Commercialization of religion

The practice of indulgences has at times been improperly used either through "untimely and superfluous indulgences" by which the power of the keys was humiliated and penitential satisfaction weakened, or through the collection of "illicit profits" by which indulgences were blasphemously defamed. But the Church, in deploring and correcting these improper uses "teaches and establishes that the use of indulgences must be preserved because it is supremely salutary for the Christian people and authoritatively approved by the sacred councils; and it condemns with anathema those who maintain the uselessness of indulgences or deny the power of the Church to grant them.
