For Tolkien, mythology touched the deepest part of our souls, and invites us to explore the beauty of creation and to discover and participate in the sacramental nature of life. Only in the True West could one find a proper understanding of order, virtue, and liberty. As Tolkien himself said, the mythology and purpose guiding The Lord of the Rings was nothing less than the return to Christendom. His Middle-earth mythology, he hoped, would serve as a wake-up call for the West, to return it to its pre-statist, pre-imperialist, pre-materialist phase. With the return of Aragorn the king, the “progress of the tale ends in what is far more like the re-establishment of an effective Holy Roman Empire with its seat in Rome,” Tolkien admitted in 1967.

Certainly Tolkien, as with most of the Augustinian Christian Humanists, had a Jacobite streak.
