The Solemnity of Mary, Mother of God, is a liturgical celebration observed on January 1. The use of the word “solemnity” here is not a statement about Mary’s personality. It is a designation used for certain days within the liturgical (church-based) calendar of the Church. Solemnities are the highest rank of liturgical celebration, higher than feast days or memorials. By celebrating a solemnity dedicated to Mary’s motherhood, the Church highlights the significance of her role in the life of Christ. Though New Year’s Day may seem more like a day for football and hangovers than for Mary, there’s a beautiful spiritual significance in celebrating her during the heart of the Christmas season. Pope Paul VI, in his apostolic exhortation Marialis Cultus (1974), called the Solemnity of Mary “a fitting occasion for renewing adoration of the newborn Prince of Peace, for listening once more to the glad tidings of the angels (Luke 2:14), and for imploring from God, through the Queen of Peace, the supreme gift of peace.”
