Paul Fromont (again!) usefully highlights a new book, which respectfully takes issue with John Howard Yoder’s reading of Constantine. This looks as though it is a critical contribution to the concept of “post-Christendom” and “post-Constantinianism” in current mission thinking for western churches. The book is Peter Leithart, Defending Constantine: The Twilight of an Empire and the Dawn of Christendom, published by IVP (USA) in 2010. It’s going on my read list.
