CHAPTER 15
At What Times “Alleluia” Is to Be Said
Feb. 18—June 19—Oct. 19
From holy Easter until Pentecost without interruption let “Alleluia” be said both in the Psalms and in the responsories. From Pentecost to the beginning of Lent let it be said every night with the last six Psalms of the Night Office only. On every Sunday, however, outside of Lent, the canticles, the Morning Office, Prime, Terce, Sext and None shall be said with “Alleluia,” but Vespers with antiphons.
The responsories are never to be said with “Alleluia” except from Easter to Pentecost.
CHAPTER 16
How the Work of God Is to Be Performed During the Day
Feb. 19—June 20—Oct. 20
“Seven times in the day,” says the Prophet, “I have rendered praise to You.” Now that sacred number of seven will be fulfilled by us if we perform the Offices of our service at the time of the Morning Office, of Prime, of Terce, of Sext, of None, of Vespers and of Compline, since it was of these day Hours that he said, “Seven times in the day I have rendered praise to You.” For as to the Night Office the same Prophet says, “In the middle of the night I arose to glorify You.”
Let us therefore bring our tribute of praise to our Creator “for the judgments of His justice” at these times: the Morning Office, Prime, Terce, Sext, None, Vespers and Compline; and in the night let us arise to glorify Him.
