The Eucharist is the heart and the summit of the Church’s life, for in it Christ associates his Church and all her members with his sacrifice of praise and thanksgiving offered once for all on the cross to his Father; by this sacrifice he pours out the graces of salvation on his Body which is the Church” Catechism of the Catholic Church 1407
The Eucharist is the memorial of Christ’s Passover, that is, of the work of salvation accomplished by the life, death, and resurrection of Christ, a work made present by the liturgical action.
Catechism of the Catholic Church 1409
The Eucharist is another name for Holy Communion. The term comes from the Greek by way of Latin, and it means "thanksgiving." It is used in three ways: first, to refer to the Real Presence of Christ; second, to refer to Christ's continuing action as High Priest (He "gave thanks" at the Last Supper, which began the consecration of the bread and wine); and third, to refer to the Sacrament of Holy Communion itself.
Jesus said: “I am the living bread that came down from heaven; if any one eats of this bread, he will live for ever; . . . he who eats my flesh and drinks my blood has eternal life and . . . abides in me, and I in him” (Jn 6:51, 54, 56).
