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."

The role of women? How should spiritual gifts operate? What is the church's mission?
