I don't know all of them by a long shot, but one prominent Christian philosopher was C.S. Lewis. He also wrote a lot of other work, both fiction and non-fiction. His writing is excellent, and even some of his fiction has Christian philosophy thrown in in an interesting way. One of these, _Till We Have Faces_, is a story of a woman who writes a complaint to the Gods... and the story of her life and the answer that the Gods give. :) Another fictional work, _The Great Divorce_ talks about people who take a bus ride from Hell to look at Heaven and see if they want to go there. :) I recommend his work highly.
