The Brookhaven Christian Church belongs to the denomination known as the Disciples of Christ, the oldest and largest Protestant denomination founded in the United States. Brookhaven was founded in 1948; today it has about 300 members. The church believes in the "priesthood of all believers," a theology that holds that "all Christ's followers bear his message of love to the world and are responsible for proclaiming it." Brookhaven is people driven, meaning that it is led by the entire church community and not solely by its ministers.
