"Seven times a day I praise you
because your judgments are righteous."
(Psalm 119:164)

1174 The mystery of Christ, his Incarnation and Passover, which we celebrate in the Eucharist especially at the Sunday assembly, permeates and transfigures the time of each day, through the celebration of the Liturgy of the Hours, "the divine office."  This celebration, faithful to the apostolic exhortations to "pray constantly," is "so devised that the whole course of the day and night is made holy by the praise of God." In this "public prayer of the Church," the faithful (clergy, religious, and lay people) exercise the royal priesthood of the baptized. Celebrated in "the form approved" by the Church, the Liturgy of the Hours "is truly the voice of the Bride herself addressed to her Bridegroom. It is the very prayer which Christ himself together with his Body addresses to the Father.

1175 The Liturgy of the Hours is intended to become the prayer of the whole People of God. In it Christ himself "continues his priestly work through his Church." His members participate according to their own place in the Church and the circumstances of their lives".  Pastors of souls should see to it that the principal hours, especially Vespers, are celebrated in common in church on Sundays and on the more solemn feasts. The laity, too, are encouraged to recite the divine office, either with the priests, or among themselves, or even individually."
