This is so maddening, I feel for you.
I want to be sarcastic, and make comments like: "Oh, I feel so loved by God, and this convinces me it is the truth!" and "I think I'll start going back to meetings right now!" with a followup of: "I wonder what blackmail is?"
The people left in are getting more and more "obedient".. How is this any different than Hitler & the Nazis?
Make sure that you make friends with other people outside of this terribly mean organization.
