Immaculate Conception of Mary – December 9


Monday, December 9, is the Patronal Feast Day of the United States of America, the Immaculate Conception of the Blessed Virgin Mary. Since this year, the feast falls on the day after our Sunday obligation for the Second Sunday of Advent, it is not a Holy Day of Obligation. However, all are invited to attend our regular morning Mass at 8 AM or our All School Mass at 1:45 PM.

To be sure you are not confused about what this day celebrates, we recall that Saints Anne and Joachim, Mary’s parents, conceived her without original sin. Mary, chosen by God to be the mother of Jesus, was perfect from the moment of her conception. Pope Pius IX declared this a dogma of the Church in 1854. Nine months from now, we will celebrate the birth of Mary on September 8. This feast, however, is a reminder to us why Mary is so special in God’s plan of salvation.
