The role of Advent
The Catholic Encyclopedia notes that the liturgical season of Advent is a time for the faithful to:
- prepare themselves worthily to celebrate the anniversary of the Lord's coming into the world as the incarnate God of love,
- thus to make their souls fitting abodes for the Redeemer coming in Holy Communion and through grace, and
- thereby to make themselves ready for His final coming as judge, at death and at the end of the world.
The Office in Advent
You can find detailed notes on how the Office operates during Advent compared to throughout the year via the following links:
- Antiphons for the psalms Part I;; Antiphons Part II;
- Canticle antiphons and collects Part I; Canticle antiphons and collects for Advent
Ribbons
The Office in Advent is quite complex, and a time when ribbons need to be deployed, no matter how familiar you might be with the Office.
My suggestion would be to place your ribbons as follows:
- to the relevant parts of the 'Ordinary of Advent', MD 9*ff;
- on the day of the week in Advent;
- as well as the relevant hour of the psalter.
Sundays in Advent are all first class, with their own proper antiphons and proper texts (chapter, hymn etc). In general, the Lauds antiphons are used for all of the hours (ie from I Vespers on Saturday until II Vespers), using the normal principles (that is, the fourth antiphon is omitted at Vespers; the first antiphon is used at Prime, the second at Terce, etc, skipping the fourth as usual). These antiphons are then used for the minor hours throughout that week (MD 13*ff puts them together to make it easier to find the right antiphon for the relevant hour).
Weekdays up to 17 December/fourth week of Advent
The ordinary days of Advent are of the third class. As usual, the collects are from the previous Sunday (with the exception of the Ember days in week three of Advent, which have their own particular collects).
A few key things to particularly take note of:
- at Lauds and Vespers: use the correct chapter, hymn, responsory etc from the Ordinary of Advent (MD9*;15*) NOT from the psalter for the day;
- at Lauds and Vespers use the Benedictus and Magnificat antiphons prescribed for the day and week;
- at the minor hours, use the antiphon set for that hour for the relevant week (MD 13*ff) and from Terce to None, the chapter and versicle for Advent (set out in the psalter).
The other key point to note is that on days when a feast is celebrated (such as the Immaculate Conception) a commemoration of Advent is always made at both Lauds and Vespers.
The Monastic Diurnal is rather unhelpful on this, as, presumably in the interests of space, it doesn't include the versicles and collect on the same pages as the relevant canticle antiphons, but the principle is to use the Benedictus or Magnficat antiphon that would otherwise have been said on that day, followed by the versicle from the relevant Advent Office, followed by the collect of the week or day), all said immediately after the collect of the feast.
From 17 December....
In the last part of of Advent the liturgy intensifies, adding a little complexity.
First, at Vespers, the beautiful 'O Antiphons' (MD 35*), one for each day, are sung with the Magnificat. These displace the Magnificat antiphon that would otherwise be said on these days (in the third week of Advent). There are numerous recordings of these wonderful pieces of chant available online, do listen.
Secondly, whereas previously Lauds and Vespers used the 'throughout the year' antiphons, there is now a set used at these hours (and the rest as per the normal rules) for the psalms for each day of the week (MD 37*ff).
Thirdly, a couple of the Benedictus antiphons are said on specific dates (see MD 41*).
In all cases, following the Ordo provided here should be of assistance!
Compline
Throughout this season, the Marian antiphon at the end of Compline is Alma Redemptoris Mater, MD 265, with the accompanying prayers that immediately follow (labelled for use up until 24 December).
