Embracing Shared Ministry: Power and Status in the Early Church and Why It Matters Today, Reviewed by Alexander Strauch: I highly commend this book. Hellerman shows how the biblical view of power and status was completely at odds with the Greco-Roman world. He then applies this to the book of Philippians, to Christ’s model, and ultimately to Christian leadership and church life. This is a perfect companion to my book Biblical Eldership.
The Prodigal Church: A Gentle Manifesto against the Status Quo. Bob Deffinbaugh's review: I would recommend Jared C. Wilson’s excellent book, which focuses on the megachurch model (which was Wilson’s background), but it is applicable to all churches. Wilson’s own experience of God’s grace helps him to be a very gracious critic of church life.
