In 2005, Peter Enns published an important book on the topic of the Old Testament's authority.  I review it in Scottish Journal of Theology 62 (2009): 240-242.  Click here for an account of some the controversy that followed Enns' publication of this book.  (My review was submitted to SJT before Enns' suspension from Westminster Theological Seminary, which is why I don't mention it in the review.)
