John 6:30 begins a colloquy that took place in the synagogue at Capernaum. The Jews asked Jesus what sign he could perform so that they might believe in him. As a challenge, they noted that "our ancestors ate manna in the desert." Could Jesus top that? He told them the real bread from heaven comes from the Father. "Give us this bread always," they said. Jesus replied, "I am the bread of life; whoever comes to me will never hunger, and whoever believes in me will never thirst." At this point the Jews understood him to be speaking metaphorically.
Jesus first repeated what he said, then summarized: "‘I am the living bread which came down from heaven; if any one eats of this bread, he will live for ever; and the bread which I shall give for the life of the world is my flesh.’ The Jews then disputed among themselves, saying, ‘How can this man give us his flesh to eat?’" (John 6:51–52).
His listeners were stupefied because now they understood Jesus literally—and correctly. He again repeated his words, but with even greater emphasis, and introduced the statement about drinking his blood: "Truly, truly, I say to you, unless you eat the flesh of the Son of man and drink his blood, you have no life in you; he who eats my flesh and drinks my blood has eternal life, and I will raise him up at the last day. For my flesh is food indeed, and my blood is drink indeed. He who eats my flesh and drinks my blood abides in me, and I in him" (John 6:53–56).
Notice that Jesus made no attempt to soften what he said, no attempt to correct "misunderstandings," for there were none. Our Lord’s listeners understood him perfectly well. They no longer thought he was speaking metaphorically. If they had, if they mistook what he said, why no correction?
n John 6:60 we read: "Many of his disciples, when they heard it, said, ‘This is a hard saying; who can listen to it?’" These were his disciples, people used to his remarkable ways. He warned them not to think carnally, but spiritually: "It is the Spirit that gives life, the flesh is of no avail; the words that I have spoken to you are spirit and life" (John 6:63; cf. 1 Cor. 2:12–14).
But he knew some did not believe. (It is here, in the rejection of the Eucharist, that Judas fell away; look at John 6:64.) "After this, many of his disciples drew back and no longer went about with him" (John 6:66).
This is the only record we have of any of Christ’s followers forsaking him for purely doctrinal reasons.
But he did not correct these protesters. Twelve times he said he was the bread that came down from heaven; four times he said they would have "to eat my flesh and drink my blood." John 6 was an extended promise of what would be instituted at the Last Supper—and it was a promise that could not be more explicit. Or so it would seem to a Catholic.
John 6:63 It is the spirit that quickeneth; the flesh profiteth nothing: the words that I speak unto you, they are spirit, and they are life.
Are we to understand that Christ had just commanded his disciples to eat his flesh, then said their doing so would be pointless? Is that what "the flesh is of no avail" means? "Eat my flesh, but you’ll find it’s a waste of time"—is that what he was saying? Hardly.
The fact is that Christ’s flesh avails much! If it were of no avail, then the Son of God incarnated for no reason, he died for no reason, and he rose from the dead for no reason. Christ’s flesh profits us more than anyone else’s in the world. If it profits us nothing, so that the incarnation, death, and resurrection of Christ are of no avail, then "your faith is futile and you are still in your sins. Then those also who have fallen asleep in Christ have perished" (1 Cor. 15:17b–18).
In John 6:63 "flesh profits nothing" refers to mankind’s inclination to think using only what their natural human reason would tell them rather than what God would tell them. Thus in John 8:15–16 Jesus tells his opponents: "You judge according to the flesh, I judge no one. Yet even if I do judge, my judgment is true, for it is not I alone that judge, but I and he who sent me." So natural human judgment, unaided by God’s grace, is unreliable; but God’s judgment is always true.
In John 6:63 "flesh" does not refer to Christ’s own flesh—the context makes this clear—but to mankind’s inclination to think on a natural, human level. "The words I have spoken to you are spirit" does not mean "What I have just said is symbolic." The word "spirit" is never used that way in the Bible. The line means that what Christ has said will be understood only through faith; only by the power of the Spirit and the drawing of the Father (cf. John 6:37, 44–45, 65).
Paul wrote to the Corinthians: "The cup of blessing which we bless, is it not a participation in the blood of Christ? The bread which we break, is it not a participation in the body of Christ?" (1 Cor. 10:16). So when we receive Communion, we actually participate in the body and blood of Christ, not just eat symbols of them. Paul also said, "Therefore whoever eats the bread and drinks the cup of the Lord unworthily will have to answer for the body and blood of the Lord. . . . For any one who eats and drinks without discerning the body, eats and drinks judgment on himself" (1 Cor. 11:27, 29). "To answer for the body and blood" of someone meant to be guilty of a crime as serious as homicide. How could eating mere bread and wine "unworthily" be so serious? Paul’s comment makes sense only if the bread and wine became the real body and blood of Christ.
The early Church took John 6 literally. In fact, there is no record from the early centuries that implies Christians doubted the constant Catholic interpretation. There exists no document in which the literal interpretation is opposed and only the metaphorical accepted.

Just can’t get past that physical flesh thing can you. NO, He was explaining that it was spiritual not physical flesh.
With all due respect, Crazy Evangelicals disagree for good reason: the very early Jewish nature of the church which quickly switched over to a Gentile nature as the Jewish community officially soured on Christianity. Pressure from Pharisees was heavy and weak Jewish Christians really didn't like being split off from their families. The major power passed to Gentiles who had no such traditional bonds to overcome. However... PASSOVER customs from back then CLEARLY treat all elements as metaphorical. And, the symbolic communion WORKS... spiritual renewal rededicating them to the exaltation of Jesus Christ can be sensed by sincere participants. Unless Christ is so flexible that He will transsubstantiate into skeptical Baptists' bread and grape juice, something else is happening here.
Very nicely done. Casting pearls before swine, but still very good.
