“ Rome was subject to his exarch at Ravenna.Yet from Constantine and the Nicene Council the advance of Rome's Primacy is perpetual. In Leo I. it is universally acknowledged. At the fall of the western empire Acacius attempts his schism. He is supported while living by the emperor Zeno, and his memory after his death by the succeeding emperor Anastasius, who reigned for twenty-seven years, longer than any emperor since Augustus had reigned over the whole empire. All the acts of these two princes show that they would have liked to attach the Primacy to their bishop at Constantinople. ”
