Killing the pastor

Do we only want pastors and teachers? What about evangelists, apostles, prophets? Or are people with these gifts too scary to have in the average church? Won't the evangelists be forever telling us to get out and evangelise? Won't the apostles be demanding we start up a new church every five minutes? Won't the prophets come to church dressed in weird garb and shouting loudly?
Len, on the New Reformation blog, has written:
Alan Roxburgh and others argue that the sola pastora (single pastor) model of church has not only sapped the missional impulse from the church, it has cast many pastors into relative isolation. Roxburgh claims that this model, with its focus on one dominant, usually shepherd-type leader, is “killing pastors,” leading to “terrible discouragement and loneliness, and creating a deep sense of personal failure.”
He goes on to discuss this issue, but I want just to mention that wellness in ministers these days is one of the great plagues of society, far worse than swine-flu, far worse than any pandemic we've supposedly known in recent decades. We have to change. Churches have to take responsibility for leadership, not just leave it all to one over-burdened man.
