Pastoral Analogies

This weekend I began reading M. Craig Barnes' book The Pastor as Minor Prophet. (Hat Tip: Scot McKnight.) Which started me thinking about all the possible analogies for pastors. (i.e. pastor as ceo, pastor as family chaplain, pastor as teacher, etc.)

What analogies do you believe best describe the role of a pastor? If you are a pastor, in what analogous role(s) do you see yourself operating?

As part of my own journey I am trying to more clearly understand my call to pastoral ministry and the analogous role that best describes that call. At the same time I'm working to understand the analogous role that the congregation I serve both needs and wants in their pastor (which could be two different and sometimes opposing roles.)
