Saturday, December 8, is the Feast of the Immaculate Conception and is a Holy Day of Obligation. Because the feast falls on a Saturday this year, there is an obligation to attend Mass twice; once for the Holy Day and once for the Second Sunday of Advent. Masses for the Immaculate Conception will be held at: Friday, December 7 at 5:30 p.m. (Vigil) and on Saturday, December 8 at 8:00 AM
