The Eucharist is the Body, Blood, Soul and Divinity of Jesus.
Sorry, but in John 6, Jesus said this bread had already descended and then he tells us it is his flesh.
So start over.
33 For
the bread of God is that which (1) descends out of heaven and (2)
gives life to the world... 51 if anyone eats of
this bread, he will live forever and
the bread also which I will give
for the life of the world is my flesh. 52 Then the Jews began to argue with one another, saying, “How can this man give us
His flesh to eat?” 53 So Jesus said to them, “Truly, truly, I say to you, unless you eat
the flesh of the Son of Man and drink his blood, you have no life in yourselves. 54 He who eats
My flesh and drinks My blood has eternal life, and I will raise him up on the last day. 55 For
My flesh is true food, and my blood is true drink. 56 He who eats
My flesh and drinks my blood abides in me, and I in him. 57 As the living Father sent Me, and I live because of the Father, so he who eats me, he also will live because of me. 58
THIS is the bread which descends out of heaven; not as the fathers ate and died; he who eats
this bread will live forever.
Tell us how this flesh had descended out of heaven.
