And then tells them that he won’t be drinking like that until a later similar event with all of the same friends in attendance (”I will not drink from this fruit of the vine from now on until that day when I drink it new with you”)

What was it that Jesus called it?? Will Jesus be drinking His own blood in heaven?

[Notwithstanding]

Where is the mystery?

Soon after the events of the Johannine “bread of life” discourse in which he loses a bunch of followers who don’t like it when he tells his followers emphtically that they must gnaw on his very flesh and drink his very blood,

Jesus ate a meal with the apostles and during that meal

Jesus gave bread to the apostles, said “this is my body” and told them to eat it;

Jesus then gave wine to the apostles, said “this is my blood” and told them to drink it.

Of both

the bread (which he held up saying “this is my body”)
and
the wine (which he held up saying “this is my blood”),

Jesus said he would not eat them again until a similar point in the future.

From the Scriptural accounts of this event, it would be hard to claim that Jesus will not someday share a similar meal with his disciples that will include his Body and his Blood.
