Book excerpt: Prominent Reformation historian Timothy Wengert introduces the basic components of Martin Luther's theology of the Bible and examines Luther's contributions to present-day biblical interpretation. Wengert addresses key points of debate regarding Luther's approach to the Bible that have often been misunderstood, including biblical authority, the distinction between law and gospel, the theology of the cross, and biblical ethics. He argues that Luther, when rightly understood, offers much wisdom to Christians searching for fresh approaches to the interpretation of Scripture. This brief but comprehensive overview is filled with insights on Luther's theology and its significance for contemporary debates on the Bible, particularly the New Perspective on Paul.
