It is not without a painful effort that, even after so many centuries, we can resign ourselves to be witnesses, in imagination only, of such a spectacle. We can scarce believe that amongst men of the same period and the same city so much ferocity could be displayed in opposition to so much courage, the passion for barbarity against the passion for virtue. Nevertheless, such is history; and it should be represented as it really was: first of all, for truth’s sake; then for the due appreciation of virtue and all it costs of effort and sacrifice; and, lastly, for the purpose of showing what obstacles have to be surmounted, what struggles endured, and what sufferings borne, when the question is the accomplishment of great moral and social reforms. Marcus Aurelius was, without any doubt, a virtuous ruler, and one who had it in his heart to be just and humane; but he was an absolute ruler, that is to say, one fed entirely on his owns ideas, very ill-informed about the facts on which he had to decide, and without a free public to warn him of the errors of his ideas or the practical results of his decrees. He ordered the persecution of the Christians without knowing what the Christians were, or what the persecution would be, and this conscientious philosopher let loose at Lyons, against the most conscientious of subjects, the zealous servility of his agents, and the atrocious passions of the mob. The persecution of the Christians did not stop at Lyons, or with Marcus Aurelius; it became, during the third century, the common practice of the emperors in all parts of the Empire: from A.D. 202 to 312, under the reigns of Septimius Severus, Maximinus the First, Decius, Valerian, Aurelian, Diocletian, Maximian, and Galerius, there are reckoned six great general persecutions, without counting others more circumscribed or less severe. The Emperors Alexander Severns, Philip the Arabian, and Constantius Chlorus were almost the only exceptions to this cruel system; and nearly always, wherever it was in force, the Pagan mob, in its brutality or fanatical superstition, added to imperial rigor its own atrocious and cynical excesses.
