Founded in 1706, the church is known for its features, including stained glass, rich wood work and a cemetery. St. John’s Episcopal Church is known as one of the oldest Episcopal Churches in America. Members of the church’s congregation stem from different backgrounds and cultures. St. John’s Episcopal Church has a Sunday school and a full Spanish Mass/Eucharist service.
Jonathan Dayton, who lived at Boxwood Hall, is buried in an unmarked grave in this church's cemetery. Dayton had served as a lieutenant and paymaster in the Revolutionary War. In 1789, he was one of four signers of the United States Constitution for the state of New Jersey.
