In the Biblical account in the Book of Exodus, the blood of the sacrificial lamb was put on the doorposts of the People of God, and death ‘pass over’ their household – but not of that of the Egyptians who enslaved them. It was the event that liberated the People of God from their bondage to the Egyptians.
Ever since that event, the People of God celebrated the Passover feast as a memorial. This was the Last Supper feast that Jesus celebrated as He instituted the Mass. The true bondage in life is sin, and with sin, comes death. We could say, that the Exodus account was a preparation, and an anticipation of the true liberation from the bondage/enslavement to sin. To be delivered from that, we need the true sacrificial lamb – the Lamb of God that can take away the sins of the world! And that is exactly what John the Baptist said when he pointed his followers to Jesus: “Behold, the Lamb of God who takes away the sins of the world!”. They are also the exact words the priest says as he holds up the consecrated hosts that is the body of Christ, broken for us – Jesus is the sacrificial Lamb that takes away the sins of the world. The celebration of the Mass makes present again (re-“present”) the one and the same sacrifice of Christ at Calvary – to take away our sins, to give us life…..
May we respond with true humility: “Lord I am not worthy…..” and come before Him asking for mercy.
