January 1 is a Holy Day of Obligation for Roman Catholics. Not because it is New Year's day, but because it is the octave (8th day) of Christmas. This feast of Mary, the Mother of God, brings home the reality of the incarnation. In Jesus, the Creator truly became man. And that man had, and still has, a mother. So affirmed the Ecumenical Council of Ephesus in AD 431.
