At Mattins there are the usual three nocturns. The invitatory and hymn are as sung on previous 'green' Sundays. In the first nocturn the lessons are the Incipit of the book of Judith. In the second nocturn the lessons are from St. Ambrose on Elias and fasting. In the third nocturn the lessons are a homily from St. Augustine on St. Lukes's Gospel. At Lauds, after the collect of the Sunday, the Suffrage of the Saints is sung.
At Prime (Pss. 117, 118i & 118ii) Quicumque is 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 Creed is sung and the preface is of the Holy Trinity.
Vespers are of the Sunday. After the collect of the Sunday a commemoration is sung of the following feast of SS Cyprian and Justina followd by the Suffrage of the Saints. At Compline the Dominical preces are sung.
In the 'liturgical books of 1962' Mattins is cut down to one nocturn of three lessons. At Lauds the Suffrage is not sung. At Prime both Quicumque and the preces are always omitted on 'green' Sundays. At Mass there is only one collect. At Vespers there are no commemorations or Suffrage. At Compline no preces.
