I thank you for your rep; however, I have to say that I was surprised by receiving it. I expected to receive a chorus of bored groans instead of questioning. Nothing that I have written is not self evident to a Catholic enthusiast of Tolkien-- in fact, I thought that the bit about the Lembas as eucharistic and Galadriel as Mary was known to just about everyone who has touched on Tolkien's Catholicism.
All these themes are touched on in Bradly Birzer's
"Sanctifying Myth" and Peter Kreeft's
"The Philosophy of Tolkien."
