I suppose I don't see a real difference between what we believe about God and what we believe is essential. Or maybe I'm just missing the distinction. It isn't possible to approach the subject without conceptualizing...but what I'm suggesting is that the investment of faith and trust must be in a concept of God that allows for our ignorance of particulars, must recognize our inability to encompass and judge, so that when something comes that we cannot reconcile in the moment we rest, not on our particular understanding, but on our broader investment of trust and understanding of our inescapable limitations. The fault, where there is fault, must be in ourselves and doubt, should doubt enter, is then rightly placed in our particular understanding.
