Kudos. Where do they get their power from? They are humans. They have NO edict from God. Everyone has just as much religious authority as they do.
A bit of confusion on my part - no one is allowed to have birthdays or special days or celebrations, because that would elevate one person above another. Don't they do that every day? They hate the Catholic Church for having a hierarchy that puts people above other people - don't they do the exact same thing? Who are "elders" or "GB" to sit in judgement of other humans? They have NEVER spoken to God - they have to authority to speak for God. If you ask me they pretty much F#@$T^$ED up any right to speak for God at least a dozen times claiming the end of the world on fixed dates. I hope they do get a chance to speak with God - he's pretty pissed at all of them and already has special seating picked out for them.
