The Ninety-five Theses (Martin Luther) Acrylic Print

The Ninety-five Theses or Disputation on the Power and Efficacy of Indulgences is a list of propositions for an academic disputation written in 1517 by Martin Luther, professor of moral theology at the University of Wittenberg, Germany. Retrospectively considered to signal the birth of Protestantism, this document advances Luther's positions against what he saw as the abuse of the practice of clergy selling plenary indulgences, which were certificates believed to reduce the temporal punishment in purgatory for sins committed by the purchasers or their loved ones. In the Theses, Luther claimed that the repentance required by Christ in order for sins to be forgiven involves only inner contrition, and that sacramental confession is unnecessary.
