In 1516, Johann Tetzel, a Dominican friar and papal commissioner for indulgences, was sent to Germany by the Roman Catholic Church to sell indulgences to raise money to rebuild St. Peter's Basilica in Rome. Roman Catholic theology stated that faith alone, whether fiduciary or dogmatic, cannot justify man; justification rather depends only on such faith as is active in charity and good works (fides caritate formata). The benefits of good works could be obtained by donating money to the church. On 31 October 1517, Luther wrote to his bishop, Albert of Mainz, protesting the sale of indulgences. He enclosed in his letter a copy of his "Disputation of Martin Luther on the Power and Efficacy of Indulgences", which came to be known as The Ninety-Five Theses. This book show his work.
