Quit or lay your cards on the table. It's the only two options you have, really.
Laying your cards on the table says, "I know what's going on and it MUST stop."
Quitting says, 'You're NOT hearing me and I DON'T have to endure this."
The truly last option is laying your cards on the table WHILE quitting which says, "I KNOW you're doing X, Y, Z and no one seems to care that I know when I bring it up; so, I'm out!"
Put up two fingers and bounce. Now, you don't have to leave that church, per se, you just don't have to endure all that mess.
Anyway, that's what I would do.
