John's statement does NOT preclude the validity of what Jesus said to the twelve inclusive of Judas
Judas wasn't there with the others when Jesus spoke Luke 22:28-30.
Jesus' statements are valid.
John's statements are valid.
Luke's account is valid.
Poof, simple logic tells us that Judas wasn't there when you claim he was there to hear Jesus speak Luke 22:28-30.
John 13:26-30 (NKJV) Jesus answered, “It is he to whom I shall give a piece of bread when I have dipped it.” And having dipped the bread, He gave it to Judas Iscariot, the son of Simon. Now after the piece of bread, Satan entered him. Then Jesus said to him, “What you do, do quickly.” But no one at the table knew for what reason He said this to him. For some thought, because Judas had the money box, that Jesus had said to him, “Buy those things we need for the feast,” or that he should give something to the poor. Having received the piece of bread, he then went out immediately. And it was night.
Judas left immediately after a piece of bread was dipped and served by Jesus to Judas, yes after supper, and after Satan entered Judas and after Jesus told him to leave quickly. That's the point.
Luke 22:20-21 (NKJV) Likewise He also took the cup after supper, saying, “This cup is the new covenant in My blood, which is shed for you. But behold, the hand of My betrayer is with Me on the table.
They had already eaten supper and Judas was still there at this point (obviously). Then, taking a piece of bread Jesus dips it in wine and served it to Judas. Then Satan entered Judas. Then Jesus told Judas to leave quickly and do what he must. And Judas did just that very thing. He left quickly/immediately. Simple. True. Valid.
But that claim won't work for several reasons.
The event of departure transpired after supper.
I know. That's what both (Luke 22:20) and John (John 13:2) say. Jesus dipped a piece of bread in wine and gave it to Judas after supper. So???
Even after they ALL had their feet washed,
Yes, they had their feet washed prior to supper, then ate supper. So??? Then Jesus dipped a piece of bread into the wine and served it to Judas. Then Satan entered Judas. Then Jesus told Judas to leave quickly and he did just that very thing.
Even after they ALL had their feet washed, which we can correlate right to
Luke 22:27 ( and to
John 13:16)
Jesus washes their feet and says:
John 13:16 (NKJV) Most assuredly, I say to you, a servant is not greater than his master; nor is he who is sent greater than he who sent him.
Jesus
sent Judas away with Satan in him immediately/quickly. Jesus is greater than them both.
Luke 22:27 (NKJV) For who is greater, he who sits at the table, or he who serves? Is it not he who sits at the table? Yet I am among you as the One who serves.
Judas was no longer sitting at the table nor among them. As I said. Jesus just got through sending them away, per John 13:16 and John 13:2 AND Luke 22:27...
There is no conflict with these separate accounts. There is conflict if Judas didn't actually leave immediately/quickly after Jesus sent him to do what he must do, though.
