The book is a collection of essays, mostly by postgraduate researchers at the University of Birmingham and the Selly Oak Colleges under the supervision of Werner Ustorf, Professor of Mission. Authors from Africa, Asia, Europe and the Americas belonging to Protestant and Catholic churches share some of the theological and missiological issues with which they are engaged. Professor Robert Schreiter writes in his Foreword, They all seem to grasp the deeper import of mission, how it changes, even how it must change.
