Luciferians were a fourteenth century Gnostic sect who worshipped Lucifer, believing him to be the brother of God and wrongly cast out of heaven. The sect seemed to originated in Austria, spreading to Brandenburg, Bohemia, and Switzerland. Fourteen men and women, in 1336, were burned by the Inquisition at Magdelburg for their heretical beliefs about Lucifer. In 1386, a Prenzlau priest accused his whole congregation of believing Lucifer was God, or the brother of God. It is said that some sect members desecrated Eucharistic wafers in the presence of a figure of Lucifer. A.G.H.
