Constitution

1. With due regard for the demands of the apostolate, the liturgy of the hours should be so arranged in each community that the different times of the day will be truly sanctified.
2. The daily office revolves round two pivotal moments: Lauds as morning prayer and Vespers as evening prayer. These are to be regarded as the principal hours and celebrated as such.

1. In our communities, the conventual Mass and the liturgy of the hours should be celebrated daily in choir.
2. Where the conventual Mass and the entire office cannot be celebrated in common, due to a legitimate impediment, at least Lauds and Vespers should be celebrated. If the situation is habitual it should be acknowledged by the prior provincial and his council.
3. When the divine office cannot be celebrated in choir for a just reason, according to the judgment of the major superior, it should be celebrated in another suitable sacred place.

The brothers should avail of sacramental confession frequently so as to foster the process of on-going conversion of life.

1. The celebration of the conventual Mass ought to be the centre of the community liturgy. The memorial of the Lord’s death and resurrection is the bond of brotherly love, and the principal source of apostolic vigour.
2. For this reason it is preferable that the conventual Mass be concelebrated because in it the unity of the sacerdotal ministry and of the community is more clearly signified.
3. The daily celebration of the eucharistic sacrifice is recommended for all priests because even in the absence of the faithful it is an act of Christ and of the Church.
4. Those who are not priests should participate in Mass daily.

The brothers should celebrate publicly the conventual Mass and the liturgy of the hours. And since the liturgy is an act of the whole people of God, the participation of the people in all our celebrations should be promoted.

It is the express wish of St Dominic that the solemn celebration of the liturgy in common be accepted as one of the principal duties of our vocation.
The mystery of salvation is present and active in the liturgy, especially in the Eucharist. The brothers should take part in the mystery, contemplate it, proclaim it through preaching to all so that they may be incorporated into Christ through the sacraments of faith.
In the liturgy, the brothers, together with Christ, glorify God for his eternal plan and for the wonderful workings of grace. They pray to the Father of mercies for the whole Church, for
the needs and salvation of the whole world. Thus, the celebration of the liturgy is the centre and heart of our life, the basic source of our unity.

Superiors, moderators of centres for institutional studies and masters of the brothers in formation administer correction to promote regular observance and the salutary improvement of the brothers..

1. Religious consecration and the apostolic calling impel the brothers more than the rest of the faithful to practice self-denial. By taking up their cross and carrying in their own body and soul the sufferings of Jesus, they earn the glory of the resurrection for themselves and for others.
2. Imitating Saint Dominic who, ‘when he was living with us in the flesh, walked by the Spirit, not only not fulfilling the desires of the flesh, but actually quenching them at the source,’1 the brothers should practice the virtue of penance especially by observing faithfully all that belongs to our life.

The habit of the Order comprises a white tunic, scapular and capuce, together with a black cappa and capuce, a leather belt and a rosary. (see Appendix n. 3).

1. Silence is to be carefully observed by the broth­ers especially in places and at times devoted to prayer and study. Silence is the guardian of all observance and contributes greatly to the interior quality of religious life, to peace, prayer, the study of truth and authenticity in preaching. 
2. Silence is to be tempered by charity so that it never impedes fruitful communication.
