Pastor or Teacher?

I observed, as an outsider and a guest, a congregational voters’ meeting that was trying to decide whether to call as their school’s principal a pastor or a teacher. Strangely missing from the discussion was the doctrine of vocation. A member asked me to blog about this, so as to solicit my readers’ famous insights.

An earlier version of this post gave my views, but I decided to cut them out for now. What do you think? In light of the doctrine of vocation, what is a pastor called (and equipped) to do? What is a principal called (and equipped) to do? How would you vote on whether to call a pastor or a teacher to be principal of your parochial school?
