For whatever reason I was thinking on the topic of Jehovah's Witnesses' practice of disfellowshipping its members based on the concept of preventing "bringing reproach on Jehovah's name". Follow me if you will -
Over 20 years ago a friend of mine did something rather crazy; he committed a major crime. This incident was actually covered by the local tv news and newspaper. As a result he was disfellowshipped on the spot. 3 elders from his congregation met, without him (he was sitting in the county jail), and decided to DF him. Their reason - to prevent bringing reproach on Jehovah's name.
Now then, speak to any JW or any Christian or even practicing Jew and ask them "What is the first thing you think of when thinking of David from the Old Testament?" No doubt the first thing they will bring up is how much faith he had when facing the giant Goliath in battle or the self control and devotion he showed when he didn't slay King Saul when he had the chance.
What they probably won't say it "Oh, King David? He is that scum that used his position to coerce another man's wife to sleep with him. Then, when she ended up pregnant, he called her husband back from a battle the nation was fighting so the husband could sleep with his wife to deceive people into thinking the child was his. Then David sent the man back to battle with orders that assured his death to cover up the whole thing."
The end result - David got to remain King, but wasn't allowed to build Jehovah's temple. Then, David was immortalized in the Bible and his family line brought forth the Messiah, Jesus.
The fact of the matter is this - nothing any person can do can bring reproach on a god. So, what is actually happening here is this - Witnesses are being punished through shunning because they did something that might bring reproach on the ORGANIZATION. Even this is non-sensical because the organization never takes responsibility for its own faults. In word the organization says it is imperfect, it practice it holds itself out to be infallible.
