If Jesus could speak today he would be appalled at the words which have been put into his mouth by his followers

 

Words such as these:

And he took the cup, and gave thanks, and gave it to them, saying, Drink ye all of it; For this is my blood of the new testament, which is shed for many for the remission of sins.

-- Matthew 26:27f.

And he took the cup, and when he had given thanks, he gave it to them: and they all drank of it. And he said unto them, This is my blood of the new testament, which is shed for many.

-- Mark 14:23f.

Likewise also the cup after supper, saying, This cup is the new testament in my blood, which is shed for you.

-- Luke 22:20

Then Jesus said unto them, Verily, verily, I say unto you, Except ye eat the flesh of the Son of man, and drink his blood, ye have no life in you. Whoso eateth my flesh, and drinketh my blood, hath eternal life; and I will raise him up at the last day. 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.

-- John 6:53ff.

 

A Jewish Jesus would have thought such words as those to be an abomination. He preached instead a gospel of the fatherhood of God, of the imminent coming of God's kingdom with judgment, of radical renunciation of the world because it was about to be destroyed, of the necessity of mutual forgiveness of sins, of God's desire for mercy and not sacrifice, of the perpetuity of the law until heaven and earth pass away.

And here is the law on the subject, loud and clear:

 

But flesh with the life thereof, which is the blood thereof, shall ye not eat.

-- Genesis 9:4

It shall be a perpetual statute for your generations throughout all your dwellings, that ye eat neither fat nor blood.

-- Leviticus 3:17

Moreover ye shall eat no manner of blood, whether it be of fowl or of beast, in any of your dwellings. Whatsoever soul it be that eateth any manner of blood, even that soul shall be cut off from his people.

-- Leviticus 7:26f.

For the life of the flesh is in the blood: and I have given it to you upon the altar to make an atonement for your souls: for it is the blood that maketh an atonement for the soul. Therefore I said unto the children of Israel, No soul of you shall eat blood, neither shall any stranger that sojourneth among you eat blood. And whatsoever man there be of the children of Israel, or of the strangers that sojourn among you, which hunteth and catcheth any beast or fowl that may be eaten; he shall even pour out the blood thereof, and cover it with dust. For it is the life of all flesh; the blood of it is for the life thereof: therefore I said unto the children of Israel, Ye shall eat the blood of no manner of flesh: for the life of all flesh is the blood thereof: whosoever eateth it shall be cut off.

-- Leviticus 17:11ff. 

Ye shall not eat any thing with the blood: neither shall ye use enchantment, nor observe times.

-- Leviticus 19:26

Only ye shall not eat the blood; ye shall pour it upon the earth as water. ... Only be sure that thou eat not the blood: for the blood is the life; and thou mayest not eat the life with the flesh. Thou shalt not eat it; thou shalt pour it upon the earth as water. Thou shalt not eat it; that it may go well with thee, and with thy children after thee, when thou shalt do that which is right in the sight of the LORD.

-- Deuteronomy 12:16, 23ff.

Only thou shalt not eat the blood thereof; thou shalt pour it upon the ground as water.

-- Deuteronomy 15:23.

 

It beggars belief that a Jewish Jesus believed anything contrariwise.
