I do not think that it is right to turn to cultural anthropologies in order to either affirm or negate a doctrine. Human experience is not the criteria of biblical doctrine. For instance, there have been cultures where people lived nude, without any covering whatsoever, and felt no sense of shame–that doesn’t falsify the Genesis account in which Adam and Eve felt ashamed that they were naked, after the Fall. There have been certain cultures where cannibalism was practiced and people ate their neighbors–that doesn’t become an experiential argument for the ethical innocence of cannibalism. I think we must be careful not to bring in the experience of man in a culture to validate or invalidate a biblical doctrine.
