Murphy Hall is St. John's large fellowship hall which is used for church gatherings and social events, such as Thanksgiving dinners, rummage sales, jazzercise classes, and Boy Scout Troop functions. The hall is 72ft. by 72ft. and is able to seat 450 people.

This expansive hall is named for Louise and Alfred Murphy who gave thirty-five acres of land on Rapid Run Road to the church. St. John's sold this property to retire the new building debt.
