14When the hour came, Jesus and his apostles reclined at the table. 15And he said to them, “I have eagerly desired to eat this Passover with you before I suffer. 16For I tell you, I will not eat it again until it finds fulfillment in the kingdom of God.”
There is that word again, πληρόω “complete, fullfill”, this time in the passive subjunctive—through Him, the Passover is to “be completed”. In the Passover, God intended to “paint us a picture” of a purpose so vitally important that He ordained a yearly commemoration of it that persists to this day. Now Jesus completes the picture for us, and ordains a commemoration of the Passover of the New Covenant:
19And he took bread, gave thanks and broke it, and gave it to them, saying, “This is my body given for you; do this in remembrance of me.” 20In the same way, after the supper he took the cup, saying, “This cup is the new covenant in my blood, which is poured out for you.
As the Passover commemorates God’s deliverance through Moses of the children of Israel from slavery in Egypt, so the “Lord’s Supper”, as we usually call it, commemorates God’s greatest deliverance through Jesus Christ of all of His children from slavery to sin and death.
Our Church’s celebration of the Holy Week again this year included a demonstration by Jewish members of our congregation of some of the elements of the traditional Seder observance, to remind us of this connection between the Old and the New.
