What I have on this comes from an experience from the late 60/early 70 time frame. There was a Circuit Overseer who came to OKla City area circuit who was of the "anointed". The only problem was that I do not believe he was over about 35 at the time. I am not going to mention him by more than initials (DW) because he was my friend and what I have to say is not totally complimentary. Everyone was of course fascinated by this abberation of the two class doctrine. Yes, we all knew it did not fit the 1931-1935 hypothesis, declining numbers at memorial, etc. So, there was a lot of buzz. This was before the elder thing, and I was out in a small congregation as assistant cong servant. My cong servant (a pretty sincere special pioneer) and I did a full gossip analysis on it. We were basically going on the party line that an old annointed must have done the unforgivable sin. Finally (believe it or not) the annointed CO sort of had a pi*zing match with this special pioneer's wife (because she was teasing me for wearing a cowboy hat during weekday service on a day about 15F in the sun) and I was left in the middle. (He made her cry and they went off by themselves to knock doors elsewhere.) Here was my chance, so I go for the question. What I got told was that "(bzz-bzz-) we cannot really say what JHVHs will is (garble-crackle-fade) but that it does not mean they were better than anyone else (crackle-pop) and that it does not give special insight unless we were on the GB itself (sweesh-burble-weird whistle sounds) (oops, we are losing the line...bzzzzzclick)". Now I am telling you all straight that this guy was a pretty good friend with me and would give me the real word on just about anything else, committee business and all. To this day he was certainly one of only TWO CO's that I found I could actually talk to. Probably I should mention that this annointed CO's wife was a really nice lady but was NOT of the annointed.
Well, of course he got reassigned in due time, went on I think to DO, and I went on to elder, quit in 1980 etc. I have asked several times and got told that after he and wife had a late-life son that he decided he wanted to be on the earth after all with the family and sort of UN-anointed himself. But all of that part is second hand. Maybe he is out there somewhere on this web and can laugh at my story for himself.
Bottom line: IMO this two class thing is elite-ism garbage and is not only unscriptural but unchristian as well.
