Over the past century, Christianity's place and role in the world have changed dramatically. In 1900, 80 percent of the world's Christians lived in Europe and North America. Today, more than 60 percent of the world's Christians live outside of that region. This change calls for a reexamination of the way the story of Christianity is told, the methodological tools for its analysis, and its modes of expression. Perhaps most significant is the role of Africa as the new Christian heartland. The questions and answers about Christianity and its contemporary mission now being developed in the African churches will have enormous influence in the years to come. This volume offers nine new essays addressing this sea-change and its importance for the future of Christianity.
