June 6 is the feast day of Boniface, Archbishop of Mainz, Missionary to Germany, and Martyr, 754. Boniface is justly called one of the “Makers of Europe.” He was born at Crediton in Devonshire, England, about 675, and received the English name of Winfred. He was educated at Exeter, and later at Nursling, near Winchester, where he was professed a monk and ordained to the presbyterate.
Inspired by the examples of Willibrord and others, Winfred decided to become a missionary, and made his first Journey to Frisia (Netherlands) in 716— a venture with little success. In 719 he started out again; but this time he first went to Rome to seek papal approval. Pope Gregory the Second commissioned him to work in Germany, and gave him the name of Boniface.
For the rest of his days, Boniface devoted himself to reforming, planting, and organizing churches, monasteries, and dioceses in Hesse, Thuringia, and Bavaria. Many helpers and supplies came to him from friends in England. In 722 the Pope ordained him a bishop, ten years later made him an archbishop, and in 743 gave him a fixed see at Mainz.
The Frankish rulers also supported his work. At their invitation, he presided over reforming councils of the Frankish Church; and in 752, with the consent of Pope Zacharias, he anointed Pepin (Pippin) as King of the Franks. Thus, the way was prepared for Charlemagne, son of Pepin, and the revival of a unified Christian dominion in western Europe.
In 753 Boniface resigned his see, to spend his last years again as a missionary in Frisia. On June 5, 754, while awaiting a group of converts for confirmation, he and his companions were murdered by a band of pagans, near Dokkum. His body was buried at Fulda, a monastery he had founded in 744, near Mainz.
