At the time of the Reformation, the sale of indulgences had become a major financial boon for the Catholic Church, and a German monk by the name of Johann Tetzel was charged with the task of raising money for the rebuilding of St. Peter’s in Rome.

Martin Luther made Johann Tetzel famous—or infamous— because of Tetzel’s nondisputed quote: “As soon as the gold in the casket rings; the rescued soul to heaven springs.”
