The Southern Baptist Convention (SBC), alternatively the Great Commission Baptists (GCB), is a Christian denomination based in the United States. It is the world's largest Baptist organization, the largest Protestant, and the second-largest Christian body in the United States. The SBC is a cooperation of fully autonomous, independent churches with commonly held essential beliefs that pool some resources for missions.
Churches affiliated with the denomination are evangelical in doctrine and practice, emphasizing the significance of the individual conversion experience. This conversion is then affirmed by the person being completely immersed in water for a believer's baptism.
