THE SACRAMENT OF THE EUCHARIST

1322 The holy Eucharist completes Christian initiation. Those who have been raised to the dignity of the royal priesthood by Baptism and configured more deeply to Christ by Confirmation participate with the whole community in the Lord's own sacrifice by means of the Eucharist.

1323 "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.'"¹³⁵

I. THE EUCHARIST - SOURCE AND SUMMIT OF ECCLESIAL LIFE

1324 The Eucharist is "the source and summit of the Christian life."¹³⁶ "The other sacraments, and indeed all ecclesiastical ministries and works of the apostolate, are bound up with the Eucharist and are oriented toward it. For in the blessed Eucharist is contained the whole spiritual good of the Church, namely Christ himself, our Pasch."¹³⁷

1325 "The Eucharist is the efficacious sign and sublime cause of that communion in the divine life and that unity of the People of God by which the Church is kept in being. It is the culmination both of God's action sanctifying the world in Christ and of the worship men offer to Christ and through him to the Father in the Holy Spirit."¹³⁸

1326 Finally, by the Eucharistic celebration we already unite ourselves with the heavenly liturgy and anticipate eternal life, when God will be all in all.¹³⁹

1327 In brief, the Eucharist is the sum and summary of our faith: "Our way of thinking is attuned to the Eucharist, and the Eucharist in turn confirms our way of thinking."¹⁴⁰

II. WHAT IS THIS SACRAMENT CALLED?

1328 The inexhaustible richness of this sacrament is expressed in the different names we give it. Each name evokes certain aspects of it. It is called:

Eucharist, because it is an action of thanksgiving to God. The Greek words eucharistein¹⁴¹ and eulogein¹⁴² recall the Jewish blessings that proclaim - especially during a meal - God's works: creation, redemption, and sanctification.

1329 The Lord's Supper, because of its connection with the supper which the Lord took with his disciples on the eve of his Passion and because it anticipates the wedding feast of the Lamb in the heavenly Jerusalem.¹⁴³

The Breaking of Bread, because Jesus used this rite, part of a Jewish meat when as master of the table he blessed and distributed the bread,¹⁴⁴ above all at the Last Supper.¹⁴⁵ It is by this action that his disciples will recognize him after his Resurrection,¹⁴⁶ and it is this expression that the first Christians will use to designate their Eucharistic assemblies;¹⁴⁷ by doing so they signified that all who eat the one broken bread, Christ, enter into communion with him and form but one body in him.¹⁴⁸

The Eucharistic assembly (synaxis), because the Eucharist is celebrated amid the assembly of the faithful, the visible expression of the Church.¹⁴⁹

1330 The memorial of the Lord's Passion and Resurrection.

The Holy Sacrifice, because it makes present the one sacrifice of Christ the Savior and includes the Church's offering. The terms holy sacrifice of the Mass, "sacrifice of praise," spiritual sacrifice, pure and holy sacrifice are also used,¹⁵⁰ since it completes and surpasses all the sacrifices of the Old Covenant.

The Holy and Divine Liturgy, because the Church's whole liturgy finds its center and most intense expression in the celebration of this sacrament; in the same sense we also call its celebration the Sacred Mysteries. We speak of the Most Blessed Sacrament because it is the Sacrament of sacraments. The Eucharistic species reserved in the tabernacle are designated by this same name.

1331 Holy Communion, because by this sacrament we unite ourselves to Christ, who makes us sharers in his Body and Blood to form a single body.¹⁵¹ We also call it: the holy things (ta hagia; sancta)¹⁵² - the first meaning of the phrase "communion of saints" in the Apostles' Creed - the bread of angels, bread from heaven, medicine of immortality,¹⁵³ viaticum. . . .

1332 Holy Mass (Missa), because the liturgy in which the mystery of salvation is accomplished concludes with the sending forth (missio) of the faithful, so that they may fulfill God's will in their daily lives.
