Why belong here
St. Mary is a multi-generational Catholic parish with a long history in Mt. Morris (dating to 1870) and a simple, welcoming rhythm of life: Saturday Vigil Mass, two Sunday morning Masses with a community Rosary beforehand, weekday Masses, and weekly Confession. Parishioners describe themselves as a family that has prayed together for decades — many current members trace their family's presence at St. Mary back generations — and they gather in the St. Joseph Room for coffee and doughnuts after the 7:30 and 11:00 Sunday Masses. Visitors are invited to come for Mass, spend time with the Real Presence in the tabernacle, and connect through a variety of parish ministries.

History & Heritage
According to the Diocese of Lansing listing (and GCatholic's database entry), the parish traces its roots to 1870 in Mount Morris, Genesee County. The parish's own website preserves an oral tradition that the current church's stones were donated in the early 1900s by local farmers who hauled wagon loads in from their fields late at night. Many of the people at Mass today are members of long-time parish families — a point the parish highlights as part of its identity and welcome. In the Diocese of Lansing's 2022–2023 'Realign Resources for Mission' reorganization, St. Mary was grouped together with neighboring parishes in the Eastern Genesee Grouping of the Flint Deanery.
- Established 1870 (per GCatholic / Diocese of Lansing).
