So, again, in the affair of Nestorius as in that of Pelagius, Africa triumphed, and the supremacy of Rome, her ally or confederate, was becoming more and more distinct.

The Eutychian controversy.

A very important result in this gradual evolution of Roman supremacy arose from the affair of Eutyches, the Archimandrite of a convent of monks at Constantinople. He had distinguished himself as a leader in the riots occurring at the time of Nestorius and in other subsequent troubles. Accused before a synod held in Constantinople of denying the two natures of Christ, of saying that if there be two natures there must be two Sons, Eutyches was convicted, and sentence of excommunication passed upon him. This was, however, only the ostensible cause of his condemnation; the true motive was connected with a court intrigue. The chief eunuch, who was his godson, was occupied in a double movement to elevate Eutyches to the see of Constantinople, and to destroy the authority of Pulcheria, the emperor's sister, by Eudocia, the emperor's wife. On his condemnation, Eutyches appealed to the emperor, who summoned, at the instigation of the eunuch, a council to meet at Ephesus. This was the celebrated "Robber Synod," as it was called. It pronounced in favour of the orthodoxy of Eutyches, and ordered his restoration, deposing the Bishop of Constantinople, Flavianus, who was his rival, and at the synod had been his judge and also Eusebius, who had been his accuser. A riot ensued, in which the Bishop of Constantinople was murdered by the Bishop of Alexandria and one Barsumas, who beat him with their fists amid cries of "Kill him! kill him!" The Italian legates made their escape from the uproar with difficulty.

The success of these movements was mainly due to Dioscorus, the Bishop of Alexandria, who thus accomplished the overthrow of his rivals of Antioch and Constantinople. An imperial edict gave force to the determination of the council. At this point the Bishop of Rome intervened, refusing to acknowledge the proceedings. It was well that Alexandria and Constantinople should be perpetually struggling, but it was not well that either should become paramount. Dioscorus thereupon broke off communion with him. Rome and Alexandria were at issue.

Another advance of Rome to power through Eutychianism.

In a fortunate moment the emperor died; his sister, the orthodox Pulcheria, the friend of Leo, married Marcian, and made him emperor. A council was summoned at Chalcedon. Leo wished it to be in Italy, where no one could have disputed his presidency. As it was, he fell back on the ancient policy, and appeared by representatives. Dioscorus was overthrown, and sentence pronounced against him, in behalf of the council, by one of the representatives of Leo. It set forth that "Leo, therefore, by their voice, and with the authority of the council, in the name of the Apostle Peter, the Rock and foundation of the Church, deposes Dioscorus from his episcopal dignity, and excludes him from all Christian rites and privileges."

The rivalry of Constantinople.

But, perhaps that no permanent advantage might accrue to Rome from the eminent position she was attaining in these transactions, when most of the prelates had left the council, a few, who were chiefly of the diocese of Constantinople, passed, among other canons, one to the effect that the supremacy of the Roman see was not in right of its descent from St. Peter, but because it was the bishopric of an imperial city. It assigned, therefore, to the Bishop of Constantinople equal civil dignity and ecclesiastical authority. Rome ever refused to recognize the validity of this canon.

Rivalries of the three great bishops.

In these contests of Rome, Constantinople, and Alexandria for supremacy—for, after all, they were nothing more than the rivalries of ambitious placemen for power—the Roman bishop uniformly came forth the gainer. And it is to be remarked that he deserved to be so; his course was always dignified, often noble; theirs exhibited a reckless scramble for influence, an unscrupulous resort to bribery, court intrigue, murder.
