C. Liturgy of the Eucharist

48. At the last supper Christ instituted the sacrifice and paschal meal that make the sacrifice of the cross to be continuously present in the Church, when the priest, representing Christ the Lord, carries out what the Lord did and handed over to his disciples to do in his memory.⁴⁰

Christ took the bread and the cup and gave thanks; he broke the bread and gave it to his disciples, saying: "Take and eat, this is my body." Giving the cup, he said: "Take and drink, this is the cup of my blood. Do this in memory of me." Accordingly, the Church has planned the celebration of the eucharistic liturgy around the parts corresponding to these words and actions of Christ:

1. In the preparation of the gifts, the bread and the wine with water are brought to the altar, that is, the same elements that Christ used.

2. In the eucharistic prayer thanks is given to God for the whole work of salvation and the gifts of bread and wine become the body and blood of Christ.

3. Through the breaking of the one bread the unity of the faithful is expressed and through communion they receive the Lord's body and blood in the same way the apostles received them from Christ's own hands.

PREPARATION OF THE GIFTS

49. At the beginning of the liturgy of the eucharist the gifts, which will become Christ's body and blood, are brought to the altar.

First the altar, the Lord's table, which is the center of the whole eucharistic liturgy,⁴¹ is prepared: the corporal, purificator, missal, and chalice are placed on it (unless the chalice is prepared at a side table).

The gifts are then brought forward. It is desirable for the faithful to present the bread and wine, which are accepted by the priest or deacon at a convenient place. The gifts are placed on the altar to the accompaniment of the prescribed texts. Even though the faithful no longer, as in the past, bring the bread and wine for the liturgy from their homes, the rite of carrying up the gifts retains the same spiritual value and meaning.

This is also the time to receive money or other gifts for the church or the poor brought by the faithful or collected at the Mass. These are to be put in a suitable place but not on the altar.

50. The procession bringing the gifts is accompanied by the presentation song, which continues at least until the gifts have been placed on the altar. The rules for this song are the same as those for the entrance song (no. 26). If it is not sung, the presentation antiphon is omitted.

51. The gifts on the altar and the altar itself may be incensed. This is a symbol of the Church's offering and prayer going up to God. Afterward the deacon or other minister may incense the priest and the people.

52. The priest then washes his hands as an expression of his desire to be cleansed within.

53. Once the gifts have been placed on the altar and the accompanying rites completed, the preparation of the gifts comes to an end through the invitation to pray with the priest and the prayer over the gifts, which are a preparation for the eucharistic prayer.

EUCHARISTIC PRAYER

54. Now the center and summit of the entire celebration begins: the eucharistic prayer, a prayer of thanksgiving and sanctification. The priest invites the people to lift up their hearts to the Lord in prayer and thanks; he unites them with himself in the prayer he addresses in their name to the Father through Jesus Christ. The meaning of the prayer is that the entire congregation joins itself to Christ in acknowledging the great things God has done and in offering the sacrifice.

55. The chief elements making up the eucharistic prayer are these:

a. Thanksgiving (expressed especially in the preface): in the name of the entire people of God, the priest praises the Father and gives thanks to him for the whole work of salvation or for some special aspect of it that corresponds to the day, feast, or season.

b. Acclamation: joining with the angels, the congregation sings or recites the «Sanctus» This acclamation is an intrinsic part of the eucharistic prayer and all the people join with the priest in singing or reciting it.

c. Epiclesis: in special invocations the Church calls on God's power and asks that the gifts offered by human hands be consecrated, that is, become Christ's body and blood, and that the victim to be received in communion be the source of salvation for those who will partake.

d. Institution narrative and consecration: in the words and actions of Christ, that sacrifice is celebrated which he himself instituted at the Last Supper, when, under the appearances of bread and wine, he offered his body and blood, gave them to his apostles to eat and drink, then commanded that they carry on this mystery.

e. Anamnesis: in fulfillment of the command received from Christ through the apostles, the Church keeps his memorial by recalling especially his passion, resurrection, and ascension.

f. Offering: in this memorial, the Church - and in particular the Church here and now assembled - offers the spotless victim to the Father in the Holy Spirit. The Church's intention is that the faithful not only offer this victim but also learn to offer themselves and so to surrender themselves, through Christ the Mediator, to an ever more complete union with the Father and with each other, so that at last God may be all in all.⁴²

g. Intercessions: the intercessions make it clear that the eucharist is celebrated in communion with the entire Church of heaven and earth and that the offering is made for the Church and all its members, living and dead, who are called to share in the salvation and redemption purchased by Christ's body and blood.

h. Final doxology: the praise of God is expressed in the doxology, to which the people's acclamation is an assent and a conclusion.

The eucharistic prayer calls for all to listen in silent reverence, but also to take part through the acclamations for which the rite makes provision.

COMMUNION RITE

56. Since the eucharistic celebration is the paschal meal, it is right that the faithful who are properly disposed receive the Lord's body and blood as spiritual food as he commanded.⁴³ This is the purpose of the breaking of bread and the other preparatory rites that lead directly to the communion of the people:

a. Lord's Prayer: this is a petition both for daily food, which for Christians means also the eucharistic bread, and for the forgiveness of sin, so that what is holy may be given to those who are holy. The priest offers the invitation to pray, but all the faithful say the prayer with him; he alone adds the embolism, «Deliver us», which the people conclude with a doxology. The embolism, developing the last petition of the Lord's Prayer, begs on behalf of the entire community of the faithful deliverance from the power of evil. The invitation, the prayer itself, the embolism, and the people's doxology are sung or are recited aloud.

b. Rite of peace: before they share in the same bread, the faithful implore peace and unity for the Church and for the whole human family and offer some sign of their love for one another.

The form the sign of peace should take is left to the conference of bishops to determine, in accord with the culture and customs of the people.

c. Breaking of the bread: in apostolic times this gesture of Christ at the last supper gave the entire eucharistic action its name. This rite is not simply functional, but is a sign that in sharing in the one bread of life which is Christ we who are many are made one body (see 1 Cor 10:17).

d. Commingling: the celebrant drops a part of the host into the chalice.

e. «Agnus Dei»: during the breaking of the bread and the commingling, the «Agnus Dei» is as a rule sung by the choir or cantor with the congregation responding; otherwise it is recited aloud. This invocation may be repeated as often as necessary to accompany the breaking of the bread. The final reprise concludes with the words, «grant us peace».

f. Personal preparation of the priest: the priest prepares himself by the prayer, said softly, that he may receive Christ's body and blood to good effect. The faithful do the same by silent prayer.

g The priest then shows the eucharistic bread for communion to the faithful and with them recites the prayer of humility in words from the Gospels.

h. It is most desirable that the faithful receive the Lord's body from hosts consecrated at the same Mass and that, in the instances when it is permitted, they share in the chalice. Then even through the signs communion will stand out more clearly as a sharing in the sacrifice actually being celebrated.⁴⁴

i. During the priest's and the faithful's reception of the sacrament the communion song is sung. Its function is to express outwardly the communicants' union in spirit by means of the unity of their voices, to give evidence of joy of heart, and to make the procession to receive Christ's body more fully an act of community. The song begins when the priest takes communion and continues for as long as seems appropriate while the faithful receive Christ's body. But the communion song should be ended in good time whenever there is to be a hymn after communion.

An antiphon from the «Graduale Romanum» may also be used, with or without the psalm, or an antiphon with psalm from «The Simple Gradual» or another suitable song approved by the conference of bishops. It is sung by the choir alone or by the choir or cantor with the congregation.

If there is no singing, the communion antiphon in the Missal is recited either by the people, by some of them, or by a reader. Otherwise the priest himself says it after he has received communion and before he gives communion to the faithful.

j. After communion, the priest and people may spend some time in silent prayer. If desired, a hymn, psalm, or other song of praise may be sung by the entire congregation.

k. In the prayer after communion, the priest petitions for the effects of the mystery just celebrated and by their acclamation, Amen, the people make the prayer their own.
