Elder confidentiality is an oxymoron.
Certainly in practice these guys by and large can't be trusted to not talk to their wives and children about little suzie or brother jimmy's indiscretions. However even the ones that aren't prone to being gossiping children, find themselves systemically contributing to this. How?
When someone is accused of something, or a rumor is floated, or someone might have said something negative, someone might have had too much beer.......you name it......they NEVER encourage the person complaining to apply matthew 5 and talk to the person. They ALWAYS bring this info up at the elder meeting, and brothers are assigned to speak to the person. Lets say it was completely false. Does it matter? No the entire body has already heard the accusation,a nd follow up is scant or "bro ___ accepted the counsel with humility". If you argue accuracy, its not like its reported...."we were wrong, should have encouraged the 2 grown ass people to speak to each other, its our bad".
Nope.....elders can slander others to other elders with impugnity.
Anyone serving probably has heard the phrase...
Elder to elder.
