The Morning Office on Sunday shall begin with Psalm 66 recited straight through without an antiphon. After that let Psalm 50 be said with “Alleluia,” then Psalms 117 and 62, the Canticle of Blessing and the Psalms of praise; then a lesson from the Apocalypse to be recited by heart, the responsory, the Ambrosian hymn, the verse, the canticle from the Gospel book, the litany and so the end.
CHAPTER 13
How the Morning Office Is to Be Said on Weekdays
Feb. 15—June 16—Oct. 16
On weekdays the Morning Office shall be celebrated as follows. Let Psalm 66 be said without an antiphon and somewhat slowly, as on Sunday, in order that all may be in time for Psalm 50, which is to be said with an antiphon. After that let two other Psalms be said according to custom, namely: on Monday Psalms 5 and 35, on Tuesday Psalms 42 and 56, on Wednesday Psalms 63 and 64, on Thursday Psalms 87 and 89, on Friday Psalms 75 and 91, and on Saturday Psalm 142 and the canticle from Deuteronomy, which is to be divided into two sections each terminated by a “Glory be to the Father.” But on the other days let there be a canticle from the Prophets, each on its own day as chanted by the Roman Church. Next follow the Psalms of praise, then a lesson of the Apostle to be recited from memory, the responsory, the Ambrosian hymn, the verse, the canticle from the Gospel book, the litany, and so the end.
Feb. 16—June 17—Oct. 17
The Morning and Evening Offices should never be allowed to pass without the Superior saying the Lord’s Prayer in its place at the end so that all may hear it, on account of the thorns of scandal which are apt to spring up. Thus those who hear it, being warned by the covenant which they make in that prayer when they say, “Forgive us as we forgive,” may cleanse themselves of faults against that covenant.
But at the other Offices let the last part only of that prayer be said aloud, so that all may answer, “But deliver us from evil.”

How the Night Office Is to Be Said on the Feasts of the Saints
Feb. 17—June 18—Oct. 18
On the feasts of Saints and on all festivals let the Office be performed as we have prescribed for Sundays, except that the Psalms, the antiphons and the lessons belonging to that particular day are to be said. Their number, however, shall remain as we have specified above.
