Are there any resources out there explaining how the VERY LIBERAL churches interpret the Bible?
You wish. :P
To further complicate matters--it's not really so much a liberal v. conservative issue. Roman Catholicism, for instance, would not be considered "liberal" by most (I'd think), although there are both (politically) liberal and conservative Catholics. RC doesn't read the bible literally (with some exceptions--and some mystical beliefs that extend beyond literal/figurative).
"Liberal" might include: Disciples of Christ, Episcopalian, (some) Methodist, (some) Presbyterian, Unitarian Universalist (not really Christian)...I'm sure many more, no expert.
Do you think your DS is more interested in the bible itself, or the nature of religious belief?
UU is a good place for an academic type of religious study. This would likely not go over well with your parents, though, so DS should keep it on the down-low if you go this route.
