YOUCAT Question n. 212 - Part II. What names are there for Jesus’ meal with us, and what do they mean?

(Youcat answer - repeated) The different names indicate the unfathomable richness of this mystery: the Holy Sacrifice, Holy Mass, the Sacrifice of the Mass—the Lord’s Supper—the Breaking of Bread—the Eucharistic assembly—the memorial of the Lord’s Passion, death, and Resurrection—the Holy and Divine Liturgy, the Sacred Mysteries—Holy Communion.

A deepening through CCC

(CCC 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 (Heb 13:15; cf. 1 Pet 25; Ps 116:13, 17; Mal 1:11), 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.  

Reflecting and meditating 

(Youcat comment b) The early Church called their liturgical feasts “the breaking of bread”. Eucharistic assembly: The celebration of the Lord’s Supper is also an assembly of “thanksgiving”, in which the Church finds her visible xpression. Memorial of the Lord’s Passion, death, and Resurrection : In the celebration of the Eucharist, the congregation does not celebrate itself; rather it discovers and celebrates again and again the presence of Christ’s saving passage through suffering and death to life. Holy and Divine Liturgy, Sacred Mysteries : In the celebration of the Eucharist, the Church in heaven and on earth unite in one feast. Because the Eucharistic Gifts in which Christ is present are, so to speak, the holiest thing in the world, we also speak about the Most Blessed Sacrament. Holy Communion: Because we unite ourselves with Christ at Holy Mass, and through him are united with one another, we speak about Holy Communion (communio = fellowship).

(CCC Comment)

(CCC 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 (Cf. 1 Cor 10: 16-17). We also call it: the holy things (ta hagia; sancta) (Apostolic Constitutions 8, 13,12: PG 1, 1108; Didache 9, 5; 10:6: SCh: 248, 176-178) - the first meaning of the phrase "communion of saints" in the Apostles' Creed - the bread of angels, bread from heaven, medicine of immortality (St. Ignatius of Antioch, Ad Eph. 20, 2 SCh 10, 76), viaticum.... (CCC 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.
