For the last 50 years, one of the most important discussions in global evangelicalism has concerned the idea of holistic mission, which proposes the integration of verbal evangelism and social engagement within Christian mission. This book examines how key terms such as "evangelism" and "mission" have been understood in contemporary evangelical declarations from 1966 to 2011, in the Bible, and in the missiological debate. It adopts an in-depth approach to the historical, biblical and theological analysis. The main thesis is that the different conceptions of evangelism and mission in general, and that of holistic mission in particular, have their root in the worldview of the various theologians and Christian leaders preparing these statements. The book evaluates the missiological conceptions of evangelism and mission proposed in the various declarations in the light of the Bible, so as to derive a biblical understanding of evangelism and mission.
