It's the interpretive process, Rn. The Lord in John 6 clearly says the "body/blood" words are "spirit." In other words, the Bible tells us to take them spiritually/symbolically/figuratively. That is the whole point.
Also, Hebrews clearly tells us the OT sacrifices were figurative. Again, we have the Bible telling us to view all animal sacrifices figuratively.
That's the whole point of the "literal" interpretation threads.....this thread.
You must find legitimate scripture/context for "symbolizing" anything. As long as you do, you're behaving fairly with the Bible. If you don't have scripture/context saying you can take it figuratively, then you are just placing your own opinion into a tough spot of scripture.
Also, thanks to all for the prayer earlier today. It was awesome!!
