Today’s biblical scholars and dogmaticians are giving a significant amount of attention to the topic of theological exegesis. A resource turned to for guidance and insight in this discussion is the history of interpretation, and Karl Barth’s voice registers loudly as a helpful model for engaging Scripture and its subject matter. Most readers of Barth’s theological exegesis encounter him on the level of his New Testament exegesis. This is understandable from several different vantage points. Unfortunately, Barth’s theological exegesis of the Old Testament has not received the attention it deserves. This book seeks to fill this lacuna as it encounters Barth’s theological exegesis of Isaiah in the Church Dogmatics. From the Church’s inception, Isaiah has been understood as Christian Scripture. In the Church Dogmatics we find Barth reading Isaiah in multi-functional and multi-layered ways as he seeks to hear Isaiah as a living witness to God’s triune revelation of himself in Jesus Christ.
