St. Boniface was said to have had an interesting encounter with the vikings while on a missions trip. They had a sacred tree called The Oak of Thor which the believed was under the protection of Thor and that no one could ever harm it. Of course not being a believer of Norse Mythology, St. Boniface proceeded to cut down the old oak tree. When he was not struck dead by Thor's Bolt many of the Norsemen were dumbfounded. Through this act he gained many converts, although it could probably assumed he also made many enemies.
