Tolkien always maintained that neither the war, nor religion featured deliberately in his work and I see no reason to doubt him.
C. S. Lewis on the other hand meant his stories to have Christian themes, so subtlety or a lack thereof didn't enter into it.
I don't think that Tolkien denies Christian themes, rather he denies overt Christian symbols and allegories. Indeed, from what I have read he intended this work to develop a pre-christian world that was consistent in morality and belief with Christianity (in the same way Christians would hold that the Prophets of the old Testament held beliefs consistent with Christianity).
