But in all other points the Henoticon is little short of a surrender to the people of the right to choose their own creed; it styles Mary the mother of God, and allows that the decrees of the council of Nicaea and Constantinople contain all that is important of the true faith. John, when banished by Zeno, like many of the former deposed bishops, fled to Rome for comfort and for help. There he met with the usual support; and Felix, Bishop of Rome, wrote to Constantinople, remonstrating with Zeno for dismissing the patriarch. But this was only a small part of the emperor's want of success in his attempt at peace-making; for the crafty Peter, who had gained the bishopric by subscribing to the peace-making edict, was no sooner safely seated on his episcopal throne than he denounced the council of Chalcedon and its decrees as heretical, and drove out of their monasteries all those who still adhered to that faith. Nephalius, one of these monks, wrote to the emperor at Constantinople in complaint, and Zeno sent Cosmas to the bishop to threaten him with his imperial displeasure, and to try to re-establish peace in the Church. But the arguments of Cosmas were wholly unsuccessful; and Zeno then sent an increase of force to Arsenius, the military prefect, who settled the quarrel for the time by sending back the most rebellious of the Alexandrians as prisoners to Constantinople. Soon after this dispute Peter Mongus died, and fortunately he was succeeded in the bishopric by a peacemaker. Athanasius, the new bishop, very unlike his great predecessor of the same name, did his best to heal the angry disputes in the Church, and to reconcile the Egyptians to the imperial government. Hierocles, the Alexandrian, was at this time teaching philosophy in his native city, where his zeal and eloquence in favour of Platonism drew upon him the anger of the Christians and the notice of the government.
