When Catholics and Protestants have discussions about what divides us, Protestants often pepper their Catholic friends with the question, “Where is that in the Bible?” But seldom do they stop to apply the standard of sola scriptura to their own beliefs. If they did, they would find that some of them don’t come from the Bible at all but from a theological tradition they received from a parent or pastor.
