In general, Bible churches are committed to expository preaching, often by teaching verse-by-verse through an entire book of the Bible. This practice, fueled by the belief that the Bible is inerrant, inspired by God, and sufficient (born from the Protestant teachings of sola scriptura or prima scriptura), is central to the essence of most Bible churches, and is the origin of their name.
Bible churches almost universally hold to the doctrine of sola fide or justification by faith, a teaching born out of the Reformation.
