Apollinarius after thus failing to get the government of the churches, continued, for the future, openly to preach his new fangled doctrine, and constituted himself leader of the heresy. He resided for the most part at Laodicea; but at Antioch he had already ordained Vitalius, a man of excellent character, brought up in the apostolic doctrines, but afterwards tainted with the heresy. Diodorus, whom I have already mentioned, who in the great storm had saved the ship of the church from sinking, had been appointed by the divine Meletius, bishop of Tarsus, and had received the charge of the Cilicians. The see of Apamea Meletius entrusted to John, a man of illustrious birth, more distinguished for his own high qualities than for those of his forefathers, for he was conspicuous alike for the beauty of his teaching and of his life. In the time of the tempest he piloted the assembly of his fellows in the faith supported by the worthy Stephanus. The latter was however translated by the divine Meletius to carry on another contest, for on the arrival of intelligence that Germanicia had been contaminated by the Eudoxian pest he was sent thither as a physician to ward off the disease, thoroughly trained as he had been in a complete heathen education as well as nurtured in the Divine doctrines. He did not disappoint the expectations formed of him, for by the power of his spiritual instruction he turned the wolves into sheep.
