Mea culpa, mea culpa, mea maxima culpa: Fr. Nick misspoke at the Masses over the weekend. Saturday, December 8, the Solemnity of the Immaculate Conception of the Blessed Virgin Mary IS A HOLY DAY OF OBLIGATION. Therefore, Mass will be offered at 7:00 pm on Friday, December 7 and at 7:00 am on Saturday, December 8. He apologizes for his mistake.
