She says that if they EVER change thoughts on this doctrine she would immediately leave.
I think - just my opinion - you are chasing your tail with this question. If she hasn't seen enough already (1975, 1995, milawi/mexico, blinking lights, Swaggart tax evasion, UN membership, etc, etc.) I doubt if "one more thing will do it for her either." It's like a parent that lets the kid get away with murder and just keeps saying "If you do that one more time...." I dunno. But we know one thing for sure - if she sticks around long enough they will be forced to address it.
