The accession of Justin I. (518-27) was a triumph for the orthodox faith, to which the people of Constantinople had firmly held. The patriarch, John the Cappadocian, declared his adherence to the Fourth Council: the name of Pope Leo was put on the diptychs together with that of S. Cyril; and synod after synod acclaimed the orthodox faith. Negotiations for reunion with the West were immediately opened. The patriarch and the emperor wrote to Pope Hormisdas, and there wrote also a theologian more learned than the patriarch, the Emperor's nephew, Justinian. "As soon," he wrote, "as the Emperor had received by the will of God the princely fillet, he gave the bishops to understand that the peace of the Church must be restored. This had already in a great degree been accomplished." But the pope's opinion must be taken with regard to the condemnation of Acacius, who was responsible for the Henotikon, and was the real cause of the severance between the churches. [Sidenote: Reunion, 519.] The steps towards reunion may be traced in the correspondence between Hormisdas and Justinian. It was finally achieved on the 27th of March, 519. The patriarch of Constantinople declared that he held the Churches of the old and the new Rome to be one; and with that regard he accepted the four Councils and condemned the heretics, including Acacius. The Church of Alexandria did not accept the reunion; and Severus, patriarch of Antioch, was deposed for his heresy. There was indeed a considerable party all over the East which remained Monophysite; and this party it was the first aim of Justinian (527-65), when he became emperor, to convince or to subdue. He was the {11} nephew of Justin, and he was already trained in the work of government; but he seemed to be even more zealous as a theologian than as a lawyer or administrator. The problem of Monophysitism fascinated him. [Sidenote: The Emperor Justinian.] From the first, he applied himself seriously to the study of the question in all its bearings. Night after night, says Procopius, he would study in his library the writings of the Fathers and the Holy Scriptures themselves, with some learned monks or prelates with whom he might discuss the problems which arose from their perusal. He had all a lawyer's passion for definition, and all a theologian's delight in truth. And as year by year he mastered the intricate arguments which had surged round the decisions of the Councils, he came to consider that a _rapprochement_ was not impossible between the Orthodox Church and those many Eastern monks and prelates who still hesitated over a repudiation which might mean heresy or schism. And from the first it was his aim to unite not by arms but by arguments. The incessant and wearisome theological discussions which are among the most prominent features of his reign, are a clearly intended part of a policy which was to reunite Christendom and consolidate the definition
