CCC 613 Christ’s death is both the Paschal sacrifice that accomplishes the definitive redemption of men, through “the Lamb of God, who takes away the sin of the world”,1 and the sacrifice of the New Covenant, which restores man to communion with God by reconciling him to God through the “blood of the covenant, which was poured out for many for the forgiveness of sins”.2
CCC 2060 The gift of the commandments and of the Law is part of the covenant God sealed with his own. In Exodus, the revelation of the “ten words” is granted between the proposal of the covenant3 and its conclusion – after the people had committed themselves to “do” all that the Lord had said, and to “obey” it.4 The Decalogue is never handed on without first recalling the covenant (“The LORD our God made a covenant with us in Horeb.”).5
