I was still fully involved, a recently appointed elder, when I had to move away from my original congregation and relocate. I went to my mother's congregation for awhile as an in-between situation, so they knew I wasn't going to be there for more than 6 to 9 months. They asked me if I would take on some elder assignments and I said "Sure."
The elder sent to ask me said there was one problem. "Our elder body doesn't allow mustaches." I pictured these men and none of them had a mustache. After a brief pause, I said "Perhaps I better not serve with your elder body." He paused longer than a short while and said "I am just kidding, your mustache will be fine."
But he may not have been kidding. I think they really didn't like mustaches, and hoped I would shave it. But I think he was instructed to say that he was kidding so that I wouldn't say anything to the C.O. if I balked at their policy.
