Training Pastors: a proposal for theological colleges

Maybe there should be a rule that the average age of Faculty members at the theological seminary should not be less than 50. And maybe the majority should have been incumbents or senior pastors. I wonder how this would affect formation for ministry?

Oh, and maybe all pastors should be 30 before they are ordained. 

As a friend pointed out on Twitter, of course, the Lord Jesus Christ "trained pastors" when he was only 30. He would have pulled down the faculty average!
