From palm branches to passion, from hosannas to heckling, from majesty to mockery. This is the Sunday of the Passion, and the blood of Jesus Christ is the scarlet thread running throughout the entire passion history. As God said to the Israelites (Leviticus 17:11), "…the life of the flesh is in the blood; and I have given it for you upon the altar to make atonement for your souls; for it is the blood that makes atonement, by reason of the life." So then, throughout this holiest of all weeks, we are carried upon the river of the Most Precious Blood of our Lord and Saviour, Jesus Christ.
What had been the cup of the Passover is now the Cup of our salvation, transformed by Jesus when He said, "Drink from it, all of you; for this is the Cup of my blood in the New Covenant, which is poured out for many for the forgiveness of sins." The God who turned the water of the Nile into a river of blood in Egypt, the God who made water into wine at Cana, now makes Passover wine His own blood. It is the Lord's Passover, and such a Passover there had never been before.
At the first Passover, it was the blood of the sacrificial lamb, smeared upon the doorposts of the houses, which protected the lives of the first-born from death. The Angel of Death “passed over” where the blood was. But now, at this Passover, the Lamb is not only the sacrifice, but He is the Lord to whom the sacrifice is offered. His blood, the Blood of the Lamb, isn’t smeared on doorposts, but it’s drunk from His Chalice, and it covers our sins and shields us from death. His blood is the blood of the covenant, both ancient and new. The covenant is God's claim on His people. "I will be your God, and you will be my people." At Mt. Sinai, Moses sprinkled the covenant blood upon the people and said, “Behold the blood of the covenant which the LORD has made with you in accordance with all these words.” In the upper room, Jesus gave His blood of the new covenant to His Twelve, His new Israel. “Drink of it, all of you, for this is my blood of the covenant, which is poured out for many for the forgiveness of sins.” Jesus binds Himself to His people in every generation by His blood.
On the cross, Christ’s blood was shed, once for all people. It is Covenant blood; innocent blood; cleansing blood; poured out for you and for all mankind. It was the blood of God’s Passover Lamb which stained the wood of the cross, and it’s the cross which is the doorpost of the Church – and death passes over the house where the Passover Lamb’s blood has been smeared. And so, the blood is for us.
In the Mass, we come to Jesus, the mediator of the new covenant, and we come through the blood that speaks more graciously than the blood of Abel. Here Christ delivers, offers and applies His blood to us. And we must receive the blood of the Lamb in all the ways He promises to give it to us - in Baptism, in Absolution, in the Mass. For completely different reasons than they were for that crowd in Jerusalem screaming for his death, we say, “Let His innocent and cleansing blood of the covenant be upon us and upon our children,” because there is life in His blood, and there is forgiveness.
Almighty and everlasting God, who, of thy tender love towards mankind, hast sent thy Son our Saviour Jesus Christ, to take upon him our flesh, and to suffer death upon the Cross, that all mankind should follow the example of his great humility: mercifully grant that we may follow the example of his patience, and so be made partakers of his Resurrection; through the same Jesus Christ thy Son our Lord, who liveth and reigneth with thee, in the unity of the Holy Spirit, ever one God, world without end. Amen.
