Answer
In 1326, Pope John XXII issued a papal bull condemning the practice of witchcraft, which he declared to be heresy. The bull, titled "Summis desiderantes affectibus", ordered inquisitors to investigate and prosecute anyone suspected of witchcraft. It also listed a number of specific acts that were considered to be witchcraft, such as causing harm to others, using magic to control the weather, and making pacts with the devil.
