Diocesan History and Information

The Diocese of New Jersey was founded in 1785, and is the second oldest diocese in the Episcopal Church, after the Diocese of Connecticut.

We elected our first bishop in 1815, the Right Reverend John Croes, who had been rector of Christ Church in New Brunswick prior to his election.

New Jersey ranks sixth out of 100 domestic dioceses in the Episcopal Church in the number of parishes. The diocese is 11th in number of baptized persons and the 9th largest by Average Sunday Attendance (2021).  It is also the largest diocese to be led by a woman. The diocese originally covered the entire state; due to the growth of the church in the mid-1800s, the northern third was split off in 1874 to become the Diocese of Northern New Jersey, known today as the Diocese of Newark. The dividing line is the border between Essex and Union Counties, between Morris and Somerset Counties, and between Warren and Hunterdon Counties. The exception is the City of Summit, which was assigned to the Diocese of Newark, allegedly because of 19th-century train routes.

There are 134 congregations in this diocese, including seasonal, collegiate, and institutional chapels. The oldest congregation in the diocese is Saint Peter’s Church in Perth Amboy, where services began in 1685. The oldest extant church building is St. Mary’s in Burlington, built in 1703 and enlarged several times. There are more than 15 colonial-era parishes in this diocese.  The Diocese has a reputation for broad ethnic, liturgical and socio-economic diversity.

Currently there are two retired bishops and 370 priests and deacons in the diocese, along with 55 clergy “licensed to act.” The Right Reverend Sally J. French, our diocesan bishop, was elected in January 2023 and consecrated in June 2023. She is the thirteenth diocesan bishop of New Jersey, and the first person in the Anglican Communion whose ordinations as deacon, priest, and bishop were all by women.

More information about the history of the diocese can be found in our Archives.


The cathedral (the home parish and seat of a bishop) of the diocese has been Trinity Cathedral in Trenton since the 1930s. Unofficial cathedrals (known as pro-cathedrals) for earlier bishops have been Christ Church, New Brunswick; Saint Mary’s, Burlington; and Christ Church, Trenton. See the Trinity Cathedral website to learn more about the cathedral and the important work it does in the diocese and its own neighborhood.
