This is what he says:
"Jesus refers to himself as the ‘bread of life’, ‘the good shepherd’, ‘the way the truth and the life’ and several other ‘I am the…’ examples. These were/are instructional as to how Jesus is capable of meeting our needs. We humans sure need a lot of explanations and examples.
John 4:13 (Jesus and the Samaritan woman) "Jesus answered, ‘Everyone who drinks this water will be thristy again, but whoever drinks the water I give him will never thirst. Indeed, the water I give him will become in him a sping of water welling up to eternal life.’"
John 6:35 “Then Jesus declared, ‘I am the bread of life. He who comes to me will never go hungry, and he who believed in me will never be thirsty.’”
Here Jesus is giving us spiritual bread, a relationship with him feed and nourishes our spiritual hunger. You have to take the body and blood of the last supper (which was actually Passover) in context. You have to understand what Passover represented. To demand an either or answer is really missing the entire point, by choice.
As to “God could change the bread and juice/wine if he wanted to” is silly. Of course he could. What you have to ask yourself is what would be the point? Would that action be in keeping with the nature of God. Personally, I say no, communion is not the actual body and blood of Christ. Leviticus prohibits eating/drinking blood because it contains life. A better question is ‘what is the purpose of communion?’ It it a time of rememberance of what Christ did for us. He willingly submitted himself to death on a cross. His blood had to be shed (as in the Jewish sacrificial passover lamb) in atonement for our sins."
I am gathering information myself to respond to this, but if you have anything to add, please do.
