The accurate descriptions of Martin Luther are:
- He was a professor of biblical studies who publicly posted 95 theses that led to the Protestant Reformation.
- He was a monk who criticized the Church for selling indulgences, and he translated the Bible into German.
The other responses regarding him being a charismatic friar selling indulgences or being the Roman Catholic pope are not correct. Martin Luther criticized the sale of indulgences but did not sell them himself, and he was not a pope.
