John Hosier has spent almost his entire working life leading local churches, particularly in the fast-growing Newfrontiers group of churches.

He explains, "In the second half of the twentieth century and into the twenty-first century there has grown up what have variously been referred to as House Churches, There has been a passion to get back to the kind of church life about which we read in the New Testament, while wanting to be absolutely relevant to the present age."

This book lays out the key convictions of many new churches about the Body of Christ: how it functions, and what it seeks to achieve. What is apostolic ministry? The nature of baptism? The role of women? How should spiritual gifts operate?
