[I]n the years that followed the persecutions, Christianity came to see itself, with great pride, as a persecuted Church. Its greatest heroes were not those who did good deeds but those who died in the most painful way. If you were willing to die an excruciating end in the arena then, whatever your previous holiness or lack thereof, you went straight to heaven: martyrdom wiped out all sins on the point of death. As well as getting there faster, martyrs enjoyed preferential terms in paradise, getting to wear the much-desired martyr's crown. Tempting celestial terms were offered: it was said that the scripture promised 'multiplication, even to a hundred times, of brothers, children, parents, land and homes'. Precisely how this celestial sum had been calculated is not clear but the general principle was: those who died early, publicly and painfully would be best rewarded. In many of the martyr tales the driving force is less that the Romans want to kill - and more that the Christians want to die. Why wouldn't they? Paradoxically, martyrdom held considerable benefits for those willing to take it on. One was its egalitarian entry qualifications. As George Bernard Shaw acidly observed over a millennium later, martyrdom is the only way a man can become famous without ability. More than that, in a socially and sexually unequal era it was a way in which women and even slaves might shine. Unlike most positions of power in the highly socially stratified late Roman Empire, this was a glory that was open to all, regardless of rank, education, wealth or sex. The sociologist Rodney Stark has pointed out that - provided you believe in its promised rewards - martyrdom is a perfectly rational choice. A martyr could begin the day of their death as one of the lowliest people in the empire and end it as one of the most exalted in heaven. So tempting were these rewards that pious Christians born outside times of persecution were wont to express disappointment at being denied the opportunity of an agonizing death. When the later Emperor Julian pointedly avoided executing Christians in his reign, one Christian writer far from being grateful, sourly recorded that Julian had 'begrudged the honour of martyrdom to our combatants'.
