First Church of Christ, Scientist
905 Prospect Avenue

The First Church of Christ, Scientist was founded in 1892 on Grove Street. It was built through the efforts of Shepard Stewart of South Plainfield. The Y.M.H.A. purchased the building in May 1909.  The church is currently located at 905 Prospect Avenue; it is the only independent Christian Science church in the United States.

First Methodist Episcopal Church
West Front Street near Madison Avenue

The first Methodist service was said to have happened at a prayer meeting held in the Guion residence around 1823.  In 1826, an unsuccessful attempt was made to erect a church on Barn Street (later known as Second Street), while services were held at John Briant’s carriage shop. The First M. E. Church was eventually erected in 1832 – a plain, unpainted wooden structure.  In 1847, a new brick building was constructed on the site.  The church was burned in an 1869 fire, but immediately rebuilt and enlarged.  In 1894, the parsonage was sold.  In 1954, the second fire badly damaged the church.  A new one was built on the Rosenbaum property at 621-641 East Front Street, and the new First Methodist Church was dedicated on November 3, 1963.
 
Grace Church, in North Plainfield, was organized in 1893 and Monroe Avenue Church in 1896.
