Perhaps I should note that I *don't* think I make moral decisions as independant of the bible; nor does that seem to me to be what Greta's arguing. Her argument, as far as I can see, is that the morality of the Christians she knows is based upon principles of love, fairness, compassion, etc, and that the fact that they feel they get it from God (which for most Christians DOES include the bible, which she doesn't even mention here) unfortunately doesn't mean the morality is any less moral.

Bron's right. You operate on a binary system, whereby one is either a biblical literalist, or one cannot use the bible at all.
