After the Decian-Valerian persecution (250-260) the Church enjoyed a long peace, rarely interrupted anywhere by hostile measures, until the outbreak of the second great general persecution, under Diocletian (303-313), a space of over forty years. In this period the Church cast off the chiliasm which had lingered as a part of a primitive Jewish conception of Christianity (§ 47), and adapted itself to the actual condition of this present world. Under the influence of scientific theology, especially that of the Alexandrian school, the earlier forms of Monarchianism disappeared from the Church, and the discussion began to narrow down to the position which it eventually assumed in the Arian controversy (§ 48). Corresponding to the development of the theology went that of the cultus of the Church, and already in the West abiding characteristics appeared (§ 49). The cultus and the disciplinary work of the bishops advanced in turn the hierarchical organization of the Church and the place of the bishops (§ 50), but the theory of local episcopal autonomy and the universalistic tendencies of the see of Rome soon came into sharp conflict (§ 51), especially over the validity of baptism administered by heretics (§ 52). In this discussion the North African Church assumed a position which subsequently became the occasion of the most serious schism of the ancient Church, or Donatism. In this period, also, is to be set the rise of Christian Monasticism as distinguished from ordinary Christian asceticism (§ 53). At the same time, a dangerous rival of Christianity appeared in the East, in the form of Manichæanism, in which were absorbed nearly all the remnants of earlier Gnosticism (§ 54). § 47. The Chiliastic Controversy During the third century the belief in chiliasm as a part of the Church’s faith died out in nearly all parts of the Church. It did not seem called for by the condition of the Church, which was rapidly adjusting itself to the world in which it found itself. The scientific theology, especially that of Alexandria, found no place in its system for such an article as chiliasm. The belief lingered, however, in country places, and with it went no little opposition to the “scientific” exegesis which by means of allegory explained away the promises of a millennial kingdom. The only account we have of this so-called “Chiliastic Controversy” is found in connection with the history of the schism of Nepos in Egypt given by Eusebius, But it may be safely assumed that the condition of things here described was not peculiar to any one part of the Church, though an open schism resulting from the conflict of the old and new ideas is not found elsewhere.
