Chapter II

The Structure of the Mass, Its Elements and Its Parts

27. At Mass—that is, the Lord's Supper—the People of God is called together, with a priest presiding and acting in the person of Christ, to celebrate the memorial of the Lord, the Eucharistic Sacrifice.³⁷ For this reason Christ's promise applies in an outstanding way to such a local gathering of the holy Church: "Where two or three are gathered in my name, there am I in their midst" (Mt 18:20). For in the celebration of Mass, in which the Sacrifice of the Cross is perpetuated,³⁸ Christ is really present in the very liturgical assembly gathered in his name, in the person of the minister, in his word, and indeed substantially and continuously under the eucharistic species.³⁹

28. The Mass is made up, as it were, of two parts: the Liturgy of the Word and the Liturgy of the Eucharist. These, however, are so closely interconnected that they form but one single act of worship.⁴⁰ For in the Mass the table both of God's word and of Christ's Body is prepared, from which the faithful may be instructed and refreshed.⁴¹ There are also certain rites that open and conclude the celebration.

II. The Different Elements of the Mass

Reading and Explaining the Word of God

29. When the Sacred Scriptures are read in the Church, God himself speaks to his people, and Christ, present in his own word, proclaims the Gospel.

Therefore, all must listen with reverence to the readings from God's word, for they make up an element of greatest importance in the Liturgy. Although in the readings from Sacred Scripture God's word is addressed to all people of every era and is understandable to them, nevertheless, a fuller understanding and a greater effectiveness of the word is fostered by a living commentary on the word, that is, the homily, as part of the liturgical action.⁴²

The Prayers and Other Parts Pertaining to the Priest

30. Among the parts assigned to the priest, the foremost is the Eucharistic Prayer, which is the high point of the entire celebration. Next are the orations: that is to say, the collect, the prayer over the offerings, and the prayer after Communion. These prayers are addressed to God in the name of the entire holy people and all present, by the priest who presides over the assembly in the person of Christ.⁴³ It is with good reason, therefore, that they are called the "presidential prayers."

31. It is also up to the priest, in the exercise of his office of presiding over the gathered assembly, to offer certain explanations that are foreseen in the rite itself. Where it is indicated in the rubrics, the celebrant is permitted to adapt them somewhat in order that they respond to the understanding of those participating. However, he should always take care to keep to the sense of the text given in the Missal and to express them succinctly. The presiding priest is also to direct the word of God and to impart the final blessing. In addition, he may give the faithful a very brief introduction to the Mass of the day (after the initial Greeting and before the Act of Penitence), to the Liturgy of the Word (before the readings), and to the Eucharistic Prayer (before the Preface), though never during the Eucharistic Prayer itself; he may also make concluding comments to the entire sacred action before the dismissal.

32. The nature of the "presidential" texts demands that they be spoken in a loud and clear voice and that everyone listen with attention.⁴⁴ Thus, while the priest is speaking these texts, there should be no other prayers or singing, and the organ or other musical instruments should be silent.

33. The priest, in fact, as the one who presides, prays in the name of the Church and of the assembled community; but at times he prays only in his own name, asking that he may exercise his ministry with greater attention and devotion. Prayers of this kind, which occur before the reading of the Gospel, at the Preparation of the Gifts, and also before and after the Communion of the priest, are said quietly.

The Other Formulas in the Celebration

34. Since the celebration of Mass by its nature has a "communitarian" character,⁴⁵ both the dialogues between the priest and the faithful gathered together and the acclamations are of great significance;⁴⁶ in fact, they are not simply outward signs of communal celebration but foster and bring about communion between priest and people.

35. The acclamations and the responses of the faithful to the priest's greetings and prayers constitute that level of active participation that the gathered faithful are to contribute in every form of the Mass, so that the action of the entire community may be clearly expressed and fostered.⁴⁷

36. Other parts, very useful for expressing and fostering the faithful's active participation, that are assigned to the whole assembly that is called together include especially the Act of Penitence, the Profession of Faith, the Prayer of the Faithful, and the Lord's Prayer.

37. Finally, concerning the other formulas,:

Some constitute an independent rite or act, such as the Gloria, the responsorial Psalm, the Alleluia and verse before the Gospel, the Sanctus, the Memorial Acclamation, and the cantus post communionem;
Others accompany another rite, such as the chants at the Entrance, at the Offertory, at the fraction (Agnus Dei), and at Communion.

The Vocal Expression of the Different Texts

38. In texts that are to be spoken in a loud and clear voice, whether by the priest or the deacon, or by the lector, or by all, the tone of voice should correspond to the genre of the text itself, that is, depending upon whether it is a reading, a prayer, a commentary, an acclamation, or a sung text; the tone should also be suited to the form of celebration and to the solemnity of the gathering. Consideration should also be given to the idiom of different languages and the culture of different peoples.

In the rubrics and in the norms that follow, words such as "say" and "proclaim" are to be understood of both singing and reciting, according to the principles just stated above.

The Importance of Singing

39. The Christian faithful who gather together as one to await the Lord's coming are instructed by the Apostle Paul to sing together psalms, hymns, and spiritual songs (cf. Col 3:16). Singing is the sign of the heart's joy (cf. Acts 2:46). Thus Saint Augustine says rightly, "Singing is for one who loves."⁴⁸ There is also the ancient proverb: "One who sings well prays twice."

40. Great importance should therefore be attached to the use of singing in the celebration of the Mass, with due consideration for the culture of the people and abilities of each liturgical assembly. Although it is not always necessary (e.g., in weekday Masses) to sing all the texts that are of themselves meant to be sung, every care should be taken that singing by the ministers and the people is not absent in celebrations that occur on Sundays and on holy days of obligation.

In the choosing of the parts actually to be sung, however, preference should be given to those that are of greater importance and especially to those to be sung by the priest or the deacon or the lector, with the people responding, or by the priest and people together.⁴⁹

41. All other things being equal, Gregorian chant holds pride of place because it is proper to the Roman Liturgy. Other types of sacred music, in particular polyphony, are in no way excluded, provided that they correspond to the spirit of the liturgical action and that they foster the participation of all the faithful.⁵⁰

Since faithful from different countries come together ever more frequently, it is fitting that they know how to sing together at least some parts of the Ordinary of the Mass in Latin, especially the Creed and the Lord's Prayer, set to the simpler melodies.⁵¹

Movements and Posture

42. The gestures and posture of the priest, the deacon, and the ministers, as well as those of the people, ought to contribute to making the entire celebration resplendent with beauty and noble simplicity, so that the true and full meaning of the different parts of the celebration is evident and that the participation of all is fostered.⁵² Therefore, attention should be paid to what is determined by this General Instruction and the traditional practice of the Roman Rite and to what serves the common spiritual good of the People of God, rather than private inclination or arbitrary choice.

A common posture, to be observed by all participants, is a sign of the unity of the members of the Christian community gathered for the Sacred Liturgy: it both expresses and fosters the intention and spiritual attitude of the participants.

43. The faithful should stand from the beginning of the Entrance chant, or while the priest approaches the altar, until the end of the Collect; for the Alleluia chant before the Gospel; while the Gospel itself is proclaimed; during the Profession of Faith and the Prayer of the Faithful; from the invitation, Orate, fratres (Pray, brethren), before the prayer over the offerings until the end of Mass, except at the places indicated below.

They should, however, sit while the readings before the Gospel and the responsorial Psalm are proclaimed and for the homily and while the Preparation of the Gifts at the Offertory is taking place; and, as circumstances allow, they may sit or kneel while the period of sacred silence after Communion is observed.

In the dioceses of the United States of America, they should kneel beginning after the singing or recitation of the Sanctus until after the Amen of the Eucharistic Prayer, except when prevented on occasion by reasons of health, lack of space, the large number of people present, or some other good reason. Those who do not kneel ought to make a profound bow when the priest genuflects after the consecration. The faithful kneel after the Agnus Dei unless the Diocesan Bishop determines otherwise.⁵³

With a view to a uniformity in gestures and postures during one and the same celebration, the faithful should follow the directions which the deacon, lay minister, or priest gives according to whatever is indicated in the Missal.

44. Among gestures included are also actions and processions: of the priest going with the deacon and ministers to the altar; of the deacon carrying the Evangeliary or Book of the Gospels to the ambo before the proclamation of the Gospel; of the faithful presenting the gifts and coming forward to receive Communion. It is appropriate that actions and processions of this sort be carried out with decorum while the chants proper to them occur, in keeping with the norms prescribed for each.

Silence

45. Sacred silence also, as part of the celebration, is to be observed at the designated times.⁵⁴ Its purpose, however, depends on the time it occurs in each part of the celebration. Thus within the Act of Penitence and again after the invitation to pray, all recollect themselves; but at the conclusion of a reading or the homily, all meditate briefly on what they have heard; then after Communion, they praise and pray to God in their hearts.

Even before the celebration itself, it is commendable that silence to be observed in the church, in the sacristy, in the vesting room, and in adjacent areas, so that all may dispose themselves to carry out the sacred action in a devout and fitting manner.

III. The Individual Parts of the Mass

A. THE INTRODUCTORY RITES

46. The rites preceding the Liturgy of the Word, namely the Entrance, Greeting, Act of Penitence, Kyrie, Gloria, and Collect, have the character of a beginning, introduction, and preparation.
Their purpose is to ensure that the faithful who come together as one establish communion and dispose themselves to listen properly to God's word and to celebrate the Eucharist worthily.
In certain celebrations that are combined with Mass according to the norms of the liturgical books, the Introductory Rites are omitted or performed in a particular way.

The Entrance

47. After the people have gathered, the Entrance chant begins as the priest enters with the deacon and ministers. The purpose of this chant is to open the celebration, foster the unity of those who have been gathered, introduce their thoughts to the mystery of the liturgical season or festivity, and accompany the procession of the priest and ministers.

48. The singing at this time is done either alternately by the choir and the people or in a similar way by the cantor and the people, or entirely by the people, or by the choir alone. In the dioceses of the United States of America there are four options for the Entrance Chant: (1) the antiphon from the Roman Missal or the Psalm from the Roman Gradual as set to music there or in another musical setting; (2) the seasonal antiphon and Psalm of the Simple Gradual; (3) a song from another collection of psalms and antiphons, approved by the Conference of Bishops or the Diocesan Bishop, including psalms arranged in responsorial or metrical forms; (4) a suitable liturgical song similarly approved by the Conference of Bishops or the Diocesan Bishop.⁵⁵

If there is no singing at the entrance, the antiphon in the Missal is recited either by the faithful, or by some of them, or by a lector; otherwise, it is recited by the priest himself, who may even adapt it as an introductory explanation (cf. above, no. 31).

Greeting of the Altar and of the People Gathered Together

49. When they reach the sanctuary, the priest, the deacon, and the ministers reverence the altar with a profound bow.

As an expression of veneration, moreover, the priest and deacon then kiss the altar itself; as the occasion suggests, the priest also incenses the cross and the altar.

50. When the Entrance chant is concluded, the priest stands at the chair and, together with the whole gathering, makes the Sign of the Cross. Then he signifies the presence of the Lord to the community gathered there by means of the Greeting. By this Greeting and the people's response, the mystery of the Church gathered together is made manifest.

After the greeting of the people, the priest, the deacon, or a lay minister may very briefly introduce the faithful to the Mass of the day.

The Act of Penitence

51. Then the priest invites those present to take part in the Act of Penitence, which, after a brief pause for silence, the entire community carries out through a formula of general confession. The rite concludes with the priest's absolution, which, however, lacks the efficacy of the Sacrament of Penance.

On Sundays, especially in the Season of Easter, in place of the customary Act of Penitence, from time to time the blessing and sprinkling of water to recall Baptism may take place.⁵⁶

The Kyrie Eleison

52. After the Act of Penitence, the Kyrie is always begun, unless it has already been included as part of the Act of Penitence. Since it is a chant by which the faithful acclaim the Lord and implore his mercy, it is ordinarily done by all, that is, by the people and with the choir or cantor having a part in it.

As a rule, each acclamation is sung or said twice, though it may be repeated several times, by reason of the character of the various languages, as well as of the artistry of the music or of other circumstances. When the Kyrie is sung as a part of the Act of Penitence, a trope may precede each acclamation.

The Gloria

53. The Gloria is a very ancient and venerable hymn in which the Church, gathered together in the Holy Spirit, glorifies and entreats God the Father and the Lamb. The text of this hymn may not be replaced by any other text. The Gloria is intoned by the priest or, if appropriate, by a cantor or by the choir; but it is sung either by everyone together, or by the people alternately with the choir, or by the choir alone. If not sung, it is to be recited either by all together or by two parts of the congregation responding one to the other.

It is sung or said on Sundays outside the Seasons of Advent and Lent, on solemnities and feasts, and at special celebrations of a more solemn character.

The Collect

54. Next the priest invites the people to pray. All, together with the priest, observe a brief silence so that they may be conscious of the fact that they are in God's presence and may formulate their petitions mentally. Then the priest says the prayer which is customarily known as the Collect and through which the character of the celebration is expressed. In accordance with the ancient tradition of the Church, the collect prayer is usually addressed to God the Father, through Christ, in the Holy Spirit,⁵⁷ and is concluded with a trinitarian, that is to say the longer ending, in the following manner:

If the prayer is directed to the Father: Per Dominum nostrum Iesum Christum Filium tuum, qui tecum vivit et regnat in unitate Spiritus Sancti, Deus, per omnia saecula saeculorum;
If it is directed to the Father, but the Son is mentioned at the end: Qui tecum vivit et regnat in unitate Spiritus Sancti, Deus, per omnia saecula saeculorum;
If it is directed to the Son: Qui vivis et regnas cum Deo Patre in unitate Spiritus Sancti, Deus, per omnia saecula saeculorum.

The people, uniting themselves to this entreaty, make the prayer their own with the acclamation Amen.

There is always only one collect used in a Mass.

B. THE LITURGY OF THE WORD

55. The main part of the Liturgy of the Word is made up of the readings from Sacred Scripture together with the chants occurring between them. The homily, Profession of Faith, and Prayer of the Faithful, however, develop and conclude this part of the Mass. For in the readings, as explained by the homily, God speaks to his people,⁵⁸ opening up to them the mystery of redemption and salvation and offering them spiritual nourishment; and Christ himself is present in the midst of the faithful through his word.⁵⁹ By their silence and singing the people make God's word their own, and they also affirm their adherence to it by means of the Profession of Faith. Finally, having been nourished by it, they pour out their petitions in the Prayer of the Faithful for the needs of the entire Church and for the salvation of the whole world.

Silence

56. The Liturgy of the Word is to be celebrated in such a way as to promote meditation, and so any sort of haste that hinders recollection must clearly be avoided. During the Liturgy of the Word, it is also appropriate to include brief periods of silence, accommodated to the gathered assembly, in which, at the prompting of the Holy Spirit, the word of God may be grasped by the heart and a response through prayer may be prepared. It may be appropriate to observe such periods of silence, for example, before the Liturgy of the Word itself begins, after the first and second reading, and lastly at the conclusion of the homily.⁶⁰

The Biblical Readings

57. In the readings, the table of God's word is prepared for the faithful, and the riches of the Bible are opened to them.⁶¹ Hence, it is preferable to maintain the arrangement of the biblical readings, by which light is shed on the unity of both Testaments and of salvation history. Moreover, it is unlawful to substitute other, non-biblical texts for the readings and responsorial Psalm, which contain the word of God.⁶²

58. In the celebration of the Mass with a congregation, the readings are always proclaimed from the ambo.

59. By tradition, the function of proclaiming the readings is ministerial, not presidential. The readings, therefore, should be proclaimed by a lector, and the Gospel by a deacon or, in his absence, a priest other than the celebrant. If, however, a deacon or another priest is not present, the priest celebrant himself should read the Gospel. Further, if another suitable lector is also not present, then the priest celebrant should also proclaim the other readings.

After each reading, whoever reads gives the acclamation, to which the gathered people reply, honoring the word of God that they have received in faith and with grateful hearts.

60. The reading of the Gospel is the high point of the Liturgy of the Word. The Liturgy itself teaches that great reverence is to be shown to it by setting it off from the other readings with special marks of honor: whether the minister appointed to proclaim it prepares himself by a blessing or prayer; or the faithful, standing as they listen to it being read, through their acclamations acknowledge and confess Christ present and speaking to them; or the very marks of reverence are given to the Book of the Gospels.

The Responsorial Psalm

61. After the first reading comes the responsorial Psalm, which is an integral part of the Liturgy of the Word and holds great liturgical and pastoral importance, because it fosters meditation on the word of God.

The responsorial Psalm should correspond to each reading and should, as a rule, be taken from the Lectionary.

It is preferable that the responsorial Psalm be sung, at least as far as the people's response is concerned. Hence, the psalmist, or the cantor of the Psalm, sings the verses of the Psalm from the ambo or another suitable place. The entire congregation remains seated and listens but, as a rule, takes part by singing the response, except when the Psalm is sung straight through without a response. In order, however, that the people may be able to sing the Psalm response more readily, texts of some responses and Psalms have been chosen for the various seasons of the year or for the various categories of Saints. These may be used in place of the text corresponding to the reading whenever the Psalm is sung. If the Psalm cannot be sung, then it should be recited in such a way that it is particularly suited to fostering meditation on the word of God.

In the dioceses of the United States of America, the following may also be sung in place of the Psalm assigned in the Lectionary for Mass: either the proper or seasonal antiphon and Psalm from the Lectionary, as found either in the Roman Gradual or Simple Gradual or in another musical setting; or an antiphon and Psalm from another collection of the psalms and antiphons, including psalms arranged in metrical form, providing that they have been approved by the United States Conference of Catholic Bishops or the Diocesan Bishop. Songs or hymns may not be used in place of the responsorial Psalm.

62. After the reading that immediately precedes the Gospel, the Alleluia or another chant indicated by the rubrics is sung, as required by the liturgical season. An acclamation of this kind constitutes a rite or act in itself, by which the assembly of the faithful welcomes and greets the Lord who is about to speak to them in the Gospel and professes their faith by means of the chant. It is sung by all while standing and is led by the choir or a cantor, being repeated if this is appropriate. The verse, however, is sung either by the choir or by the cantor.

The Alleluia is sung in every season other than Lent. The verses are taken from the Lectionary or the Graduale.
During Lent, in place of the Alleluia, the verse before the Gospel is sung, as indicated in the Lectionary. It is also permissible to sing another psalm or tract, as found in the Graduale.

63. When there is only one reading before the Gospel,

During a season when the Alleluia is to be said, either the Alleluia Psalm or the responsorial Psalm followed by the Alleluia with its verse may be used;
During the season when the Alleluia is not to be said, either the psalm and the verse before the Gospel or the psalm alone may be used;
The Alleluia or verse before the Gospel may be omitted if they are not sung.

64. The Sequence, which is optional except on Easter Sunday and on Pentecost Day, is sung before the Alleluia.

The Homily

65. The homily is part of the Liturgy and is strongly recommended,⁶³ for it is necessary for the nurturing of the Christian life. It should be an exposition of some aspect of the readings from Sacred Scripture or of another text from the Ordinary or from the Proper of the Mass of the day and should take into account both the mystery being celebrated and the particular needs of the listeners.⁶⁴

66. The Homily should ordinarily be given by the priest celebrant himself. He may entrust it to a concelebrating priest or occasionally, according to circumstances, to the deacon, but never to a lay person.⁶⁵ In particular cases and for a just cause, the homily may even be given by a Bishop or a priest who is present at the celebration but cannot concelebrate.

There is to be a homily on Sundays and holy days of obligation at all Masses that are celebrated with the participation of a congregation; it may not be omitted without a serious reason. It is recommended on other days, especially on the weekdays of Advent, Lent, and the Easter Season, as well as on other festive days and occasions when the people come to church in greater numbers.⁶⁶

After the homily a brief period of silence is appropriately observed.

The Profession of Faith

67. The purpose of the Symbolum or Profession of Faith, or Creed, is that the whole gathered people may respond to the word of God proclaimed in the readings taken from Sacred Scripture and explained in the homily and that they may also call to mind and confess the great mysteries of the faith by reciting the rule of faith in a formula approved for liturgical use, before these mysteries are celebrated in the Eucharist.

68. The Creed is to be sung or said by the priest together with the people on Sundays and Solemnities. It may be said also at particular celebrations of a more solemn character.

If it is sung, it is begun by the priest or, if this is appropriate, by a cantor or by the choir. It is sung, however, either by all together or by the people alternating with the choir.

If not sung, it is to be recited by all together or by two parts of the assembly responding one to the other.

The Prayer of the Faithful
69. In the Prayer of the Faithful, the people respond in a certain way to the word of God which they have welcomed in faith and, exercising the office of their baptismal priesthood, offer prayers to God for the salvation of all. It is fitting that such a prayer be included, as a rule, in Masses celebrated with a congregation, so that petitions will be offered for the holy Church, for civil authorities, for those weighed down by various needs, for all men and women, and for the salvation of the whole world.⁶⁷

70. As a rule, the series of intentions is to be

For the needs of the Church;
For public authorities and the salvation of the whole world;
For those burdened by any kind of difficulty;
For the local community.

Nevertheless, in a particular celebration, such as Confirmation, Marriage, or a Funeral, the series of intentions may reflect more closely the particular occasion.

71. It is for the priest celebrant to direct this prayer from the chair. He himself begins it with a brief introduction, by which he invites the faithful to pray, and likewise he concludes it with a prayer. The intentions announced should be sober, be composed freely but prudently, and be succinct, and they should express the prayer of the entire community.

The intentions are announced from the ambo or from another suitable place, by the deacon or by a cantor, a lector, or one of the lay faithful.⁶⁸

The people, however, stand and give expression to their prayer either by an invocation said together after each intention or by praying in silence.

C. THE LITURGY OF THE EUCHARIST

72. At the Last Supper Christ instituted the Paschal Sacrifice and banquet by which the Sacrifice of the Cross is continuously made present in the Church whenever the priest, representing Christ the Lord, carries out what the Lord himself did and handed over to his disciples to be done in his memory.⁶⁹

For Christ took the bread and the chalice and gave thanks; he broke the bread and gave it to his disciples, saying, "Take, eat, and drink: this is my Body; this is the cup of my Blood. Do this in memory of me." Accordingly, the Church has arranged the entire celebration of the Liturgy of the Eucharist in parts corresponding to precisely these words and actions of Christ:

At the Preparation of the Gifts, the bread and the wine with water are brought to the altar, the same elements that Christ took into his hands.
In the Eucharistic Prayer, thanks is given to God for the whole work of salvation, and the offerings become the Body and Blood of Christ.
Through the fraction and through Communion, the faithful, though they are many, receive from the one bread the Lord's Body and from the one chalice the Lord's Blood in the same way the Apostles received them from Christ's own hands.

The Preparation of the Gifts

73. 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 Liturgy of the Eucharist,⁷⁰ is prepared by placing on it the corporal, purificator, Missal, and chalice (unless the chalice is prepared at the credence table).

The offerings are then brought forward. It is praiseworthy for the bread and wine to be presented by the faithful. They are then accepted at an appropriate place by the priest or the deacon and carried to the altar. Even though the faithful no longer bring from their own possessions the bread and wine intended for the liturgy as in the past, nevertheless the rite of carrying up the offerings still retains its force and its spiritual significance.

It is well also that money or other gifts for the poor or for the Church, brought by the faithful or collected in the church, should be received. These are to be put in a suitable place but away from the eucharistic table.

74. The procession bringing the gifts is accompanied by the Offertory chant (cf. above, no. 37b), which continues at least until the gifts have been placed on the altar. The norms on the manner of singing are the same as for the Entrance chant (cf. above, no. 48). Singing may always accompany the rite at the offertory, even when there is no procession with the gifts.

75. The bread and wine are placed on the altar by the priest to the accompaniment of the prescribed formulas. The priest may incense the gifts placed upon the altar and then incense the cross and the altar itself, so as to signify the Church's offering and prayer rising like incense in the sight of God. Next, the priest, because of his sacred ministry, and the people, by reason of their baptismal dignity, may be incensed by the deacon or another minister.

76. The priest then washes his hands at the side of the altar, a rite that is an expression of his desire for interior purification.

The Prayer over the Offerings

77. Once the offerings have been placed on the altar and the accompanying rites completed, the invitation to pray with the priest and the prayer over the offerings conclude the preparation of the gifts and prepare for the Eucharistic Prayer.

In the Mass, only one Prayer over the Offerings is said, and it ends with the shorter conclusion: Per Christum Dominum nostrum. If, however, the Son is mentioned at the end of this prayer, the conclusion is, Qui vivit et regnat in saecula saeculorum.

The people, uniting themselves to this entreaty, make the prayer their own with the acclamation, Amen.

The Eucharistic Prayer

78. Now the center and summit of the entire celebration begins: namely, the Eucharistic Prayer, that is, the prayer of thanksgiving and sanctification. The priest invites the people to lift up their hearts to the Lord in prayer and thanksgiving; he unites the congregation with himself in the prayer that he addresses in the name of the entire community to God the Father through Jesus Christ in the Holy Spirit. Furthermore, the meaning of the Prayer is that the entire congregation of the faithful should join itself with Christ in confessing the great deeds of God and in the offering of Sacrifice. The Eucharistic Prayer demands that all listen to it with reverence and in silence.

79. The chief elements making up the Eucharistic Prayer may be distinguished in this way:

Thanksgiving (expressed especially in the Preface): In which the priest, in the name of the entire holy people, glorifies God the Father and gives thanks for the whole work of salvation or for some special aspect of it that corresponds to the day, festivity, or season.
Acclamation: In which the whole congregation, joining with the heavenly powers, sings the Sanctus. This acclamation, which is part of the Eucharistic Prayer itself, is sung or said by all the people with the priest.
Epiclesis: In which, by means of particular invocations, the Church implores the power of the Holy Spirit that the gifts offered by human hands be consecrated, that is, become Christ's Body and Blood, and that the spotless Victim to be received in Communion be for the salvation of those who will partake of it.
Institution narrative and consecration: In which, by means of words and actions of Christ, the Sacrifice is carried out which Christ himself instituted at the Last Supper, when he offered his Body and Blood under the species of bread and wine, gave them to his Apostles to eat and drink, and left them the command to perpetuate this same mystery.
Anamnesis: In which the Church, fulfilling the command that she received from Christ the Lord through the Apostles, keeps the memorial of Christ, recalling especially his blessed Passion, glorious Resurrection, and Ascension into heaven.
Offering: By which, in this very memorial, the Church—and in particular the Church here and now gathered—offers in the Holy Spirit the spotless Victim to the Father. The Church's intention, however, is that the faithful not only offer this spotless Victim but also learn to offer themselves,⁷¹ and so day by day to be consummated, through Christ the Mediator, into unity with God and with each other, so that at last God may be all in all.⁷²
Intercessions: By which expression is given to the fact that the Eucharist is celebrated in communion with the entire Church, of heaven as well as of earth, and that the offering is made for her and for all her members, living and dead, who have been called to participate in the redemption and the salvation purchased by Christ's Body and Blood.
Final doxology: By which the glorification of God is expressed and is confirmed and concluded by the people's acclamation, Amen.

The Communion Rite

80. Since the Eucharistic Celebration is the Paschal Banquet, it is desirable that in keeping with the Lord's command, his Body and Blood should be received by the faithful who are properly disposed as spiritual food. This is the sense of the fraction and the other preparatory rites by which the faithful are led directly to Communion.

The Lord's Prayer

81. In the Lord's Prayer a petition is made for daily food, which for Christians means preeminently the eucharistic bread, and also for purification from sin, so that what is holy may, in fact, be given to those who are holy. The priest says the invitation to the prayer, and all the faithful say it with him; the priest alone adds the embolism, which the people conclude with a doxology. The embolism, enlarging upon the last petition of the Lord's Prayer itself, begs deliverance from the power of evil for the entire community of the faithful.

The invitation, the Prayer itself, the embolism, and the doxology by which the people conclude these things are sung or said aloud.

The Rite of Peace

82. The Rite of Peace follows, by which the Church asks for peace and unity for herself and for the whole human family, and the faithful express to each other their ecclesial communion and mutual charity before communicating in the Sacrament.

As for the sign of peace to be given, the manner is to be established by Conferences of Bishops in accordance with the culture and customs of the peoples. It is, however, appropriate that each person offer the sign of peace only to those who are nearest and in a sober manner.

The Fraction

83. The priest breaks the Eucharistic Bread, assisted, if the case calls for it, by the deacon or a concelebrant. Christ's gesture of breaking bread at the Last Supper, which gave the entire Eucharistic Action its name in apostolic times, signifies that the many faithful are made one body (1 Cor 10:17) by receiving Communion from the one Bread of Life which is Christ, who died and rose for the salvation of the world. The fraction or breaking of bread is begun after the sign of peace and is carried out with proper reverence, though it should not be unnecessarily prolonged, nor should it be accorded undue importance. This rite is reserved to the priest and the deacon.

The priest breaks the Bread and puts a piece of the host into the chalice to signify the unity of the Body and Blood of the Lord in the work of salvation, namely, of the living and glorious Body of Jesus Christ. The supplication Agnus Dei, is, as a rule, sung by the choir or cantor with the congregation responding; or it is, at least, recited aloud. This invocation accompanies the fraction and, for this reason, may be repeated as many times as necessary until the rite has reached its conclusion, the last time ending with the words dona nobis pacem (grant us peace).

Communion

84. The priest prepares himself by a prayer, said quietly, that he may fruitfully receive Christ's Body and Blood. The faithful do the same, praying silently.

The priest next shows the faithful the Eucharistic Bread, holding it above the paten or above the chalice, and invites them to the banquet of Christ. Along with the faithful, he then makes an act of humility using the prescribed words taken from the Gospels.

85. It is most desirable that the faithful, just as the priest himself is bound to do, receive the Lord's Body from hosts consecrated at the same Mass and that, in the instances when it is permitted, they partake of the chalice (cf. below, no. 283), so that even by means of the signs Communion will stand out more clearly as a participation in the sacrifice actually being celebrated.⁷³

86. While the priest is receiving the Sacrament, the Communion chant is begun. Its purpose is to express the communicants' union in spirit by means of the unity of their voices, to show joy of heart, and to highlight more clearly the "communitarian" nature of the procession to receive Communion. The singing is continued for as long as the Sacrament is being administered to the faithful.⁷⁴ If, however, there is to be a hymn after Communion, the Communion chant should be ended in a timely manner.

Care should be taken that singers, too, can receive Communion with ease.

87. In the dioceses of the United States of America there are four options for the Communion chant: (1) the antiphon from the Roman Missal or the Psalm from the Roman Gradual as set to music there or in another musical setting; (2) the seasonal antiphon and Psalm of the Simple Gradual; (3) a song from another collection of psalms and antiphons, approved by the United States Conference of Catholic Bishops or the Diocesan Bishop, including psalms arranged in responsorial or metrical forms; (4) a suitable liturgical song chosen in accordance with no. 86 above. This is sung either by the choir alone or by the choir or cantor with the people.

If there is no singing, however, the Communion antiphon found in the Missal may be recited either by the faithful, or by some of them, or by a lector. Otherwise the priest himself says it after he has received Communion and before he distributes Communion to the faithful.

88. When the distribution of Communion is finished, as circumstances suggest, the priest and faithful spend some time praying privately. If desired, a psalm or other canticle of praise or a hymn may also be sung by the entire congregation.

89. To bring to completion the prayer of the People of God, and also to conclude the entire Communion Rite, the priest says the Prayer after Communion, in which he prays for the fruits of the mystery just celebrated.

In the Mass only one prayer after Communion is said, which ends with a shorter conclusion; that is,

If the prayer is directed to the Father: Per Christum Dominum nostrum;
If it is directed to the Father, but the Son is mentioned at the end: Qui vivit et regnat in saecula saeculorum;
If it is directed to the Son: Qui vivis et regnas in saecula saeculorum.

The people make the prayer their own by the acclamation, Amen.

D. THE CONCLUDING RITES

90. The concluding rites consist of

Brief announcements, if they are necessary;
The priest's greeting and blessing, which on certain days and occasions is enriched and expressed in the prayer over the People or another more solemn formula;
The dismissal of the people by the deacon or the priest, so that each may go out to do good works, praising and blessing God;
The kissing of the altar by the priest and the deacon, followed by a profound bow to the altar by the priest, the deacon, and the other ministers.
