mmm, again about Bible...
There is more just the dates of the departure of the fellowship and the downfall of Sauron (They were really chosen by Tolkien) and Gandalf's reversion...
You can't really feel that, but Christianity is all around LOTR and Silmarillion. For exapmle take Galadriel. She is symbolic figure of mother in LOTR. I don't think about her personal deems and experiences (she is not very perfect lady at all
, but for The Fellowship and specially for Frodo she seems like one. She gives advices and take care of them. I guess, she feels that and finds out for herself, when she passes on the Ring. She is similar with Varda in Silmarillion. In LOTR Galadriel takes her place.
O, and you can't forget that Tolkien had made real religion. Iluvatar and valar and maiar... what more?
