The persecution of heresy was carried out by Constantine with all the ardour of a convert. An edict confiscated the public property of the heretics to the use either of the revenue or the Catholic Church, and the penal regulations of Diocletian against the Christians were now employed against the schismatics. The Donatists, who maintained the apostolic succession of Donatus, primate of Carthage, as opposed to Cæcilian, were suppressed in Africa, and a general synod attempted to regulate the faith of the Church. The subject of the nature of the divine Trinity had early given rise to discussion. Of the three main heretical views, that of Arius and his disciples was the most prevalent. He held in effect that the Son, by whom all things were made, though He had been begotten before all worlds, yet had not always existed. He shone only with the reflected light of His Almighty Father, and, like the sons of the Roman emperors, who were invested with the titles of Cæsar or Augustus. He governed the universe. The Tritheists advocated a system which seemed to establish three independent deities, while the Sabellian theory allowed only to the man Jesus the inspiration of the divine wisdom. The consubstantiality of the Father and of the Son had been established by the Council of Nicæa in 325, but the East ranged itself for the most part under the banner of the Arian heresy. At first indifferent, Constantine at last persecuted the Arians, who later, under Constantius, were received into favour. Constantinople, which for forty years was the stronghold of Arianism, was converted to the orthodox faith under Theodosius by Gregory Nazianzen. _IV.--The Conversion of the World_ The pagan religion was finally destroyed about the year 390, and the faintest vestiges of it were not visible thirty years later. Its influence, however, might be observed in many of the ceremonies which were introduced into the Church, and the worship of martyrs and relics seemed to revive a system of polytheism by the worship of a hierarchy of saints. Among the most famous of the dignitaries of the Church at this period was the Archbishop of Constantinople, who was distinguished by the epithet of Chrysostom, or the Golden Mouth. He attempted to purify the eastern empire, excited the animosity of the Empress Eudoxia, and died in exile in 407. The monastic system had been founded by Antony, an illiterate youth, in the year 305, by the establishment on Mount Cobyim, near the Red Sea, of a colony of ascetics, who renounced all the business and pleasures in life as the price of eternal happiness. A long series of hermits, monks, and anachorets propagated the system and, patronised by Athanasius, it spread to all parts of the world.
