Johann Tetzel's Indulgence

Origins
Excerpt from Wikipedia:

Johann Tetzel was a Roman Catholic German Dominican friar and preacher. In addition, he was a Grand Inquisitor of Heresy to Poland, and later became the Grand Commissioner for indulgences in Germany. Tetzel was reputedly known for selling indulgences in exchange for money, which allow a remission of temporal punishment due to sin, the guilt of which has been forgiven, a position heavily challenged by Martin Luther.
