On December 8, Fr. John Zuhlsdorf celebrated Mass for the feast of the Immaculate Conception in the presence of a Greater Prelate, His Excellency Robert Morlino, Bishop of Madison, Wisconsin. There was a very good turnout, and the bishop preached about true mercy. In addition to the propers of the day, the music included:
- Missa secunda, Michael Haller (1840–1915)
- Magnificat octavi toni, Ciro Grassi (1868–1952)
- Ave Maria, Jacob Handl (1550–1591
