In a newsletter issued earlier this year, the U.S. Catholic bishops addressed questions regarding whether Sunday and Holy Day Mass obligations can be fulfilled with a "two-for-one" Mass attendance at Christmas this year.
In a "relatively rare" situation which last occurred in 2006, Christmas Day this year falls on a Monday.
Because Catholics are obliged to attend Mass for Sundays and Holy Days of Obligation, some have asked whether a Sunday evening Mass on Christmas Eve would fulfill both the obligation for a Sunday Mass and the obligation for a Christmas Day Mass.
The U.S. Bishop's Committee on Divine Worship has said the faithful should attend two Masses to fulfill their Sunday and Christmas Mass obligations.
