Christians, Pagans, and the Altar of Victory, 384

You are a member of the Roman Senate in 384 AD. Constantine rescinded the old laws prohibiting Christianity, openly favored Christians in staffing the imperial bureaucracy, and established Constantinople as a specifically Christian city. Nevertheless, many Romans remain faithful to the traditional religion, which the Christians dismissively refer to as paganism. The result for much of the fourth century has been domestic turmoil.
