Juxtaposing “ecumenism” and “jihad,” two words that many would consider strange and at odds with one another, 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. Documenting the spiritual and moral decay that has taken hold of modern society, Kreeft issues a wake-up call to all God-fearing Christians, 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 one another so that we can form an alliance to fight together to save Western civilization.
