We welcome new members to our parish community with open arms! St. John XXIII Parish is located in the Winchester area of West Seneca, New York. Begun in 1928, the parish is a close-knit community based church and is the spiritual home of over 1200 families. All are welcome to join us for weekend Masses, or as a permanent member. When you come to worship with us, please introduce yourself to Fr. John, our pastor. 


The St. John XXIII family is an active community and values the participation of all of its members. In addition to liturgical ministries such as lectoring, serving as a Eucharistic Minister or an altar server, there are several activities to enrich the social and spiritual lives of parishioners. Your time, talent and treasure are valuable gifts in building the Kingdom of God at St. John XXIIII.
