Out of a “perfect storm” that seemed to promise only perfect destruction came God’s new creation in Christ, because the “hurricane that is God” was “reconciling the world to himself in Christ.” The realist-fiction writer Flannery O’Connor would simply call this unexpected return for violence “grace,” while the imaginative high-fantasy writer J.R.R. Tolkien would, true to character, linguistically embellish that “sudden and miraculous grace” as a “euchatastrophe,” compellingly combining the blessed word “eucharist” (to give thanks) with the cursed word “catastrophe.”
