Like I mentioned first, I do agree with the overall premise, but I guess I've just been involved in congregational leadership too long and have seen some interesting things go on that may not necessarily rise to life/death, but are certainly threatening of vigorous health to make an absolute pact.
I hear ya, me too. What I have seen all too often though is even when it IS necessary to discuss among leadership, folks go beyond that and share with those outside of leadership.
From a Jewish cultural perspective it's absolutely insane the practice of some denominations to have people actually make public confessions to the entire assembly; lashon hara-ing themselves, ie. suicide.
I see this as a misunderstanding of what "confess to one another" means; i.e. confessing privately to a brother / sis whom we've wronged.
An example of how this sort of thing gets out of hand (not the confessing I'm off that now). When I was in Ukraine I attended an American church on Sunday and a Ukrainian church on Wednesday.
I was interested in joining the praise and worship team b/c I play an instrument and the pastor told me, "not now, we have a problem with fornication between members of the praise team now."
Well to a lot of Christians that seems like fine what he did, but guess what; there was only 1 girl on the praise team so I then knew who 1 of the "fornicators" was as well as anyone else who wanted to join or for whatever reason he felt like letting that slip. I think far too often we err on the wrong side of protecting people and their reps (I'm not preaching down to anyone BTW this one is hard for me to get a hold on as well; the tongue is just such a wicked weapon). We always find excuses, even those who know this teaching will use facial gestures, hints, etc. as if that escapes the sin since it's not technically speech.
I challenge everyone, myself included, to go a week without saying something bad about someone else, even when you think it's necessary (yes not life and death or extreme financial hardship or child molestation stuff).
Keep track see if you can do it. If you can well mazel tov to you, now try to avoid when others tell you stuff like that. Try to say, "sorry I'm trying to avoid evil speech right now so I can't listen to you tell me what a blowhard that person is." I'll be trying too. If you haven't understood this verse from R'Shaul, you'll get it after a week for sure:
ὃ γὰρ κατεργάζομαι οὐ γινώσκω· οὐ γὰρ ὃ θέλω τοῦτο πράσσω, ἀλλʼ ὃ μισῶ τοῦτο ποιῶ.
טו "For that which I myself do, I don't even understand; for that which I desire not, I do; but that which I hate I do!"
Letter to the Kehal in Rome 7:15
(BTW he uses 3 different Greek words that I watered down to a simple "do ... do ... do" probably someone could do an interesting word study on those guys:
katergazomai - "do, achieve, accomplish, produce, create"
prasso - "do, bring about, accomplish something thru activity, behave a way"
poeio - "do, manufacture, produce" )
