Christ said, when faced with the woman about to be stoned over alleged adultery, 'Let he who is without sin, throw the first stone!'
Of course there wasn't anyone with out sin and the woman left with her life.
Shunning is 'the living death' for JWs.
Therefore, if they catch a woman, or a woman/man confesses to adultery, why do they then shun them and give them the 'living death'.
My mother was telling me about a young woman who had committed adultery in her cong. and had just married the man she'd had the affair with. She was disgusted that they were allowed to sit together at the KH now and equally disgusted that she now attended all the meetings when she didn't before. 'Who does she think she is?' in her words!
To me, my mother comes out with much blunt JW thought and belief. I asked her if she was a Paulist or a Christian and gave the above example of what Christ said. She did not like it. She threw a strop and stomped off!
Shunning is evil just because it is! But if you claim to be a Christian....why do it?
