They also have built into the structure a pay your way out of trouble thing going on. I thought the catholics moved on from that old paradigm. Play it again sam.
Another crazy belief system is Eckankar. The inside scoop on that one is especially crazy. There are so many cheeses laid out all leading to the same trap.
Also having seen the goofiness of mormonism from within (as a child), again never throw out the baby with the bathwater. One thing they encourage people to do is to store a couple years of food. Smart practice but you don't need the rest of the incoherent junk that goes along with mormonism to do that. It isn't exclusive to the club, just like sound detoxification practices aren't exclusive to the scientology cult.
