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.

Since the mid-twentieth century, the Church has allowed for Catholics to attend vigil, or anticipated, Masses for Sundays and Holy Days of Obligation as “a convenience for many of the faithful.”

“Most canon lawyers defer to Venerable Pope Pius XII’s Apostolic Constitution Christus Dominus (January 6, 1953), which gave 4:00 p.m. as the earliest time when anticipated Masses may be scheduled,” the bishops said in their 2017 letter.

This means that the Sunday obligation for Dec. 24 can be fulfilled on Sunday, or anytime after 4 p.m. on Dec. 23, and the Christmas Mass obligation can be fulfilled on Monday, anytime after 4 p.m. on Dec. 24.
