Mass Schedule

Mass is celebrated Monday-Tuesday and Thursday-Friday on school days in our Chapel at 7:50 a.m. All are welcome to attend.

Adoration and Confession occur on select Fridays in our Chapel; check school calendar in OnCampus for most current schedule.

All-School Masses

Students, faculty, and staff attend all-school Masses several times during the school year on holy days of obligation and other special occasions such as the Mass of the Holy Spirit, a Jesuit tradition to begin a new school year, and the Missioning Mass that commissions juniors to their year-long service projects. The turf and the gymnasium are transformed into places of prayer for the all-school Masses. 

On days when an all-school Mass is scheduled (see calendar below), there is no daily Mass at 8 a.m. Parents who wish to attend an all-school Mass should check in through the main office. For 2021 we plan to celebrate all-school Mass on August 20, September 14, November 1, and December 8.

Class Masses

Students and faculty attend class Masses once each quarter to celebrate the Eucharist as a class. Masses are held in the Boian Chapel during the first class period of the day.

If you are interested in being involved in planning a liturgy, serving, or helping with music, please contact Director of Campus Ministry Kelsey Grimm at

Prayer Groups

Several prayer groups are offered at De Smet Jesuit. Some meet weekly, while other are for a more defined period of time like Advent & Lent. Please see descriptions below or go to the Campus Ministry Center for more information.
