About Martin Luther:
Martin Luther was a German friar, priest and professor of theology who was a seminal figure in the Protestant Reformation. Initially an Augustinian friar, Luther came to reject several teachings and practices of the Roman Catholic Church. He strongly disputed the claim that freedom from God's punishment for sin could be purchased with money. He confronted indulgence salesman Johann Tetzel, a Dominican friar, with his Ninety-Five Theses in 1517. His refusal to retract all of his writings at the demand of Pope Leo X in 1520 and the Holy Roman Emperor Charles V at the Diet of Worms in 1521 resulted in his excommunication by the Pope and condemnation as an outlaw by the Emperor.
If I go back home to Wittenberg, I'll lie down in a coffin and give the maggots a fat doctor to eat.
