Catholics believe the Eucharist, or Communion, is both
a sacrifice and a meal. We believe in the real presence of Jesus, who died for our sins. As we receive Christ's Body and Blood, we also are nourished spiritually and brought closer to God.

The Eucharist was foreshadowed in the Old Covenant
above all in the annual Passover meal celebrated every year by the Jews with unleavened bread to commemorate their hasty, liberating departure from Egypt.

Jesus foretold it in his teaching and he instituted it when he celebrated the Last Supper with his apostles in a Passover meal.

The Church, faithful to the command of her Lord,
“Do this in memory of me” (1 Corinthians 11:24),
has always celebrated the Eucharist, especially on Sunday, the day of the Resurrection of Jesus.
