In unsteady political, societal and ecclesial times, what might a missional ecclesiology offer? Drawn from a consultation instigated by the Church of England's Faith and Order Commission, this book seeks to offer a generative conversation involving theologians and practitioners across three key themes - the church's worship as a gathered community, its witness as a scattered community, and its walk as a pilgrim community. So often the church speaks as if there was a binary division between 'being' and 'doing', yet the contributors to this book collectively demonstrate that the situation is more complex. Taken together, the chapters in this volume offer an important resource for all who want to deepen and widen their understanding of the church's academic engagement with contemporary ecclesiology.
