22:14-18 The passover commemorated Israel's escape from Egypt when the blood of a lamb painted on their door frames saved their firstborn sons from death. This event foreshadowed Jesus' work on the cross. As the spotless Lamb of God, his blood would be spilled in order to save his people from the penalty of death brought by sin.
22:17, 20 Luke mentions two cups of wine, while Matthew and Mark mention only one. In the traditional Passover meal, the wine is served four times. Christ spoke the words about his body and his blood when he offered the fourth and last cup.
22:17-20 Christians differ in their interpretation of the meaning of the commemoration of the Lord's Supper. There are three main views: (1) the bread and wine actually become Christ's body and blood; (2) the bread and wine remain unchanged, yet Christ is spiritually present by faith in and through them; (3) the bread and wine, which remain unchanged, are lasting memorials of Christ's sacrifice. No matter which view they favor, all Christians agree that the Lord's Supper commemorates Christ's death on the cross for our sins and points to the coming of his kingdom in glory. When we partake of it, we show our deep gratitude for Christ's work on our behalf, and our faith is strengthened.
22:19 Jesus asked the disciples to eat the broken bread "in remembrance of me." He wanted them to remember his sacrifice, the basis for forgiveness of sins, and also his friendship that they could continue to enjoy through the work of the Holy Spirit. Although the exact meaning of Communion has been strongly debated throughout church history, Christians still take bread and wine in remembrance of their Lord and Savior, Jesus Christ. Do not neglect participating in the Lord's Supper. Let it remind you of what Christ did for you.
22:20 In the Old Testament times, God agreed to forgive people's sins if they brought animals for the priests to sacrifice. When this sacrificial system was inaugurated, the agreement between God and man was sealed with the blood of animals (Exodus 24:8). But animal blood did not in itself remove sin (only God can forgive sin), and animal sacrifices had to be repeated day by day and year after year. Jesus instituted a "new covenant" or agreement between humans and God. Under this new covenant, Jesus would die in the place of sinners. Unlike the blood of animals, his blood (because he is God) would truly remove the sins of all who put their faith in him. and Jesus' sacrifice would never have to be repeated; it would be good for all eternity (Hebrews 9:23-28). The prophets looked forward to this new covenant that would fulfill the old sacrificial agreement (Jeremiah 31:31-34), and John the Baptist called Jesus "the Lamb of god, who takes away the sin of the world" (John 1:29).
