The worship of the Christian community culminates in the sacrifice of the Mass. At Mass, a priest, assimilated by his ordination to the High Priesthood of Christ, offers, in the name of Christ, a true sacrifice to God. This act of sacrifice is identified with our Lord’s sacrifice on Calvary for though the manner in which the victim is offered is different, the victim is the same. The body given and the blood shed is made present through the signs of the bread and the wine. More than that, Christ who died then and once and for all released the bonds of sin, is now, under the appearance of bread and wine, really present, so that his body and his blood become the heavenly food of the Christian community. This is the sacred passover meal at which the lamb is sacrificed that the people may be delivered. The lamb of God who offered himself, who gave himself upon the Cross as a pure and holy victim, offers himself again, by the ministry of priests, in an act of adoration, love and generosity.

The Mass is the memorial of that sacrifice that makes all other sacrifice acceptable, of the sacrifice through which the world is overcome. It is the union of the people of God with their risen Lord; hence it is the sign of victory. The life of the Church which is constituted by the victory of Christ, is one in which we share in the gifts won for us by Christ.
