The Feast of the Immaculate Conception is a Holy Day of Obligation. Masses to fulfill this obligation will be said on Friday night at 7:00 PM and Saturday morning at 8:00 AM.
These Mass times are correct in the bulletin published on December 2nd. However, there is a mistake on the Saturday morning Mass time on the monthly calendar insert in the bulletin from November 25th. The correct Mass time is 8:00 AM, NOT 9:00 AM. Sorry for the confusion!
