Brian Hines' blog "Church of the Churchless" expounds very well the viewpoint of a post-Christian naturalist.
His latest post "Evolution shows the grandeur of life" is, in my opinion, a beautiful statement of Religious Naturalism (although he has never identified himself as such). This simple sentence says it all:
"I've been reading a few pages [of Richard Dawkins' latest book The Greatest Show on Earth] every day before I meditate. Now, I find more inspiration in science books than in spiritual books. Reality is uplifting."
