Per capita, we have more executions in our state than any other. Lest you dismiss demonology out of hand, consider that exorcism has not gone out of style. The pope himself performed one just last year. Anyone who encounters evil finds it anything but abstract. Think of the Holocaust, Kosovo or Chechnya, or even road rage.
Angels are fashionable.
As a child, I prized images of the Archangel Michael and St. George tussling with the dragon. Bring those images up to date and we have Buffy the Vampire Slayer, a teen-age heroine who not only knows evil when she sees it, but does something about it. Buffy made her first appearance in a film and is now in her fifth season on television. Calif. Unknown to most of its teachers, students and their parents, the school happens to sit over the mouth of hell and is subject to invasions by demons. But American Catholics especially appreciate the show's grasp on evil.
