There are many definitions. But by my definition they are witch’s magical beasts
I think its because traditional witches reject(ed) most of what those religions stand for, the edicts and actions of the major institutions and governments led by those religions, and because in many of the places those religious institutions rule, traditional witchcraft or the activities of traditional witches are usually deemed punishable, sometimes by death or at they are told they will be punished eternally in a lake of fire for being different.
People who are able to ignore that, explain away the abhorrent doctrines and statements in the bible and find joy in some of the kinder parts of the bible are wonderful and I welcome them at my table. I appreciate their transformation of the religion into what they feel is a truer meaning. If they do not believe I am condemned to a lake of fire for not holding the same faith as them, we are as kindred. Christian witches most definitely fall under this hospitality for me. Their interest in and ability to rehabilitate the abrahamic traditions is to some extent commendable, though not something I am driven to take up myself.
Attitudes like mine have long been the case among a majority of traditional witches. Most are allied with people of any number of traditions—though no one like to sit with people who believe they are locked out of “heaven”. In fact many traditional witches adore Mary, Mary Magdalene, many of the Saints and many of the rebellious figures of abrahamic traditions as well (Fallen Angels, Lucifer, Lilith, Eve, Cain and so on). Some traditional witches even call on the Trinity while not necessarily liking the church institution nor some of the rules.
