Ours is said to be a Godless age, yet billions remain faithful to religions thousands of years old. This provocative eight-part series explores the history and global impact of the world's biggest religion through the personal views of leading British figures. Over the course of the series, eight high-profile personalities—including Michael Portillo, Rageh Omaar, Kwame Kwei-Armah and Cherie Blair— look at the origins and history of the Christian faith. In each film the presenter addresses a subject that means something particular to them. In doing so, they bring their own perspectives to a challenging and comprehensive debate that explores Christianity's role in shaping the modern world.
