Students attend Mass once a week.
Students in grade 2 prepare for both the Sacrament of Reconciliation and Holy Eucharist in school as part of their Religion program and then receive these sacraments in their home parishes. Students in junior high prepare for Confirmation in school and are confirmed in their home parishes.
Each school day begins and ends with prayer and students attend Religion classes as a subject each day in the curriculum.
Stewardship is an important aspect of faith formation taught to students at Mother Teresa Catholic Academy. Students learn at an early age to give their time, talent, and treasure to help their school, their church, and their community. Homerooms engage in activities like making placemats and baking cookies for the parish Outreach meals for the needy; collecting toiletries for senior centers and nursing homes; collecting books, games and toiletries for a local veterans home, collecting blankets, food, and dog toys for a nearby animal hospital; and writing to soldiers overseas. During Advent and Lent. students participate in activities such as food drives, gift giving for Misericordia, and various projects that address world poverty and hunger such as Project Heifer, Operation Rice Bowl, Home of Hope in India, or South Suburban PADS here in Illinois.
All-school Masses will be held each Thursday and Holy Days.
