This book consists of a revised version of my PhD thesis, completed at the University of St Andrews, Scotland, between September 2012 and June 2016, under the supervision of Professor N. T. Wright. After defending the thesis in October 2016, some minor revisions were made prior to its final completion in January 2017. Further revisions to prepare it for publication were undertaken after that point. However, none of this work has included consultation of any scholarship published since the end of 2016.
