the Lord cannot be passed over, saying, "Thou art Peter, and upon this rock I will build My Church". They added that the course of five hundred years had exemplified the fact "that the solidity of the Christian religion rests entire and perfect in the Apostolic See". The rebellion of Acacius in 483 drew forth this confession from his successor, John II., in 519. The seven successors of St. Leo stood as one man. No variation in their language or their conduct can be found. Not so the seven successors of Anatolius at Constantinople. That bishop, who had seen himself foiled by the vigour and sagacity of St. Leo at the Council of Chalcedon, lived afterwards on good terms with him, and died in 458, in his lifetime. He was succeeded by Gennadius, who, during the thirteen years of his episcopate, was faithful both to the creed which St. Leo had preserved and to the dignity of the Apostolic See. He was followed by Acacius, who occupied the see from 471 to 489. There was some quality in Acacius which gained the favour of princes. He had charmed at once the old emperor Leo I.; but Zeno, whose influence first made him bishop, afterwards followed all his teaching. He had also gained a renown for orthodoxy by refusing the attempt of Basiliscus to make the imperial will a rule of Church doctrine. It was when his stronger mind had mastered Zeno that he began the desperate attempt against the doctrine and discipline of the Apostolic See which has been our chief subject. But when he died in 489, his successor Fravita at once renounced the position which he had taken up by asking the recognition of Pope Felix and restoring his name in the diptychs. It is true that in his conduct he was double-dealing, and, while he sought for the Pope's recognition, parleyed with the heretical patriarch of Alexandria. But he died in three months, and was succeeded by Euphemius, who likewise repudiated the act of Acacius, and earnestly sought reconciliation with the Pope, while he was unwilling to fulfil the condition of it--that he should erase the name of Acacius from the diptychs. The six years' episcopate of Euphemius was one long contest with the treachery and persecution of the emperor Anastasius, who at last, by help of the resident council, was able to depose him. He placed Macedonius in his stead, who again sought to be reconciled with the Pope, but only would not pay the price of renouncing the person, as he fully renounced the conduct, of Acacius. During fifteen years, from 496 to 511, as Euphemius had resisted the covert heresy of Anastasius, so did Macedonius, and, like him, he fell at last before the enmity of the emperor. Upon the deposition of Macedonius, the emperor obtained the election of Timotheus, who during seven years was his docile instrument. When he died in 518, the bishop John was elected, whose great desire was the restoration of unity, with the maintenance of the faith of Chalcedon. By side of the seven Popes succeeding St. Leo put the seven
