About St. Mary · Seneca, Missouri
St. Mary Parish is a small Roman Catholic parish in Seneca, Missouri, in Newton County in the far southwest corner of the Show-Me State. Founded as a mission in 1884 and established as a full parish in 1957, the community traces its roots to 1875, when James Francis McGannon — Seneca's first Catholic — emigrated from Canada to open a hardware store. Worship has been led, since 2022, by Rev. Charles 'Chaz' Dunn as pastor, with Rev. Rabinson Kulandai Samy, HGN, serving as parochial vicar; the pastor also shepherds St. Canera Parish in Neosho and the Nativity of Our Lord Mission in Noel. The parish is a member of the Diocese of Springfield–Cape Girardeau and operates St. Mary School (Pre-K through 8th grade) as a centerpiece of its faith-formation ministry.

Why belong here
St. Mary is a tight-knit rural Catholic community of around 75 families in the heart of Newton County, with a school (Pre-K through 8th grade) where religion is woven into daily life.

An active Parish Pastoral Council organizes parish-school religion (PSR), adult formation, youth formation, Knights of Columbus Lenten fish frys, Stations of the Cross, Mercy Monday community service, and the parish picnic — all signs of a parish that knows how to gather as a family.

History of St. Mary Parish
St. Mary traces its roots to 1875, when Seneca's first Catholic, James Francis McGannon, emigrated from Canada and opened a hardware business. The Brady, Powers, and Yust families soon followed, and by 1881 McGannon had arranged for priests from Pierce City and Sarcoxie to celebrate Mass in McGannon Hall above his store. In 1884 Bishop John Hogan of Kansas City formally created St. Mary as a mission of St. Canera Parish in Neosho, with Fr. James Wood serving for five years. Fr. Kault was appointed pastor in 1893 (commuting from Subiaco, Arkansas) and oversaw construction of the brick church still in use today; it was dedicated in 1894 on land donated by McGannon and built without debt. St. Mary became a full parish in 1957 when Fr. Clem Ilmberger became its first resident pastor. A new community hall replaced the old Fort Crowder barracks hall in 1988, and the church was renovated and rededicated by Bishop John Leibrecht on March 1, 1996.

Faith Formation & School
Faith formation is at the heart of St. Mary's identity and is built around three pillars: the parish school, the Parish School of Religion, and adult/youth formation. St. Mary School (school.stmarycp.org) serves Junior Pre-Kindergarten (age 3) through 8th grade, with religion integrated into the daily curriculum and the entire school community regularly attending the Eucharist. Mrs. Cathy Scolaro serves as Director of Faith Formation. The Parish School of Religion (PSR) meets Sunday after Mass throughout the school year for grades K–12; Adult Formation Class meets the same time and is organized through the parish's Adult Formation Committee.

Priscilla Poor serves as Administrative Assistant and OCIA Director for St. Mary. Classes are offered at St. Mary's as part of the parish's adult formation program, and the parish pastoral plan calls for continuing and promoting these classes as a key evangelization tool.

Parish Pastoral Council & Ministries
St. Mary is governed in part by an active Parish Pastoral Council that has organized itself into four standing committees: Youth Formation, Adult Formation, Outreach, and Liturgy/Prayer.

The Liturgy/Prayer Committee oversees worship and prayer life; Youth Formation coordinates PSR, youth Mass participation, and Mercy Monday service; Adult Formation runs ongoing classes and speakers; and Outreach organizes community evangelization, parish welcoming, and Mercy Monday projects. A separate St. Mary's School Board oversees the parish school.

Parish Life & Outreach

The Knights of Columbus council hosts a weekly Lenten Fish Fry each Friday in Lent, which has become both a parish fundraiser and a gathering point.
