Dec 31 - 9pm Vigil of Mary Mother of God

On Dec 31 we will have our normal 11am Sunday Mass, and then a 9pm Vigil Mass for the Solemnity of Mary Mother of God. MDM will be closed on January 1.

From the United States Council of Catholic Bishops: Since the Solemnity of Mary the Holy Mother of God on January 1, 2018 falls on a Monday this year, it is not observed as a Holy day of Obligation.
