This book deals with the way Christianity took hold in the Roman world. Not, as some might think, after three centuries of persecution and then the conversion of a Roman Emperor.
Written by an archaeologist who has made the study of Roman times his life's work, Douglas Boin shows that Christianity expanded far more subtly until Christians found themselves in positions of authority. Many continued worshipping Roman Gods and Jesus Christ.
After Constantine it is often thought that the whole of The Roman Empire turned to Christ but that is equally untrue.
This book is short, scholarly and direct. It also describes New Testament letters attributed to Paul but not actually written by him (e.g. 2 Thessalonians) as fakes. I liked that. Sometimes it was an honour to take your master's name for a scholarly work, but not if you used his name for your own polemic.
And I like that my Bible contains this kind of thing.
