CELEBRATING THE LITURGY OF THE CHURCH

Who celebrates?

233. Who acts in the liturgy?

1135-1137
1187 

In the liturgy it is the whole Christ (Christus Totus) who acts, Head and Body. As our High Priest he celebrates with his body, which is the Church in heaven and on earth.

234. Who celebrates the heavenly liturgy?

1138-1139 

The heavenly liturgy is celebrated by the angels, by the saints of the Old and New Testament, particularly the Mother of God, by the Apostles, by the martyrs, and by the “great multitude which no one could number from every nation, race, people, and tongue.” (Revelation 7:9). When we celebrate the mystery of our salvation in the sacraments we participate in this eternal liturgy.

235. How does the Church on earth celebrate the liturgy?

1140-1144
1188

The Church on earth celebrates the liturgy as a priestly people in which each one acts according to his proper function in the unity of the Holy Spirit. The baptized offer themselves in a spiritual sacrifice; the ordained ministers celebrate according to the Order they received for the service of all the members of the Church; the bishops and priests act in the Person of Christ the Head.

236. How is the liturgy celebrated?

1145

The celebration of the liturgy is interwoven with signs and symbols whose meaning is rooted in creation and in human culture. It is determined by the events of the Old Testament and is fully revealed in the Person and work of Christ.

237. From where do the sacramental signs come?

1146-1152
1189

Some come from created things (light, water, fire, bread, wine, oil); others come from social life (washing, anointing, breaking of bread). Still others come from the history of salvation in the Old Covenant (the Passover rites, the sacrifices, the laying on of hands, the consecrations). These signs, some of which are normative and unchangeable, were taken up by Christ and are made the bearers of his saving and sanctifying action.

238. What is the link between the actions and the words in the celebration of the sacraments?

1153-1155
1190 

Actions and words are very closely linked in the celebration of the sacraments. Indeed, even if the symbolic actions are already in themselves a language, it is necessary that the words of the rite accompany and give life to these actions. The liturgical words and actions are inseparable both insofar as they are meaningful signs and insofar as they bring about what they signify.

239. What are the criteria for the proper use of singing and music in liturgical celebrations?

1156-1158
1191 

Since song and music are closely connected with liturgical action they must respect the following criteria. They should conform to Catholic doctrine in their texts, drawn preferably from Sacred Scripture and liturgical sources. They should be a beautiful expression of prayer. The music should be of a high quality. Song and music should encourage the participation of the liturgical assembly. They should express the cultural richness of the People of God and the sacred and solemn character of the celebration. “He who sings, prays twice” (Saint Augustine).

240. What is the purpose of holy images?

1159-1161
1192

The image of Christ is the liturgical icon par excellence. Other images, representations of Our Lady and of the Saints, signify Christ who is glorified in them. They proclaim the same Gospel message that Sacred Scripture communicates by the word and they help to awaken and nourish the faith of believers.

When is the liturgy celebrated?

241. What is the center of the liturgical season?

1163-1167
1193

The center of the liturgical season is Sunday which is the foundation and kernel of the entire liturgical year and has its culmination in the annual celebration of Easter, the feast of feasts.

242. What is the function of the liturgical year?

1168-1173
1194-1195

In the liturgical year the Church celebrates the whole mystery of Christ from his Incarnation to his return in glory. On set days the Church venerates with special love the Blessed Virgin Mary, the Mother of God. The Church also keeps the memorials of saints who lived for Christ, who suffered with him, and who live with him in glory.

243. What is the Liturgy of the Hours?

1174-1178
1196 

The Liturgy of the Hours, which is the public and common prayer of the Church, is the prayer of Christ with his body, the Church. Through the Liturgy of the Hours the mystery of Christ, which we celebrate in the Eucharist, sanctifies and transforms the whole of each day. It is composed mainly of psalms, other biblical texts, and readings from the Fathers and spiritual masters.

Where is the liturgy celebrated?

244. Does the Church need places in order to celebrate the liturgy?

1179-1181
1197-1198

The worship “in spirit and truth” (John 4:24) of the New Covenant is not tied exclusively to any place because Christ is the true temple of God. Through him Christians and the whole Church become temples of the living God by the action of the Holy Spirit. Nonetheless, the people of God in their earthly condition need places in which the community can gather to celebrate the liturgy.

245. What are sacred buildings?

1181
1198-1199

They are the houses of God, a symbol of the Church that lives in that place as well as of the heavenly Jerusalem. Above all they are places of prayer in which the Church celebrates the Eucharist and worships Christ who is truly present in the tabernacle.

246. What are the privileged places inside sacred buildings?

1182-1186

They are: the altar, the tabernacle, the place where the sacred Chrism and other holy oils are kept, the chair of the bishop (cathedra) or the chair of the priest, the ambo, the baptismal font, and the confessional.

LITURGICAL DIVERSITY AND THE UNITY OF THE MYSTERY

247. Why is the one Mystery of Christ celebrated by the Church according to various liturgical traditions?

1200-1204
1207-1209

The answer is that the unfathomable richness of the mystery of Christ cannot be exhausted by any single liturgical tradition. From the very beginning, therefore, this richness found expression among various peoples and cultures in ways that are characterized by a wonderful diversity and complementarity.

248. What is the criterion that assures unity in the midst of plurality?

1209

It is fidelity to the Apostolic Tradition, that is, the communion in the faith and in the sacraments received from the apostles, a communion that is both signified and guaranteed by apostolic succession. The Church is Catholic and therefore can integrate into her unity all the authentic riches of cultures.

249. Is everything immutable in the liturgy?

1205-1206

In the liturgy, particularly in that of the sacraments, there are unchangeable elements because they are of divine institution. The Church is the faithful guardian of them. There are also, however, elements subject to change which the Church has the power and on occasion also the duty to adapt to the cultures of diverse peoples.
