Catholics don't have a corner on the market.
They are the only ones, however, who claim to be doing it the *right* way, which is basically according to their teaching.
However, that teaching violates a whole bunch of other Scripture, therefore their interpretation of that verse is wrong and Jesus Himself even clarified when He said that the flesh profits nothing. It's the SPIRIT that gives life.
Don't eat 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 18 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.”
This is my body, which will be given up for you. It profits nothing.
What an odd interpretation. Do you really think Jesus was saying his body would achieve nothing?
Why was He Incarnated if the flesh gets Him (and us) nothing?
Exactly. Exactly! And that's what makes it so striking--- no, stunning, shocking --- when Jesus says, "Eat my body, drink my blood." Not just once, but at least half a dozen times. And when people start to object, He doubles down on it. (Ref: John 6, toward the end of all three Synoptics, and Corinthians).
The Jews knew very well that this is forbidden in Mosaic law, and that is why so many of them took offense and stopped following Him. Why? Because they didn't care for His metaphors? No, but because they couldn't tolerate the shocking realism of what He was saying. What a gripping way to proclaim that His Blood, and His alone, is to be drunk: for that is His very life, and ours.
For my flesh is meat indeed, and my blood is drink indeed. He that eateth my flesh, and drinketh my blood, dwelleth in me, and I in him... Many therefore of his disciples, when they had heard this, said, This is an hard saying; who can hear it?
When Jesus knew in himself that his disciples murmured at it, he said unto them, Doth this offend you? ... From that time many of his disciples went back, and walked no more with him. Then said Jesus unto the twelve, Will ye also go away? Then Simon Peter answered him, Lord, to whom shall we go? thou hast the words of eternal life."
