Hi Vic,
You ask, "Is John Chapter 6 the Preparatory discussion of the promise from Jesus of the Eucharist?"
And, the answer is a resounding NO!
Then, you quote Matthew 26:26-27 -- but, you stop short. Why did you not include verses 28 and 29, where Jesus tells His apostles, "I will not drink of this fruit of the vine from now on until that day when I drink it new with you in My Father's kingdom."
Was Jesus drinking His own blood -- or was He speaking symbolically? The answer to that is simple; He was speaking symbolically. And, that is why you conveniently overlooked those two following verses.
Matthew 26:26-29 "While they were eating, Jesus took some bread, and after a blessing, He broke it and gave it to the disciples, and said, 'Take, eat; this is My body.' (27) And when He had taken a cup and given thanks, He gave it to them, saying, 'Drink from it, all of you; (28) for this is My blood of the covenant, which is poured out for many for forgiveness of sins. (29) But I say to you, I will not drink of this fruit of the vine from now on until that day when I drink it new with you in My Father's kingdom.' "
You did the same thing with Mark 14:
Mark 14:22-25, "While they were eating, He took some bread, and after a blessing He broke it, and gave it to them, and said, 'Take it; this is My body.' (23) And when He had taken a cup and given thanks, He gave it to them, and they all drank from it. (24) And He said to them, 'This is My blood of the covenant, which is poured out for many. (25) Truly I say to you, I will never again drink of the fruit of the vine until that day when I drink it new in the kingdom of God.' "
Drink His own blood?
And, you totally ignored Luke 22 and Luke is considered the best historian among all His disciples:
Luke 22:14-16, "When the hour had come, He reclined at the table, and the apostles with Him. (15) And He said to them, 'I have earnestly desired to eat this Passover with you before I suffer; (16) for I say to you, I shall never again eat it until it is fulfilled in the kingdom of God.'
Eat His own body, His own flesh? Really?
Luke 22:17-19, "And when He had taken a cup and given thanks, He said, 'Take this and share it among yourselves; (18) for I say to you, I will not drink of the fruit of the vine from now on until the kingdom of God comes.' "
Drink His own blood? Really?
Luke 22:19, "And when He had taken some bread and given thanks, He broke it and gave it to them, saying, 'This is My body which is given for you; do this in remembrance of Me.' "
Oh, now I see! We are to eat the bread and drink the wine in remembrance of Him. That makes sense.
But, I will give you credit. You did include 1 Corinthians 11:23-26 even though Paul reminds us twice that Jesus told us to take Communion, to take the elements, in remembrance of Him until He comes again.
1 Corinthians 11:23-26, "For I received from the Lord that which I also delivered to you, that the Lord Jesus in the night in which He was betrayed took bread; (24) and when He had given thanks, He broke it and said, 'This is My body, which is for you; do this in remembrance of Me.' (25) In the same way He took the cup also after supper, saying, 'This cup is the new covenant in My blood; do this, as often as you drink it, in remembrance of Me.' (26) For as often as you eat this bread and drink the cup, you proclaim the Lord's death until He comes."
You conclude by asking, "Is Jesus lying about the creation of the Sacrament of the Eucharist?"
No, but, then -- in those Scripture passages, Jesus is not speaking of the same thing the Roman Catholic church pushes. Jesus is speaking of eating the unleavened bread and drinking the wine or juice in remembrance of Him. And, the Roman Catholic church wants us to believe they are eating the actual flesh and drinking the actual blood of Jesus Christ.
Let's take a practical look at that. From 33 AD until now, how many folks do you think have eaten the Lord's Supper? Maybe about 10 billion, give or take a few? Now assume that each of us had one bite of His flesh and drank one small cup of His blood; then multiply that by about 10 billion. Wow! The human body of Jesus Christ would have to be tall enough to reach from earth to the moon. Not sure, but, I would guess that Jesus in His human body was about 5'8" or so.
But, for each of us to weekly take a bite of His flesh and drink a cup of His blood -- He would need to be about 238,900 miles tall, the distance from earth to the moon.
My Friend, can you see how ridiculous that is -- and how gullible one has to be to believe it?
God bless, have a wonderful, blessed day,
Bill
