Where does ultimate authority lie?
There is a science in theology and in biblical studies that we call hermeneutics. It is the science of biblical interpretation. It teaches objective principles and rules that govern our treatment of the text, lest we turn the Bible into a piece of clay that we can shape and form for our own desires, as the Pharisees did. At the heart of the science of hermeneutics in Reformed theology is the regula fidei, or “the law of faith,” which says that no portion of Scripture must ever be set against another portion of Scripture. The first assumption here is that all of Scripture is the Word of God . The second assumption is that God does not speak with a forked tongue , that what He reveals in His Word is always consistent. It is sometimes said consistency is the hobgoblin of little minds. If that adage is true, we have to say that the tiniest mind to be found is the mind of God. However, I believe consistency is the sign of clarity of truth, and God’s Word is consistent with it
