Immaculate Conception
Monday, December 8 is the Solemnity of the Immaculate Conception of the Blessed Virgin Mary. On this day, we celebrate the dogma of Mary’s immaculate conception—that is, the fact she was preserved by any stain of original sin—in the womb of her mother, Anne. This is the Patronal Feast of the United States of America and is a holyday of obligation for all Catholics.
Our Mass schedule is:
- 9:00am with OLC School Students attending (Upper Basilica)
- 11:00am (Upper Basilica)
- 7:00pm (Upper Basilica)
If none of these times work, please check local parishes for their Mass schedule.
