September 29th - Dedication of St. Michael the Archangel

The feast of the Dedication of St. Michael the Archangel is of double rite and its liturgical colour is white. The eighteenth Sunday after Pentecost (this year the first Sunday of October) is commemorated at Vespers, Mattins, Lauds and Mass.

At first Vespers yesterday afternoon the antiphons Stetit angelus etc were sung, doubled, with psalms 109, 110, 111, 112 & 116. The Office hymn was Tibi Christe splendor Patris. After the collect of the feast a commemoration was sung of the Sunday (the antiphon on the Magnificat being Adaperiat Dominus etc for the Saturday before the first Sunday of October). The Suffrages were omitted as were the Dominical preces at Compline.

At Mattins the invitatory is Regem Archangelum Dominium, Venite adoremus and the Office hymn is, again, Tibi Christe splendor Patris. In the first nocturn the antiphons Concussum est mare etc are sung with psalms 8, 10 & 14. The lessons are taken from the prophet Daniel. These are the same as those found in the later editions of the BR. In the second nocturn the antiphons Michael Archangele etc are sung with psalms 18, 23 & 33. The lessons in the second nocturn are taken from a homily of St. Gregory the Great. Again, these are the same as those found in the later books. In the third nocturn the antiphons Angelus Archangelus Michael etc are sung with psalms 95, 96 & 102. The lessons are a homily of St. Jerome on St. Matthew's Gospel. These are longer than those found in the post-Clementine editions. The eighth and ninth lessons are read together to form the eighth lesson of the day and the ninth lesson is formed of the three lessons for the homily of the Sunday. These are from a homily of St. Peter Chrysologus on St. Matthew's Gospel. The lessons are longer than those found in the post-Clementine editions with the seventh lesson (of the Sunday) consisting of both the modern seventh and eighth lessons. The eighth lesson consists of all of the modern ninth lesson and additional texts. The text of the ninth lesson is not found in the modern books. The Te Deum is sung.

At Lauds the antiphons Stetit angelus etc are sung with Pss. 92, 99, 62-66, Benedicite & 148-149-150. The Office hymn is Christe, sanctorum decus Angelorum. After the collect of the feast a commemoration of the Sunday is sung. The Suffrages are omitted.

Mass is sung after Terce. The Gloria is sung, the second collect is of the Sunday. The Creed is sung, the common preface is sung and the last Gospel is of the Sunday.

After the collect of the feast commemorations are sung of the following feast of St. Jerome and then of the Sunday.
