"Constantine – a hard-headed general whose attempts at preaching to his courtiers were at best stilted and most likely totally inept – was a rather unlikely figure to have launched Christianity on its path, and his reasons for having suddenly cleaved so closely to the faith are still a matter of debate. For generations ordinary Romans continued to balance Christian beliefs with their old fondness for traditional gods and pagan rituals. Yet the power of Constantine’s decision in the early fourth century AD is undeniable. Before him, Christians were hounded, hated, and regarded as fodder for the wild beasts of the arena. After him, Christianity was propelled from an unpopular fringe cult to the central worship system in the empire. It was – perhaps appropriately – miraculous."
