Scott L. Smith is clearly enthusiastic about both _LotR_ and the Eucharist. Alas, he drives it too hard. The idea of _lembas_ as being a type of the Eucharistic host is perfectly reasonable, as are a number of his other ideas. Similarly, I like his schema of three Christ figures - Frodo as Christ the Victim, Aragorn as Christ the King, and Gandalf as Christ the Prophet.
But he also leaps to some very strange conclusions. The strangest thing to me his his conclusion that there is a Virgin Mary figure associated with each of these. Arwen as the Bride of the King, yeah, okay, maybe. Galadriel who tends Gandalf after his death, well, maybe, but I have my doubts. But, and I quote:
"Frodo to Eowyn, a sword shall pierce your heart, as well, both wounded by Nazgul's" [sic].
Ummm...no. There is almost no relationship between Frodo and Eowyn whatsowhoever. She certainly is not any kind of mother or bride figure to him. And her heart is never "pierced"; it's Frodo's heart that was in danger of being pierced by the fragment of the Morgul-blade. He is right, at least, that Eowyn fulfills a prophecy; but not the kind that Mary fulfills by any means.
I could have accepted this as a reasonable area for disagreement, along with some other thoughts -- though it is clear that his understanging of _LotR_ comes at least as much from Peter Jackson as from JRRT; and though the book is full of poor editing work like the example noted above. All that I could have taken at least seriously.
But then he throws in a bonus section at the end, titled "The Catholic Theology of Star Wars".
No. Just...NO.
And, as if this were not silly enough, he manages to miss the semicanonic derivation of Jedi from "Jeremiah, Ezekial, Daniel, Isaiah". (I say "semicanonical" because there are other theories, some probably more plausible, but none of them has been confirmed by George Lucas either -- and while "Jedi" belongs to the Mouse now, Lucas would be the authority on where the words and names from the classic trilogy -- and the one whose existence I deny -- came from.)
So I'm afraid I cannot recommend this book. A pity, as there is a good book to be written on the subject. But this ain't it.
