and his successors the position of sovereign princes in Rome, and the territory attached to it. In 756 Pope Stephen II. re-entered Rome as its acknowledged civil sovereign. Yet, in the eighteen years following this event, the last king of the Lombards renewed the ambition of Liutprand and Aistulf, to become the lord of Rome, and the renewal of Pipin’s gift by Charlemagne, in 774, alone closed the momentous contest which, beginning in 726 with an attack on the unarmed Pope, ended in the deliverance of Italy from the most cruel of thraldoms, and made the Pope, who had long been Rome’s only support and benefactor, its temporal as well as its spiritual head. At the time of that event, more than four centuries had passed since Constantine, in 330, consecrated his city on the Bosphorus to be Nova Roma, pursuing his idea to found a capital which should be Christian from its birth, and the centre of a great Christian empire. Five years before the Church had met for the first time in General Council. The object of its meeting was to refute and censure an attack upon the Godhead of its Founder, and the place at which it met was a city immediately on the Asiatic side of the strait, on which what was then Byzantium stood. The position taken by Constantine was to guard with the imperial sword the chamber in which the Church’s bishops sat, to accept their decrees as the utterance of Christ himself, and to add the force of imperial law to the spiritual authority which he acknowledged them of themselves to possess. From the baptism of Byzantium as Nova Roma in 330, fifty years succeed to 380, in which Constantinople becomes the chief seat of the very heresy condemned by the Church at the Council of 325. Its see is sought after immediately as the prize of worldly ecclesiastics in the East. Eusebius, the man who presently became its bishop, deceives Constantine into fostering the heresy which he abhorred: its bishop, Macedonius, was the docile servant of the emperor Constantius in his attempt to change the faith of the Church: its bishop, Eudoxius, nurtured the emperor Valens in the same heresy. But the succession of Popes in Julius, Liberius, and Damasus, frustrated these efforts of the bishops of Nova Roma in the first half century of its promotion: and when Theodosius sat on the throne of Constantine, with his colleagues, Gratian and Valentinian, their law of 380 called upon their peoples “to hold the religion which is proved to have been delivered to the Romans by the divine apostle, Peter, since it has been maintained there from his time to our own”.(254)
