccessful rival, Novatian, a learned but ambitious presbyter (§ 31, 12). Meanwhile Novatus, excommunicated by Cyprian at Carthage, had also made his way to Rome. Notwithstanding his having previously maintained contrary principles in the matter of church discipline, he attached himself to the party of the purists and urged them into schism. They now chose Novatian as bishop. Both parties sought to obtain the recognition of the most celebrated churches. In doing so Cornelius described his opponent in the most violent and bitter manner as a mere intriguer, against whose reception into the number of presbyters as one who had received clinical baptism (§ 35, 3) and especially as an energoumenon under the care of the exorcists, he had already protested; further as having extorted a sham episcopal consecration from three simple Italian bishops, after he had attached them to himself by pretending to be a peacemaker, then locking them up and making them drunk, etc. Cyprian, as well as Dionysius of Alexandria, expressed himself against Novatian, and attacked the principles of his party, namely, that the church has no right to give assurance of forgiveness to the fallen or such as have broken their baptismal vows by grievous sin (although the possibility of finding forgiveness through the mercy of God was indeed admitted), and that the church as a communion of thoroughly pure members should never endure any impure ones in its bosom, nor receive back any excommunicated ones, even after a full ecclesiastical course of penitence. The Novatianists had therefore called themselves the Καθαροί. The moral earnestness of their fundamental principles secured for them even from bishops of contrary views an indulgent verdict, and Novatianist churches sprang up over almost all the Roman empire. The Œcumenical Council at Nicæa in A.D. 325 maintained an attitude toward them upon the whole friendly, and in the Arian controversy (§ 50) they stood faithfully side by side with their ecclesiastical opponents in the defence of Nicene orthodoxy, and with them suffered persecution from the Arians. Later on, however, the Catholic church without more ado treated them as heretics. Theodosius the Great sympathizing with them because of such unfair treatment, took them under his protection; but Honorius soon again withdrew these privileges from them. Remnants of the party continued nevertheless to exist down to the 6th century.[111]
