-- if you read in the Bible, starting from John 6:30, we read
They asked Him for a sign, saying that Moses gave them manna in the desert. If Jesus (according to them) was aspiring to the level of Moses, He should do something as big as that.
30 So they asked him, What sign then will you give that we may see it and believe you? What will you do?
31 Our ancestors ate the manna in the wilderness; as it is written: He gave them bread from heaven to eat.
32 Jesus said to them, Very truly I tell you, it is not Moses who has given you the bread from heaven, but it is my Father who gives you the true bread from heaven.
33 For the bread of God is the bread that comes down from heaven and gives life to the world.
34 Sir, they said, always give us this bread.
35 Then Jesus declared, I am the bread of life. Whoever comes to me will never go hungry, and whoever believes in me will never be thirsty.
36 But as I told you, you have seen me and still you do not believe.
And now the crowd is openly rebellious saying How can this man give us his flesh to eat?
48 I am the bread of life. 49 Your ancestors ate the manna in the wilderness, yet they died.
50 But here is the bread that comes down from heaven, which anyone may eat and not die.
51 I am the living bread that came down from heaven. Whoever eats this bread will live forever. This bread is my flesh, which I will give for the life of the world.
Note -- Jesus doesn't clear up the Metaphor, like he did in Matt. 16:512
53 Jesus said to them, Very truly I tell you, unless you eat the flesh of the Son of Man and drink his blood, you have no life in you.
54 Whoever eats my flesh and drinks my blood has eternal life, and I will raise them up at the last day.
55 For my flesh is real food and my blood is real drink.
56 Whoever eats my flesh and drinks my blood remains in me, and I in them.
57 Just as the living Father sent me and I live because of the Father, so the one who feeds on me will live because of me.
58 This is the bread that came down from heaven. Your ancestors ate manna and died, but whoever feeds on this bread will live forever.
5 When they went across the lake, the disciples forgot to take bread.So, Jesus DOES indicate when it is a metaphor and when it isn't.
6 Be careful, Jesus said to them. Be on your guard against the yeast of the Pharisees and Sadducees.
7 They discussed this among themselves and said, It is because we didnt bring any bread.
8 Aware of their discussion, Jesus asked, You of little faith, why are you talking among yourselves about having no bread?
9 Do you still not understand? Dont you remember the five loaves for the five thousand, and how many basketfuls you gathered?
10 Or the seven loaves for the four thousand, and how many basketfuls you gathered?
11 How is it you dont understand that I was not talking to you about bread? But be on your guard against the yeast of the Pharisees and Sadducees.
12 Then they understood that he was not telling them to guard against the yeast used in bread, but against the teaching of the Pharisees and Sadducees.
You cannot say that this was just bread and wine of that this is a metphor for coming and having faith in the Lord or some kind of metphor for believing in Christ because of the reaction of the Jews and the very language -- to eat one's flesh and drink the blood means to do violence on some one. You see it even in Hindi where a threat is "Mein tera Khoon pie jaongaa" or "I will drink your blood" -- and this is among vegetarians! To drink a persons blood means a serious threat of injury.So, if you believe that this was just a metphor, you mean to say that Christ is rewarding people for crucifying Him?!! That's nonsensical, sorry.
60 On hearing it, many of his disciples said, This is a hard teaching. Who can accept it?...
66 From this time many of his disciples turned back and no longer followed him.
Even in the literal sense -- Christ says he is the gateway to heaven and the vine such that we get nourishment with him as the connecting path. But John 6 is much much more than mere symbolism as He categorically states that "For my flesh is food indeed, and my blood is drink indeed" (John 6:55).
Even at the end of John 6, Jesus rebukes those who think of what He has said as a metaphor by emphasising that
Jesus repeats the rebuke against just thinking in terms of human logic (Calvin's main problem) by saying
61 Aware that his disciples were grumbling about this, Jesus said to them, Does this offend you?
62 Then what if you see the Son of Man ascend to where he was before!
63 The Spirit gives life; the flesh counts for nothing. The words I have spoken to youthey are full of the Spirit[e] and life.
64 Yet there are some of you who do not believe.
Just using human logic as Calvinist thought does, without God's blessings behind it fails in grace.John 6:63 does not refer to Jesus's statement of his own flesh, if you read in context but refers to using human logic instead of dwelling on God's words.
John 8:15 You judge by human standards; I pass judgment on no one.
16 But if I do judge, my decisions are true, because I am not alone. I stand with the Father, who sent me.
and also 1 Cor 11:27-29
6 Is not the cup of thanksgiving for which we give thanks a participation in the blood of Christ? And is not the bread that we break a participation in the body of Christ?
How clear can Paul get? "The bread IS a participation in the body of Christ" and "who eats the bread... will have to answer for the body and blood of the Lord" This is not just mere bread and wine anymore. This is the body and blood of Christ.
27 So then, whoever eats the bread or drinks the cup of the Lord in an unworthy manner will be guilty of sinning against the body and blood of the Lord.
28 Everyone ought to examine themselves before they eat of the bread and drink from the cup.
29 For those who eat and drink without discerning the body of Christ eat and drink judgment on themselves.
as our Protestant Lutheran brethren say From the Lutheran LCMS.org website
All three accounts of the institution of the Lord's Supper in the Gospels (Matthew 26:26-29; Mark 14:22-25; Luke 22:14-23) explicitly state that Jesus took BREAD, blessed it, broke it, and gave it to his disciples saying, "Take, eat; this [i.e., this BREAD, which I have just blessed and broken and am now giving to you] is my body." Jesus uses similar language in referring to "the cup" (of wine) as "his blood."... Perhaps the most explicit expression of this truth, however, is found in 1 Cor. 10:16-17, where Paul writes: "The cup of blessing that we bless, is it not a participation in the blood of Christ? The bread that we break, is it not a participation in the body of Christ? Because there is one bread, we who are many are one body, for we all partake of the one bread." Paul clearly says here that we all "partake" of "BREAD" when we receive the Lord's Supper--even as we also partake of and "participate in" the true body of Christ. And he says that we all "partake" of the wine (the cup), even as we also partake of the true blood of Christ. Similarly, in 1 Cor. 11:26, Paul says: "For as often as you eat this bread and drink the cup, you proclaim the Lord's death until he comes." Paul expressly states here ........................that those who eat this bread and drink this cup are also partaking of the true body and blood of Christ. So "real" is this participation in Christ's body and blood, in fact, that (according to Paul) those who partake of the bread and wine "in an unworthy manner" are actually guilty of "profaning the body and blood of the Lord" (1 Cor. 11:27). (Partaking of the Lord's Supper "in a worthy manner," of course, is not something that we "do" or "accomplish" on the basis of our "personal holiness" or "good works." It means receiving God's free and gracious gifts of life and forgiveness offered in the Lord's Supper in true repentance produced by the work of the Spirit through God's Law and in true faith in Christ and his promises produced by God's Spirit through the Gospel).
Wrong, as you must ignoring what I just showed you, and thus jump from v. 60 to 66! Meanwhile, as explained, you not only do not take the words of consecration literally, but as you have been shown, only the metaphorical understanding easily conflates with Scripture, and the metaphysical Cath contrivance is not what the NT church manifestly believed.
Rather, in the context of 1 Co. 11:17-34 means to effectually remember and thus show/declare the sufferings and death of the Lord by manifesting its effect, that of unity with Christ and each other, redeeming souls and purchasing them with His sinless shed blood as the body of Christ.
Take heed therefore unto yourselves, and to all the flock, over the which the Holy Ghost hath made you overseers, to feed the church of God, which he hath purchased with his own blood. (Acts 20:28)
Which means that to remember the Lord's death is to show it, which here is by sharing food with fellow members of the body, confirming that they are such and as soul "bought with a price," and which thus are to be holy and caring for each other as members of that body of Christ, thus showing union with Him and each other.
For as often as ye eat this bread, and drink this cup, ye do shew the Lord’s death till he come. (1 Corinthians 11:26) For ye are bought with a price: therefore glorify God in your body, and in your spirit, which are God’s. (1 Corinthians 6:20)
Which holiness and caring union is so much emphasized by Paul in particular, as one who used to be persecute Christ by mistreating its members, and thus this theme continues into the next chapter.
And consistent with that emphasis Paul reproves the Corinthians for acting just the opposite of showing the Lord's death by how they treated its members for whom Christ died: Declaring that even though they came together for the purpose of eating the Lord's super, and were indeed eating under that presumption, yet they were not acting eating the Lord's supper, because they were acting completely contrary to what the Lord's death meant by mistreating members bought by His blood, thus not showing unity with Christ and each other, but treating members as if they were spiritually unclean:
Now in this that I declare unto you I praise you not, that ye come together not for the better, but for the worse. For first of all, when ye come together in the church, I hear that there be divisions among you; and I partly believe it. For there must be also heresies among you, that they which are approved may be made manifest among you. When ye come together therefore into one place, this is not to eat the Lord’s supper. For in eating every one taketh before other his own supper: and one is hungry, and another is drunken. What? have ye not houses to eat and to drink in? or despise ye the church of God, and shame them that have not? What shall I say to you? shall I praise you in this? I praise you not. (1 Corinthians 11:17-22)
Therefore the apostle re-minds of the Lord's institution of that memorial meal and its purpose,
For I have received of the Lord that which also I delivered unto you, That the Lord Jesus the same night in which he was betrayed took bread: And when he had given thanks, he brake it, and said, Take, eat: this is my body, which is broken for you: this do in remembrance of me. After the same manner also he took the cup, when he had supped, saying, This cup is the new testament in my blood: this do ye, as oft as ye drink it, in remembrance of me. (1 Corinthians 11:23-25)
Paul (by the Spirit of Christ) then adds,
For as often as ye eat this bread, and drink this cup, ye do shew the Lord’s death till he come. Wherefore whosoever shall eat this bread, and drink this cup of the Lord, unworthily, shall be guilty of the body and blood of the Lord. But let a man examine himself, and so let him eat of that bread, and drink of that cup. For he that eateth and drinketh unworthily, eateth and drinketh damnation to himself, not discerning the Lord’s body. (1 Corinthians 11:26-29)
It is not the nature of the bread and the cup that is the focus, but the purpose of the meal, which is to show (kataggellō: to proclaim, promulgate: - declare, preach, etc.) the Lord's death, which again is by sharing food with other members bought His the Lord's sinless shed blood. And thus to treat other holy members of that body as if they were outcasts was to not recognize the Lord's body, which Paul here refers to as the church he used to persecute.
Thus in the previous chapter the church is called "one bread, and one body: for we are all partakers of that one bread," (1 Corinthians 10:17) thereby showing communion/fellowship with Christ and each other, just like pagans have fellowship with demons by taking part in their dedicatory feasts, as would Christians if they took part in them:
Behold Israel after the flesh: are not they which eat of the sacrifices partakers of the altar? What say I then? that the idol is any thing, or that which is offered in sacrifice to idols is any thing? But I say, that the things which the Gentiles sacrifice, they sacrifice to devils, and not to God: and I would not that ye should have fellowship with devils. Ye cannot drink the cup of the Lord, and the cup of devils: ye cannot be partakers of the Lord’s table, and of the table of devils. (1 Corinthians 10:18-21)
Again, to take part in such feasts is to have fellowship with the object of the dedicatory feasts, but which was not be literally consuming the flesh and blood of them, while to act contrary to the Lord's death and its purpose, by mistreating holy members of it, is to not actually eat the Lord's supper and have and signify fellowship with Christ and each other.
And as that was the sin being reproved in 1 Co. 11:17-34, of some eating separately in lust for food, and ignoring others to their shame who were given nothing, then the solution was for members to examine their spiritual condition in the light of this, and as a practical measure, not come hungry to the Lord;'s supper, and be driven by hunger so as to treat it as if satisfying oneself with food itself was the purpose.
Wherefore, my brethren, when ye come together to eat, tarry one for another. And if any man hunger, let him eat at home; that ye come not together unto condemnation. And the rest will I set in order when I come. (1 Corinthians 11:33-34)
And as the body of Christ as the church (for whom Christ died) was the subject, then in the next chapter that theme continues.
Jesus MUST have been addled when He said this, "I am the bread of life. Whoever comes to me will never go hungry, and whoever believes in me will never be thirsty.", otherwise Catholics would spend VERY little for foodstuffs and drink.
