Everything begins, one might say, from the heart of Christ who, at the Last Supper, on the eve of his passion, thanked and praised God and by so doing, with the power of his love, transformed the meaning of death which he was on his way to encounter. The fact that the Sacrament of the Altar acquired the name “Eucharist” — “thanksgiving” — expresses precisely this: that changing the substance of the bread and wine into the Body and Blood of Christ is the fruit of the gift that Christ made of himself, the gift of a Love stronger than death, divine Love which raised him from the dead. This is why the Eucharist is the food of eternal life, the Bread of Life. From Christ’s heart, from his “Eucharistic prayer” on the eve of his passion flows that dynamism which transforms reality in its cosmic, human and historical dimensions. All things proceed from God, from the omnipotence of his Triune Love, incarnate in Jesus. Christ’s heart is steeped in this Love; therefore he can thank and praise God even in the face of betrayal and violence, and in this way changes things, people and the world.
--Benedict XVI (Corpus Christi 2011)
