III. The Reform of the Sacred Liturgy

In this restoration, both texts and rites should be drawn up so that they express more clearly the holy things which they signify; the Christian people, so far as possible, should be enabled to understand them with ease and to take part in them fully, actively, and as befits a community.

Wherefore the sacred Council establishes the following general norms:

A) General norms

2. In virtue of power conceded by the law, the regulation of the liturgy within certain defined limits belongs also to various kinds of competent territorial bodies of bishops legitimately established.

3. Therefore no other person, even if he be a priest, may add, remove, or change anything in the liturgy on his own authority.

As far as possible, notable differences between the rites used in adjacent regions must be carefully avoided.

B) Norms drawn from the hierarchic and communal nature of the Liturgy

This applies with especial force to the celebration of Mass and the administration of the sacraments, even though every Mass has of itself a public and social nature.

Consequently they must all be deeply imbued with the spirit of the liturgy, each in his own measure, and they must be trained to perform their functions in a correct and orderly manner.

C) Norms based upon the didactic and pastoral nature of the Liturgy

1) In sacred celebrations there is to be more reading from holy scripture, and it is to be more varied and suitable.

2) Because the sermon is part of the liturgical service, the best place for it is to be indicated even in the rubrics, as far as the nature of the rite will allow; the ministry of preaching is to be fulfilled with exactitude and fidelity. The sermon, moreover, should draw its content mainly from scriptural and liturgical sources, and its character should be that of a proclamation of God's wonderful works in the history of salvation, the mystery of Christ, ever made present and active within us, especially in the celebration of the liturgy.

3) Instruction which is more explicitly liturgical should also be given in a variety of ways; if necessary, short directives to be spoken by the priest or proper minister should be provided within the rites themselves. But they should occur only at the more suitable moments, and be in prescribed or similar words.

4) Bible services should be encouraged, especially on the vigils of the more solemn feasts, on some weekdays in Advent and Lent, and on Sundays and feast days. They are particularly to be commended in places where no priest is available; when this is so, a deacon or some other person authorized by the bishop should preside over the celebration.

2. But since the use of the mother tongue, whether in the Mass, the administration of the sacraments, or other parts of the liturgy, frequently may be of great advantage to the people, the limits of its employment may be extended. This will apply in the first place to the readings and directives, and to some of the prayers and chants, according to the regulations on this matter to be laid down separately in subsequent chapters.

3. These norms being observed, it is for the competent territorial ecclesiastical authority mentioned in Art. 22, 2, to decide whether, and to what extent, the vernacular language is to be used; their decrees are to be approved, that is, confirmed, by the Apostolic See. And, whenever it seems to be called for, this authority is to consult with bishops of neighboring regions which have the same language.

4. Translations from the Latin text into the mother tongue intended for use in the liturgy must be approved by the competent territorial ecclesiastical authority mentioned above.

D) Norms for adapting the Liturgy to the culture and traditions of peoples

1) The competent territorial ecclesiastical authority mentioned in Art. 22, 2, must, in this matter, carefully and prudently consider which elements from the traditions and culture of individual peoples might appropriately be admitted into divine worship. Adaptations which are judged to be useful or necessary should when be submitted to the Apostolic See, by whose consent they may be introduced.

2) To ensure that adaptations may be made with all the circumspection which they demand, the Apostolic See will grant power to this same territorial ecclesiastical authority to permit and to direct, as the case requires, the necessary preliminary experiments over a determined period of time among certain groups suited for the purpose.

3) Because liturgical laws often involve special difficulties with respect to adaptation, particularly in mission lands, men who are experts in these matters must be employed to formulate them.

E) Promotion of Liturgical Life in Diocese and Parish

And therefore the liturgical life of the parish and its relationship to the bishop must be fostered theoretically and practically among the faithful and clergy; efforts also must be made to encourage a sense of community within the parish, above all in the common celebration of the Sunday Mass.

F) The Promotion of Pastoral-Liturgical Action

So that this pastoral-liturgical action may become even more vigorous in the Church, the sacred Council decrees:

Sometimes it may be expedient that several dioceses should form between them one single commission which will be able to promote the liturgy by common consultation.

These three commissions must work in closest collaboration; indeed it will often be best to fuse the three of them into one single commission.
