January 1 - Solemnity of Mary, Mother of God

The solemnity of the 1 January, an eminently Marian feast, presents an excellent opportunity for liturgical piety to encounter popular piety: the first celebrates this event in a manner proper to it; the second, when duly catechised, lends joy and happiness to the various expressions of praise offered to Our Lady on the birth of her divine Son, to deepen our understanding of many prayers, beginning with that which says: "Holy Mary, Mother of God, pray for us, sinners". (Directory on Popular Piety and the Liturgy, 115).

Called in the Gospels "the Mother of Jesus," Mary is acclaimed by Elizabeth, at the prompting of the Spirit and even before the birth of her son, as "the mother of my Lord." In fact, the One whom she conceived as man by the Holy Spirit, who truly became her Son according to the flesh, was none other than the Father's eternal Son, the second person of the Holy Trinity. Hence the Church confesses that Mary is truly "Mother of God" - Catechism of the Catholic Church 495

"In celebrating this annual cycle of the mysteries of Christ, Holy Church honors the Blessed Mary, Mother of God, with a special love. She is inseparably linked with the saving work of her Son. In her the Church admires and exalts the most excellent fruit of redemption and joyfully contemplates, as in a faultless image, that which she herself desires and hopes wholly to be." - Catechism of the Catholic Church 1172

"Mary, the all-holy ever-virgin Mother of God, is the masterwork of the mission of the Son and the Spirit in the fullness of time. For the first time in the plan of salvation and because his Spirit had prepared her, the Father found the dwelling place where his Son and his Spirit could dwell among men. In this sense the Church's Tradition has often read the most beautiful texts on wisdom in relation to Mary. Mary is acclaimed and represented in the liturgy as the "Seat of Wisdom."
