This is a false opposition. I have faith in Jesus who said, “This is My Body.”
Jesus also said He was bread, the shepherd, the vine and the door.
And only one is not a metaphor?
I don’t think so.
God is clear in Scripture that blood is NOT to be eaten. Jesus could not have had His disciples eat it or commanded them to eat it (sin) or He would not have been sinless. He would have sinned in making others sin, thereby rendering Himself incapable of being the spotless lamb of God.
Reading it as a metaphor and recognizing the act as symbolic is the only way to read it without twisting or distorting or disobeying the rest of Scripture.
The theological gymnastics needed to justify Jesus commanding others to sin is staggering.
Jesus is the bread of life.
