Constantine IV. died in 685, leaving the throne to his son Justinian II. He had reigned since the murder of his father in 668, and the whole course of his reign showed a very favourable contrast with that of Constans II. But greater still, if possible, was to be the contrast presented to his government by that of his son, who succeeded at a most immature age, and showed himself without counsel, self-command, and reason in all that he did. He was the first of several bad and incapable rulers. His tyranny deprived him of the throne after ten years. He was deposed with the Byzantine penalty of an amputated nose. Upon this deposition, in 695, the following twenty-two years produced seven revolutions, putting the imperial power into new hands and new families. One of these violent changes replaced Justinian II., maimed and dishonoured as he was, after a banishment of ten years. But he had learned no prudence, and the inhumanity of his last six years in his second reign exceeded that of his first reign. In those first ten years from 685 to 695 events happened of importance to the Church, which also illustrate the spirit dominant at Constantinople. The condition of the empire required the strictest union with the West. It was pressed severely by the Mohammedan advance. To meet this effectually the reconciliation which had taken place at the Sixth Council was needed to be wisely and temporately maintained. But Justinian II. summoned a Greek Council to meet in the same hall of his palace, called the Dome, in which that Council had been held. It passed a number of canons on discipline, many of which were injurious to the West and only calculated to increase the mutual estrangement. Inasmuch as the Fifth and Sixth General Councils had passed no canons of discipline, this Council held in 692 was to complete that omission. It called itself the Quinisext. The later Greeks even confounded it with the Sixth Council, others contented themselves with saying that “it was held five or six years after it, and by nearly the same Fathers”. It issued a hundred and two canons on discipline. “It seemed as if the bishops of this Council in their disgust at the undeniable superiority of the Roman Church in matters of faith, in which its authority had always at last prevailed and determined the issue, were bent on making good their right of autonomy at least in matters of discipline, and sought to avenge themselves by disapproving Roman customs for that superiority burdensome to Greek vanity.”(138) As a matter of fact these canons had the effect of widening the breach between Latins and Greeks. It is true that in the eighth century all Greeks did not yet count them ecumenical, but in the Iconoclast contest they gained great consideration, and in the ninth century scarcely a Byzantine doubted any longer that they were ecumenical.(139)
