As Jonathan Kay has observed, one of the basic features of the conspiratorial mindset is a deep belief in the hypercompetence of the evil cabal that runs the world. But the Calvinist believes that the Holy Spirit runs the world, and that the conspiracies that do exist to resist Him are to be considered on a spiritual level with the Keystone Kops. The Lord laughs; He holds them in derision.
He says it here, on his Blog and Mablog blog.
