The Eucharist, also referred to as Holy Communion, is the central part of the Mass for Catholics. It is at this time that the bread and wine become the Body and Blood of Our Lord, Jesus Christ. As Catholics, we believe that the Eucharist is not merely a sign or a symbol, but that Jesus is truly present. Receiving the Eucharist changes us. It represents the unity of the community and serves to strengthen the Body of Christ.
