I'm coming into this conversation as a newbie and Christian, rather late. As I Christian I was very drawn to the movie and later the books. I see both Christian values and a very conservative political theme running through the LOTR. Not to say that other faiths hold many of the same ethical values, but I saw a lot of "Bible" in there for lack of a better term off the top of my head. I read the Silmarillion, and in the first few pages I saw plenty.
I will refer you to a website that shows the similarities. I found it very much in line with what I was thinking.

I guess you will just have to put up with us Christians on these forums.
