From the Catholic Encyclopedia:
The seven antiphons to the Magnificat in the ferial Office of the seven days preceeding the vigil of Christmas; so called because all begin with the interjection "O". Their opening words are: (1) "O Sapientia", (2) "O Adonai", (3) "O Radix Jesse", (4) "O Clavis David", (5) "O Oriens", (6) "O Rex Gentium", (7) "O Emmanuel".
Addressed to Christ under one or other of His Scriptural titles, they conclude with a distinct petition to the coming Lord (e. g.: "O Wisdom … come and teach us the way of prudence"; "O Adonai … come and redeem us by thy outstretched arm"; "O Key of David … come and lead from prison the captive sitting in darkness and in the shadow of death" etc.).
Couched in a poetic and Scriptural phraseology they constitute a notable feature of the Advent Offices. These seven antiphons are found in the Roman Breviary; but other medieval Breviaries added (1) "O virgo virginum quomodo fiet" (2) "O Gabriel, nuntius cœlorum", subsequently replaced, almost universally, by the thirteenth-century antiphon, "O Thoma Didyme", for the feast of the Apostle St. Thomas (21 December).
Some medieval churches had twelve greater antiphons, adding to the above (1) "O Rex Pacifice", (2) "O Mundi Domina", (3) "O Hierusalem", addressed respectively to Our Lord, Our Lady, and Jerusalem.
The Parisian Rite added two antiphons ("O sancte sanctorum" and "O pastor Israel") to the seven of the Roman Rite and began the recitation of the nine on the 15th of December.
Prose renderings of the Roman Breviary O's will be found in the Marquess of Bute's translation of the Roman Breviary (winter volume). Guéranger remarks that the antiphons were appropriately assigned to the Vesper Hour because the Saviour came in the evening hour of the world (vergente mundi vespere, as the Church sings) and that they were attached to the Magnificat to honour her through whom He came.
[The following isn't from the Catholic Encyclopedia, but of interest:] Some surmise that the Benedictine monks arranged these antiphons with a definite purpose. If one starts with the last title and takes the first letter of each of the O Antiphons - Emmanuel, Rex, Oriens, Clavis, Radix, Adonai, Sapientia - the Latin words ero cras are formed, meaning, “Tomorrow, I will come.”

The church of Milan today celebrates the feast of the martyr St Victor, a Christian soldier from the Roman province of Africa, who was killed in the first year of the persecution of Diocletian, 303 AD, while serving at Milan under the Emperor Maximian.

From the Encyclical Quamquam pluries of Pope Leo XIII on St Joseph, issued on the feast of the Assumption in 1889. It is providential that the conclave to elect a new pope should begin on this important solemnity; let us remember to count Joseph especially among the Saints to whom we address our prayers for a good outcome of this election. The spe...
Why the Traditional Mass Should Remain In LatinPeter Kwasniewski
In spite of attempts to suppress it, the traditional Latin Mass is here to stay. It may not be as widespread as it was in the halcyon days of Summorum Pontificum, but neither is it exactly hidden under a bushel, as the early Christians were during the Roman persecutions. In many cites, gigantic parishes run by former Ecclesia Dei institutes are pac...

The Feast of St Vincent FerrerGregory DiPippo
The feast of St Vincent Ferrer was traditionally assigned to the day of his death, April 5th, but I say “assigned to” instead of “kept on” advisedly; that date falls within either Holy Week or Easter week so often that its was either translated or omitted more than it was celebrated on its proper day. [1] For this reason, in 2001 the Dominicans mov...
Good Shepherd Sunday 2025Gregory DiPippo
Dearest brethren, Christ suffered for us, leaving you an example that you should follow His steps; Who did no sin, neither was guile found in His mouth; Who, when He was reviled, did not revile. When He suffered, he threatened not, but delivered Himself to him that judged Him unjustly; Who His own self bore our sins in His body upon the tree: that...
The Gospel of Nicodemus in the Liturgy of EastertideGregory DiPippo
By “the Gospel of Nicodemus”, I mean not the apocryphal gospel of that title, but the passage of St John’s Gospel in which Christ speaks to Nicodemus, chapter 3, verses 1-21. This passage has an interesting and complex history among the readings of the Easter season. For liturgical use, the Roman Rite divides it into two parts, the second of which...
“The Angel Cried Out” - The Byzantine Easter Hymn to the Virgin MaryGregory DiPippo
In the Byzantine Divine Liturgy, there are several places where the priest sings a part of the anaphora out loud, and the choir makes a response, while he continues the anaphora silently. In the liturgy of St John Chrysostom, which is by far the more commonly used of the two anaphoras, the priest commemorates the Saints after the consecration and ...
