Chapter IV. Divine Office
I. CELEBRATION OF DIVINE OFFICE BY THOSE BOUND TO CHOIR
78. Until reform of the divine office is completed:
a. Communities of canons, monks, nuns, other regulars or religious bound to choir by law or constitutions must, in addition to the conventual Mass, celebrate the entire divine office daily in choir.
Individual members of these communities who are in major orders or solemnly professed, except for lay brothers, are obliged, even if lawfully dispensed from choir, to private recitation each day of the hours they do not celebrate in choir.
b. Cathedral and collegiate chapters must, besides the conventual Mass, celebrate in choir those parts of the office imposed on them by common or particular law.
Individual chapter members, besides the canonical hours obligatory for all clerics in major orders (see SC art. 96 and 89), must recite in private the hours that are celebrated by their chapter.
c. In mission regions, while preserving the religious or capitular choral discipline established by law, religious or capitulars who are lawfully absent from choir by reason of pastoral ministry may, with permission of the local Ordinary (not of his vicar general or delegate), use the concession granted by the Motu Proprio Sacram Liturgiam no. VI.
II. FACULTY OF DISPENSING FROM OR COMMUTING DIVINE OFFICE (SC ART. 97)
79. The faculty given all Ordinaries to dispense their subjects, in individual cases and for a just reason, from the obligation of the divine office in whole or in part or
to commute it is also extended to major superiors of nonexempt clerical, religious institutes and of societies of common life.
III. LITTLE OFFICES (SC ART. 98)
80. No little office can be classified as conformed to the divine office if it does not consist of psalms, readings, hymns, and prayers or if it has no relationship to the hours of the day and the particular liturgical season.
81. But little offices already lawfully approved suffice for the time being as a sharing in the public prayer of the Church, provided their make?up meets the criteria just stated.
For use as part of the public prayer of the Church, any new little office must have the approval of the Holy See.
82. The translation of the text of a little office into the vernacular for use as the public prayer of the Church must have the approval of the competent, territoral ecclesiastical authority, following approval, that is, confirmation, by the Holy See.
83. The Ordinary or major superior of the subject is the authority competent to grant use of the vernacular in the recitation of a little office to anyone bound to it by constitution or to dispense from or commute the obligation.
IV. DIVINE OFFICE OR LITTLE OFFICE CELEBRATED IN COMMON BY RELIGIOUS INSTITUTES (SC ART. 99)
84. The obligation of celebrating in common all or part of the divine office or a little office imposed by their constitution on members of institutes of perfection does not take away the faculty of omitting prime and of choosing from among the little hours the one best suited to the time of day (see Motu Proprio Sacram Liturgiam no. VI).
V. LANGUAGE FOR RECITATION OF DIVINE OFFICE (SC ART. 101)
85. In reciting the divine office in choir clerics are bound to retain the Latin language.
86. The faculty granted the Ordinary to allow use of the vernacular in individual cases by those clerics for whom the use of Latin constitutes a serious hindrance to fulfilling the obligation of the office is extended also to the major superiors of nonexempt, clerical religious institutes and of societies of common life.
87. The serious hindrance required for the concession of the faculty mentioned ought to be evaluated on the basis of the physical, moral, intellectual, and spiritual condition of the petitioner. Nevertheless, this faculty, conceded solely to make the recitation of the divine office easier and more devout, is not intended to lessen in any way the obligation of priests in the Latin rite to learn Latin.
88. The respective Ordinaries of the same language are to prepare and approve the translations of the divine office for the non-Roman rites. (For parts of the office shared with the Roman Rite, however, they are to use the version approved by competent territorial authority.) The Ordinaries are then to submit the translation for the Holy See's confirmation.
89. Breviaries for clerics who, according to the provisions of art. 101, § 2, have the right to use the vernacular for the divine office should contain the Latin text along with the vernacular.
