The Solemnity of Mary, Holy Mother of God is a liturgical celebration observed on January 1st which falls exactly one week after Christmas, the end of the octave of Christmas.
The Blessed Virgin Mary is honored as the Mother of God because she conceived and gave birth to Christ, who is the incarnation of God the Son, the Second Person of the Blessed Trinity. It is fitting to honor Mary as Mother of Jesus, following the birth of Christ. When Catholics celebrate the Solemnity of Mary Mother of God, we are not only honoring Mary, who was chosen among all women throughout history to bear God incarnate, but we are also honoring our Lord, who is fully God and fully human.
Since the first centuries of Christianity, the Church customarily has regarded the Blessed Virgin Mary to be the Mother of God for a simple, logical reason;
By the power of the Holy Spirit, she conceived Jesus Christ, the Son of God.
Since the divine Person, God the Son, assumed, or took on, human nature, she is the Mother of God in the fullest since: "What the Catholic faith believes about Mary is based on what it believes about Christ, and what it teaches about Mary illumines in turn its faith in Christ" (CCC 487). The Church solemnly defined this belief at the Ecumenical Council of Ephesus AD 431.
Consider how we speak of human motherhood. Our own mothers supply our human nature, our physical bodies; yet, it is God who supplies our spirit and soul. We do not distinguish between the two: a mother gives birth not only to our nature, but to our entire person.
In regard to Christ, the Blessed Virgin Mary supplied his humanity and is thus the Mother of Jesus. But Christ has both a human nature and a divine nature. Nevertheless, she gave birth to the one Person who is Jesus Christ, the Son of God made man. She is rightly called the Mother of God even though she herself is not the source of his divinity. (Cf. CCC 496)
This doctrine is taught implicitly in Scripture, especially in those passages where the Blessed Virgin Mary is called the"Mother of Jesus", or the"Mother of Christ"—perhaps most strikingly when Saint Elizabeth greets her with the following words: "Why is this granted me, that the mother of my Lord should come to me?" (Luke 1:43, emphasis added). Her identity as the Mother of God is intimately linked to Christ's own identity as fully man and fully God, the Son of God. (Cf. CCC 509)
