25 In the same manner He also took the cup after supper, saying, “This cup is the new covenant in My blood. This do, as often as you drink it, in remembrance of Me.” 26 For as often as you eat this bread and drink this cup, you proclaim the Lord’s death till He comes. (1 Corinthians 11:25–26, NKJV)
After the Passover meal, Jesus continued inaugurating His supper by telling His apostles to drink “this cup” which “is the new covenant in My blood.” He explained that the “fruit of the vine” (“the cup”) signifies His blood “which is shed for many for the remission of sins” (Matt. 26:28). The bread, symbolizing His body, and the juice of the grape, symbolizing His blood, constitute the elements of the Lord’s supper. His supper was not an extension of the Passover meal (a feast of the old covenant). Neither did Jesus institute His supper as part of a larger “fellowship meal” or “table fellowship” as some has contrived. It is a memorial meal during which unleavened bread and the juice of the grape are eaten in memory of the Lord’s death that dedicated His new covenant (by which the remission of sins is offered to all, Heb. 9:16-22). Until Christ returns, Christians proclaim His death each time they eat His supper. This simple and solemn memorial meal calls us back to Golgotha and the sacrifice of Jesus for the sins of the world. We must reverently and always partake of it as the Lord intended – as a memorial and a proclamation of His death.
