黒魔術
Black magic was that which was used for a malevolent purpose. This was generally dealt with through confession, repentance, and charitable work assigned as penance. Early Irish canons treated sorcery as a crime to be visited with excommunication until adequate penance had been performed. In 1258, Pope Alexander IV ruled that inquisitors should limit their involvement to those cases in which there was some clear presumption of heretical belief.
