In those days Mary arose and went with haste into the hill country, to a city of Judah, and she entered the house of Zechariah and greeted Elizabeth. And when Elizabeth heard the greeting of Mary, the babe leaped in her womb; and Elizabeth was filled with the Holy Spirit and she exclaimed with a loud cry, “Blessed are you among women, and blessed is the fruit of your womb! And why is this granted me, that the mother of my Lord should come to me? For behold, when the voice of your greeting came to my ears, the babe in my womb leaped for joy. And blessed is she who believed that there would be a fulfilment of what was spoken to her from the Lord.”
And Mary said, “My soul magnifies the Lord, and my spirit rejoices in God my Savior.” — Luke 1:39-47
John the Baptist was born again before he was born the first time, as it were, being sanctified in the womb. Elizabeth is also fill with the Holy Spirit. Jesus, the Divine Son of the Living God is there, Body Blood Soul and Divinity in the womb of Mary, rendering His first miracle of grace.
The Church celebrates the birthdays only of Jesus (God), Mary (immaculately conceived) and John, sanctified in the womb. There have been a few temporary exceptions to this, what with the exuberance of people rejoicing in the lives of the saints.
But, as it is, the rest of us are all born in sin, original sin. Personal sin might come along later if we survive that long in this sorry world. For this reason, still in living memory much of the world outside of these United States has not so much celebrated birthdays as “name days”, that is, the day of one’s baptism with the name one received or which was affirmed at that time, now in the sanctifying grace of the indwelling of the Most Holy Trinity, which presence brings about the forgiveness of original sin and any personal sin.
Today’s my own birthday, the big 60, pulling 50, pushing 70, black balloons. All that. Strange thing, birthdays, for us, I mean. Do we celebrate being born utter heathens? Of course, after her labor pains, a woman rejoices that a man is born into the world, but…
Stepping back from all this, yes, we can celebrate birthdays even of utterly heathen wretched blackened by original sin babies such as I was when “brought to the light” as the rest of the world calls the event of being born. We are to see that our Lord has redeemed all, and will bring salvation to those who (all things being equal) desire to be saved. We are to see with joy that our Lord is bringing his love even to us all while we are yet in sin as the Good Book says.
Meanwhile… stepping waaaaaaaaaaaaay back, seeing the even bigger picture, when Mary’s soul magnifies the Lord, her Savior, He having looked upon the lowliness of His handmaid, He having done great things for her, she is also thanking Him for bringing us to the light also by way of her intercession in view of His redemption of all of us. To use Saint Paul’s terminology, Jesus, the Son of Mary, is the Head of the Body of Christ, and we the members of the Body of Christ. None of this would have come about if Mary had not said Yes to the announcement of the angel that she was to be the Immaculate Virgin Mother of God.
But stepping waaaaaaaaaaaaaaay back, we find that we are right in the midst of Him who is All in all (St Paul again). From my own non-immaculate condition, having been subject to original sin, having my own rubbish sin, in my own remotely analogous way I also, we also, can repeat that magnificat of Mary, you know, in her honor. A flower for you, Mary.
