The historical movement known as Pietism emphasized the response of faith and inward transformation as crucial aspects of conversion to Christ. Unfortunately, Pietism today is often equated with a "holier-than-thou" spiritual attitude, religious legalism, or withdrawal from involvement in society.
In this book Roger Olson and Christian Collins Winn argue that classical, historical Pietism is an influential stream in evangelical Christianity and that it must be recovered as a resource for evangelical renewal. They challenge misconceptions of Pietism by describing the origins, development, and main themes of the historical movement and the spiritual-theological ethos stemming from it. The book also explores Pietism's influence on contemporary Christian theologians and spiritual leaders such as Richard Foster and Stanley Grenz.
