Preaching to "normal people"

Here is a three-part series (one, two, three) on "How Seminarians Can Learn to Preach to Normal People".

The questions arise...

... why in the West does the default method for training preachers require additional layers of instruction from bloggers in ... (drum-roll) ... how to preach?

And... what side of "normal" are seminarians? Why does the default mode of theological training for future pastors apparently lead them into becoming "non-normal", such that they require special instruction in how to deal with the ranks of the "normal"?

Good questions, are they not?

As well as learning from the helpful advice in that series, we should also take a step back and ask - why is this advice necessary at all? What are we doing wrong that has led us into this position? And, what do we intend to do about it?
