Shouldn't the teachings of any church be readily available to the public and not through paid tiers or behind copyright if they want to be recognized as a real religion? If they don't, then they stay a cult or secret society, and don't get a tax exemption. Would this cover all the major religions just fine and exclude these weird fringes? For example, Mormons can still have their creepy sealing rituals hidden from public viewing, but they need to document the practice.
And, if scientologists did reveal all their teachings and OT levels to the public, couldn't they just say that without proper auditing, people won't experience the benefits of the higher OT levels? I feel this way, you let people know upfront how crazy a cult they are and not get hundreds of thousands of dollars in debt before learning the truth behind the wall of fire or whatever.
