Many forms of satanism, perhaps most?, aren't religious and do not believe in a literal Satan or in Christianity. Satan is used as a symbol of individualism, skepticism, and resistance to religious authority. For many satanists, it's less about worship and more about expressing values like personal autonomy and separation of church and state.

I have a lot of Satanist friends. I'm all for individualism, skepticism, and resistance to religious authorities, but I personally prefer to do it without all the satanic imagery. Just to tease, I occasionally remind them that their beliefs are too Christian for me. Haha. 😈
