“When I agreed to be a member of this religion, everything was different. The end of the world, the Brothers, the congregations, the doctrines. There isn't any love in the congregation anymore. Things have changed. No apologies about the changes or doctrinal reversals , but I am supposed to do what I am told and shut-up.”
It sounds like your mother has the same feelings my dear mother has. She has repeatedly said, "The religion I was baptized into no longer exists. If this religion had existed then I would never have joined."
It is sad though that she is so close to the end of her life that she doesn't dare leave now. Damned cruel JDubya's!
