“Spiritual warfare,” systematic demon-fighting, is another old Christian concept that had mostly faded away in America—until it revived in the 1960s and took off during the 1980s and ’90s. It is now the animating notion across a broad swath on the darker side of American Christianity. A spiritual warfare Protestant is an evangelical or charismatic who’s angry about something. They call their loud, belligerent prayers against Satan “violent intercession.”
