The Church of England, the Church of Scotland and the variety of Nonconformist denominations and sects in England, Scotland and Wales are discussed, but the book concentrates on the broad patterns of change affecting all the churches. It shows the great impact of the Evangelical movement on nineteenth-century Britain, accounts for its resurgence since the Second World War and argues that developments in the ideas and attitudes of the movement were shaped most by changes in British culture.

The contemporary interest in the phenomenon of Fundamentalism, especially in the United States, makes the book especially timely.
