Ember Friday in the Octave of Pentecost

Ember Friday in the Octave of Pentecost is the second of the summer Quarter-Tense days. It is of semi-double rite. The liturgical colour is the red of the Octave.

The Office is as on the feast of Pentecost, except for those parts that are proper, but the antiphons at Mattins, Lauds and Vespers are not doubled. At Mattins the invitatory, hymn, antiphons and psalms are those that were sung on the feast. The versicle and response are Spiritus Paraclitus, alleluia and Docebit vos omnia, alleluia. The lessons of the homily are taken from the writings of St. Ambrose on St. Luke's Gospel. At Lauds the antiphon on the Benedictus and collect are proper to the day.

At the Hours all is celebrated as on Pentecost Sunday. At Terce the hymn is Veni Creator. The Pentecost Doxology is sung at the conclusion of the hymns.

Mass, as on Wednesday, is sung after None. This is common to the Ember Days of the other seasons. Unlike the other Ember Days the deacon and subdeacon do not wear folded chasubles as the colour of the Octave is used. The Mass is proper with the introit Repleatur os meum etc. The Gloria is sung, the second collect is Ecclesiae, for the Church. The sequence Veni Sancte Spiritus is sung, the Creed is sung, the preface, Hanc igitur and communicantes are of Pentecost.

Vespers are as on the feast, except the antiphons are not doubled. The antiphon on the Magnificat and collect are proper. Commemorations are sung of St. Ephrem the Syrian and SS Mark and Marcellianus.
