Here is a link to some fascinating new research on the increased incidence of second-career pastoral leadership, particularly in conservative protestant denominations. It appears that pastors are starting older and that they usually have had a career before they come into ministry. In general, I find this trend encouraging. Pastors with real life experience ought to do a better job of relating to the people that they preach to and serve. Check out the numbers and graphs at Pulpit and Pew.
