|Our Lady of Puerto Rico, Cathedrdal San Juan Bautista|
Think of it as your final, "Goodnight, Mom! You're the greatest! Love you." while She is tucking you in for the night.
Although our breviary seems to offer us a menu of choices for this final marian prayer, it's also good to know that there is a traditional rubric for using the one that best fits with the liturgical season.
From Advent through the Christmas season, the traditional marian prayer is the Alma Redemptoris Mater: "Loving Mother of the Redeemer, gate of heaven, star of the sea,, etc."
For ordinary time--both the little patch of it that falls between Christmastide and lent, as well as the big patch between Pentecost and the start of advent, use the Salve Regina (Hail Holy Queen) Alternatively, continue with the Alma Redemptoris Mater until February 2nd, which in the traditional liturgy was the end of the extended Christmas season.
During lent, switch to the Ave Regina Caelorum: "Hail, O Mary Queen of heaven, Queen of all the saints and angels, root of Jesse, heaven's portal, etc." Although now that I look it up, I see that this one only appears in Latin in the Christian Prayer breviary. No problem--just pray it in Latin.
For the Easter Season, we use the lovely Regina Caeli: "Queen of Heaven, Rejoice, Alleluia!" Those of you who pray the noon Angelus probably know that this prayer is used in its stead during the Easter season.
Complete Latin and English translations of these four traditional marian antiphons, plus a bit of history on each one, can be found at this link to the Adoremus website.
For many years my husband and I have been chanting these antiphons using the "Simple Tones" version. If you would like to learn them, here is a page from the Chantblog with an audio file of the Alma Redemptoris Mater. On the bottom of that page you will find links for audio of the other ones as well.
It is true that the Liturgy of the Hours allows us to use any Marian antiphon we like after Night Prayer. But to choose them in accordance with the liturgical season is to participate in a beautiful and ancient custom. And not just ancient! This choice of marian antiphons, and these chant settings, are still used in many places, including monasteries, seminaries, and at the Vatican. So if you are looking for a New Year's resolution to enhance your practice of the Liturgy of the Hours, this might be the place to start.
