The ones who did not believe misunderstood Jesus to mean litterally eat his flesh as a piece of meat and drink his blood litterally as to drink blood from a human.
The other misconception that cannot be taken from this text is symbolic. Jesus never gives this inclination of a symbolic meaning to eating his flesh and drinking his blood, otherwise the other disciples would of never left him.
Peter gives us the clue here to this bread of life discourse; from verse 68 Simon Peter answered him, “Lord, to whom shall we go? You have the words of eternal life; and we have believed, and have come to know, that you are the Holy One of God.”
When scripture speaks of a “spirit” scripture relates to the whole being of the person. To be the Holy One of God (Jesus) means that the substance that Jesus maintains in his humanity is both fully human and fully divine.
Our carnal understanding of the body does not equate with what Jesus is teaching here. On this side of death our bodies maintain a boundary which seperates each of us from our true being and limits our communion with one another. Much more can be defined from the senses here and how the body can become a bridge that unites our humanity, but these definitions only limit our understanding to the mystery or substance from which Jesus is speaking in regards to “the spirit that gives life, and the flesh is of no avail”.
The gospel of John when interpreted in the full context reveals the resurrection. Jesus resurrection reveals that the body ceases to be limited and from its capacity for communion eternally remains.
Jesus is not a piece of meat from his resurrection, Jesus cannot be measured and quantified, Jesus is not part of a bread or does not cohabit himself with a piece of bread because Jesus is other and greater than bread. Jesus is never symbolic either, to think thus, denies the existance of Jesus resurrection.
No a transformation has occurred. Spirit never ever reveals a symbolism or to describe a person outside of oneself. Spirit describes the eternal being of the person of Christ, for God is Spirit that gives life, as Peter qualified his belief in Jesus from vs. 68 above.
The flesh is of no avail, in other words, our (carnal) understanding from the flesh falls to dust, whereby it is by the Spirit that gives life to what ever God wills to, because the flesh by itself cannot do nothing without God.
When the Holy One of God (Jesus) words speak to the bread and wine “This is my body, this is my blood” a transformation occurrs, not according to the flesh but according to the eternal “Spirit” which gives life.
The bread and wine become “transubstantiated” into the body, blood, soul and divinity of Jesus Christ, the “Spirit has given life to these”, never the flesh, and when we enter into communion with Jesus as He consumes us as we eat his body and drink his blood. It is the spirit that communes and consumes us to give us eternal life to our souls (spirit) not our flesh, because we will be given new eternal bodies in the resurrection.
In summary, when we recieve holy communion, we are recieving the True presence of Jesus body, blood soul and divinity in the True presence of the Spirit which gives life to the transubstantiated bread and wine at the Words from the Holy One of God (Jesus), this is the “medicine of immortality” (St. Ignatius of Antioch) to our soul (spirit), but to our flesh they availeth nothing, because to our flesh (senses) they remain bread and wine.
At Jugdement day when God takes an accounting of your life on earth, God will ask your soul, “where is the body and blood I gave you to eat in order to have eternal life”? What will your soul respond today to the Eucharist? Amen? or will you leave Jesus true presence, and deny his body, blood, soul and divinity in His Eucharistf from Jesus substance of the “Spirit that gives life”, but to our flesh they availeth nothing, but to our soul the Eucharist is the “medicine of immortality”.
Peace be with you
***Can we have a Chairitable Discussion on John 6: 63-64?
John.6 Verses 63 to 64***
[Jesus Speaking] “It is the spirit that gives life, the flesh is of no avail; the words that I have spoken to you are spirit and life. But there are some of you that do not believe.” For Jesus knew from the first who those were that did not believe, and who it was that would betray him."
