Missiologists and theologians do not often talk to each other, which has resulted in increased ignorance of each other's questions and concerns about how to do theology in ways that effectively serve the Church's mission. Under the auspices of the Tyndale Fellowship Christian Doctrine study group, a colloquium of distinguished scholars and practitioners recently gathered at the University of Cambridge. This volume, arising out of that symposium, begins conversations that have been waiting to happen. Each participant brings a particular perspective to questions about the nature of theology and how it is most meaningfully constructed so as to offer a truly interdisciplinary perspective on theology and mission. It highlights perspectives of contextual theology and systematic theology, as well as missiology and mission studies, world Christianity and historical inquiry, biblical studies and missional hermeneutics, ethnography, pastoral practice, and social justice. It also pays keen attention to matters on the ground with a profound desire to relate questions of evangelical identity - including ministry practice and mission - to the wider tradition.
