Yes; indeed, and Jesus meant it just as much when he said “do this in
remembrance of Me…” (see Luke 22:19, 1 Cor. 11:24, 1 Cor. 11:25). Are you saying Jesus didn’t mean “remembrance” when He said it? **This is really pretty slick, P101. I am surprised you were not able to stay within one text but went shopping around.

John 6 stands alone in the sense that Christ is preparing us for the Last Supper. Christ’s words in John 6 repeat, and repeat, and repeat that He is talking about Himself being Food. No where else does He repeat like this. Maybe you should wonder why. **
In the Book of John alone, Jesus is described in figurative terms, such as “light,” (John 9:5) “truth,” (John 8:32, 14:6)," “good shepherd,” (John 10:11), “the door,” (John 10:9) “the resurrection and the life,” (John 11:25) “living water,” (John 4:10)
There is no Sacrament in the Catholic Church for LIGHT or for TRUTH or a GOOD SHEPHERD Sacrament or a LIVING WATER Sacrament. Surely if there was going to be a simple multiplicity sacraments based on misunderstood analogies there would be more then one. But, now we come to John 6 and Christ changes the way He makes His presentation - and, the fact that He continues to repeat Himself and correct the Jews as they (like you) originally thought Christ was merely using figurative languate. Christ stops them in their tracks. This is no metaphor - “My Flesh is REAL FOOD” Surely, when these statements are being made someone must have said, “My God, He’s serious!” This is the point where they (and, apparently you) walk away. Why? Well go back to your obvious source: the People’s NT Commentary - they give you the answer in black and white - it just does not make sense. So, either you have the Faith to submit your reason to Christ’s Authority, or you don’t. And, there hangs the tale.
“true bread,” (John 6:32) and a lot more. **This quote from John 6 repeats in different forms throughout. How many times do you think Christ repeated “light” to His listeners? Any idea why? Because they understood what He was saying. Any idea why he repeated "Food " in John 6 - because they didn’t until the end. And, in the end, they rejected Him and His Doctrine because it was "UNREASONABLE’. Don’t you see what is going on - our Faith in Christ is not based on REASON - it is based on Christ. **
Not one of these descriptions are intended as literal ones as in the Catholic doctrine of their Eucharist where they teach how they literally eat the literal flesh of Jesus.
This is where you get sloppy in your logic. There is a real difference between Christ’s use of figurative language and when He is being literal. If you lump them all togethr, then you will miss the point - Guranteed! If you take the time to analyze John 6 and how if literally differs from all of the other references you metion, you will see a change.
