Its an older article (from 2007) and pretty lengthy, so I'm just posting the link instead of pasting it in. The article tells the story of several clergymen and their declining belief (and for most their eventual loss of belief). A really good read if you have a little while.
Dan Barker is actually one of the features in this article; and he comments on some of the correspondence he has had with doubting clergy.
And speaking of 'Dawkins' and 'no other skills'... A part in the article mentions that Dawkins "hopes one day to address it through 'clergyman-retraining scholarships,' set up through his charitable foundation, to "bridge the gap between living a lie and getting a new life.'"
