Propping up the wobbly throne with the might of Olympus was a stroke of brilliance that had nothing to do with arrogance or self-importance. In a world of chronic revolts, there was nothing like the threat of a little divine retribution to discourage rebellion. Now revolts were acts of impiety, and assassination was sacrilege. At a stroke, Diocletian had created an autocratic monarch, a semidivine emperor whose every command had the full force of religion backing it up. Though the faith behind it would change, this model of imperial power would be the defining political ideology of the Byzantine throne.
The pagans of the empire accepted it all willingly enough. They were pantheistic and could easily accommodate a divine emperor or two—they had in fact been deifying their dead rulers for centuries. Unfortunately for Diocletian, however, not all of his citizens were pagan, and his claims of divinity brought him into sharp conflict with the fastest-growing religion in the empire.
It wasn’t in the least bit surprising that Romans were abandoning the traditional gods. The recent reforms of Diocletian had undoubtedly made things somewhat easier, but for the vast majority of citizens, life was still on the whole miserably unjust. Oppressed by a heavy tax burden, made worse by the corruption of half a century of chaos, the common man found no protection in the tainted courts and had to watch helplessly as the rich expanded their lands at his expense. Crushed into hopelessness, more and more people took refuge in the different mystery cults, the most popular of which was Christianity.
Against the arbitrary injustice of the world all around them, Christianity held out hope that their suffering wasn’t in vain; that the seeming triumph of their grasping tormentors would be reversed by an all-powerful God who rewarded the just and punished the wicked. They weren’t alone in a dark and fallen world, but could be nourished by the hand of a loving God who sustained them with the promise of eternal life. This physical world with all its pain was only fleeting and would pass away to be replaced by a perfect one where sorrow was unknown and every tear was wiped away. The old pagan religion, with its vain, capricious gods and pale, shadowy afterlife, could offer nothing so attractive.
When the imperial officials showed up to demand a sacrifice to the emperor, most Christians flatly refused. They would gladly pay their taxes and serve in the army or on committees, but (as they would make abundantly clear) Christianity had room in it for only one God. No matter how powerful he might be, the emperor was just a man.
This rejection of Diocletian’s godhood struck at the very basis of imperial authority, and that was one thing the emperor wasn’t prepared to tolerate. These dangerous rebels—godless men who denied all divinity—had to be wiped out. An edict demanding sacrifice to the emperor on pain of death was proclaimed, and the Roman Empire launched its last serious attempt to suppress Christianity.
The effects were horrendous, especially in the east, where the edict was enforced with a terrible thoroughness. Churches were destroyed, Christian writings were burned, and thousands were imprisoned, tortured, or killed. But despite the fervor with which they were carried out, the persecutions couldn’t hope to be successful. Pagans and Christians had been more or less coexisting for years, and the suffering of the church was met with sympathy. There were the old stories, of course, the whispered tales of cannibalism and immorality, of Christians gathered in secret, eating their master’s flesh and drinking his blood, but nobody really believed them anymore. Most pagans refused to believe that a religion that encouraged payment of taxes, stable families, and honesty in trade could be full of dangerous dissidents, threatening the security of the state. Christians were neighbors and friends, common people like themselves, struggling as best they could to make it in a troubled world. Christianity in any case couldn’t be swept under the rug or persecuted out of existence. It had already spread throughout the empire and was well on its way to transforming the world.
Diocletian was fighting a losing battle against Christianity, and by AD 305 he knew it. A twenty-year reign had left him physically exhausted, and the glittering prestige of office no longer compensated enough. Nearing sixty and in declining health, the emperor had seen his youth slip away in service to the state and had no desire to spend what years remained under such a burden. Stunning his coemperors, he took a step unprecedented in Roman history, and announced his retirement. Typically of Diocletian, however, it was no mere abdication. It was, in its own way, as ambitious as anything he had ever attempted: a stunningly farsighted thrust to reverse the tide of history.
