“Demonology and the black arts were the opposite of heresy, not more pious than the Church but impious, seeking communion with the Devil, not God. Adepts in their rites worshiped Lucifer arrayed as the King of Heaven and believed that he and the other fallen angels would recapture Heaven while the Archangel Michael and his fellows would take their places in Hell. A pact with the Devil offered pleasure without penitence, enjoyment of sexuality, riches, and earthly ambitions. If the price was eternal hellfire, that was what many could expect anyway at the Day of Judgment. Though old and indigenous, demonology was never more than an aberration, but insofar as it offered an alternative answer, it was seen by the Church as dangerous.”
