Hello Meat Pie,
My wife and I went through this process seven weeks ago, where we had documented evidence about the UN Involvement, paedophilia, failed prophecies, alleged shares in warfare etc. But we started off the meeting by saying "we have serious doubts about the organisation ..", then after that we went into the heavy stuff. We were covering ourselves with the scripture in Jude v.22 "continue showing mercy to some that have doubts..."
Nothing has come of this four hour meeting, even though the two elders were given a personal set of all of our documents. Not even a phone call !
After hearing their excuses on all of these fronts, we quoted James 4:17.."Therefore if one knows how to do what is right and yet does not do it, it is a sin for him."
Also Lev. 5:1 "...now in case a soul sins in that he has heard public cursing and he is a witness or he has seen it or has come to know of it, if he does not REPORT it, then he must answer for his error" again we were answering from the scriptures in relation to UN etc.
