I just finished reading Kreeft’s Snakebite Letters—a follow up to C. S. Lewis’ Screwtape Letters. While reading this book you must remember it’s written from the perspective of a demon. That means “the Enemy” is God. We’re the ones who have forgotten.
We’ve also made them forget the old story that music was the language the Enemy used to create the world, was the language of Eden, and will be the language of Heaven, the universal language. We’ve also gotten them to forget the mystics’ favorite book, the Song of Songs, and even if they pay attention to it, they forget the title.
