"I was and I am an ordinary theologian, who does not have the Word of God at his disposal, but, at best, a 'Doctrine of the Word of God,'" writes Karl Barth in the preface of Die christliche Dogmatik im Emtwurf. Properly appreciating the complex career of Barth's characterization of what Scripture is theologically can open up constructive lines of inquiry regarding his self-description as a theologian and reader of the Bible. By mining Barth's published and posthumous theological and exegetical writings and sermons, both well-known materials and understudied writings such as the significant "Das Schriftprinzip der reformierten Kirche" lecture, Alfred H. Yuen offers a unique reading of Barth's thoughts on the person and work of the biblical writers by mapping his theological career as a university student, a pastor, a writer, a young professor, and, above all, a "child of God" (CD I/1, 464-65).
