In 1993-1994, the Parish of St. Francis Xavier Church in Marcellus, New York celebrated its 140th anniversary as a religious community, and its 125th anniversary as a church. As Marcellus celebrated its bicentennial founding in 1794, the Roman Catholic community in Marcellus was also witness to a special celebration. On December 3, 1993, Rev. Peter M. Creed, Pastor of St. Francis Xavier Church, celebrated a special mass to commemorate the 125th anniversary of the church. And the church continued to join with the Marcellus community in commemorating the town's bicentennial throughout 1994.

The first Mass was celebrated by the Rev. Michael Haes (Hayes) who was somewhat of a circuit rider, covering not only Onondaga County, but parts of Madison, Cortland, and Oswego. Baptismal and marriage records in widely separated places bear his name, if not his signature.

As a religious community for over 140 years, St. Francis Xavier has grown from a membership of about 20 people to over 650 families at present. In that time period, there have been over 4000 baptisms performed at SFX, along with over 1000 marriages, and over 3000 interments have taken place in the parish cemetery. There have been eleven resident pastors and a number of assistant pastors at St. Francis Xavier Church
