Scanning the 3 billion channel wasteland that is TV last night, I stumbled upon EWTN's "Tolkien's The Lord of the Rings, A Catholic Worldview" hosted by Joseph Pierce.
You can catch the intro
here in the featured videos. Not sure if the entire program is available.
Anywho, the program made very 'airtight' arguments showing why Catholicism is stitched into every thread of LotR, such as the Ring being destroyed on March 25 (The historical day of the Feast of the Annunciation as well as the day Jesus dies on the Cross).
Not sure how true any of it was, and so figured I'd ask those of you who know.
