Mary, the Mother of God! This is a title which we would have thought impossible for any creature to possess. How could a creature become the mother of her Creator? By becoming man in the womb of the Virgin Mary God lost nothing of his Godhead. Instead, he took on human nature while retaining his divine nature. Being born, then, of the Virgin Mary, she became the Mother of God.
"The Virgin Mary, who at the message of the angel received the Word of God in her heart and in her body and gave life to the world, is acknowledged and honored as being truly the Mother of God and of the redeemer. Redeemed, in a more exalted fashion, by reason of the merits of her Son and united to him by a close and indissoluble tie, she is endowed with the high office and dignity of the Mother of the Son of God, and therefore she is also the beloved daughter of the Father and the temple of the Holy Spirit..." (Lumen Gentium 53)
How awesome it is that God should take on our human nature so that we could become his sons and daughters, and live with him forever in Heaven! Yet we know from sacred Scripture that this was not without great love and sacrifice. Thanks to Mary's "yes" to take on this role as Mother of God, Mother of the Redeemer, and our mother; to Joseph's "yes" to provide for the Child and his mother; and especially Christ's "yes" to the will of his Father, we know that through Christ all humankind is redeemed. Now it is our turn to say, "Yes, here am I, Lord; I come to do your will."
As Mother of God, Mary is not God; she remains a handmaid and an intercessor for all who call upon her. "Holy Mary, Mother of God, pray for us sinners, now and at the hour of our death. Amen."
