IMMACULATE CONCEPTION December 8 is the feast of the Immaculate Conception and is one of the Holy Days of Obligation. Since it falls on a Sunday this year, the feast is transferred to December 9 but the obligation is lifted. Our Lady of Perpetual Help will celebrate Mass with the school on Monday, December 9 at 8:30 AM. Everyone is invited to attend. (this will take the place of the Wednesday school Mass for the week)
