In 719 the missionary monk set out on what was to be a very fruitful venture. He made converts by the thousands. Once, the story goes, he hewed down the giant sacred oak at Geismar to convince the people of Hesse that there was no spiritual power in nature. In 722 the Pope consecrated him bishop for all of Germany. For thirty years Boniface worked to reform and organize the Church, linking the various local communities firmly with Rome. He enlisted the help of English monks and nuns to preach to the people, strengthen their Christian spirit, and assure their allegiance to the pope. About 746 Boniface was appointed archbishop of Mainz, where he settled for several years as head of all the German churches.
Over the years he kept up an extensive correspondence, asking directives of the popes, giving information about the many Christian communities, and relaying to the people the popes' wishes. In 752, as the pope's emissary, he crowned Pepin king of the Franks. In his eighties and still filled with his characteristic zeal, Boniface went back to preach the gospel in Frisia. There, in 754 near the town of Dokkum, Boniface and several dozen companions were waylaid by a group of savage locals and put to death. His remains were later taken to Fulda, where he was revered as a martyr to the Christian faith.
O God, who raised up the holy Bishop and Martyr Saint Boniface from the English nation to enlighten many peoples with the Gospel of Christ: grant, we pray; that we may hold fast in our hearts that faith which he taught with his lips and sealed with his blood; through the same Jesus Christ thy Son our Lord, who liveth and reigneth with thee, in the unity of the Holy Spirit, ever one God, world without end. Amen.
