The Episcopal Church in Westfield dates back to the spring of 1867. In the course of its development it has had three different names: Grace Church, Christ Church, and St. Paul's Church. It is one of the largest parishes in the Diocese of New Jersey with more than 1300 members.

The current building was constructed in 1952 with additional buildings added in 1960, including a chapel, 15 additional classrooms, a lounge, choir, office and staff rooms, cloister and garth.
