You want us to understand Jesus is being literal when He stood before His disciples with the bread and wine; you want us to believe these elements became His Body and His Blood. Ror that to happen, some of His Flesh and some of His Blood would have to leave His Body (still not crucified) and that doesn’t make sense (not that God has to make sense to me). It would be doing something prohibited by the Law - eating human flesh and drinking human blood.
Then there’s the verse where Jesus told His disciples to cut off their hands and poke out their eyes if they cause the disciple to sin. Sounds literal to me. Do you know anyone who has obeyed those commands by the Lord? I hope not. Of course Jesus was illustrating how bad sin is. BTW, I don’t think the eye or hand can cause us to sin; it’s our wicked heart (mind) that causes us to sin.
Christ did speak symbolically about food and each time explained what He meant.
**Joh 4:31 In the mean time, the disciples prayed him, saying: Rabbi, eat.
Joh 4:32 But he said to them: I have meat to eat which you know not.
Joh 4:33 The disciples therefore said one to another: Hath any man brought him to eat?
Joh 4:34 Jesus saith to them: My meat is to do the will of him that sent me, that I may perfect his work.
Mat 16:5 And when his disciples were come over the water, they had forgotten to take bread.
Mat 16:6 Who said to them: Take heed and beware of the leaven of the Pharisees and Sadducees.
Mat 16:7 But they thought within themselves, saying: Because we have taken no bread.
Mat 16:8 And Jesus knowing it, said: Why do you think within yourselves, O ye of little faith, for that you have no bread?
Mat 16:9 Do you not yet understand, neither do you remember the five loaves among five thousand men, and how many baskets you took up?
Mat 16:10 Nor the seven loaves, among four thousand men, and how many baskets you took up?
Mat 16:11 Why do you not understand that it was not concerning bread I said to you: Beware of the leaven of the Pharisees and Sadducees?
Mat 16:12 Then they understood that he said not that they should beware of the leaven of bread, but of the doctrine of the Pharisees and Sadducees.**
In John 6, Christ spoke about eating His flesh and drinking His blood. When His disciples found the teaching hard, He did not explain any symbolism.
Joh 6:60 (6:61) Many therefore of his disciples, hearing it, said: This saying is hard; and who can hear it?
Joh 6:61 (6:62) But Jesus, knowing in himself that his disciples murmured at this, said to them: Doth this scandalize you?
When many of His disciples left Him and walked with Him no more, Christ did not stop them and explain any symbolism, He turned to His Apostles and asked them a question.
Joh 6:66 (6:67) After this, many of his disciples went back and walked no more with him.
Joh 6:67 (6:68) Then Jesus said to the twelve: Will you also go away?
The Bible has several examples of eating flesh and drinking blood and each time it was symbolically representing ‘assaulting’. We know Christ was not telling His disciples and Apostles to ‘assault’ Him.
