Prayers for Mama Mary's Nativity

As to prayer, this one to Maria Bambina (the Baby Mary) is most apt:

Hail, Infant Mary, full of grace, the Lord is with thee, blessed art thou forever, and blessed are thy holy parents Joachim and Anne, of whom thou wast miraculously born. Mother of God, intercede for us.

We fly to thy patronage, holy and amiable Child Mary, despise not our prayers in our necessities, but deliver us from all dangers, glorious and blessed Virgin.

V. Pray for us, holy Child Mary.

R. That we may be made worthy of the promises of Christ.

Let us Pray: O almighty and merciful God, Who through the cooperation of the Holy Ghost, didst prepare the body and soul of the Immaculate Infant Mary that she might be the worthy Mother of Thy Son, and didst preserve her from all stain, grant that we who venerate with all our hearts her most holy childhood, may be freed, through her merits and intercession, from all uncleanness of mind and body, and be able to imitate her perfect humility, obedience and charity. Through Christ Our Lord. Amen.

There is also this marvelous prayer in honour of Our Lady's Nativity, written by St. Anselm:

Vouchsafe that I may praise thee, O sacred Virgin; give me strength against thine enemies, and against the enemy of the whole human race. Give me strength humbly to pray to thee. Give me strength to praise thee in prayer with all my powers, through the merits of thy most sacred nativity, which for the entire Christian world was a birth of joy, the hope and solace of its life.

When thou wast born, O most holy Virgin, then was the world made light.

Happy is thy stock, holy thy root, and blessed thy fruit, for thou alone as a virgin, filled with the Holy Spirit, didst merit to conceive thy God, as a virgin to bear Thy God, as a virgin to bring Him forth, and after His birth to remain a virgin.

Have mercy therefore upon me a sinner, and give me aid, O Lady, so that just as thy nativity, glorious from the seed of Abraham, sprung from the tribe of Juda, illustrious from the stock of David, didst announce joy to the entire world, so may it fill me with true joy and cleanse me from every sin.

Pray for me, O Virgin most prudent, that the gladsome joys of thy most helpful nativity may put a cloak over all my sins.

O holy Mother of God, flowering as the lily, pray to thy sweet Son for me, a wretched sinner. Amen.

5 Points on Mama Mary's Nativity

In the light of our Mother's birthday, we take a look at some of the highlights surrounding Mama Mary's nativity:

1. There is nothing contained in Scripture about the birth of Mary or her parentage, though Joseph's lineage is given in the first chapter of the Gospel of Matthew. The names of Mary's parents, Joachim and Anna, appear in the apocryphal "Gospel of James", a book dating from the 2nd Century AD, not part of the authentic canon of Scripture. According to this account, Joachim and Anna were also beyond the years of child-bearing, but prayed and fasted that God would grant their desire for a child.
2. The Feast of the Nativity of the Blessed Virgin Mary was celebrated at least by the sixth century, when St. Romanos the Melodist, an Eastern Christian who composed many of the hymns used in the Eastern Catholic and Eastern Orthodox liturgies, composed a hymn for the feast. The feast spread to Rome in the seventh century, but it was a couple more centuries before it was celebrated throughout the West.
3. The Feast of the Birth of the Blessed Virgin Mary has been celebrated in the Church at least since the 8th Century.
4. The Church's calendar observes the birthdays of only two saints: Saint John the Baptist (June 24), and Mary, Mother of Jesus.
5. The birth of Mary was miraculous. She was conceived without sin as a special grace because God had selected her to become the mother of His Son (the feast of her Immaculate Conception is celebrated on December 8). The dogma of the Immaculate Conception of the Virgin Mary, though generally believed throughout the Church for many centuries, was formally declared by Pope Pius IX in 1854.
