2,000 years of Christian teaching holds that Jesus was referring to the Eucharist which he instituted at the Last Supper.
You disprove it.
Don't eat the blood, the life is in the blood
Genesis 9:4 But you shall not eat flesh with its life , that is, its blood.
Leviticus 3:17 It shall be a statute forever throughout your generations, in all your dwelling places, that you eat neither fat nor blood.”
Leviticus 7:26-27 Moreover, you shall eat no blood whatever, whether of fowl or of animal, in any of your dwelling places. Whoever eats any blood, that person shall be cut off from his people.”
Leviticus 17:10-14 “If any one of the house of Israel or of the strangers who sojourn among them eats any blood, I will set my face against that person who eats blood and will cut him off from among his people. For the life of the flesh is in the blood, and I have given it for you on the altar to make atonement for your souls, for it is the blood that makes atonement by the life. Therefore I have said to the people of Israel, No person among you shall eat blood, neither shall any stranger who sojourns among you eat blood.
“Any one also of the people of Israel, or of the strangers who sojourn among them, who takes in hunting any beast or bird that may be eaten shall pour out its blood and cover it with earth. For the life of every creature is its blood: its blood is its life. Therefore I have said to the people of Israel, You shall not eat the blood of any creature, for the life of every creature is its blood. Whoever eats it shall be cut off.
Leviticus 19:26 “You shall not eat any flesh with the blood in it. You shall not interpret omens or tell fortunes.
Deuteronomy 12:16 Only you shall not eat the blood ; you shall pour it out on the earth like water.
Deuteronomy 12:23 Only be sure that you do not eat the blood, for the blood is the life , and you shall not eat the life with the flesh.
Deuteronomy 15:23 Only you shall not eat its blood; you shall pour it out on the ground like water.
Acts 15:12-29 And all the assembly fell silent, and they listened to Barnabas and Paul as they related what signs and wonders God had done through them among the Gentiles. After they finished speaking, James replied, “Brothers, listen to me. Simeon has related how God first visited the Gentiles, to take from them a people for his name. And with this the words of the prophets agree, just as it is written,
“‘After this I will return, and I will rebuild the tent of David that has fallen; I will rebuild its ruins, and I will restore it, that the remnant of mankind may seek the Lord, and all the Gentiles who are called by my name, says the Lord, who makes these things known from of old.’
Therefore my judgment is that we should not trouble those of the Gentiles who turn to God, but should write to them to abstain from the things polluted by idols, and from sexual immorality, and from what has been strangled, and from blood. For from ancient generations Moses has had in every city those who proclaim him, for he is read every Sabbath in the synagogues.”
Then it seemed good to the apostles and the elders, with the whole church, to choose men from among them and send them to Antioch with Paul and Barnabas. They sent Judas called Barsabbas, and Silas, leading men among the brothers, with the following letter:
“The brothers, both the apostles and the elders, to the brothers who are of the Gentiles in Antioch and Syria and Cilicia, greetings. Since we have heard that some persons have gone out from us and troubled you with words, unsettling your minds, although we gave them no instructions, it has seemed good to us, having come to one accord, to choose men and send them to you with our beloved Barnabas and Paul, men who have risked their lives for the name of our Lord Jesus Christ. We have therefore sent Judas and Silas, who themselves will tell you the same things by word of mouth. For it has seemed good to the Holy Spirit and to us to lay on you no greater burden than these requirements: that you abstain from what has been sacrificed to idols, and from blood, and from what has been strangled, and from sexual immorality. If you keep yourselves from these, you will do well. Farewell.”
Jesus called the cup *the fruit of the vine*.
Matthew 26:29 I tell you I will not drink again of this fruit of the vine until that day when I drink it new with you in my Father’s kingdom.”
Mark 14:25 Truly, I say to you, I will not drink again of the fruit of the vine until that day when I drink it new in the kingdom of God.”
Luke 22:18 For I tell you that from now on I will not drink of the fruit of the vine until the kingdom of God comes.”
In John 6, at the end, Jesus tells that it is not physical eating that gives life, but Catholics wholesale ignore that verse, although it is part of the same passage.
John 6:63 It is the Spirit who gives life; the flesh is no help at all. The words that I have spoken to you are spirit and life.
Jesus came to fulfill the Law, not break it or do away with it.
He could not have either drank the cup if it were blood or commanded or demanded that the apostles do without making Him a lawbreaker, which would have meant He wasn't the spotless lamb of God.
He would have sinned.
Peter himself also said that he had never eaten anything unclean. Eating blood would have made him unclean and if he thought someone were telling him to eat blood, being an observant Jew wishing to celebrate the Passover, he would have refused.
Acts 10:14But Peter said, “By no means, Lord; for I have never eaten anything that is common or unclean.”
Your Old Testament quotes have no bearing. It seems you just flail illogically. Let’s stop discussing like this.
No, you made the statement.
It’s YOUR responsibility to prove it is valid.
It’s not a matter that someone has to accept any statement that someone throws out there until it can be disproved. It’s up to the person making the claim to provide proof that they are correct.
As that famous FReeper Iscool stated once......
“Why do you think we should have to run all over the internet searching for something that you claim is the truth??? You got something? post it...”
Here you go, by the grace of God. But once again disdain for extensive refutation can be excused as disdain for verbosity. By a RC no less.
