Just like an argument on religion, this topic seems not to let go. But I did think I should mention that there was a time, not so long ago, when you were defined as either a card carrying Christian or in opposition to this; as an atheist or agnostic. With fledgling multiculturalism in the early seventies, we now have a plethora of nonChristian faiths: Buddhism, Hinduism, Jainism, Bahai, Islam, Judaism...
There's probably even a few Zoroastrians, who are interesting for the many similarities between Zarathusthra and the Christian 'Son of Man'.
Satanists, of course, as with atheists and agnostics, are largely defined in relation to belief in Christ. (We don't think of atheists as 'not believing in Vishnu' after all.)But then Ceremonial Magic and study of the Kaballah are also closely aligned, even if their practices would dismay the average churchgoer.
You didn't think I'd miss an opportunity to post a link to witchcraft did you? Because that is again on the ascendancy. Though jostling with the more costly and trendy New Age.
Having religiously documented all the things I can think of that might see you bowing down, lighting candles, chomping devotionally, or otherwise sitting crosslegged and contemplating the ineffable, I'm done.
