Baptists are a Protestant tradition of Christianity distinguished by baptizing only believers (believer's baptism) and doing so by total immersion. Modern Baptist churches generally subscribe to the doctrines of soul competency (the responsibility and accountability of every person before God), sola fide (justification by faith alone), sola scriptura (the Bible as the sole infallible authority) and congregationalist ecclesiastical polity. Baptists generally recognize at least two sacraments or ordinances: Baptism and the Lord's Supper.
