The sixth Sunday after Pentecost is of semi-double rite. The liturgical colour, from Mattins onwards, is green.
Vespers yesterday afternoon were second Vespers of the Octave Day of SS Peter and Paul. The liturgical colour was red. The antiphons Juravit Dominus etc were sung with psalms 109, 112, 115, 125 & 138. The Office hymn was Aurea luce et decore roseo. After the collect of the Octave Day a commemoration was sung of the Sunday. The Suffrages were omitted as were the Dominical preces at Compline.
At Mattins the liturgical colour changes to green. 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 and the lessons are a continuation of the Second Book of the Kings. The lessons are the same as in the post-Clementine editions of the Breviary. In the second nocturn (Pss. 15, 16 & 17) the lessons are from St. Ambrose's Defence of David. These, again, are the same as found in the modern editions. In the third nocturn (Pss. 18, 19 & 20) the homily is from St. Ambrose on St. Mark's Gospel. The seventh lesson includes the first sentence (Consequens igitur... a jejunio liberaret) from the modern eighth lesson. In the Tridentine Breviary the eighth lesson thus begins Itaque nemo and continues with most of the modern ninth lesson until ...sed nec adhuc quidem potestis. The ninth lesson begins In modum lactis but most of its text is not found in the later books. 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 the Suffrages of the BVM Santa Maria succurre etc, the Apostles Gloriosi principes etc, of the Patron and lastly for peace Da pacem Domine etc are sung.
At Prime Pss. 53, 117, 118i & 118ii and Quicumque are sung as are the Dominical preces.
Mass is sung after Terce. The Gloria is sung, the second collect is A cunctis, the third collect is chosen by the Dean or Rector. The Credo is sung, the Common Preface is sung.
Vespers are of the Sunday, with psalms (109, 110, 111, 112 & 113). After the collect of the Sunday the Suffrages of the BVM Sancta Maria succurre etc, the Apostles Petrus Apostolus etc, of the Patron and lastly for peace Da pacem Domine are sung. At Compline the Dominical preces are sung.
