The Ecclesiastical History Of Sozomenus by Sozomen
Chapter VI.--Proceedings of John in Asia and Phrygia. Heraclides, Bishop of Ephesus, and Gerontius, Bishop of Nicomedia.
John having been informed that the churches in Asia and the neighborhood were governed by unworthy persons, and that they bartered the priesthood for the incomes and gifts received, or bestowed that dignity as a matter of private favor, repaired to Ephesus, and deposed thirteen bishops, some in Lycia and Phrygia, and others in Asia itself, and appointed others in their stead. The bishop of Ephesus was dead, and he therefore ordained Heraclides over the church. Heraclides was a native of Cyprus, and was one of the deacons under John: he had formerly joined the monks at Scetis, and had been the disciple of the monk Evagrius. John also expelled Gerontius, bishop of the church in Nicomedia. This latter was a deacon under Ambrosius, of the church of Milan; he declared, I do not know why, either with an intention to invent a miracle, or because he had been himself deceived by the art and phantasms of a demon, that he had seized something resembling an ass (onoskelis) by night, had cut off its head, and flung it into a grinding-house. Ambrose regarded this mode of discourse as unworthy of a deacon of God, and commanded Gerontius to remain in seclusion until he had expiated his fault by repentance. Gerontius, however, was a very skillful physician; he was eloquent and persuasive, and knew well how to gain friends; he therefore ridiculed the command of Ambrose, and repaired to Constantinople. In a short time he obtained the friendship of some of the most powerful men at court; and, not long after, was elevated to the bishopric of Nicomedia. He was ordained by Helladius, bishop of Cæsarea in Cappadocia, who performed this office the more readily for him, because he had been instrumental, through his interest at court, in obtaining high appointment in the army for that functionary's son. When Ambrose heard of this ordination, he wrote to Nectarius, the president of the church of Constantinople, desiring him to eject Gerontius from the priesthood, and not permit him and the ecclesiastical order to be so abused. However desirous Nectarius might have been to obey this injunction, he could never succeed carrying it into effect, owing to the determined resistance of the people of Nicomedia. John deposed Gerontius, and ordained Pansophius, who had formerly been preceptor to the wife of the emperor, and who, though a man of decided piety and of a mild and gentle disposition, was not liked by the Nicomedians. They arose in frequent sedition, and enumerated publicly and privately the beneficence of Gerontius, and on the liberal advantage derived from his science, and its generous and active use for the rich and poor alike; and as is usual when we applaud those we love, they ascribed many other virtues to him. They went about the streets of their own city and Constantinople as if some earthquake, or pestilence, or other visitation of Divine wrath had occurred, and sang psalms, and offered supplications that they might have Gerontius for their bishop. They were at length compelled to yield to necessity, and parted with grief and groans from Gerontius, receiving in his stead a bishop whom they regarded with fear and aversion. The bishops who had been deposed and all their followers declaimed against John, as the leader of a revolution in the churches, and as changing the rights of the ordained, contrary to the ancestral laws; and under the influence of their grievance, they condemned deeds done by him, which were worthy of praise according to the opinion of most people. Among other matters, they reproached him with the proceedings that had been taken against Eutropius.
