Recent decades have seen major shifts in our understanding of Christian identity. This timely book explores contemporary theological theory in asking what makes a Christian in the twenty-first century.

• Engages with developments in contemporary theological thought, assessing the work of leading figures Rowan Williams, John Milbank, and Kathryn Tanner
• Challenges accepted ideas of Christian identity by revealing largely unexplored perspectives on how sin affects its formation
• Contributes to vexed debates about Christian identity at a time when Christianity is expanding in some regions, yet in decline in many parts of the Western world
