They are prepping them for something.
DS mentions $$$$, I think this is the most likely scenario. Selling the halls off is step one, but they really can only gain stability with regular cash flow.
Maybe they file bankruptcy with a coinciding settlement of every child abuse case they have out there, clean it all up at once. At the same time, claim persecution and institute a tithe.
Tithing may be the "nasty medicine" that they are getting ready to feed the troops. Gawd knows how much they love the OT, plenty of scriptural tripe they can use to back up a huge cash grab like that.
If they are planning to institute a tithe, they gotta have as many as possible on board. They know they will lose a chunk of people immediately with something like this, so drill it into them obey obey obey because your life depends on it.
