Muze,* take a closer look at John 6.* Jesus says in verse 53 that,* “I am the bread which came down from heaven, not as manna your fathers did eat and are dead; he that eateth this bread shall live forever.”
And in verse 49, “I am the bread of life.”
Now look at the comparison that Christ makes between the manna, which is a real food that the Jewish fathers ate in the desert, and another bread–His flesh.* This is called a ‘typology’.
The rule in understanding biblical topologies is that the fulfillment of a type is always greater than the type itself.
An example of this is when the apostle Paul compares Adam to Christ in 1 cor. 15:45-47, where he calls the first Adam, “a living soul,” and “earthly” to the new Adam who is a “quickening spirit” and “heavenly”.** Jesus who is the second Adam, is greater than the first Adam.
Another typology exists between baptism and circumcision, where in Col.* 2:11, Paul calls baptism the “circumcision of Christ”.** Again, where according to the old law, circumcision brought one into covenant relationship with God, baptism is the perfection of that rite by truly making one God’s child.
So where both Adams are men, and both circumcision and baptism are sacramental rites, when Christ spoke both of manna from heaven, and His own flesh, He very purposely meant His flesh to be thought of as real food.* If He hadn’t wanted to point to His own flesh as true food, or true drink, then He would not have brought to mind the manna in the wilderness to the attention of the crowd surrounding Him as the typology He was fulfilling by the “devouring” (Trogos in the Greek) of His own flesh, because the comparison would have been too gruesome if He really didn’t mean it.* While this isn’t as apparent in English, the context of the verse in Greek doesn’t allow for any other interpretation.* Trust me on this.* That is why John mentions the grumbling and the comment from the crowd, “this is a hard saying.* Who can hear it?”
To add confidence to this interpretation please read Paul’s first epistle to the Corinthians, chapter 11,* specifically verse 29,* “for he that eateth and drinketh unworthily,* eateth and drinketh judgment unto himself: not discerning the body of Christ”.
Consider something else.* The feeding of the five thousand, curiously occurring just prior to the events in John 6, was also a type of Eucharistic foreshadowing.* When He blessed the loaves and fishes, did the accidents of bread or fish change?* No, of course not or the people wouldn’t have eaten it.* But the loaves and fishes did change in one way–by increasing.* So if the accidents didn’t change, since fish can’t be more “fishy” or loaves can’t be more, well “loavy” --what did?* The matter did.* And in the same way, Christ shows us that in the Eucharist–where the accidents don’t change, nevertheless does change in its nature, by becoming the body and blood of Christ, just as Paul states in his first Corinthian epistle.
And once again consider the apostolic fathers like Ignatius, Clement, and Polycarp.* Both Polycarp and Ignatius were direct disciples of John the Evangelist, and so the meaning of John 6 was quite clear to them.** Remember again that as Ignatius was being escorted back to Rome for not paying tribute to Caesar, to be martyred for the faith in a macabre display of death from a pack of lions purposefully starved for a week before being loosed on him, he took the time to write an epistle to the Smyrnians, declaring the Eucharist to be the true flesh of Christ, and heretics were those who didn’t believe it.* If He lied about what John himself told him concerning John 6, then he was willing to be killed for it, and so were the rest of apostolic fathers for the same reasons.* And It doesn’t make sense that he was just wrong about his understanding of John 6.* One doesn’t die for something he isn’t convinced of.* And Ignatius was not a casual Christian.
But do I expect you to buy any of this?* Not really.* Because more than suffering the truth, you would rather suffer the defect of pride, and forego legitimate reasons to believe in a Catholic doctrine.** And I know about this because I suffer from the same.* I don’t like to lose arguments either.* But listening to more enlightened arguments as many of the posters have submitted here I think is the start of a wiser response from you than some of the ones you’ve been writing.
God bless.
