Under Justinian the Great (527-565), who by conquest reunited Italy with the eastern Empire in 552, the Popes and the Western Church were again subjected to the eastern rule. Like the Patriarch of Constantinople the Pope was now the nominee of the Emperor and could be removed at the pleasure of the prince. Sylverius, made Pope by the Arian Goth

Theodatus, was therefore deposed and exiled by the Emperor's successful general, Belisarius, and a new Pope was chosen. Vigillus, a favourite of the Empress, installed as Pope by Belisarius (537), was peremptorily summoned to Constantinople to answer for his conduct. There a synod was called, and he was excommunicated. His successor, Pelagius I., was apparently appointed directly by the Emperor. Justinian, like Constantine, exercised the right to legislate for every phase of Church life.[297:1] His theory was that "human and divine authority," that is civic and ecclesiastical law, "combining in one and the same act," formed "one true and perfect law for all."[297:2] He meant to exercise a spiritual power very much like the temporal power he wielded. Hence he insisted that the election of a Pope in Rome by the clergy, senate, and people should not be valid until confirmed by him. This practically reduced the Pope of Rome to the position of eastern bishops. The organisation of the Church was guarded and regulated.[297:3] The property of the Church was protected. The jurisdiction of the clergy was clearly defined and minutely regulated as an extension of civil power. In all cases the Emperor was the court of final decision.

This arbitrary interference with the affairs of the Western Church by the imperial authority at Constantinople brought the papal hierarchy to the brink of ruin. The clergy were alarmed at this invasion of the sacred canons of the Council of Chalcedon, and the

unity of the Western Church, which had been so strong for several centuries, was seriously threatened. The clergy of Gaul "silently withdrew from, or boldly renounced their communion with Rome; the Illyrian episcopacy prepared to follow their example"; and Africa became defiant.[298:1] Even the Italian provinces like Venetia and Liguria became disaffected. Pope Pelagius I., indebted to the Emperor for his office, was forced to beg the intervention of the secular arm to compel the ecclesiastical rebels to continue true to their allegiance to the See of Peter. Sorrowful indeed was this spectacle to those who could recall the palmy days of Leo the Great, Felix, Gelasius, and Hormisdas, who had imposed their will on all ecclesiastics, had planted the banner of Roman supremacy in every corner of Christendom, and had even imposed their laws on princes. But it must be remembered that the theory on which Roman leadership rested had not been assailed, and was soon to reassert itself.

In the election of a Pope in 577, the Roman clergy resumed their independence and ventured to consecrate and to inaugurate a successor without even waiting for imperial license. Hence Pelagius II. was the first independently elected Pontiff since the Byzantine conquest of Italy. He reasserted the universal primacy of the Bishop of Rome in a bold tone, and declared that anything done without papal authority was null and void.[298:2] Meanwhile the disaffection in the West had given way to pronounced loyalty to Rome.

Even Pope Gregory the Great did not question the supremacy of the temporal power. He acknowledged the Emperor as his "earthly master" and said that

God had given the ruler dominion even over the priesthood.[299:1] When Emperor Maurice renewed an old edict prohibiting monasteries from receiving soldiers as monks (593), Gregory timidly objected, but quieted his conscience by saying: "What am I but a worm and dust thus to speak to my masters? . . . I have done what was my duty in every particular; I have obeyed the Emperor and have not hushed in silence what I felt to be due to God."[299:2] He attempted, however to carry out the spirit of the law.[299:3] But Gregory the Great was willing to compromise the substantial prerogatives of his office. As the subject of the Emperor, he could yield a point. As Pope he stood as firm as a rock, yet was too wise to provoke a disruption which could bring nothing but injury to the unity and power of the Church.

Popes, like patriarchs, were required to keep an "agent" at the eastern court. The Emperors continued to insist on the right to confirm all papal elections, and, of course, this practically put the election into their hands, as is shown by the elevation of so many "agents" to the papal throne, viz., Vigillus, Pelagius I., Gregory the Great, Sabinian, etc. The Popes, on their installation, were expected to pay tribute to the eastern Emperor.[299:4] Even in questions of doctrine, the Emperor might enforce his will by exiling an obstinate Pope, as in the case of Martin I. (655).

During the period from 552 to 800, the papal power was growing stronger all the time, and only awaited a

favourable opportunity to issue a declaration of independence. The Italians hated both the Greeks and Lombards as foreign masters. Between the two stood the Pope as the only representative of Italian nationality and the sole champion of Italian independence. The Papacy was in theory democratic, and celibacy made a dynasty impossible. The occasion for a declaration of independence was the Iconoclastic Controversy; the leaders were Gregory II. and Gregory III., who formally excommunicated Emperor Leo and his hierarchy; and the new ally to make the independence good was the family of Pepin in Gaul and Germany. After 772, the papal documents do not bear the name of the eastern Emperor.[300:1]
