But the official attitude of the permanent Roman Government is probably revealed in the famous correspondence between Pliny and his emperor, Trajan. Imperial Rome is not to set up an inquisition. No man is to be punished for his faith, but if he is accused to the governor and is obstinate in refusing to pay the obeisance demanded by the state he is to be punished for his contumacy. That is precisely the attitude which the most humane and enlightened Christian states have adopted towards heresy. Later, when the Faith grew in importance, and when it even reached the point of soldiers refusing the military oaths, occasional emperors, often the better emperors, strove to fight against it. Then there were sometimes inquisitions and wholesale martyrdoms as under Decius and Diocletian. But no martyrdom, however public or agonising, could quench the faith of those who saw the heavens opening and the Angels of God descending with their crowns of glory. The publicity of the scenes and the constancy of the victims increased, as usual, the number of the converts. Foolish magistrates sought to encounter obstinacy with further severity, and the Faith only grew the more abundantly. It was not so much his personal conversion--for that was tardy and half-hearted--as the motive of policy to secure an advantage over Maxentius, which induced Constantine to promulgate the Edict of Milan in 313, by which toleration was extended to the Christian faith throughout the Roman Empire. We must not be surprised that the best emperors, including the philosopher and saint, Marcus Aurelius, were the most bitterly hostile to Christianity. That is human nature. Stoic philosophers were teaching very much in common with Christian philosophy, but that renders it all the less likely that Stoic philosophers should be among the converts. Nevertheless Christian doctrine, especially in the Græco-Jewish communities of Asia Minor, was falling on prepared soil. The Stoic paradoxes had undoubtedly prepared the way for the Christian paradoxes. The doctrines of humility and asceticism were a commonplace of the Cynics. “No Cross, no Crown,” “He who would save his life must lose it”--such sayings as these would gain immediate assent from thoughtful Romans. Epictetus, a heathen slave of Domitian’s day, wrote his answer to the tyrant: “No man hath power over me. I have been set free by God. I know His Commandments; henceforth no man can lead me captive.” The Stoics were daily teaching that it is hard for a rich man to enter into the Kingdom of God. This is the creed of Marcus Aurelius: “To venerate the gods and bless them, and to do good to men, and to practise tolerance and self-restraint.” The horrors of the amphitheatre are one side of imperial society. But on the other side Musonius Rufus, a Stoic who stood high in the favour of Vespasian and Titus, went among the soldiers to preach against militarism. Slave-drivers as the Romans
