On December 17th, the Church’s Advent liturgy begins to focus in a particular way on the Nativity of the Lord. The prayers, readings, and preface at Mass as well as the readings, antiphons for the Gospel canticles, intercessions, and prayers at the Liturgy of the Hours concentrate more resolutely on the coming feast of the Nativity of the Lord than they did during the preceding days of Advent.
The great “O Antiphons” have a particular role in these days as they have been used for centuries as the antiphons for the Magnificat. Each antiphon, always sung in a very similar melody, begins with a title of Christ, usually taken from the Old Testament, and is followed by the petition that he come to us (veni) and act on our behalf:
December 17: O Sapientia (O Wisdom)
December 18: O Adonai (O Lord)
December 19: O Radix Iesse (O Root of Jesse)
December 20: O Clavis David (O Key of David)
December 21: O Oriens (O Daystar) [after this date, the days begin to get longer]
December 22: O Rex Gentium (O King of the Nations)
December 23: O Emmanuel (O God-with-Us)
When taken together from the last title to the first, the first letters of each title form the wonderful Latin acrostic:
Emmanuel
Rex
Oriens
Clavis
Radix
Adonai
Sapientia
As such, they form the Lord’s response to the Church’s ardent petition that he come (veni):
Ero cras (I will be there tomorrow)!
Below are some reflections on the various “O Antiphons”.
O Sapientia
The O Antiphons, which celebrate the incarnation of the Word of God who comes to make all things new, begin with the invocation of that Word as the very Wisdom of the Father. O Sapientia, O Wisdom, is personified in the Old Testament. We read in Sirach 24:3 exactly what we sing about at the beginning of this antiphon. Wisdom came forth from the mouth of the Most High and mist like covered the earth. We celebrate that same Wisdom who fixed his abode in Zion and who in the chosen city was given his rest. In the second part of the antiphon, Wisdom 8:1 is referenced which sings of that Wisdom which reaches from end to end mightily and governs all things well. In the Advent mystery, we celebrate and long for the Son of God who has gone forth from the Most High and who enters into our world for our salvation. Creative wisdom comes to create anew. It is this Wisdom of God who orders all things strongly and sweetly. We pray that he come (veni) and teach us the way of prudence, the virtue, as we read in the Catechism of the Catholic Church, that disposes practical reason to discern our true good in every circumstance and to choose the right means of achieving it. Prudence is, therefore, known as the auriga virtutum (the charioteer of the virtues) as it guides the other virtues by setting rule and measure.
O Adonai
This antiphon considers Christ more specifically as Adonai, the God of the Covenant, and the Ruler of the house of Israel. O Adonai focuses on Christ’s divine nature and speaks of how Christ himself appeared to Moses in the burning bush and gave him the Law on Mount Sinai. In Exodus 3:7-10, we read that God called out to Moses from the burning bush and told him that he witnessed the affliction of his people in Egypt, that he heard their cry of complaint against their slave drivers, and that he knew well what they were suffering. He, therefore, tells Moses that, for that very reason, he has come down to rescue them and lead them out of Egypt into a good and spacious land, a land flowing with milk and honey. In the Advent mystery, we encounter Christ who as God comes to rescue his people from slavery and lead them into freedom. He takes them from the drudgery of slavery to the freedom of divine worship, in the words of the Benedictus: he set us free from the hands of our enemies, free to worship him without fear, holy and righteous in his sight all the days of our life. We pray that he come (veni) and redeem us with outstretched arm. The Church, then, rejoices in the power of God, evident in the Incarnation, to save his people, bringing them from slavery to the freedom of the very children of God.
O Radix Iesse
The symbol of the root of Jesse forms the context for the antiphon O Radix. In the Book of the Prophet Isaiah, in Isaiah 11:1 we read that a shoot shall sprout from the stump of Jesse, and that from his roots a bud shall blossom. Further on, Isaiah 11:10 states that on that day the root of Jesse set up as a signal for the nations, the Gentiles shall seek out, for his dwelling shall be glorious. Finally, Isaiah 52:15 reveals that because of him kings shall stand speechless. Both the lowliness and the glory of the kingdom are present here. The Davidic kingdom was dethroned with the Babylonian exile, but the stump of Jesse, the father of David, will again spring forth and serve as a banner for the nations. The Incarnation begins in this world in lowliness and poverty, but for those with the eyes of faith, the dwelling of the Lord in the womb of the Virgin Mary is nothing if not glorious. In the Advent mystery, the growth of the Kingdom becomes apparent. From humble and unimpressive beginnings, the Kingdom becomes a unifying banner around which people of every race and tongue gather, as the hymn for Evening Prayer for the feast of the Exaltation of the Holy Cross states: Vexilla regis prodeunt/The royal banners forward go. We pray that our Lord come (veni) and not delay and free us from all those things that keep the Kingdom from truly blossoming in our lives—or as we pray more directly in the Our Father: thy Kingdom come.
O Clavis David
The power of Christ, and therefore, the definitive deliverance of the People of God from the power of the Evil One becomes more evident in the antiphon O Clavis. Christ, who identifies himself as the First and the Last, the One who lives, and the one who holds the keys of death and the nether world, speaks in Revelation 3:7 of himself as the Key of David the holy and the true One, who wields David’s key, who opens and no one can shut, who shuts and no one can open. In the Advent mystery, Christ comes as the undisputed ruler of heaven and earth and the one who has given the power of the keys to Peter. As we read in Matthew 16:18-19: You are Peter, and upon this rock, I will build my church, and the gates of the nether world shall not prevail against it. I will give you the keys of the kingdom of heaven. Whatever you bind on earth shall be bound in heaven. Whatever you loose on earth shall be loosed in heaven. We pray that the Lord come (veni) and lead out of captivity those who are bound in prison and those who sit in darkness and the shadow of death.
O Oriens
As the birth of the Savior approaches and as the days are about to get longer, O Oriens, becomes a panegyric on Christ the light of the world (John 8:12), whom we proclaim in the Nicene Creed as, light from light and true God from true God. The incarnate divine light is born in the darkness of our world, and as December 21st is the shortest day of the year, Christ appears as the true Sol Invictus, the true Unconquered Sun. He is the Oriens ex alto/the dawn from on high whom the Church celebrates every morning in the Benedictus. The Advent mystery makes real what one reads in Wisdom 7:26, that Wisdom (recall O Sapientia on December 17) is a reflection of eternal light, the spotless mirror of the power of God, the image of his goodness. As we prayed yesterday in O Clavis, we pray again today that the Lord come (veni) and enlighten those who sit in darkness and the shadow of death, but we cannot do this without recalling again the Benedictus which concludes with the words illuminare his, qui in tenebris et in umbra mortis sedent, ad dirigendos pedes nostros in viam pacis/enlighten those who sit in darkness and the shadow of death and guide our feet into the way of peace.
O Rex Gentium
The will of God that all may be saved shines forth in O Rex Gentium, and one cannot help but recall with joy and gratitude that the Roman Martyrology two days later, on December 24th, is going to celebrate the feast of Adam and Eve, the progenitors of the human race. The text of the Martyrology on December 24th is itself remarkable: The commemoration of all the holy ancestors of Jesus Christ, Son of David, Son of Abraham, Son of Adam, that is to say the ancestors who pleased God and were found just and who died in faith—those who did not receive the promises but who beheld them and greeted them from afar, of whom Christ was born according to the flesh and who is God over all things and blessed for ever. Already, Jeremiah 10:7 asked who would not fear you, O King of the Nations. Again, Ephesians 2:11-22 relates how both Jew and Gentile have been brought near through the blood of Christ, and how Christ broke down the barrier of hostility that kept them apart, and that they form a building with Christ Jesus himself as the capstone. The Advent mystery celebrates the power of that blood poured out for our salvation, the blood already coursing through the infant Christ about to be born, the blood that he inherited from all of his ancestors, and which he gives to us in the Eucharist. With good reason, we pray that he come (veni) and save all people, both Jew and Gentile, whom he formed from the dust of the earth.
O Emmanuel
Already, Isaiah 7:14 had prophesied that the virgin would be with child and bear a son and shall name him Emmanuel. Then again, in Matthew 1:23 we read how the Lord appeared in a dream to Joseph and told him that what had been said through the prophet would be fulfilled in the Virgin Mary. So it is that Emmanuel, God with us, is the object of our longing; but through the incarnation he has come to dwell among us in a way beyond all our imagining. Isaiah 33:22 had already referred to him as king and lawgiver, but the birth of the Virgin Mary’s Son meant yet more. In his Dogmatic Tome to Flavian, Pope Saint Leo the Great wrote that in the new order there was a new nativity. He who was invisible in his own nature became visible in ours; he who is true God is also true man. In him, the humility of humanity and the loftiness of the godhead both meet. The Advent-Christmas mystery is the mystery of the incarnation of the Son of God so that he may be one with us, sharing in our suffering and death so that we may share in the very life of God who cannot die. So, we pray with utmost confidence and gratitude (veni), come to save us, O Lord our God—and it happens in a way beyond all imagining.
