"Origins" of Christianity

Despite a well-stocked library about Jesus, the Bible, Christianity, etc., I have discovered something with this book: "The temptation of Christianity." To be clear, despite the "high-flying" of the subject, one, refers us to report Jerphagnon Christianity - Roman world and the other, Ferry, perfectly explains this break between Christianity and Greek philosophy. Modestly, I added a comment: I enjoyed the passages concerning the "doctrine of salvation" and the contribution of Christianity on this subject. But also, this very precise and detailed explanation of Greek mythology and the disruption caused by Christianity, faced with this conception of Greek mythology and philosophy. This book, in fact, opens us to a different view of Paul of Tarsus, the "first" theologian of Christianity, and allows us to understand a little, the gap has occurred between Jesus, Paul and Christianity .. .
