What kind of pronunciation is to be attended to in the recitation of the Divine Office? The pronunciation should be vocal--that is, there should be some sound, _aliquis sonitus verborum_, as St. Alphonsus writes (n. 162). Hence, to read the Breviary merely mentally or with the eyes only, does not satisfy the obligation.[A] Although the reader may not hear the sound produced, he must be careful to form with his lips every syllable. This must be done, not necessarily in a throaty way. The formation of the words clearly with the lips suffices. But writers on this point emphasise the importance of audible recitation as a preventive of slurred, mutilated Latinity, which often leads to careless, or even invalid recitation. They note, too, that the reading with the eye merely, is a habit which readers bring from the reading of other books to their reading of the Breviary. German authors dwell at length on the fact that many priests, very early in their career, contract the habit of faulty vocalisation of liturgy, and that they never seem to notice their fault, or at least never seem to attempt an amendment. These authors attribute the defect to sub-voce recitation and recommend audible recitation, long and frequent audible recitation, to all priests reading their hours. [Footnote A: The privilege of mental recitation was granted to the Friar Minor by Pope Leo X. and Pius V., but it is probable that the privilege was withdrawn by Pope Gregory XV. in 1622, in his letter _Romanus Pontifex_; and Urban VIII., 1635, withdrew all privileges granted _vivae vocis oraculo_. The text of the document granting the privilege is obscurely worded. Still, several theologians of repute maintain that the privilege still exists and extends to the whole office. This is taught by the Salaraenticenses, _De hor. can. cap._ 3, n. 55; Tamburini, Rodriguez, etc., others opposed this view of the privilege existing after Pope Urban's letter _Alias_. This privilege extends to secular priests who are Franciscan tertiaries, if it exists at all.] Can a priest fulfil his obligation by reciting the office with a companion? Yes, he can, for such recitation is the Church's ideal; and the priest who says his part (alternate verses, etc.), as in choir, fulfils his obligation, even when his companion is a layman or an inattentive person. In such recitation a priest should be careful (1) that his recitation be of alternate verses, (2) that the verse recitation be successive and not simultaneous, (3) that the verses, etc., chanted by one companion (or by one choir) be heard by the other companion or choir. There is no necessity for a priest at such recitation to say one verse in a loud voice and to say his companion's verses in a low, inaudible voice. Some priests do this with distressing results. Imperfect vocal recitation often leads to doubts and scruples in old age when remedies either cannot be applied or prove useless.
