Ah yes. Crap.
So you sent that to a "friend" and they proceeded to rat you out post haste. I don't know much but see two-three options.
1) Its yours. You were experimenting with a few things and just putting something on paper. Meant to be harmless, you shared it in confidence with a friend. You really are just "confused", and maybe you shouldn't serve anymore.
2) Deny it was yours and say you lied about it being yours to try to get your friends opinion about it. (this option requires lying so don't do it if you aren't prepared for it). You can come up with an explanation why.
3) Own it, test them on it, try not to get DF'd, but be prepared to be.
Eden the elders from my old congregations leave me alone even though they know more than they should about how I feel directly from me. I made several errors. They really COULD come and get me. But they leave me alone. Why? Its alot of work to deal with me, and I stayed away from the guys that like that kind of work. They were outmatched scripturally when dealing with me and because i knew their intent I knew what to say and not say. When they said, "What do you think about the role of the GB?", I turned to matthew and read where all authority in heaven and on earth had been given to jesus. I just pointed to it, and said, thats what I think, beyond that I'd just be giving my opinion, and I try to avoid doing that."
These guys talking to me were heavies. They were really looking, but I just handled it a certain way. Plus I was a good guy in the hall and area. i think if they really went there, it would have cast aspersions on their motives. So they leave me alone because its too much work. Maybe that is an avenue to try, if they really give you the business.
