The birth of St. Mary is celebrated by all traditional churches on September 8. The record of the birth of Mary is not found in the Bible. The traditional account of the event is taken from the apocryphal writings which are not part of the New Testament scriptures.
The traditional teaching which is celebrated in the hymns and verses of the festal liturgy is that Joachim and Anna were a pious Jewish couple who were among the small and faithful remnant—“the poor and the needy”—who were awaiting the promised messiah. The couple was old and childless. They prayed earnestly to the Lord for a child, since among the Jews barrenness was a sign of God’s disfavor. In answer to their prayers, and as the reward of their unwavering fidelity to God, the elderly couple was blessed with the child who was destined, because of her own personal goodness and holiness, to become the Mother of the Messiah-Christ.
The feast of the Nativity of the Holy Mother-of-God is a glorification of Mary’s birth, of Mary herself and of her righteous parents. It is a celebration as well of the very first preparation of the salvation of the world. For the “Vessel of Light,” the “Book of the Word of Life,” the “Door to the Orient,” the “Throne of Wisdom” is being prepared on earth by God Himself in the birth of the holy girl-child Mary.
On the feast of the Holy Mother-of-God, as on all liturgical celebrations of Christ’s Mother, we proclaim and celebrate that through God’s graciousness to mankind every Christian receives what Mary receives, the “great mercy” which is given to human persons because of Christ’s birth from the Virgin.
