The Liturgy of The Nativity of the Blessed Virgin Mary
The feast of the Nativity of the Blessed Virgin Mary, kept on the 8th of September, shines in the Tridentine liturgy with a unique and tender joy. It is one of only three earthly birthdays celebrated in the Church’s calendar: that of Our Lord, Our Lady, and St. John the Baptist. This singular honour marks Mary’s nativity as intimately bound to the economy of salvation, for her coming into the world was the dawn that heralded the Sun of Justice.
Dom Prosper Guéranger describes it in The Liturgical Year: “Mary comes into the world, not to eclipse the splendour of her Son, but to prepare for Him a throne, a temple, and a mother’s arms. The Church, therefore, in celebrating her birth, is celebrating the proximate advent of our Redeemer.”
In the Roman Missal of St. Pius V, the Mass formulary Nativitas Beatae Mariae Virginis begins with the Introit Gaudeamus omnes in Domino. The joyful tone reflects the universality of the mystery: all creation rejoices, for from this humble child of Joachim and Anne comes the one whom the Fathers call the “Living Ark” and “Gate of Heaven.”
Fr. Martin von Cochem, following Goffine’s Explanation of the Epistles and Gospels, notes the theological depth of this commemoration: “Though the Nativity of Mary be not directly a mystery of our Redemption, it is, nevertheless, most closely united with it. For without Mary, the Mediatrix of grace, the Incarnation of the Son of God would not have taken place. Thus her birth is the beginning of the accomplishment of the promises.”
Baur, in his meditations on the liturgical year, emphasizes that the humility of Mary’s origins is no hindrance to her exaltation, but rather the precondition of it: “She appears as the child of ordinary parents, Joachim and Anne, unknown to the world, yet predestined by God to a dignity beyond angels. The feast recalls to us that God raises up His chosen in hiddenness, preparing the greatest works in silence.”
The Collect of the day prays: Da, quaesumus, famulis tuis caelestis gratiae munera: ut, quibus Beatae Mariae Virginis partus exstitit salutis exordium, Nativitatis ejus votiva solemnitas pacis tribuat incrementa. The liturgy thus makes clear that her nativity was the “beginning of salvation,” for in her the plan of God took flesh in preparation.
Fr. Gabriel of St. Mary Magdalen, OCD, reflecting on the feast, writes in Divine Intimacy: “Let us contemplate Mary as a newborn babe: pure, holy, lovely, full of grace. Already her soul, adorned with sanctifying grace from the first instant of her conception, is resplendent before the gaze of God. Today is the aurora preceding the rising Sun. If we love Jesus, we cannot but rejoice at the birth of her who was to give Him to us.”
The Epistle, taken from the Book of Wisdom (Eccli. 24), places on Mary’s lips the words of Eternal Wisdom: “Ab initio, et ante saecula creata sum, et usque ad futurum saeculum non desinam.” The Church reads these verses in the Marian sense: Mary is from all eternity chosen, though in time she was born, that she might be Mother of the Eternal Word.
The Gospel (Matt. 1:1–16) recounts the genealogy of Christ. Guéranger remarks: “This table of names, which might seem dry, is in truth a hymn of praise to the fidelity of God, who through the long centuries prepared the virginal stem from which the Flower of Jesse would spring. At its end appears Mary, the summit of the generations, in whom all expectation is fulfilled.”
Thus the Tridentine liturgy of this feast joins heaven and earth in rejoicing. It is not only the commemoration of a birthday, but the liturgical proclamation that God’s promises never fail, and that His greatest works come in hiddenness and humility. The faithful, kneeling before the altar clothed in white vestments, perceive that in Mary’s nativity begins our own hope: the advent of redemption, the dawn of Christ. 🔝

Spiritual Reflection: for the Nativity of the Blessed Virgin Mary
The Church, in her ancient wisdom, does not lavishly celebrate the birthdays of all the saints. Their dies natalis, the day of their death, is ordinarily honoured, for it marks their birth into eternal life. Yet three births are celebrated upon earth with solemn feast: that of Our Lord Jesus Christ, the Word made flesh; that of St John the Baptist, sanctified in his mother’s womb; and that of Mary, the Immaculate Virgin.
This singularity points us to a mystery: her nativity was not an ordinary beginning but the dawn of salvation. Dom Guéranger teaches: “Mary comes into the world, not for herself, but for Him whose Mother she is to be. She is the dawn which precedes the Sun of Justice, and announces His rising.” In Mary’s birth, hidden in a humble house, the long silence of the prophets begins to give way to fulfilment.
The Roman liturgy makes this clear. The Introit Gaudeamus omnes in Domino exhorts all creation to rejoice, for the child born of Joachim and Anne is no mere daughter of Israel, but the living temple in whom God Himself will dwell. The Collect declares that her birth is salutis exordium—the beginning of salvation. Thus the Church dares to speak of this day not only in relation to Mary but in relation to Christ, for all that is in her exists for Him.
Fr. Gabriel of St Mary Magdalen reflects: “Today is the aurora preceding the rising Sun. If we love Jesus, we cannot but rejoice at the birth of her who was to give Him to us.” In contemplating Mary as a child, we see sanctity clothed in littleness. Though she is full of grace, she lies as all infants do, in helpless dependence. God reveals His strength in weakness and His majesty in humility.
The Epistle from Ecclesiasticus places upon her lips the words of Wisdom: “From the beginning, and before the world, was I created.” Here the Church dares to express her eternal predestination. Long before her birth, Mary was foreseen and chosen, immaculate in her conception, prepared as the spotless Mother of the Redeemer. Baur observes: “God raises up His chosen in hiddenness, preparing the greatest works in silence.” The genealogy in the Gospel, which might seem to our modern ears a mere list of names, is in truth a hymn to divine fidelity. It culminates in Mary, in whom the promises to Abraham and David reach their fulfilment.
What lessons does this feast offer us? First, it teaches the primacy of God’s hidden work. As the world’s powers turned upon their wheels of ambition, in a quiet home in Nazareth a child was born whose name would scarcely have been known. Yet in her, the destiny of the universe was taking shape. This is how God works: not through noise and spectacle, but through fidelity, littleness, and humility.
Secondly, the feast teaches us joy. Even before the Incarnation, the Church dares to sing Gaudeamus. Mary’s birth is not yet our redemption, but it is its beginning, and hope itself is cause for rejoicing. So too in our lives: when God plants a seed of grace, though its fruit be yet unseen, the seed is itself a reason for joy and thanksgiving.
Lastly, the feast teaches us to look upon Mary as mother and model. Goffine reminds us: “She is our Mother because she gave us the Saviour; she is our model because she is the first and most faithful disciple.” If we wish to walk in the path of Christ, we must begin with her, for she is the “Gate of Heaven.”
Therefore, as we kneel before the altar clothed in white, let us ask for the grace to imitate the Virgin’s humility and to rejoice in God’s hidden workings. In her nativity we find the beginning of our own salvation; in her birth, the dawning of eternal life.
