The completion of a series of 35 books on mission and world Christianity was cause for celebration at the Oxford Centre for Mission Studies on Friday 4 September. The Regnum Edinburgh Centenary Series grew out of the Edinburgh 2010 project. Five years on, the series has become the most comprehensive and accessible study of contemporary Christianity. 80 mission thinkers joined the series editors to mark the close of a series that is remarkable for its global scope. It aims not only to be a scholarly resource but also to build mutual understanding among the churches. The 600 contributors are from all continents – with a special focus on Asia, Africa and Oceania – and all strands of Christianity – Catholic, Orthodox, Protestant, Evangelical, Pentecostal. Published by Regnum Books International in the UK and Wipf and Stock in the USA, the series is also made available in through a world library programme and through electronic download to encourage further study and collaboration in mission. Topics include Freedom of Belief; Global Diasporas; Mission at and from the Margins; Christian Communities in Global Societies; Ministry of Reconciliation; Authentic Discipleship; Christian Mission among Other Faiths;and Creation Care.
