Baptists are Christians distinguished by baptizing professing believers only, and doing so by complete immersion. Baptist churches also generally subscribe to the tenets of soul competency/liberty, salvation through faith alone, scripture alone as the rule of faith and practice, and the autonomy of the local congregation. Baptists generally recognize two ordinances: baptism and the Lord's supper. Baptist churches are widely considered to be Protestant, though some Baptists disavow this identity.
