The ninth Sunday after Pentecost is of semi-double rite. This year it is also the third Sunday of August and the Sunday within the Octave of St. Lawrence. The liturgical colour is red.
At Vespers yesterday afternoon the antiphons Laurentius ingressus est etc., not doubled, were sung with psalms 109, 110, 111, 112 & 115. From the chapter, O Altitudo, the Office was of the Sunday and the Office hymn O lux beata Trinitas. The antiphon on the Magnificat was Omnis sapientia for the Saturday before the third Sunday of August. After the collect of the Sunday commemorations were sung of the preceding Office of the Octave of St. Lawrence and of St. Clare. The Suffrages were omitted due to the Octave as were the Dominical preces at Compline.
At Mattins the invitatory is Adoremus Dominum and the Office hymn Nocte surgentes. In the first nocturn (Pss. 1, 2, 3, 6, 7, 8, 9, 10, 11, 12, 13 & 14) are sung. The lessons are the Incipit of the Book of Wisdom. The first lesson is longer than the form given in the modern editions. It continues Spiritus enim ... superveniente iniquitate. The second lesson begins Benignus est enim and continues until quod mentitur occidit animam - what is now the end of third lesson. The text of the third lesson is not found in the modern editions Nolite zelare ...qui sunt ex parte illius, vv. 12-16. In the second nocturn (Pss. 15, 16 & 17) the lessons are from St. Ambrose. Lessons IV and V are substantially longer than those in the modern books with additional text not appearing in the modern editions, lesson VI is longer by a sentence. In the third nocturn (Pss. 18, 19 & 20) the homily is from St. Gregory on St. Luke's Gospel. Again the version in the Tridentine Breviary is considerably longer than that found in the post-Clementine editions. The Te Deum is sung.
At Lauds the Sunday psalms (Pss. 92, 99, 62-66, Benedicite & 148-49-150) are sung. After the collect of the Sunday commemorations are sung of the Octave of St. Lawrence and of St. Clare. The Suffrages are omitted.
At Prime (Pss. 53, 117, 118i & 118ii) Quicumque is sung but the Dominical preces are omitted being within an Octave.
Mass is sung after Terce. The Gloria is sung, the second collect is of the Octave of St. Lawrence, the third collect is of St. Clare. The Credo is sung, the Common Preface is sung.
Vespers are of the Sunday (Pss. 109, 110, 111, 112 & 113). The Office hymn is Lucis creator. After the collect of the Sunday commemorations are sung of the following day within the Octave of St. Lawrence and of SS Hippolytus and Cassian. The Suffrages are omitted as are the Dominical preces at Compline being within an Octave.
