Boniface (ca 672-754; fl. >716) is, like Willibrord, both born in Britannia and a Benedictine monk. He even gains his first experience as a missionary ministering with Willibrord in Frisia (716). When Boniface travels to Rome, the pope sends him as a missionary to Germania (719).
On one occasion, while preaching the Good News of Jesus Christ and challenging the devotion of the Germani to the Olympian gods, Boniface approaches a large and ancient oak tree sacred to Jupiter. He dares the god to strike him dead as he buries his axe in its trunk. Instead, a sudden gust of wind drops the tree. All the Olympians present instantly choose to become Christians. Thousands more do so in response to his preaching.
While Boniface is again strengthening the Church in Frisia, bandits kill him and his companions to steal their gold and silver vessels (754). Instead they find only books.
