Book excerpt: Cathy Ross and Steve Bevans are two of the biggest names in the study of mission and missiology worldwide. Cathy is director of OxCEPT at Ripon College Cuddesdon and Steve Bevans is teaching missiology at the Catholic Theological Union in Chicago. The contributors in the book consider mission through the lens of ‘prophetic dialogue'. The book consciously tries to bring a fresh approach – introducing some newer themes (identity, creation, migration) and bringing a different perspective on some older themes by grouping them in this way. It is theological rather than issues-based and involves both older and newer contributors. The book is aimed at scholars and students of missiology in the UK, the US and worldwide. It is also a contribution to the study of world Christianity and contextual theology. Contributors include Jonny Baker, Kirsteen Kim, Gavin d'Costa, Emma Wild-Wood, Robert Schreiter and S. Mark Heim.
