Tomorrow is the XX Sunday after Pentecost and the first Sunday of October.
Our profound apologies to Ordo customers for the 'typo' repeating XIX instead of XX. The Sunday Office is classically that of a semi-double 'green' Sunday.
At Vespers on Saturday the ferial psalms are sung and the antiphon at the Magnificat is Adaperiat Dominus (for the Saturday before the 1st Sunday of October). A commemoration is made of the preceding Office of SS Cosmas and Damian and of St. Wenceslaus (of Christmas Carol fame). The Suffrage of the Saints is also sung. At Compline the Dominical preces are sung.
At Mattins the invitatory is Adoremus... and the hymn Primo die... Mattins has three nocturns and the beginning of the first Book of Machabees is read in the first nocturn. At Lauds the hymn is Aeterne rerum. This invitatory and the hymns at Mattins and Lauds are sung on Sundays now until the last Sunday in November. At Lauds a commemoration of St. Wenceslaus is made and the Suffrage of the Saints is sung.
At Prime the Athanasian Creed, Quicumque, is sung as are the Dominical preces. At Mass the Gloria is sung, the second collect is of St. Wenceslaus and the third collect A cunctis. The Credo is sung and the preface is that of the Holy Trinity as used on Sundays.
Vespers are first Vespers of the Feast of the Dedication of St. Michael the Archangel with a commemoration of the Sunday. At Compline the solemn tone for Te lucis is used.
Users of the 1962 books will have been celebrating their delayed Ember Saturday. At Vespers they will use the antiphon at the Magnificat Adonai (for the Saturday before the 4th Sunday of September.) The different antiphons of course dictate different tones for the Canticle. Whilst the Old Rite will use Tone 8G for the Magnificat the 1962 will use 3g (we will consider musical changes in a series of separate posts later). No commemorations will be made at Vespers and the Suffrage of the Saints has been abolished.
At Mattins, with only one nocturn, the invitatory and hymn will be different and the Book of Judith read. At Lauds the hymn will be different and there will be no commemortion or Suffrage.
At Prime the Athanasian Creed is not sung and there are no preces. At Mass there is only one collect and St. Wenceslaus is entirely omitted this year. Vespers will actually be the same!
