On Thursday night of Holy Week, Jesus celebrated the Seder (the Passover meal) with his disciples in a borrowed room. The next night, the priests and all the citizens of Jerusalem celebrated their Seder. I have not been able to fact-check this statement, but I have read that at that time thousands of Jews did what Jesus and his disciples did: they came to Jerusalem for the Passover and celebrated the Seder a night early, while the citizens of Jerusalem celebrated on the night of the full moon.
The Seder and the week of Passover commemorated an event that had taken place twelve to fourteen centuries earlier. The Israelites were slaves in Egypt, but God sent Moses to command the pharaoh to release them. When the pharaoh refused, God sent a series of plagues against Egypt, showing that his power was greater than that of the Egyptian gods. The tenth plague was the death of the oldest son in every family, except that God spared those families that trusted him. They were told to kill a lamb, to paint the blood around the doors of their houses, and to roast and eat the lamb. They were to eat quickly, prepared to travel, because freedom was just around the corner. They were to bake bread without waiting for it to rise. That night the Israelites began their journey toward freedom, a journey which would take them to Mount Sinai where the Lord would say to them, “I will be your God, and you will be my people.”
Among the instructions God gave the Israelites through Moses was a command to observe the week of Passover every spring. During the week of Passover they would eat bread made without yeast, remembering the bread made during their hurried escape from Egypt, and also representing a life lived without sin. They would eat bitter herbs to remember the bitterness of slavery. They would kill and eat a lamb (without, however, painting the lamb’s blood on their houses), remembering the lamb of the Passover in Egypt and the way God rescued them both from slavery and from death.
God wanted his people to remember how he had rescued them in the past. He also wanted them to know how he would rescue them in the future. He killed the oldest son in every family among the Egyptians but spared the oldest son in every family marked by the blood of the lamb. In the same way, God spares all sinners marked by the blood of the Lamb of God who takes away the sin of the world (as John the Baptist described Jesus). Jesus is also the only-begotten Son of God, but he is the first-born son in a family that is filled with adopted children. The sacrifice of Jesus is the price paid to adopt all those children into the family of his Father. Like the bread made without yeast, Jesus lived a life without sin, yet he was broken on the cross so he could make whole the lives that have been broken by sin.
Jesus and his disciples came to Jerusalem to celebrate the Passover. They had their Seder meal on Thursday night. Later that night Jesus was arrested, tried, and convicted of blasphemy. Friday morning he would be handed over to the Romans, who would mock him, torture him, and crucify him. As the Passover lambs were being slaughtered for the Seder meals of the citizens of Jerusalem, the Lamb of God was shedding his blood and giving his life for all the sinners of history.
Through Moses, God commanded his people to celebrate the Passover every year. Some people continue to do so this year. On the other hand, Jesus fulfilled the meaning of the Passover celebration by his sacrifice and by his victory. The Israelites were led out of Egypt across the Red Sea toward the promised land the third day from the Passover. So also Jesus, on the third day, blazed a trail across the valley of the shadow of death to bring his people to a promised land—eternal life in a new and perfect creation that will have no end. J.
