Could you please explain that last post a bit more? I haven't noticed any references, however subtle, to Christ in Tolkien's works, certainly nothing to let others come to know Christ.
Eru and the Valar in Tolkien's world are essentially gods, but their existence is never doubted and is documented as exact history. There is only one basic version of the story of creation in Arda, due to the fact that the early days, and the gods, were witnessed by some Elves, who were of course immortal. This is in contrast with the religions of our world.
Although Tolkien was a devout Catholic, it is debatable whether he intended his world to contain any religion in the true sense of the world, because all the creation stories he wrote were presented as factually as any others. After all, the main reason that he disliked the Arthurian mythology was that
It is involved in, and explicitly contains, the Christian Religion
I personally am not at all religious, simply because there is no proof of the fundament of the majority of religious beliefs. There is no element of doubt on the part of anyone, in Tolkiens stories, regarding the creation of the world and such.
Specific inclusion or reference to any known religion in his works would have greatly lessened their appeal to those not of that persuasion, be it Catholicism or any other.
If you can provide some background information, however, I shall be willing to reconsider my opinion.
