Lithiumanic Occultism is a moderately followed religion in Minecraft. It revolves around the worship of Lithiumite, either in desire of his favor or selfish purposes. It almost directly counters The Church of Minecraftism, teaching some polar opposites of it. Though Lithiumite is a God, Lithiumanic Occultism is still considered my many to be "heretical devil-worship."
