" Many Romans didn’t like the Christians. They found their reclusive behaviour offensive; their teachings foolish; their fervour irritating and their refusal to sacrifice to the emperor insulting. But for the first 250 years after the birth of Christ, the imperial policy towards them was first to ignore them and then to declare that they must not be hounded. In the encounter between the Christians and the Romans it is the former who are almost without fail remembered as the oppressed and the latter as the oppressors. Yet, apart from Nero, it was almost two and a half centuries before emperors became involved in prosecutions of Christians – and even then, as we have seen, these prosecutions were brief. This was a grace and liberty that the Christians would decline to show to other religions when they finally gained control. A little over ten years after the newly Christian Constantine took power, it is said that laws began to be passed restricting ‘the pollutions of idolatry’. During Constantine’s own reign it seems to have been decreed that ‘no one should presume to set up cult-objects, or practise divination or other occult arts, or even to sacrifice at all’. Less than fifty years after Constantine, the death penalty was announced for any who dared to sacrifice. A little over a century later, in AD 423, the Christian government announced that any pagans who still survived were to be suppressed. Though, it added confidently – and ominously: ‘We now believe that there are none. "
