Sola scriptura is the teaching that the Bible is the only inspired and authoritative word of God, is the only source for Christian doctrine, and is accessible to all — that is, it is perspicuous and self-interpreting.

All Scripture is inspired by God and profitable for teaching, for reproof, for correction, for training in righteousness; that the man of God may be adequate, equipped for every good work. (Psalm 119:18; Psalm 138:2; II Tim. 3:14-17)
