Luther Discovers the Book

One of the great rediscoveries of the Reformation -especially of Martin Luther- was that the Word of God comes to us in a form of a Book. In other words Luther grasped this powerful fact: God preserves the experience of salvation and holiness from generation to generation by means of a Book of revelation, not a bishop in Rome, and not the ecstasies of Thomas Muenzer and the Zwickau prophets (see note 1). The Word of God comes to us in a Book. That rediscovery shaped Luther and the Reformation.

One of Luther's arch-opponents in the Roman Church, Sylvester Prierias, wrote in response to Luther's 95 theses: "He who does not accept the doctrine of the Church of Rome and pontiff of Rome as an infallible rule of faith, from which the Holy Scriptures, too, draw their strength and authority, is a heretic" (see note 2). In other words, the Church and the pope are the authoritative deposit of salvation and the Word of God; and the Book is derivative and secondary. "What is new in Luther," Heiko Oberman says, "is the notion of absolute obedience to the Scriptures against any authorities; be they popes or councils" (see note 3). In other words the saving, sanctifying, authoritative Word of God comes to us in a Book. The implications of this simple observation are tremendous.

In 1539, commenting on Psalm 119, Luther wrote, "In this psalm David always says that he will speak, think, talk, hear, read, day and night constantly—but about nothing else than God's Word and Commandments. For God wants to give you His Spirit only through the external Word" (see note 4). This phrase is extremely important. The "external Word" is the Book. And the saving, sanctifying, illuminating Spirit of God, he says, comes to us through this "external Word."

Luther calls it the "external Word" to emphasize that it is objective, fixed, outside ourselves, and therefore unchanging. It is a Book. Neither ecclesiastical hierarchy nor fanatical ecstasy can replace it or shape it. It is "external," like God. You can take or leave it. But you can't make it other than what it is. It is a book with fixed letters and words and sentences.
