CUP:
1. A small open container, usually with a flat bottom and a handle, used for drinking.
2. Such a container AND its contents.

No changing back and forth:

There was wine, it was poured into a cup, and turned into the blood of Christ. As the blood of Christ, it is still the "fruit of the vine," every bit as much as wine is the fruit of the vine, because it was made from the vine. (In the same sense, Jesus is the fruit of Mary's womb.)

[Havoc]

If it turned into the blood of Christ, why then is it still wine? It doesn't say he won't drink his own blood, it says he won't drink the fruit of the vine again till later - fruit of the vine is wine for those in rio linda. Again, ignoring what you want in order to fit into your philosophy rather than taking the whole and gleaning the proper understanding given in scripture.

You're clergy were trying to understand with their physical minds just as the pharisees and saducees did. Just as the unbelievers did. And they were caught in the same trap that Christ layed for the unbelievers. That's what He intended and that's wherein you are snared. And that is where you will remain snared unless God opens your spiritual eyes. John 6 provides a great wealth of clues to what Christ is saying along with abundant allusions to the OT to references which spell it out in no uncertain terms.
Those ignorant of God's word just run right on by it, ignore it and don't get it. I'll lay it out there for the others again. If the BREAD OF LIFE was being eaten in the OT by listening to and acting on the words of God, it is the same yesterday today and forever, then how does the bread allof a sudden require injesting food rather than listening to God's word? Christ states that hasn't changed even in John6 - It is the work of God that you should believe him whom he sent, etc. Have fun.
