The editors present the history of Presbyterian global mission in the latter half of the twentieth century as a case study in the complex history of modern Protestant missions. The authors of the essays in section 1, “Historical Setting and Themes,” are qualified in terms of both their own research as well as their direct involvement in contemporary Presbyterian missions to narrate authoritatively what happened as well as to interpret the story thematically. The interpretative challenges are considerable: there are many approaches to and perspectives on the decline of mainline engagement in global mission, which ironically parallels the rapid growth and vitality of the so-called “younger churches” in the non–Western world. Especially noteworthy is the editors' use of extensive interviews with former (and now often retired) missionaries, whose insights on the denomination's mission strategies reveal the complexity and pathos of the rapid changes which have accompanied the globalization of the Christian movement. The “regional histories” in section 2 are written by highly qualified experts on each major area of the global Christian map. Since Presbyterian partnership with sister churches in all of these regions is an ongoing denominational commitment, these regional essays provide instant orientation in what is actually happening now and where the trajectories of development might lead. The contributors to this volume are truly the experts who can and do flesh out this story, making this book an invaluable resource not only for the student of world mission in general but for the Presbyterian who wants to understand the current situation, how it has come to be, and what might be the possible next steps. The book's eminent usefulness is enhanced by a detailed chronology of Presbyterian mission history from 1945 on, a comprehensive bibliography, and a detailed index.
