Pharyngula tells us some scary stuff:
The program was called “Faith Matters”, and it’s not clear whether Nightline was going for high irony or was sincere. It’s about the Justice House of Prayer, an anti-abortion group whose strategy was to rent an apartment with windows facing roughly in the direction of the Supreme Court, where “interns” jump up and down and rant and pray towards the Court, apparently under the impression that they will have some psychic influence on the justices, or that their all-powerful god requires constant nudging and needs to be aimed in the right physical direction to have an effect. I get the idea they imagine their god as a vast, logy blimp without much consciousness, and if only they tug on his supernatural guidewires enough, they can position him over the court building—at which time he’ll reach down with fat, bloated fingers and diddle about in the brains of the people below him. It’s a strange, primitive theology, cult-like and absurd.
NewMexiKen isn’t quite certain how this kind of “prayer” is any less effective than any other kind, but it’s certainly more open to ridicule.
