Why are Catholic and Protestant Bibles Different?
All scripture is inspired by God and is useful for teaching, for refutation, for correction, and for training in righteousness, so that one who belongs to God may be competent, equipped for every good work. - 2 Timothy 3:16-17
Both Catholics and Protestants believe that the Bible is the Word of God and is a foundation of Christian faith. However, Protestant bibles contain 66 books while Catholic bibles include 73. We have to go back in history to explain why.
