THE NEW TESTAMENT ACCOUNTS of the "words of institution": — i.e., the words that institute the Lord' s Supper as an ongoing rite — vary somewhat, but their commonalities are striking. Luke 22:7-20 allows us to reflect on some elements of one of those accounts.
All three synoptic Gospels indicate that Jesus ordered his disciples to prepare for a Passover meal; Luke stresses the point (22:1, 7-8, 11, 15). Jesus wants his own actions and words to be understood in the light of that earlier traditional feast. The Passover celebrated not only the release of the Israelites from bondage, but the way that release was accomplished: in God' s plan, the angel of death "passed over" the houses protected by the sacrificial blood, while all the other homes in Egypt lost their firstborn. Moreover, this miraculous exodus set the stage for the inauguration of the Sinai covenant. So when Jesus now takes bread at a Passover meal and says, "This is my body given for you" (22:19), and when he takes the cup and says, "This cup is the new covenant in my blood, which is poured out for you" (22:20), one hears more than overtones from the old covenant ritual. This side of the cross, one cannot avoid the conclusion that Jesus sees his own death, the shedding of his own blood, as the God-provided sacrifice which averts the wrath of God, that he himself is the Passover Lamb of God par excellence, and that his death establishes a covenant with the people of God by releasing them from a darker, deeper slavery.
Someone has said that the four most disputed words in the history of the church are "This is my body." Without entering the lists on all that might be said about this clause, surely we can agree that one of its functions, as it is repeated in the ritual that Christ Jesus himself prescribed, is commemorative: "Do this in remembrance of me" (22:19). It is shocking that this should be necessary, in exactly the same way that it is shocking that a commemorative rite like the Passover should have been necessary. But history shows how quickly the people of God drift toward peripheral matters, and end up ignoring or denying the center. By a simple rite, Jesus wants his followers to come back to his death, his shed blood, his broken body, again and again and again.
It is also an anticipatory rite. It looks forward to the consummated kingdom, when the Passover and the Lord' s Supper alike find their fulfillment (22:16, 18). We eat and drink as he prescribes "until he comes" (1 Cor. 11:26), when commemoration and proclamation will be swallowed up by the bliss of his presence.
