The MRT and I were chatting through our homework for Isaiah class, and particularly going over our Brueggemann intro to Second Isaiah. She was distraught by an equation Brueggemann drew between Babylon and our modern consumer culture, and it took us a while to nail down why. Finally, it came down to the fact that we, as putative members of Brueggemann's Israel are also culpable in our exile. We were not captured - we have marched ourselves into captivity with shouts and singing. It does not necessarily change the responsibility of the Lord towards us - but it does mean that we cannot condemn Babylon with quite such vigor as the Israelites had some right to do - we took ourselves there.
