The way I see it is, hasn't Heaven always been reffered to as being above us, and Hell, below us. Well, we have been above us, and have learned a good deal about below us. There was no evidence of a Heaven, nor a Hell. So, then it changes. "It was just symbolism." I just have trouble believing something that can be taken literally one minute, then symbolic the next. That is however, my skewed perspective. I don't pretend to know about religious text.
