Literature exploring religion as deeply as Pasolini does

I'm a big fan of how Pasolini discusses religion. I think he manages to find the perfect balance between 'coolness' (beauty) and substance (thoughts on the relation between religion and communism in "The Hawks and The Sparrows", for example) in his works. Since I also love to read, I really want to read something similar. Could anyone here recommend me some books that have the same characteristics : beautiful religion paired with deep thoughts ? I don't care if it's fantasy, science fiction, or classical literature, or even if it is Christianity.

Many thanks.
