Book excerpt: Juxtaposing "ecumenism" and "jihad", two words that many would consider strange and at odds with each other, Peter Kreeft argues that we need to change our current categories and alignments. We need to realize that we are at war and that the sides have changed radically: many of our former enemies (e.g. Muslims) are now our friends, and some of our former friends (e.g. humanists) are now our enemies. Documenting the spiritual and moral decay that has taken hold of modern society, Kreeft issues a wake-up call to all God-fearing Christian, Jews and Muslims to unite together in a "religious war" against the common enemy of godless secular humanism, materialism and immorality. Aware of the deep theological differences of these monotheistic faiths, Kreeft calls for a moratorium on our polemics against each other so that we can form an alliance to fight together to save western civilization. He cites numerous examples of today's Protestants, Jews, Catholics and Muslims working together to solve moral and spiritual problems. God is calling for this unity, Kreeft says, and if we respond, God will do something wonderful.
