Nor would it be unhistorical to note that in proportion as the emperors, whose seat was Byzantium, encroached upon the liberty of the Church, and sought domination over the successor of St. Peter, in whose prerogatives that liberty was seated, their temporal empire declined. The despotism which flung itself with insolence and violence against the Church became odious to its own subjects. We shall see an instance of this which almost passes belief when the patriarchate of St. Athanasius embraces the Moslem conqueror, to escape the Byzantine sovereign, and terms the defenders of the Christian faith Melchites, that is, Royalists, because, while they rejected the Eutychean heresy, they were likewise loyal to the eastern emperor. Let us see how Pope Martin meets this attempt. No sooner is he invested with “the great mantle,”(32) than he summons a Council to meet in the basilica of Constantine, then called the Church of the Saviour, now St. John Lateran, adjoining the papal palace, the Mother Church of Rome. He called this council in order to judge the doctrine which two emperors, using two Byzantine patriarchs, and at the same time used by them, seek to impose upon the Church, instead of the doctrine of St. Leo the Great, accepted and set forth at the Council of Chalcedon. It held from the 5th to the 31st October, 649, five sittings. It was attended by 105 bishops, chiefly from Italy (excluding the Lombard dominion), Sicily and Sardinia, with some African, and a few foreign. The acts have come to us complete, both in Greek and Latin, the former being the proper language of the two documents, the Ecthesis and Typus. I give the following epitome of the Pope’s speech to the Council:—
