It is critical for our society that we get this normative debate right, for the stakes are high. We face increasing religious diversity. Liberal theorists, like Rawls, say that unless we keep religious reasons out of the public sphere, we could descend into a religiously motivated civil war similar to the Thirty Years’ War of the sixteenth century. On the other hand, critics of liberal theorists, like religious ethicist Charles Mathewes, say that unless we allow each other to talk about our deep differences, such as our religious beliefs, we could descend into the same nightmare that concerns the liberal theorists.
