Recently I was reading through the Constitution and Bylaws of John Piper's church, Bethlehem Baptist in Minneapolis (can be accessed here: http://www.hopeingod.org/ConstitutionByLaws.aspx). I was interested to note that every elder must be reaffirmed by the congregation every three years. I have never been a part of a church that has a regularly scheduled vote of confidence or vote of reaffirmation in its pastor(s) or elders.
What do you think about this practice? Does your church do it?
