The Eucharist is the very core of Catholicism, the heart and the summit of the Church's life. The Eucharist is the Most Holy Sacrament, the source of our communion with Christ and one another.

At the Last Supper, Christ instituted the Eucharistic sacrifice as He took bread and wine and offered them to his Apostles as his own Body and Blood, telling them "...do this in memory of me." Christ instituted the Eucharist as the memorial of his death and Resurrection. It is the firm belief of Catholics that as bread and wine are consecrated by a priest during Mass that they actually become through the process of transubstantiation the Body, Blood, Soul and Divinity of Our Lord and Savior. Because Christ has said "...he who eats my flesh and drinks my blood has eternal life..." it makes clear how important receiving the Eucharist is to our spiritual lives and progress. The Eucharist unites us to Christ and at the same time cleanses us from past sins and helps preserve us from future sins.
