Following is my response to this topic on another board, and several comments here seem to agree in different verbage.
I can still remember when I was about 13, a local boy that was several years older than me was preaching in my church. He had obtained his degree from the seminary and was quite the intellectual.
The one thing that stands out for me was a closing comment while praying:
"And Lord, bless this, thy constituency ---"
My mind almost stripped gears as I stopped listening to figure what he had just said.
I always heard that the most educated (truly educated, not just a lot of book learning) could speak to so that the smartest would not be bored, yet the simplest could understand.
I think one could say that education that is "used" is fine, but that same education "flaunted" is an insult to God
