If Jesus wanted them to take it litteraly don’t you think he would have just cut a peice of his arm off and said “Take and eat, this is my body”?.
Of course not! Go back and re-read the Bread of Life discourse in John chapter 6. Then read “The Quail and the Manna” section of Exodus 16 (vs. 4-36 to be exact).
“I am the bread of life. Your ancestors ate the manna in the desert, but they died; this is the bread that comes down from heaven so that one may eat and not die.” (John 6:48-50)
Christ is saying the He, himself is the true Manna from heaven. Like the Jews is Exodus at the flesh and bread, so will the followers of Christ.
Futhermore, look at the Messianic prophecy in Zechariah 9.
“See, your king shall come to youl a just savior is he, meek and riding on an ***.” (vs. 9) “The Lord of hosts shall be a shield over them … they shall drink blood like wine…” (vs. 15)
The Bible is crystal clear. And so is Christ. When He spoke in parables, He let the followers know. The Bread of Life discourse is not a parable or a mere symbol. Christ was the ultimate sacrificial Lamb, slaughtered for us all. We eat his flesh (as was the custom of sacrifices in the Old Testament) and we drink his blood “like the corners of the alter” (Zech. 9:15).
He couldn’t “cut a piece of His arm off” because, as that sacrificial lamb, He had not yet been slaughtered. In the O.T., you didn’t eat the sacrifice until the ritual was complete, so it is with the Eucharist. The sacrifice is now done and we are able to participate in the sacrificial meal!
Praise be to God!
