The seven parts introduce the history of Christianity worldwide, period by period, up to the present day. 23 specially commissioned main chapters by expert historians from the framework within which 148 short features appear; on people, movements and subjects of special interest. 461 pictures, 218 of them in full colour, give the 'feel' of each period. 30 maps, diagrams and time charts help the reader to understand and interpret the story, giving a birds eye view of events. Colour coding of the different parts and a whole section of indexes make it easy to find the way and use the book for reference. The emphasis of the book is on growth and vitality rather that church institutions, giving a broad understanding of a whole period, then spotlighting the key Christian movements and outstanding personalities.
