You can have a religion without any belief in the supernatural, which is not directed by dogma, and which does not rest on Platonic constructs. Religions have always served a purpose in terms of social organization, mutual well-being, and expediency of communication by way of tacit agreements, and, as such, do possess social value, yet they have traditionally done this in the context of dogmatic, arbitrary supernaturalism or outright theism, thereby diminishing or entirely eliminating said social value.
Centuries past the Enlightenment, as science and reason continue to expand the depth and breadth of our perception of physical reality, we can still benefit from the community-building aspects of religion without accepting irrational, arbitrary components derived from mysticism. The same logic that compels someone to plead that we ‘live a life around what we love’ can be used to construct a community framework — a religion — around what we love.
In other words, Ave Satanas.
