Pork,Cat, I don’t want to put words in your mouth but as you believe Christ was only speaking symbolically and you disagree with the Catholic and Orthodox interpretation of v63, how do you account for the disciples going out and preaching that it was his actual body and blood present in the Eucharist? Was Jesus a very bad teacher or were the 12 disciples hard of hearing?
Below are some quotes from the very early church fathers. There are many more ECF quotes than this as well as scripture passages. A good website is scripturecatholic.com. We’re straying off topic so I’ll let you have the last word but I would appreciate hearing your response to the above question(s). God bless!
They abstain from the Eucharist and from prayer, because they confess not the Eucharist to be the flesh of our Saviour Jesus Christ, which suffered for our sins, and which the Father, of His goodness, raised up again." Ignatius of Antioch, Epistle to Smyrnaeans, 7,1 (c. A.D. 110).
“For not as common bread and common drink do we receive these; but in like manner as Jesus Christ our Saviour, having been made flesh and blood for our salvation, so likewise have we been taught that the food which is blessed by the prayer of His word, and from which our blood and flesh by transmutation are nourished, is the flesh and blood of that Jesus who was made flesh.” Justin Martyr, First Apology, 66 (c. A.D. 110-165).
“[T]he bread over which thanks have been given is the body of their Lord, and the cup His blood…” Irenaeus, Against Heresies, IV:18,4 (c. A.D. 200).
“He acknowledged the cup (which is a part of the creation) as his own blood, from which he bedews our blood; and the bread (also a part of creation) he affirmed to be his own body, from which he gives increase to our bodies.” Irenaeus, Against Heresies, V:2,2 (c. A.D. 200).
“But what consistency is there in those who hold that the bread over which thanks have been given is the Body of their Lord, and the cup His Blood, if they do not acknowledge that He is the Son of the Creator of the world…” Irenaeus, Against Heresies, IV:18, 2 (c. A.D. 200).
“For the blood of the grape–that is, the Word–desired to be mixed with water, as His blood is mingled with salvation. And the blood of the Lord is twofold. For there is the blood of His flesh, by which we are redeemed from corruption; and the spiritual, that by which we are anointed. And to drink the blood of Jesus, is to become partaker of the Lord’s immortality; the Spirit being the energetic principle of the Word, as blood is of flesh. Accordingly, as wine is blended with water, so is the Spirit with man. And the one, the mixture of wine and water, nourishes to faith; while the other, the Spirit, conducts to immortality. And the mixture of both–of the water and of the Word–is called Eucharist, renowned and glorious grace; and they who by faith partake of it are sanctified both in body and soul.” Clement of Alexandria, The Instructor, 2 (ante A.D. 202).
“Then, having taken the bread and given it to His disciples, He made it His own body, by saying, ‘This is my body,’ that is, the figure of my body. A figure, however, there could not have been, unless there were first a veritable body…He did not understand how ancient was this figure of the body of Christ, who said Himself by Jeremiah: ‘I was like a lamb or an ox that is brought to the slaughter, and I knew not that they devised a device against me, saying, Let us cast the tree upon His bread,’ which means, of course, the cross upon His body. And thus, casting light, as He always did, upon the ancient prophecies, He declared plainly enough what He meant by the bread, when He called the bread His own body. He likewise, when mentioning the cup and making the new testament to be sealed ‘in His blood,’ affirms the reality of His body. For no blood can belong to a body which is not a body of flesh. If any sort of body were presented to our view, which is not one of flesh, not being fleshly, it would not possess blood. Thus, from the evidence of the flesh, we get a proof of the body, and a proof of the flesh from the evidence of the blood.” Tertullian, Against Marcion, 40 (A.D. 212).
With your permission, here is what Luther said about the ECF’s and the real presence.
JonWho, but the devil, has granted such license of wresting the words of the holy Scripture? Who ever read in the Scriptures, that my body is the same as the sign of my body? or, that is is the same as it signifies? What language in the world ever spoke so? It is only then the devil, that imposes upon us by these fanatical men. Not one of the Fathers of the Church, though so numerous, ever spoke as the Sacramentarians: not one of them ever said, It is only bread and wine; or, the body and blood of Christ is not there present.
Surely, it is not credible, nor possible, since they often speak, and repeat their sentiments, that they should never (if they thought so) not so much as once, say, or let slip these words: It is bread only; or the body of Christ is not there, especially it being of great importance, that men should not be deceived. Certainly, in so many Fathers, and in so many writings, the negative might at least be found in one of them, had they thought the body and blood of Christ were not really present: but they are all of them unanimous.”
This implies to me, that Jesus was an extremely poor teacher on a subject that was foreshadowed in the OT, explained clearly in Jesus’ own words and believed not only in the early church as “real” food but also up to and through the reformation (with Luther’s altered real presence belief included…). A symbolic only understanding is a fine example of a man made tradition(s), reading the bible through a set of preconceived beliefs.
