Thanks.  With your comment I am thinking it would be a really good idea to research the allegory or the Ring, and the watch or re-watch Lord of the Rings with you son so he will understand the meaning behind the story.  There is also a Christian message in all Tolkien's stories.  C.S. Lewis was a close friend of Tolkien.  Lewis has been credited with motivating Tolkien to finish is Ring books, and Tolkien is the one who influenced Lewis, a devout atheist, to becoming a christian.  The book Lewis novel Chronicles of Narnia is full of christian symbolism. Did you ever read Mere Christianity by C.S. Lewis?  It, I think, is a look at Christianity from a rational prospective.  The first part, The Law of Nature as a Clue to the Meaning of the Universe the well reasoned explanation  of the proof that outside influence exist.  It is not a Thumper book at all, but just lays out some principles in a logical way. Here you can read the chapters or listen to the audio which is excellent.
