You have reminded me, U A, of what happened in our Congregation when the Elder thing was first brought in, only one guy accepted, and he was actually elderly, and one of the Anointed, the other "Servants" all felt they did not qualify ! This guy was a humble, really spiritual man, who cared for all.
When the C.O visited some months later, he persuaded the Servants that they were being too modest and self critical, so the P.O of the time, and a few others accepted. Others accepted in time.
I think, as in many other aspects, our guys were pretty unique in this, which made for a nice atmosphere in the Congregation, which caused many JW's over the years to move in from elsewhere. Nobody had a huge ego, until a young guy in his twenties, an Elder, moved in, he was different, a real by the Society Rule Book man, but constantly was restrained by the others.
