“Liberal theory, however, doesn’t have to demonstrate the difference. It only has to show that moral decisions on matters of public policy in a pluralist and democratic state are satisfied, or justified, by a particular political test: the “ability to gain assent from people who retain radically diverse ideas about the point and meaning of human life, about the path to private perfection.”43 Appeals to the will of God through quoting the Bible, church doctrine, and ecclesiastical authorities, fail this test for public values because it isn’t clear how these appeals can be adjudicated.”
