I would just like to add that you need not be in a bethel elders department for him to counsel you. You can easily be counseled by your table head, foot, home overseer, adjacent department overseer, and even if a bethel elder sees you goofing off in the locker room he can counsel you whether he know you or not. All he has to do is ask your name and the rest is easy.
They don't have power in the sense of kicking out anyone they choose or making doctrine but they controlled the young boys (19+) that work so hard and play so unscripturally at bethel. These older men will still be expected to keep the youngsters in line -title or not.
