The creature body that Jesus took tot he cross had the life of it carried by the blood He shed for our redemption.
The resurrected body JESUS now occupies no longer has blood carrying the creature life in it. GOD has another way of distributing The Life of the glorified ones throughout their real physical bodies, so the Jesus who catholiciism claims their priests bring down to their altars would not be a body possessing blood for them to consume! There is no continuing sacrifice of Jesus's body and blood because it is no longer a creature body He occupies.
There is no real presence of the Lord Christ in the lie that is the Catholic Mass. BUT Jesus himself told us that where two or more belivers / faithers in Him are gathered in His name, He is there in the midst of them. He is not there to be continually sacrificed in creature body. He is there in a spacetime reality we are not yet equipped to sense. But He is there ... The Lord Christ does not err and He keeps His Promises.
It was meant to confirm Jesus' own statement that where two or more were gathered together in His name He would be present with them. There was also the issue of arguing against the Gnostics/Docetists who denied Jesus HAD a flesh and blood body. The RCs seem to always leave that out of their discussion and I think the context of why terms were used is important.
One last thing is that these repetitive threads - meant, I think, to propose ONLY the Catholics have it "right" about this subject - seem to leave out the fact that there is no evidence for centuries that the Lord's Supper ordinance was seen as an "offering/sacrifice" or was meant to be for the expiation of sins with consumption being necessary for salvation. When Jesus said, "Verily, verily, I say unto you, Except ye eat the flesh of the Son of man, and drink his blood, ye have no life in you. (John 6:52), it was AFTER he had told them:
It has ALWAYS been about faith, believing in Jesus Christ and what He has done for us in saving us from our sins and enabling us to be in heaven with Him. Eating the bread and drinking the wine of the observance of the Lord's Supper is a testimony to the faith we already have and to remind us always of His sacrifice for us. Catholics sure don't have the copyright on that!
