No, He didn't say the physical flesh or the physical blood. He said that His words were spirit and that the flesh profits nothing. I suppose you also believe Jeremiah actually ate the physical scroll also?
>>Can Jesus change that law with regard to “His Body and Blood”?<<
And then the apostles change it back again after His ascension?
Acts 15:29 That ye abstain from meats offered to idols, and from blood, and from things strangled, and from fornication: from which if ye keep yourselves, ye shall do well. Fare ye well.
Do you see any exceptions in that statement? It's preposterous to think that the apostles sent a letter to all the churches to tell them not to eat blood but then have them sit down and drink blood.
Your comment; “Do you see any exceptions in that statement? It’s preposterous to think that the apostles sent a letter to all the churches to tell them not to eat blood but then have them sit down and drink blood.”
Then why did the Apostles continue the Mass and the Eucharist and give the “Body and Blood of Jesus” to Catholics. And this has continued for 2000 years.
So you do not see any difference between the “Body and Blood” of Jesus and animal blood?
You say that Jesus is a sinner based on the Last Supper and that Jesus and the Apostles consumed His Body and Blood. And for His instructions to do this in memory of me.
