In Luke’s account of Jesus instituting the Lord’s Supper, he chases the eating and drinking with two surprising things.
The first thing that Luke relates after the New Covenant meal is that “a dispute arose among them, as to which of them was to be regarded as the greatest” (Luke 22:24). This may not be the correct chronology, as both Matthew’s account and John’s account of the night of Jesus’ betrayal do not mention this argument between the disciples as happening between the Last Supper and Gethsemane. But it is interesting that Luke would back the two events together. Jesus just said that He was going to suffer, that His blood would be poured out after a betrayal. Then Luke wrote that His men were fighting like kids. It may be because they didn’t fully understand yet, which they didn’t, and it could also be some because men still think that those who serve are not the greatest. Jesus said, “But I am among you as one who serves.”
The second and very next thing that Luke records, after describing the Supper and the greatness of serving, is the coming Kingdom in which His disciples would have positions of greatness.
“You are those who have stayed with me in my trials, and I assign to you, as my Father assigned to me, a kingdom, that you may eat and drink at my table in my kingdom and sit on thrones judging the twelve tribes of Israel.” (Luke 22:28-30).
Now would have been a great time for Jesus to correct their false expectations about a national Messiah-King fulfilling Old Testament prophecies concerning the Lord’s rule on earth. Not only did Jesus not correct those expectations, He made them even more personal for His disciples.
The communion table is a foretaste of the Table of the King. We eat and drink around it, not in expectation of a great allegorical table in the sky, but in expectation that Jesus will return in body and reign just as He said. There will be physical bread and wine, and thrones, and we will see them because He gave body and blood for us.
