The patriarchal constitution also contributed to the rise of the Roman Papacy. So early as the three first centuries, the churches of metropolitan towns had enjoyed particular respect. The Council of Nice, in its Sixth Canon, singled out three cities, whose churches had, according to it, an ancient authority over those of the surrounding provinces; these were Alexandria, Rome, and Antioch. The political origin of this distinction is betrayed by the very name which was at first given to the bishop of these cities. He was called Exarch, in the same way as the civil governor.[12] At a later period, the more ecclesiastical name of Patriarch was given to him. This name occurs for the first time in the Council of Constantinople, but in a different sense from that which it received at a later period; for it was only a short time before the Council of Chalcedon, that it was applied exclusively to the great metropolitans. The second ecumenical Council created a new patriarchate, that of Constantinople itself, the new Rome, the second capital of the empire. The Church of Byzantium, so long in obscurity, enjoyed the same privileges, and was put by the Council of Chalcedon in the same rank as the Church of Rome. Rome then shared the patriarchate with these three churches; but when the invasion of Mahomet annihilated the sees of Alexandria and Antioch--when the see of Constantinople decayed, and later, even separated from the west, Rome remained alone, and circumstances rallied all around her see, which from that time remained without a rival. [12] See Canon, Sardic. VI; and also the Council of Chalcedon, Canons 8 and 18, ο εξαρχος της διοικησεως, the exarch of the diocese. New accomplices, the most powerful of all accomplices, came also to her aid. Ignorance and superstition seized upon the Church, and gave her up to Rome with a bandage on her eyes, and chains on her hands. Still this slavery was not completed without opposition. Often did the voice of the churches protest their independence: This bold voice was heard especially in proconsular Africa and the East.[13]
