In our sacraments of baptism and the Lord’s Supper we have direct connections to the corresponding sacraments of the old covenant, circumcision and Passover.
Jesus’s life began with the shedding of blood in circumcision, and it is in His circumcision that we are joined in baptism, Colossians 2:9-13. Just as circumcision was the removal of sinful flesh, so to is baptism the cleansing of sin, being brought out of Adam and into the church.
The Passover, which is also a bloody sacrament is given to us by Jesus at His Table. Paul says that we declare Christ’s death at our Passover in the New Covenant, 1 Corinthians 11:23-26, and His death means victory. When He died sin died with Him. When He died death died as well. The death of Jesus is a declaration of the victory of God and His people.
The Passover in the Old Covenant saw the firstborn of all Egypt slain and the people of God delivered from bondage. The New Covenant Passover sees the people of God delivered by the death of God’s firstborn in whom we have victory.
Circumcision and the Passover have come to us in the blood of Jesus, and now the sacraments are therefore bloodless. God requires no more blood from His people. Instead we receive upon us the refreshing waters of heaven, and the peaceful wine of the Kingdom.
Because Jesus’s life is book-ended with His blood, you need not shed your own. Jesus has fulfilled all righteous on your behalf, so come and welcome to Jesus Christ.
