The third day within the Octave of All Saints is of semi-double rite and its liturgical colour is white. It is also the Commemoration of All the Faithful Departed - All Souls' Day in popular parlance.
At Mattins the invitatory and hymn are as on the feast. The antiphons and psalms are as were sung on the feast except that the antiphons are not doubled. In the first nocturn the lessons are for Monday of the first week of November, the second chapter of the Prophet Ezechiel with the responsories of the Octave. The first lesson begins with the first verse of the chapter rather than with the second verse as in the later editions and the text of the modern second and third lesson is combined into the second lesson of the day. The third lesson is formed from chapter three postponed to Tuesday in the later books. In the second nocturn the lessons are from a sermon of the Venerable Bede and in the third nocturn the homily on St. Matthew's gospel is from St. Augustine. The Te Deum is sung. At Lauds and the antiphons Vidi turbam magnam etc, are sung, not doubled, with psalms 99, 92, 62-66, Benedicite, 148-149-150. The antiphon on the Benedictus and collect are as on the feast.
At the end of Lauds Fidelium animae is omitted and Mattins and Lauds of the Dead are sung. Mattins begins with the invitatory Regem cui omnia vivunt, Venite adoremus. There are no Office hymns. In the first nocturn the antiphons Dirige Domine etc are sung with psalms 5, 6 & 7. Instead of Gloria Patri etc Requiem aeternam dona eis Domine and Et lux perpetua luceat eis is sung after the last verse of each psalm. After the versicle, its respond and a silent Pater noster the first lesson is begun without any absolution or blessing. The lessons for the Office all come from the Book of Job, in the first nocturn they are taken from the seventh and tenth chapters. They are the same as those found in modern editions of the Breviary up until the 1911-13 reform. The lessons are followed by the responsories Credo quod Redemptor meus vivit etc, Qui Lazarum resuscitasti etc & Domine, quando veneris judicare terram etc. In the second nocturn the antiphons In loco pascuae etc are sung with psalms 22, 24 & 26. After the versicle, its respond and a Pater noster the lessons are taken from the thirteenth and fourteenth chapters of Job. These are the same as those found in pre-1911 editions of the Breviary but new lessons were introduced for November 2nd following that reform: one casualty being the lesson, famous to readers of English from the BCP, 'Man that is born of woman hath but a short time to live...'. The responsories are Memento mei Deus etc, Hei mihi Domine etc and Ne recorderis peccata mea Domine etc. In the third nocturn the antiphons Complaceat etc are sung with psalms 39, 40 & 41. Again, after the versicle, its respond and Pater noster three lessons are sung from Job, in the third nocturn from the seventeenth, nineteenth and tenth chapters. The eighth lesson ends slightly differently to the text given in the modern books. The three responsories are Domine secundum actum etc, Libera me Domine de viis inferni etc and Libera me Domine de morte aeterna etc. Lauds immediately follow the repition of the last verse of the responsory. The antiphons Exsultaunt etc are sung with psalms 50, 64, 62-66, Ego dixi and 148-149-150. The antiphon on the Benedictus is formed of the LORD's moving words Ego sum resurrectio et vita etc. After the antiphon is repeated there follows a silent Pater noster, a series of versicles and their responds and the collect Fidelium (with the long conclusion).
At the Hours (of the Second Day with the Octave) the antiphons Vidi turbam magnum etc are sung. At Prime (Pss. 53, 118i, 118ii) the lectio brevis is Benedictio et claritas. The Dominical preces are omitted during the Octave.
In Cathedral and Collegiate Churches two High Masses are sung: one of the day within the Octave, after Terce, and a Requiem after None. In other churches only the Requiem need be celebrated. Private Masses may be of Requiem. The collect is Fidelium, the epistle from Corinthians Fratres: Ecce mysterium vobis dico, the sequence Dies irae is sung and the common preface is sung. The dismissal is Requescant in pace which is sung by the deacon facing the altar.
Vespers are of the Octave. The antiphons Vidi turbam magnum etc are sung, undoubled, with psalms 109, 110, 111, 112 & 115. The Office hymn is Christe Redemptor omnium and the antiphon on the Magnificat O quam gloriosum etc. After the collect of the Octave a commemoration is sung of SS Vitalis and Agricola. The Suffrages at Vespers and the Dominical preces at Compline are omitted during the Octave.
