Diocese of Westminster Ordo 2026 LITURGICAL CALENDAR 2025-2026 The new edition of the ‘Lectionary for Mass’ (‘Ordo Lectionum Missae’) confirmed by the Apostolic See in 2023 came into use in England and Wales on the First Sunday of Advent 2024. By decree of the Bishops’ Conference, ‘from that date forward, no other English language edition of the ‘Lectionary for Mass’ may be used in the dioceses of England and Wales.’ THE SEASON OF ADVENT Advent has a twofold character:
it is a time of preparation for the Solemnities of Christmas, in which the First Coming of the Son of God to humanity is remembered, and likewise a time when, by remembrance of this, minds and hearts are led to look forward to Christ’s Second Coming at the end of time. For these two reasons, Advent is a time of devout and expectant delight (LY39). The playing of the organ and other musical instruments, and the decoration of the altar with flowers should be marked by a moderation suited to the character of this time of year, without expressing in anticipation the full joy of the Nativity of the Lord (GIRM 305, 313; CB 236).
The same moderation should be observed in the celebration of Matrimony (OM 32). Advent from the beginning until 16 December On weekdays of Advent on which an Optional Memorial is observed, it is possible to choose either the Office and Mass of the weekday or the Office and Mass of the Saint who is inscribed for that day in the calendar or the Martyrology (IH 244, IM 316b) . Only when some genuine need or pastoral advantage requires it may an appropriate Mass for Various Needs and Occasions or a Votive Mass be celebrated (GIRM 333). Daily Masses for the Dead are not allowed (GIRM 337) .
In the weekday Office, the invitatory antiphon, the hymns for the Office of Readings, for Lauds and for Vespers, and the antiphon for the Middle Hour are taken from those prescribed for Advent Preface of Advent I is used daily until 16 December unless other provision made. Eucharistic Prayer IV is not used in this season.
