Why belong here
St. Sebastian is a mid-sized, family-oriented Catholic community of roughly 600 households with a personal touch — small enough to know your neighbors, big enough to support its own regional school and a full faith-formation program from pre-K through adult. Liturgy is clearly the heart of the parish: weekend Mass three times a week on the schedule, daily Mass and Eucharistic Adoration shared with partner parishes in Monessen and Perryopolis, Saturday confessions before the Vigil Mass, and a live-streamed Mass on YouTube for those who cannot attend in person. The parish also reaches beyond itself through its 'Journey of a Lifetime' mission — worshipping together and caring for the spiritual, emotional and physical needs of neighbors in the Belle Vernon area and beyond.
