A Lack of Preachers?

[Esquilax]

Maybe it will help weed out all the fakers pretending to be clergy who are only in it for the money.

I still find it rather interesting that you seem so confident in your ability to divine the thoughts of people you don't know: I'd submit to you that at least a few preachers just think that god wanted them to become rich through their preaching. Ineffable plan, and all that.

It wouldn't be any more of an interpretation of convenience than any other theist's.
