John 6:37-68 is about coming to and believing in Christ to have eternal life, He being the true manna from heaven. Has nothing to do with the Passover remembrance.
It has everything to do with the New Covenant feast Jesus established at the Passover.
The first condition for receiving Jesus flesh and blood, is believing Jesus flesh is real food and blood real drink. Believing Jesus words is “believing in Jesus “.
Those that walked away had no Faith in Jesus words. These were like those invited to the feast, but made their excuses not to. Mainly that they thought Jesus was crazy.
Judas didn’t have faith in Jesus words either, but what was different is he didn’t walk off like the others, he tried to attend this feast without the garment of Faith.
“ Did I not choose you twelve, yet one of you is a devil “
“ But some of you refuse to have faith in me." Jesus said this, because from the beginning he knew who would have faith in him. He also knew which one would betray him “
When did Judas betray Jesus, at which future moment.
“When Judas had eaten the bread, Satan entered into him. Then Jesus told him, “Hurry and do what you’re going to do.”
So instead of entering Covenant Communion with Christ when Judas ate Jesus Body, by not believing Jesus words in Faith, Satan entered Judas.
This is the singularity of Faith that all men must pass. There is no other way into this feast, but believe Jesus words above all else, that is “ believing in Christ “.
The walk always said “ How can this man give us his flesh to eat “
Mistake 1: Jesus isn’t just a “ man “ He is God as well.
Mistake 2: stems from the first, not truly believing in Jesus Divinity will make human minds consider all the practical, cultural and even religious and scientific reasons why Jesus words would be false and impossible. The flesh profits nothing, human reason can not take you to where Faith will carry you.
Those that walked away were the most honest in a way. They didn’t try to rationalise Jesus Words to mask their unbelief. It was a hard teaching, who could even listen to it.
Human flesh ain’t kosher, nor even but especially blood, nor would there be enough of Jesus flesh and blood to go around, nor can we see a scientific change in the bread and wine. All these human considerations prevent Faith in Jesus words. Protestants have said these things to me all the time.
Judas stayed with Jesus but in unbelief of His words, and entered the feast without the garment of Faith. But be like Peter at that moment of hard teaching, make a supernatural act of Faith in Jesus Words.
“ You have THE WORDS of Everlasting Life “ Who else can we go to or trust.
Jesus words stand for all time and Eternity, not for you to doubt, but believe and live.
“Heaven and earth will pass away, but my words will never pass away “
Do not say in your hearts ‘ Lord, why did you have say those words that way, because now we have stupid deluded Catholics running around saying that your flesh is real food and blood real drink, how are we now to convince them otherwise ‘.
This is not the way to approach these Words of Christ, you must confront every doubt in your inner most part and reject them all, and enter the singularity of Faith with total abandonment and trust in Jesus words. Receive the garment and take your place. Believe.
At Judgement, if the Lord asks you why you believed that His Flesh is real food and blood real drink to eat and drink unto life Eternal.
Tell Him, ‘ You said it, and I believed it. You have the words of Everlasting Life ‘.
