But this very time was also that in which the heresy whose leading doctrine was denial of the Godhead of the Church's founder came from a threatening of supremacy to an end. In Theodorick Arianism seemed to be enthroned for predominance in all the West. His civil virtues and powerful government, his family league of all the western rulers,--for he himself had married Andefleda, sister of Clovis, and had given one daughter for wife to the king of the Vandals in Africa, and another to the king of the Visigoths in France,--was a gage of security. In Gregory's time the great enemy has laid down his arms. He is dispossessed from the Teuton race in its Gallic, Spanish, Burgundian, African settlements. Gregory, at the head of the western bishops who in every country have risked life for the faith of Rome, has gained the final victory. One only Arian tribe survives for a time, ever struggling to possess Rome, advancing to its gates, ruining its Campagna, torturing its captured inhabitants, but never gaining possession of those battered walls, which Totila in part threw down and Belisarius in piecemeal restored. And Gregory, too, is chosen to stop the Anglo-Saxon revel of cruelty and destruction, which has turned Britain from a civilised land into a wilderness, and from a province of the Catholic Church to paganism, from the very time of St. Leo. Two tribes were the most savage of the Teuton family, the Saxon and the Frank. The Frank became Catholic, and Gregory besought the rulers of the converted nation to help his missionaries in their perilous adventure to convert the ultramarine neighbours, still savage and pagan. He also ordered their chief bishop to consecrate the chief missionary to be archbishop of the Angles. As there was a Burgundian Clotilda by the side of Clovis, there was a Frankish Bertha by the side of Ethelbert; and these two women have a glorious place in that second great victory of the Church. The Visigoth and Ostrogoth with their great natural gifts could not found a kingdom. Their heresy deprived the Father of the Son, and they were themselves sterile. Those who denied a Divine Redeemer were not likely to convert a world. But all through Gregory's life the Byzantine spirit of encroachment was one of his chief enemies. The claim of its bishop to be ecumenical patriarch stopped short of the Primacy. But one after another the bishops of that see sought by imperial laws to detach the bishops of Eastern Illyria from their subjection to the western patriarchate. Their nearness to Constantinople, their being subjects of the eastern emperor, helped this encroachment.
