At the Last Supper, Jesus instituted the Eucharist, the gift of his Body and Blood that perpetuates his sacrifice on the Cross through the ages. He entrusts to the Church the memorial of his death and resurrection in this Sacrament: a sign of unity and a bond of charity. When the Church celebrates the Eucharist, it commemorates Christ's Passover and the sacrifice offered once and for all on the cross. The Eucharist makes God's saving actions in Jesus Christ ever-present for every age of the Church.
