The Sacrament of the Eucharist is both a sacrifice and a meal. It has its origin in the Last Supper when, on the night that he was betrayed, Jesus instituted the Eucharistic Sacrifice of His Body and Blood. He did this in order to perpetuate the sacrifice of the cross throughout the ages until He comes again. We do this in memory of Jesus because he told us to. Remembering is not just about looking back to a past event that happened long ago, but participating in that event in a real, although invisible way. The Eucharist is called the “Source and Summit” of the Catholic faith because in the Eucharist, we encounter the Real Presence of Jesus: His Body and Blood present under the appearance of bread and wine.
