Sunday within the Octave of Corpus Christi

The Sunday within the Octave of Corpus Christi and the Second Sunday after Pentecost is of semi-double rite and its liturgical colour is white.

At Vespers yesterday afternoon the antiphons and psalms of the feast of Corpus Christi, Sacerdos in aeternum etc, were sung, not doubled, with psalms 109, 110, 115, 127 & 147. The chapter was of the Sunday, the hymn and the following versicle & response were of the feast. The antiphon on the Magnificat and collect were of the Sunday. After the collect of the Sunday a commemoration of the Octave was sung. The Suffrage was omitted being within an Octave.  At Compline Te lucis was sung with the melody and Doxology of the Incarnation, Jesu tibi sit gloria, Qui natus es de Virgine, Cum Patre et almo Spiritu, In sempiterna saecula. The Dominical preces were omitted.

At Mattins the invitatory is Christum Regem adoremus dominantem Gentibus: Qui se manducantibus dat spiritus pinguedinem. The Office hymn is Sacris solemnis. The antiphons and psalms are as on the feast of Corpus Christi but the antiphons are not doubled.  The lessons are proper to the Sunday. In the first nocturn these are taken from the First Book of Kings. In the second nocturn they are taken from a sermon of St. Chrysostom to the people of Antioch and the homily in the third nocturn is from St. Gregory on St. Luke's Gospel. The Te Deum is sung. At Lauds the antiphons are those sung on the feast of Corpus Christi, Sapientia etc. The chapter is of the Sunday, the hymn as on the feast. The antiphon on the Benedictus and collect are of the Sunday. After the collect of the Sunday commemorations are sung of the Octave, of St. Ephraem and of SS Mark and Marcellianus. The Suffrage is omitted.

At the Little Hours the hymns are sung to the same tone as on the feast of the Nativity of the LORD (there of course being a deep link between the Incarnation and Corpus Christi) with the Doxology Jesu tibi sit gloria etc. At Prime the festal psalms are sung (Pss. 53, 118i & 118ii), the versicle in the short responsory is Qui natus es for the feast and Octave, the short lesson is Filioli mei, of the Sunday.

Mass is sung after Terce. The Gloria is sung, the second collect is of the Octave. The Creed is sung and the preface is that of the Nativity.

In Collegiate and Cathedral Churches a Mass of the feast of Corpus Christi is sung after None with Gloria, second collect of the Sunday, the Sequence Lauda Sion, Creed, preface of the Nativity and last Gospel of the Sunday. After this a Procession is made as on the feast. Likewise in those countries where the External Solemnity of Corpus Christi is observed on the Sunday following the feast Masses are of the feast with a commemoration of the Sunday. Indeed for a few years in the second decade of the twentieth century Corpus Christi was, rather bizarrely, universally moved to the Sunday after Trinity by a motu proprio of Pius X, De Diebus festis (AAS 3, 1911, pp.305-306).

(Second section of the motu proprio: Note also the moving to Sundays of St. Joseph's March feast and the feast of the Nativity of St. John the Baptist)

At Vespers the antiphons and psalms are as at Second Vespers of the feast except that the antiphons are not doubled. The chapter is of the Sunday, the hymn, versicle & response of the feast and the antiphon on the Magnificat and collect of the Sunday. After the collect of the Sunday commemorations are sung of the Octave of Corpus Christi and of St. Francis Caracciolo.

In the 'liturgical books of 1962' Sunday within the Octave of Corpus Christi, and the Octave itself, have been abolished. The Second Sunday after Pentecost is celebrated as a 'green' Sunday. Mattins is stripped down to a single of three lessons with the invitatory and antiphons of the Sunday. There are no commemorations at either Vespers, Lauds or Mass. The hymn tones are not those of the Nativity, the Doxology has gone, the versicle at Prime is Qui sedes.
