Originally published in 1940, this book contains the text of the Birkbeck Lectures for 1937–8. Smyth assesses the contributions that Cambridge cleric Charles Simeon made to the Evangelical Revival in Cambridge in the eighteenth century, and includes correspondence between Simeon and other evangelical thinkers of the day among his sources. This book will be of value to anyone with an interest in religion in Georgian England and the Evangelical Revival.
