Many times we are working with church structures of a different time. I have seen churches with 50 people attending on Sunday morning, and they maintain 12 committees. There may have been a lot of retirees in the church, so we have committees who meet in the day. Or there might have been a lot of people without children, so everyone meets at night—on a different night, to ensure that the pastor is at every meeting.
Many of the recent articles about clergy burnout suggested that it's a symptom of cognitive dissonance: pastors think their job ought to be a particular kind of work and are frustrated when it ends up involving something else. None of the media coverage, however, offered a compelling description of the call to ministry itself.
