Isn't it unbelievable that a Jehovah's Witness must accept whatever the Organization says or they can be disfellowshipped??
Unless THEY tell you that their understanding has changed, you cannot believe anything unless they say it's ok.
Many years ago I questioned them about their ridiculous view that whenever the word "heart" was mentioned, it was a literal blood filled organ. I suggested it was symbolic. They sent me and my elders letters telling me to "wait on Jehovah" and spend my time preaching rather than question their correctness!
