August 6th - The Transfiguration of the LORD

The feast of the Transfiguration of the LORD is a feast of double rank.

At Vespers yesterday afternoon the proper antiphons Assumpsit Jesus Petrum et Jacobum etc were sung with the Psalms for first Vesper from the Commmon of Apostles (109, 110, 111, 112 & 116). The Office hymn was Quicumque Christum quaeritis. The antiphon on the Magnificat was Christus Jesus, splendor Patris etc. The collect was proper. A commemoration was sung of the precdding Office of the Dedication of Sancta Maria ad Nives, followed by a commemoration of SS Xystus, Felicissimus and Agapitus. Because of the double feast the Suffrages were omitted at Vespers and, at Compline, the Dominical preces were omitted for the same reason. At Compline, and at all the Hours the hymns have the Doxology Gloria tibi Domine, Qui apparusti hodie, Cum Patre et almo Spiritu, In sempiterna saecula.

At Mattins the invitatory is Summum Regem gloriae, Venite adoremus. The Office hymn is as at Vespers. In the first nocturn the antiphons are proper, Paulo minus etc, are sung with psalms 8, 28 & 44. The lessons in the first nocturn are from the Second Epistle of St. Peter. These are identical to those found in modern editions. In the second nocturn the antiphons Illuminans etc are sung with psalms 75, 83, and 86. The lessons are from a sermon of St. Leo. Again, these are identical to those found in modern edtions of the Breviary. In the third nocturn the antiphons Thabor et Hermon etc are sung with psalms 88, 96 and 103. The homily in the third nocturn is taken from St. Chrysostom's 57th homily on St. Matthew's Gospel. The eighth lesson is shorter in the Tridentine Breviary ending with ... a melioribus confirmari. The ninth lesson is for SS Xystus etc. The Te Deum is sung.
