Nativity of the Birth-Giver of God!
In addition to the celebration of the Annunciation, there are three major feasts in the Church honoring Mary, the Birth-Giver of God. The first of these is the feast of her Nativity which is kept on the 8/21 of September.
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.
Your birth, O Birth-Giver of God, brought joy to the whole world, for from you dawned the sun of righteousness, Christ our God. Freeing us from the curse, He gave us His blessings. Abolishing death, He granted us eternal life. (Troparion)
By your nativity,O most pure virgin, Joachim and Anna are freed from barrenness; Adam and Eve from the corruption of death. And we, your people, freed from the guilt of sin, celebrate and sing to you: The barren woman gives birth to the Birth-Giver of God, the Nourisher of our Life. (Kontakion)
