O antiphon

The O Antiphons are antiphons used at daily prayer in the evenings of the last days of Advent in various liturgical Christian traditions.
Each antiphon is a name of Christ, one of his attributes mentioned in Scripture. They are:
* December 17: O Sapientia (O Wisdom)
* December 18: O Adonai (O Adonai)
* December 19: O Radix Jesse (O Root of Jesse)
* December 20: O Clavis David (O Key of David)
* December 21: O Oriens (O Dayspring)
* December 22: O Rex Gentium (O King of the nations)
* December 23: O Emmanuel (O Emmanuel)
In the Roman Catholic tradition, the O Antiphons are sung or recited at Vespers from December 17 to December 23 inclusive (but see note below on alternative English usage). 
In the Church of England they have traditionally been used as antiphons to the Magnificat at Evening Prayer during this period, and although not printed in the Book of Common Prayer, have long been part of secondary Anglican liturgical sources, such as the English Hymnal. More recently they have found a place in primary liturgical documents throughout the Anglican Communion, including the Church of England's Common Worship liturgy. 
Use of the O Antiphons also occurs in many Lutheran churches.
The hymn O come, O come, Emmanuel (in Latin, Veni Emmanuel) is a lyrical paraphrase of these antiphons. 
The first letters of the titles taken backwards form a Latin acrostic of "Ero Cras" which translates to "Tomorrow, I will come", mirroring the theme of the antiphons.
==Origin==
According to Fr. William Saunders:Saunders, William, What are the "O Antiphons"?, CatholicEducation.org, retrieved 30 November 2009.
A number of other antiphons were found in various medieval breviaries.
==Analysis==
The importance of the "O Antiphons" is twofold. First, each one is a title for the Messiah. Secondly, each one refers to the prophecy of Isaiah of the coming of the Messiah. The Latin antiphons are from the Breviarium Romanum. The English versions, which are not always literal translations of the Latin, are from the Church of England's Common Worship liturgy. Biblical quotations are from the NRSV.
===O Sapientia===
Latin:
:O Sapientia, quae ex ore Altissimi prodiisti,
:attingens a fine usque ad finem,
:fortiter suaviterque disponens omnia:
:veni ad docendum nos viam prudentiae.
English:
:O Wisdom, coming forth from the mouth of the Most High,
:reaching from one end to the other mightily,
:and sweetly ordering all things:
:Come and teach us the way of prudence.
Isaiah had prophesied:
*"The spirit of the Lord shall rest on him, the spirit of wisdom and understanding, the spirit of counsel and might, the spirit of knowledge and the fear of the Lord. His delight shall be in the fear of the Lord." 
*"[...] he is wonderful in counsel, and excellent in wisdom."

This prophecy is also relevant in that it describes the Messiah as "coming forth from the mouth of the Most High", which is very significant in light of the Christian doctrine, rooted in the first chapter of the Gospel of John, according to which Jesus Christ, the Messiah, is the Incarnate Word of God the Father.
===O Adonai===
Latin:
:O Adonai, et Dux domus Israel,
:qui Moysi in igne flammae rubi apparuisti,
:et ei in Sina legem dedisti:
:veni ad redimendum nos in brachio extento.
English:
:O Adonai, and leader of the House of Israel,
:who appeared to Moses in the fire of the burning bush
:and gave him the law on Sinai:
:Come and redeem us with an outstretched arm.
Isaiah had prophesied:
*"[...] but with righteousness he shall judge the poor, and decide with equity for the meek of the earth; he shall strike the earth with the rod of his mouth, and with the breath of his lips he shall kill the wicked. Righteousness shall be the belt around his waist, and faithfulness the belt around his loins." 
*"For the Lord is our judge, the Lord is our ruler, the Lord is our king; he will save us."

===O Radix Jesse===
Latin:
:O Radix Jesse, qui stas in signum populorum,
:super quem continebunt reges os suum,
:quem Gentes deprecabuntur:
:veni ad liberandum nos, jam noli tardare.
English:
:O Root of Jesse, standing as a sign among the peoples;
:before you kings will shut their mouths,
:to you the nations will make their prayer:
:Come and deliver us, and delay no longer.
Isaiah had prophesied:
*"A shoot shall come out from the stock of Jesse, and a branch shall grow out of his roots." 
*"On that day the root of Jesse shall stand as a signal to the peoples; the nations shall inquire of him, and his dwelling shall be glorious." 
Jesse was the father of King David, and Micah had prophesied that the Messiah would be of the house and lineage of David and be born in David's city, Bethlehem . Also compare , and .
===O Clavis David===
Latin:
:O Clavis David, et sceptrum domus Israel;
:qui aperis, et nemo claudit;
:claudis, et nemo aperit:
:veni, et educ vinctum de domo carceris,
:sedentem in tenebris, et umbra mortis.
English:
:O Key of David and sceptre of the House of Israel;
:you open and no one can shut;
:you shut and no one can open:
:Come and lead the prisoners from the prison house,
:those who dwell in darkness and the shadow of death.
Isaiah had prophesied:
*"I will place on his shoulder the key of the house of David; he shall open, and no one shall shut; he shall shut, and no one shall open." 
*"His authority shall grow continually, and there shall be endless peace for the throne of David and his kingdom. He will establish and uphold it with justice and with righteousness from this time onwards and for evermore." 
*"...To open the blind eyes, to bring out the prisoners from the prison, and them that sit in darkness out of the prison house.".
===O Oriens===
Latin:
:O Oriens,
:splendor lucis aeternae, et sol justitiae:
:veni, et illumina sedentes in tenebris, et umbra mortis.
English:
:O Rising Sun,
:splendour of light eternal and sun of righteousness:
:Come and enlighten those who dwell in darkness and the shadow of death.
Isaiah had prophesied:
*"The people who walked in darkness have seen a great light; those who lived in a land of deep darkness—on them light has shined." 
Also compare and ; Ml 3,20
===O Rex Gentium===
Latin:
:O Rex Gentium, et desideratus earum,
:lapisque angularis, qui facis utraque unum:
:veni, et salva hominem,
:quem de limo formasti.
English:
:O King of the nations, and their desire,
:the cornerstone making both one:
:Come and save the human race,
:which you fashioned from clay.
Isaiah had prophesied:
*"For a child has been born for us, a son given us; authority rests upon his shoulders; and he is named Wonderful Counsellor, Mighty God, Everlasting Father, Prince of Peace." 
*"He shall judge between the nations, and shall arbitrate for many peoples; they shall beat their swords into ploughshares, and their spears into pruning-hooks; nation shall not lift up sword against nation, neither shall they learn war anymore." 
Also compare and 
===O Emmanuel===
Latin:
:O Emmanuel, Rex et legifer noster,
:exspectatio Gentium, et Salvator earum:
:veni ad salvandum nos, Domine, Deus noster.
English:
:O Emmanuel, our king and our lawgiver,
:the hope of the nations and their Saviour:
:Come and save us, O Lord our God.
Isaiah had prophesied:
*"Therefore the Lord himself will give you a sign. Look, the young woman is with child and shall bear a son, and shall name him Immanuel." 
(Emmanuel means God is with us).
==Alternative English Usage==
Although the antiphons and dates shown above have been fairly universally recognised throughout western Christendom, an alternative English medieval practice arose of moving all of the antiphons forward by one day (commencing therefore on 16 December) and adding an additional (eighth) antiphon on 23 December, with the acrostic thus becoming Vero cras, "truly, tomorrow". This is the antiphon O Virgo virginum (O Virgin of virgins), with the following text:
Latin:
:O Virgo virginum, quomodo fiet istud?
:Quia nec primam similem visa es nec habere sequentem.
:Filiae Jerusalem, quid me admiramini?
:Divinum est mysterium hoc quod cernitis.
English:
:O Virgin of virgins, how shall this be?
:For neither before thee was any like thee, nor shall there be after.
:Daughters of Jerusalem, why marvel ye at me?
:The thing which ye behold is a divine mystery.
Given the English origins of this alternative, it has traditionally been the version used in the Church of England (including Canterbury Cathedral) until modern times, and is the version printed in traditional Church of England liturgical sources including the English Hymnal and New English Hymnal. From 2000, however, the Church of England appears to have taken an official step away from English medieval practice towards the more universal norm, as Common Worship makes provision for the sevenfold version of the antiphons, and not the eightfold version.
==Antiphons on the Benedictus==
Accompanying the O Antiphons are two Antiphons said at Lauds, on December 21 and 23, also relating to the theme of the upcoming birth of Christ. The first, due to the feast of St Thomas falling on December 21, is traditionally used instead in the commemoration of the feria. With the transference of this feast to July 3 in the revised calendar, these are again used in the Liturgy of the Hours as antiphons. The Monday through Saturday which fall on the days of the O Antiphons also have their own antiphons for the psalms of Lauds, rather than repeating the antiphons of the previous Sunday, as is otherwise done in Advent.
===December 21===
Nolite timere: quinta enim die veniet ad vos Dominus noster.
:Fear not, for on the fifth day our Lord will come to you.
===December 23===
Ecce completa sunt omnia, quae dicta sunt per Angelum de Virgine Maria.
:Behold, all things are fulfilled, which were spoken by the Angel to the Virgin Mary.
==Musical settings==
Marc-Antoine Charpentier completed a setting of the O antiphons in the early 1690s. In the twentieth century, the Estonian composer Arvo Pärt set a German translation of these antiphons for SATB unaccompanied choir, under the title Magnificat Antiphonen. The British composer Bob Chilcott has set the Latin version of these antiphons for SSAATTBB unaccompanied choir, under the title Advent Antiphons.
