At the Last Supper, on the night he was betrayed, our Savior instituted the Eucharistic sacrifice of his Body and Blood. This he did in order to perpetuate the sacrifice of the cross throughout the ages until he should come again, and so to entrust to his beloved Spouse, the Church, a memorial of his death and resurrection: a sacrament of love, a sign of unity, a bond of charity, a Paschal banquet "in which Christ is consumed, the mind is filled with grace, and a pledge of future glory is given to us."
- Catechism of the Catholic Church
As Catholics, we believe the Mass and the Eucharist are the "source and summit of the Christian life." We can worship God in a variety of ways, but the supreme act of communal worship is the Divine Liturgy, also known as the Mass. Learn more about the parts of the Mass here.
