Given recent work in quantum physics suggesting that our world is just one world in a series of many, Leland Royce Harper calls for a shift in our concept of the monotheistic God of Judeo-Christian tradition. In Multiverse Deism: Shifting Perspectives of God and the World, Harper argues that those who wish to maintain that the Judeo-Christian God exists ought to revise how they define this God and what they expect of Him so as to maintain consistency between modern theism and the growing body of scientific knowledge. While this revision entails several concessions by the theist, the overall result is a stronger and more coherent account of who God really is. By removing the expectation that God will act in the natural world, Harper argues that we are left with a concept of God that maintains all of the traditional divine attributes, is consistent with current scientific advances, remains compatible with contemporary and historical arguments for the existence of God, and better refutes contemporary and historical arguments for atheism than the traditional, active God.
