You may have heard the term “Spirtual Satanist” get thrown around at some point. The organization known as Joy of Satan seems to throw that term around quite a bit, and the term is actually generally associated with theistic Satanism.
I personally have a mixed opinion of the term. On the one hand, I think it’s just a phrase thrown around by Joy of Satan, but on the other hand it could be used to refer to Satanists with an interest in mysticism and spirituality, and pursue those things.
Still, I can’t help but be rather careful about that term. I don’t like to be associated with the false Satanists who usually use the term.
