Jack Posobiec has revived a scholarly argument about the paganism of Tolkien's work. It is not entirely a stupid argument. Posobiec (and del Arroz) should know, however, that this argument has already been had. The pagans lost.
Lord of the Rings is to be understood as Mel Gibson intended Apocalypto. This is a world before Christ, and before the Flood; a Hyborean age if you will (the canon Unwin maps even look similar to Howard's). Gibson's "Icon" production-company, in the Maya world, had a pregnant character appeal to a blessed Mother-Virgin. She does not know Mary, but she still knows deep down she intercedes.
As such, no Tolkien character can refer to Scripture - unless that Scripture be the Silmarillion. The characters can, however, prefigure Douay-Rheims and the Vulgate. Aragorn heals the sick of Gondor as will the secret Markan messiah. Samwise calls upon Elbereth to retrieve the elven rope. One can go on and on here: down to Mairon's presence as the twentieth-century war engineer, doing Melkor's will perhaps against his own instinct. (Mairon - Sauron - consciously had spread a Melkor cult in Anadûnê; but I suspect that from malice, because Númenor stood in Sauron's way.)
As to del Arroz, he has shifted to defending Posobiec from himself. My thought is that Vox Day needs to wrangle his 'tard.
