Well, Burgos has a point. If you accept the Bible as at least "containing" the word of God or reflecting the "inspiration" of humanitys' encounter with the Divine, you can't really pick and choose based on convenience or the current fashion. The only way to escape the parts you don't like is to deny that the Bible is anything but a human creation. That's basically the approach some liberal rabbis take. The problem with that is that once you say that Torah is a strictly human creation there's no authority beyond human tradition to govern human actions. The problem with THAT is there's no objective morality AT ALL because there's no natural law. The law is whatever the guy with the biggest stick says it is. After the Twentieth Century this idea is a lot less attractive than it might have been in 1910. Everyone patient enough over the years to read my posts here knows that I am a Positivist in most things. But pure Positivism must somehow be accountable to basic decency or being human has no meaning. Actually, there is a third way and that's to claim current revelation. Any such claim of revelation will rightly attract the most searching scrutiny.
