the bible is fiction and theology is literary criticism. As literature, the bible is not really designed to empirically explain anything but rather to give form to our internal lives in the context of the world in which we live. Unfortunately, since it's The Bible revisions to accurately reflect cultural changes have been erratic, spotty and occasionally violent. Probably because a lot of money and power depend on keeping it the way it is.
I think Charles' interpretation of christian faith is an effort to place God in the center of our modern understanding of causality. That understanding today is concerned with things like quantum mechanics, microbiology and other aspects of the natural world that are too small or remote to be directly percieved but nevertheless have an impact on our culture. It's a sort of "new agey" Christianity and if that works for him it's fine with me.
I think problems arise when revisions to Christian doctrine have more to to with effective marketing than spiritual enlightenment. Given the importance of religion and an interpretation of the nature of God in the exercise of power throughout human history, we should exercise special care and a healthy dose of skepticism regarding a new understanding of the divine. I find Charles conception of God unsatisfying because it seems to depend more on cultural changes for popular appeal than give a deeper insight into our understanding of our place within them.
