On the Cross, Christ is both priest and victim; he fulfills Isaiah’s description of him as the suffering servant. And the whole of his teaching is to make us ready to live our sacramental life in his spirit of sacrifice. He impressed on us that we must match the outward sign of his sacraments in our lives. When we became other Christs in Baptism, we became other Christs in Baptisms, we became sharers in the priesthood of the Lord. We gained the ability and the responsibility of combining our inward obedience with every outward act of sacrifice that we make as priests and victims. In every Mass, then, we agree to offer our obedience to atone for, to correct the disobedience of sin. On his part, Christ agrees to renew his sacrifice of atonement and obedience, in which we join; and to nourish us on the victim, his flesh and blood, the covenant food.
