I have argued elsewhere (Fighting Words: The Origins of Religious Violence [2005]) that we need to treat ethics in biblical texts just as we treat ethics in any other works of ancient literature. It is a vacuous exercise to pick and choose which atrocities were really ordained by any gods and which were not. We should have a zero-tolerance view of any text or collection of texts that at any time endorses genocide, misogyny, and other atrocities. We always judge ancient texts by modern ethical standards, and the Bible should not be treated differently.

If everything must have a cause, of course, this also applies to God; if God can exist in isolation, then why not the universe?
