The pope secured recognition of his supremacy largely because much of the west was Christianized through his efforts. The mission established by Augustine in England was one of the most important missionary undertakings of the pope because it succeeded in making England Roman Catholic. And not only that, but after the conversion of England, Englishmen were largely instrumental in Christianizing many parts of Europe and in subjecting them to the bishop of Rome. Thus it was an Englishman, Boniface, who organized the church in Germany and put it under papal control. By English and German missionaries the barbarians to the north and east of Germany, that is, the Danes, Norwegians, Swedes, Poles, Bohemians, and Hungarians, were Christianized and made tributary to the pope. 23. ... Gregory was divinely led to send Augustine, the servant of God, and with him several other pious monks to preach the word of God to the English.... 25. ... So Augustine and the servants of Christ who were with him came into Britain. At that time Ethelbert was king in Kent. He was a powerful king and had extended the boundaries of his realm to the Humber river, which separates the English of the north from those of the south. On the east shore of Kent there is a small island called Thanet, about large enough for 600 families, according to the English way of reckoning.... Here Augustine, the servant of the Lord, landed with his companions, who, it is said, numbered about forty. At the suggestion of the pope, they brought with them some Franks as interpreters. They sent word to Ethelbert that they had come from Rome, bearing good tidings which would surely bring to all who obeyed them eternal joy in heaven and a kingdom without end with the true and living God. The king ordered them to remain where they were and to be supplied with food until he should make up his mind what to do with regard to them. For he already knew about Christianity. Indeed his wife, Bertha, of the royal family of the Franks, was a Christian. Her family had consented to her marriage with Ethelbert only on the condition that she should be permitted to remain faithful to her religion, and, to aid her in this, they had sent with her a bishop named Liudhard.
