“Your ancestors ate the manna in the desert, but they died;
this is the bread that comes down from heaven so that one may eat it and not die.
I am the living bread that came down from heaven; whoever eats this bread will live forever; and the bread that I will give is my flesh for the life of the world.”
The Jews quarreled among themselves, saying, “How can this man give us (his) flesh to eat?”
Jesus said to them, “Amen, amen, I say to you, unless you eat the flesh of the Son of Man and drink his blood, you do not have life within you.
Whoever eats my flesh and drinks my blood has eternal life, and I will raise him on the last day.
For my flesh is true food, and my blood is true drink
Whoever eats my flesh and drinks my blood remains in me and I in him.
Just as the living Father sent me and I have life because of the Father, so also the one who feeds on me will have life because of me.
This is the bread that came down from heaven. Unlike your ancestors who ate and still died, whoever eats this bread will live forever.”
These things he said while teaching in the synagogue in Capernaum
Then many of his disciples who were listening said, “This saying is hard; who can accept it?”
Since Jesus knew that his disciples were murmuring about this, he said to them, “Does this shock you?
What if you were to see the Son of Man ascending to where he was before?
It is the spirit that gives life, while the flesh is of no avail. The words I have spoken to you are spirit and life.
But there are some of you who do not believe.” Jesus knew from the beginning the ones who would not believe and the one who would betray him.
And he said, “For this reason I have told you that no one can come to me unless it is granted him by my Father.”
As a result of this, many (of) his disciples returned to their former way of life and no longer accompanied him
Jesus then said to the Twelve, “Do you also want to leave?”
Simon Peter answered him, “Master, to whom shall we go? You have the words of eternal life.
We have come to believe and are convinced that you are the Holy One of God.”
Jesus answered them, “Did I not choose you twelve? Yet is not one of you a devil?”
He was referring to Judas, son of Simon the Iscariot; it was he who would betray him, one of the Twelve.” [John 6: 49-71]
So the questions must be asked which RCs ignore:
1. Consistent with your literal interpretation here, no one can have spiritual life in them and eternal if they do not believe in the Catholic real presence, correct ?
2. Where in Scripture (even though that is not your real basis for assurance) did the apostles preach taking part in the Lord's supper in order to gain spiritual life in them? Or where does it show believers being ? Or show souls not being born again, thus having spiritual life in them, until they took part in the Lord's supper?
3. Where in all the aspects which John writes of in 1 John so that souls may know they have eternal life (cf. 5:13) does he teach that receiving the Catholic real presence is that means?
4. Where are the verses in John 6 that you listed infallibly interpreted, or is this something you can disagree refers to the Catholic real presence (i say "Catholic," because evidently it was the Anglicans that first began using the phrase)
Anyone on your list can fill in for you. But if you respond, this time refrain from resorting to your perfunctory images as a substitute for an argument.
