took the Romans some time to distinguish between Christians and the other quarrelling segments of Judaism, but once Jews and Christians had separated, Christianity could not hope for any sort of official recognition. Normally the Roman authorities were tolerant of the religions in their conquered territories; as long as a religion had a tradition behind it, they could accept it as having some vague relationship to the official gods of Rome. All that they demanded was that subjects of the empire accept in turn some sort of allegiance to the official cult of the emperors, alive and dead.
