Fine. I'm a literary incompetent. It has just now hit me (thirty years after reading it for the first time) that George Orwell's 1984 is a straightforward religious allegory.
Big Brother is God, the Inner Party the priesthood, the Proletariat the unquestioning, uncritical sheep, and the Outer Party the visible expression of the innate sinfulness of humanity. "Reason is a whore" and the enemy of religious truth, and the perpetual job of the Inner Party/priesthood is to stamp out reason in favor of revealed truth.
