One of the major flashpoints in academic biblical studies in the past 125 years has centered on the authorship and dating of the book of Isaiah. Beginning in the late 1800s, some scholars suggested that this book may have been written by multiple people over a period of centuries, a view that contrasts with the traditional one that the entire book of Isaiah was written in the eighth century BC by the Judean prophet Isaiah ben Amoz. Because for many conservative scholars the latter position is the only one that respects the divine inspiration of the text, and because they also believe that this position is endorsed by Jesus in the New Testament, the differing conclusions of mainstream and conservative scholars regarding the authorship and dating of the book of Isaiah have long served to divide these groups.
Bind Up the Testimony--a collection of essays from a colloquium held at Wheaton College in 2013--brings together a variety of evangelical responses to this issue. Although a few of the essays arrive at conservative conclusions regarding the authorship and dating of the book of Isaiah, most of them attempt to chart new, more nuanced directions for thinking on this subject, and suggest that careful attention to the (complicated) compositional history of the book of Isaiah need not be a hindrance--and can, in fact, be a help--to Christians who understand the book of Isaiah as divinely inspired Scripture that has spoken to God's people throughout the ages and that continues to speak to them today.
