Sunday within the Octave of the Nativity
Sunday within the Octave of the Nativity is of semi-double rite and its liturgical colour is white.
At Mattins the invitatory and hymn, antiphons (not doubled) and psalms are those that were sung on the feast of the Nativity. In the first nocturn the lessons are from the Epistle to the Romans. In the second nocturn the lessons are from St. Leo on the Nativity. In the third nocturn the homily is taken from St. Ambrose on the second chapter of St. Luke's Gospel. The Te Deum is sung. At Lauds the antiphons from the Nativity, Quem vidistis etc., are sung (not doubled) with psalms 92, 99, 62, Benedicite and 148. The chapter and antiphon on the Benedictus are proper to the Sunday as is the collect. The Office hymn is A solis ortus cardine. After the collect of the Sunday a commemoration is sung of the Octave of the Nativity.
At the Hours the antiphons from Lauds are sung with the festal psalms. The hymns of the Hours are sung with the Doxology of the Incarnation. At Prime (Pss. 53, 118i, & 118ii) the lectio brevis is proper to the Sunday, Itaque jam non est servus.
Mass is sung after Terce. The Mass formulary isDum mediumetc. The Gloria is sung, the second collect is of the Octave of the Nativity. The Credo is sung and the preface and communicantes are of the Nativity.
Vespers of the Nativity are sung as on previous days, with the antiphons not doubled. From the chapter the Office is of the Sunday, the Office hymn is Jesu, Redemptor omnium. After the collect of the Sunday commemorations are sung of the following feast of St. Sylvester and of the Octave of the Nativity.
In the 'liturgical books of 1962' today is the sixth day within the Octave of the Nativity. Mattins has the psalmody of the Nativity (with the curtailed Ps. 88 ) and the usual cut-down single nocturn of three lessons. At the Hours the antiphons and psalmody are of from the ferial Psalter. There is no proper Doxology at the hymns of the Hours. Mass has but a single collect. Vespers are of the Nativity without any commemorations.
