Early Life

Winfrid, the future Saint Boniface, was born in the year 672 in England. He came from a high nobility family that was respected and prosperous. When he was young, he devoted himself to monastic life. However, his father was against the whole idea because he had other plans for his future. After some time, he agreed, and Winfrid was admitted to the Benedictine monasteries of Adescancastre under the Abbot Winbert. At the abbey school, Winfrid began his teaching career. Through hard work, he climbed the ladder of leadership and was appointed to the position of priest at the age of 30. The first Latin grammar, which was produced in England, was written by Winfrid at the abbey school.

Winfrid went on a missionary expedition to Frisia in 716. He intended to convert the inhabitants by preaching to them in their language. His own Old English language had a similar dialect to Frisian. However, the war between Frankish leader Charles Martel, a Christian, and the pagan Radbod, king of the Frisians, hindered Winfrid from preaching the gospel. This forced him to return to Nursling without making any progress.

Commission and Early Missions

Pope Gregory II had so much faith in Winfrid to such an extent that he gave him a task to preach in Germany in 718. The pope wanted Winfrid to reorganize the Frankish churches and implement Roman Catholic doctrine. After traveling through the German province of Bavaria, he discovered that the churches and monasteries worshipped God in truth and spirit. He also visited the Merovingian duchy of Alamannia, where he found that the churches still followed Roman Catholic doctrine.

However, the central German territory of Thuringia, which was considered Christian by Rome,  rebelled and killed the newly converted Duke Gotzbert and his son, Hethan II. They were attempting to force the populace to accept Christianity. The majority of people in this territory were non-believers who practiced idolatry. Winfrid tried in vain to rectify this horrific situation, which was against the teachings of Jesus Christ.

When King Radbod of Frisia died, Winfrid saw this as an opportunity to preach the Good News and win souls for Jesus Christ. He traveled to Frisia, where he lived for three years under the guidance of St. Willibrord. While he was there, he managed to convert multitudes from paganism. The majority of Christians who had to backslide during the persecution of Radbod returned to worship Jesus Christ in truth and spirit.

After completing his mission in Frisia, Winfrid returned to Thuringia, where he continued spreading the Good News of Jesus Christ. He managed to establish a monastic cell at Amoneburg with the help of two newly converted Germanic chiefs. This was a center where native clergy were to be taught the things of God.

Winfrid’s devotion and dedication led to his appointment as regional bishop by Pope Gregory II on November 30, 722. His name was changed to Boniface, a name that belonged to the legendary fourth-century martyr Boniface of Tarsus. The pope instructed the dioceses of Thuringia and Hesse to obey the new bishop. As the pope’s representative, Boniface was to be protected by the Frankish ruler Charles Martel.

Saint Boniface Destroys Thor’s Oak

Boniface took it upon himself to destroy the pagan places of worship. In the year 723, he cut down

the sacred oak tree dedicated to Thor After destroying Thor’s altar, people expected a form of punishment to be meted out to Boniface by the pagan gods. However, nothing happened to the bishop, and the people immediately converted to Christianity. Boniface did not stop there; he went on to use the oak’s wood to build a chapel at the site. Due to his hard work and dedication, the pope appointed Boniface to the position of Archbishop.

In his endeavor to devote himself completely to the mission of spreading the Gospel of Jesus Christ to the pagan states, Boniface resigned from his Archbishop position in 738. However, Pope Gregory III did not accept his resignation but promoted him further by giving him the authority of a legate of the Holy See.

He was also granted Mainz, an important key Frankish stronghold, as his Metropolitan See in 745. With the authority vested in him, Boniface proceeded to establish the bishoprics of Salzburg, Regensburg, Freising, and Passau.

Death of Boniface

Boniface never lost hope of converting the Frisians. In 754, he traveled again to Frisia, where he baptized a great number of people. He called for a general meeting at a place between Franeker and Groningen. However, a group of armed pagan inhabitants appeared. They were angry with Boniface’s attempt to destroy their native religion. They martyred him on June 5, 754. He was buried in the abbey church of Fulda.


The Orthodox Church recognizes Boniface as a patron saint of Germany. He is portrayed in paintings with a book, pierced by a sword.
