I've long been facinated by the gradual movement of Christianity from a supposedly "persecuted" religious minority into the prime position of the "Official" religion of the Roman Empire...
Since the Roman Emperors ruled by means of the Imperial Roman Army, it is most significant that the message of "peace" that 'jesus' initially taught, was gradually morphed into one of warfare as the New Testament books were crafted.
And that the Roman Emperors eventually saw fit to make the 'enhanced' version of Christianity the "official" religion.
