This entire passage has to be read in context to get the proper meaning.
This passage is about believing in Him....not eating/drinking.
The Jews missed the point much as RCs are missing the point.
IF you have to eat/drink the flesh and blood then Jesus left out something very important to Nicodemus as He did not tell him about this.
Nor did He tell this to the Samaritans.
What He did tell them about though was faith.
John records this numerous times in his Gospel.
I gave the verses VERBATIM upthread.
Quoting the next paragraph does NOT undo it.
The poster doesn’t want the True meaning / proper meaning. He wants to believe the Catholic explanation because his pride needs that working for eternal life Catholicism meme. Pride in self works is at the heart of the blindness ... and Jesus will give them the same treatment he gave the unbelievers, seekers after signs and magic. He will leave them to their blasphemies.
