It is curious that every year the Feast of the Nativity of Our Lady becomes such a big and affectionate celebration among Catholics, even though, whether we realise it or not, it is not actually her paramount feast. That place belongs more properly to the Assumption, when Our Lady was taken body and soul into heavenly glory. Perhaps part of the reason is that birthdays are something immediately familiar to us, and so we naturally approach 8 September with the same sort of sentiment with which we celebrate birthdays in ordinary life. There is, of course, absolutely nothing wrong with greeting Our Lady a happy birthday or showing our affection for her in that way. But the Church is not celebrating her Nativity merely because Mary happened to be born on this day. The very fact that her earthly birth is given a place in the liturgical calendar points to something much deeper.
The Church celebrates only three earthly birthdays in Her calendar: that of Our Lord Jesus Christ, Our Lady, and of St John the Baptist. And the simplest reason is this: ALL THREE ENTERED THE WORLD WITHOUT SIN. Our Lord, of course, is God made man and was entirely without sin. Our Lady had been preserved from original sin from the very first instant of her conception. St John the Baptist, according to the ancient tradition of the Church, was sanctified while still in his mother’s womb at the Visitation. In other words, when each of these three was born into the world, there was no stain of original sin upon them. Notice, by contrast, that the earthly birthdays of the other saints are not celebrated in the liturgical calendar. They, like the rest of us, entered this world bearing original sin and had need of the grace of Baptism. The day the Church ordinarily remembers as their dies natalis—their “birthday”—is instead the day of their death: the day on which they were born from this earthly life into the life of heaven.
And that makes the way we speak of Our Lady’s “birthday” rather different from the ordinary meaning we give that word. What is remarkable about 8 September is not merely that Mary came into the world on this day; rather, it is that her earthly birth was far greater and more glorious than ours.
