It is the Holy Spirit which comes upon the bread and wine just as He came upon Mary to conceive Jesus.
It was flesh which died for our sins on Calvary, flesh and blood which suffered so that we might live.
Not just any flesh though, as no man since Adam could redeem us.
Jesus used parables, but He often was more direct with His Apostles and when they did not understand the message behind the parable, they asked.
When Jesus speaks of His body and blood as TRUE food and drink, many left Him. He asks those who did not, what they thought of this “hard saying”, but He never indicates that what they have heard is a parable or symbolic.
Jesus spoke quite alarmingly about the Bread of Life and never once tempered what He said. But, on the night before He was betrayed, He showed them how He would fulfill His words and how they were to remember Him.
Good job of spitting out a verse, which does not mean what you think it means to deflect from my question.
I will ask again.
Why does Jesus say what He says about eating His flesh and drinking His blood?
