You said -- "I thought it meant someone like Eric Rudolph, who'd blow up innocent people in the name of God."
Naaahhh..., that's more of a Catholic Tradition (maybe more historical now, however), who liked to persecute and kill other Christians. I think Eric Rudolph was reading too much into his own Catholic traditions. He should have stuck with Evangelical (historic and true) Christianity.

You might want to further elaborate this comment....considering what the Anglican British did to Catholics in both England and Ireland and Scotland, for just one example.
