As a Roman Catholic, I always notice similarities between the Bible and Tolkien, who was a Catholic too. It is pretty cool sometimes. And if I recall correctly, C.S. Lewis was an atheist, but studied Christianity, and Christianity is the #1 parallel of his works, The Chronicles of Narnia.
Anyway, raised Catholic, but I dont think I have to go to church every Sunday. I love God... but I would not say no to an afternoon spent listening to Zeppelin in bed.
Either way, I do think that Tolkien has influenced the strength of my faith in God. The way he tells his stories and the way that he lived his life are definitely a model for me.
