Pope Constantine is the fifth and also the last Pope who paid a visit to Constantinople. As these visits cast an important light upon the condition during two hundred years under which, being acknowledged as successors of St. Peter, they exercised as subjects in the civil order their supreme authority in the Church, I think it belongs to the matter now treated to refer to the facts and results of each visit. Pope John I., who sat from 523 to 525, was a subject of King Theodorich, and was summoned by him to Ravenna. There he was compelled, much against his will, to go with three senators on an embassy to the emperor Justin I. Theodorich was most indignant that the emperor had required Arians in his empire to give back their churches to the Catholics. He threatened the Pope that if this treatment was not reversed he would drown Italy in blood.(159) So the Pope, being sick, went with the senators to Constantinople. On their arrival the whole city went out with wax lights and bannered crosses in honour of the blessed Apostles, Peter and Paul, for the Greeks testified that from the time of Constantine and St. Silvester they had never merited to receive a successor of St. Peter. Then the emperor Justin, doing honour to God, threw himself to the ground upon his face and worshipped the most blessed Pope John. Pope John and the senators besought him with many tears to accept their legation. The emperor rejoiced that he had been found worthy to see in his kingdom a successor of St. Peter and was gloriously crowned by his hands. When they returned with success to King Theodorich at Ravenna they found that he had imprisoned the two illustrious senators, Symmachus and Boethius; he put the Pope likewise in prison, and so the bishop of the first see suffered affliction in ward, and died of want. Ninety-eight days after his death in prison the heretical King Theodorich by the will of God suddenly died.
