Baptists firmly believe in sola Scriptura (Scripture alone). Properly understood, this is the concept of Scripture as a unified whole, utilizing literary critism called "historical Biblical scholarship," which was pioneered in the late 19th century, while rejecting the previous two millennia of commentaries by the [[Holy Fathers]].Orthodoxy, however, uses knows [[Holy Tradition]] to hold and interpret the [[Holy Scripture|Bible]]within itself. Like all Protestants, Baptists reject the [[deuterocanonical]] book books of the [[Old Testament]], considering them to be less than divinely inspired. Biblical inerrancy is yet another common heresy among fundamentalist Baptists. Furthermore, the individual Baptist is free to interpret the Bible for himself, usually using "historical Biblical scholarship," which was pioneered in the late 19th century, while rejecting the previous two millennia of commentaries by the [[Holy Fathers]].
