Memorial is this Tuesday. While explaining the significance of consuming the booze and bread it is quite likely the speaker is going to make a passing remark about how Jesus made sure that Judas would not be present to partake.
Of course he won't explain his reason for saying that. But here is some food for thought while you're stuck sitting there listening to it:
All of the gospels contradict each other on the chronological order of events.
Of the four gospels, only Luke claims to be in logical order. (Although the witnesses claim that the word 'logical order' does not neccesarily mean 'chronological'.)
(Luke 1:3) I resolved also, because I have traced all things from the start with accuracy, to write them in logical order to you, most excellent The·oph′i·lus,Also, out of the four gospel accounts only the book of John mentions Judas leaving during the evening at all.
Matthews account includes all 12 apostles plus Jesus sitting down to eat.
Then Jesus telling the group that one of them at that table would betray him.
Followed by them passing the emblems.
Followed by them leaving and going to the garden.
Followed by Jesus telling Peter he would betray him 3 times.
No mention is made of Judas leaving before or after the wine. But nothing to indicate he was still around during the passing.
Marks account includes all 12 apostles plus Jesus sitting down to eat.
Then Jesus telling the group that one of them at that table would betray him.
Followed by them passing the emblems.
Followed by them leaving and going to the garden.
Followed by Jesus telling Peter he would betray him 3 times.
Pretty much the same as Matthew. No mention of Judas leaving. But nothing to indicate he was still around during the passing.
Lukes account includes all 12 apostles plus Jesus sitting down to eat.
First thing that happens is they pass the emblems.
Followed by Jesus telling telling the group that one of them at that table would betray him.
Followed by Jesus making a covenant with them.
Followed by Jesus telling Peter he would betray him 3 times.
Followed by them leaving and going into the garden.
Quite different from Matthew and Mark, this time Judas' presense is specifically mentioned AFTER the passing of the emblems. Again, no mention is made of him leaving at all.
Johns account includes all 12 apostles gathered in the upper room.
Jesus washes their feet and gives them a lesson.
Followed by Jesus telling the group that one of them would betray him.
Followed by Judas 'immediately' leaving. ("Therefore, after he received the morsel, he went out immediately. And it was night.")
Followed by Jesus telling Peter he would betray him 3 times.
Followed by Jesus giving a speech.
Followed by them leaving and going into the garden.
So John is very different from the rest. He's the only one to mention Judas leaving. Also he doesn't mention the passing of the emblems at all.
So what evidence do the witnesses claim to prove Judas left BEFORE the passing of them emblems? When the only gospel to mention Judas leaving at all, doesn't say when it happened in relation to the passing of the emblems?
Simple cherry picking. Clearly some of the gospels have to be out of order. So they choose to believe that Luke is completely jumbled and John is only partially out of order, but not out of order when it talks about Judas leaving right after Jesus says he will betray him.
One quick final point about the use of the word 'immediately' in John. When it says that Judas went out immediately after receiving the morsel.
The witnesses have no problem believing that the bible actually means what it says here. And you'd think that when the Bible says something happened immediately it means. . . well 'immediately'.
But when it's inconvenient for them, they are willing to redefine 'immediately' to mean 'a couple days later'.
They don't choose to do that in this case.
