It's almost embarrassing how little attention is paid to Tolkien's faith and how it shaped his fiction. The only ones who seem to pay more than a passing nod to it are Christian readers of Tolkien.
And as far as I know (haven't seen it), the recent biopic didn't help matters much.
Reading Tolkien/LOTR without a conscious awareness of how #Christ permeates every page is like kissing the bride with the veil still on.
