Does this mean that absolute truth, good and evil and the sure hand of Providence are nowhere to be found in the Old Testament?
I don't see anything explicitly Christian in LOTR. Even the return of Elassar(Aragorn) to the throne of Gondor conforms more to the Judaic view of a human Messiah reclaiming the throne of David. The story itself contains many elements of Germanic, Norse and Celtic mythology but nothing explicitly Christian that I can identify. The romance (immortal woman chooses mortal lover and gives up immortality) is straight out of Die Walküre but not the Bible.
If Christians see a Christian message in LOTR, fine with me, but I wouldn't say that such a message is explicit.
There is nothing in LOTR that is specifically Christian; people are just reading it into the books
Incredibly,some Christians did the same thing with the Harry Potter books
