Justin, by his self-denying devotion, soon became conspicuous in all the churches. He wrote an apology in behalf of the Christians. This treatise, which would do honor to any pen in the nineteenth century, was addressed “To the Emperor Antoninus, his two sons, the Roman senate, and all the Roman people.” Very lucidly he stated the essential doctrines of Christianity, and the nature of the evidence upon which the religion was founded. With resistless force of argument he refuted the calumnies with which the Christians were assailed, showing that their hopes of eternal happiness were all forfeited if they allowed themselves in any known sin. He dwelt upon the injustice of condemning Christians for their name alone. He made it perfectly clear to the humblest intelligence, that, when the Christians spoke of the kingdom of Christ, they had reference, not to an earthly, but to a spiritual kingdom. He stated the nature and design of the sacraments,――of baptism and the Lord’s supper. Justin closed his apology with the following forcible words:―― “If you find Christianity to be reasonable, respect it: but do not condemn to death, simply because they are Christians, those who have committed no crime; for we declare to you, that you cannot escape the judgment of God if you persist in such wickedness. As for us, we only say, ‘The will of God be done.’ We might demand justice of you in virtue of the decree of your illustrious father Adrian; but we have preferred to rest our cause upon the justice of our demands.” This admirable treatise, calmly written with great force of language and cogency of argument, must have exerted a very powerful influence. Still popular prejudice is seldom removed by argument. Though here and there many leading minds were led to regard Christianity with more favor, still the malice of the ignorant and brutal masses, who were ever crying, “To the lions with the Christians!” remained unchanged. Justin was at Rome when he wrote this apology. Soon after, he left Rome, and retired to Ephesus. Upon the death of Antoninus, whose reign of twenty-two years was an uneventful one, Marcus Aurelius ascended the throne. For some unexplained reason, the new emperor commenced his reign with very unfriendly feelings towards the Christians. Though he issued no decree of persecution, yet he afforded the disciples no protection: they were left to be maltreated by the brutal populace, and often to be condemned to torture and death by the angry and unprincipled governors of distant provinces. In the seventh year of the reign of Marcus Aurelius, a very terrible persecution of the Christians sprang up in Smyrna and its environs. The emperor remained silent in his palace while the Christians were scourged to death, burnt at the stake, or thrown to wild beasts. It is said that these martyrs were so wonderfully sustained by supernatural power, that, in their hours of most dreadful anguish, not a groan escaped their lips.
