Assumption of the Blessed Virgin Mary Catholic Church

About this church

Assumption of the Blessed Virgin Mary Catholic Church celebrates Saturday Vigil Mass at 5:00 p.m. and Sunday Masses at 8:00 and 10:00 a.m., noon, and 5:30 p.m. in O'Fallon. The Sunday evening gathering is associated with Life Teen but is open to everyone. Daily Mass is offered Monday through Friday at 6:30 and 8:00 a.m., plus Saturday at 8:00. Rosary begins thirty minutes before Sunday Masses, and Tuesday's Mother of Perpetual Help devotion begins at 6:15 p.m. Livestream and video archives support people unable to attend in person.

The parish organizes its mission around worship and prayer, formation and education, service and hospitality, and stewardship. A full-time school, Parish School of Religion, children's Liturgy of the Word, Vacation Bible School, EDGE middle-school ministry, and Life Teen provide distinct formation paths. The parish's stated aim is to find Christ within the community and bring Christ to the world through learning, worship, and service. For Catholic households in St. Charles County, the five weekend Mass choices, two weekday morning times, regular devotions, livestream, and age-specific formation make Assumption's weekly sacramental and educational life unusually easy to compare.
