Sorry, Bill. As soon as I read God, Devil and Antichrist in an article that is not tongue-in-cheek, I stop reading. Where did you find this, some American Religious Nutter website?
I'm sorry to say there are perfect wackos running around who fear the devil in their daily lives. Most of us outgrow that myth along with the Tooth Fairy and Santa Claus, but not everyone. In fact, America is full of them. I had a lovely chat with a bunch of old college buddies just this last weekend, and every single one of us (8 at the table) had at least one religious fundamentalist loony in our immediate families. My uncle miraculously regained his hearing during a prayer service; he told the story with gusto. The problem is... he'd never lost his hearing. Didn't stop him from believing he'd been miraculously cured.
I don't know what we can do about people who spew so much hatred for other people. As long as organized religion is looked upon as a good and positive thing, weirdos like the author of this article have all sorts of support for believing in devils and hell and other medieval holdovers that really belong up on Mount Olympus with Zeus. I recently made the decision to join the ranks of the atheists who say, honestly, this is all made up! Can't we all just get along?
