From the earliest days of its history, persecution has unfailingly signalized the spread of Christianity, until to the thoughtful observer Christianity must afford the grimmest, the saddest—indeed, the most tragic—of all the paradoxes that go to make up the history of civilized man.

Its benign gospel of love has been thundered forth in malign hatred; its divine lesson of patience and forbearance has been taught in murderous impatience and bloodthirsty intolerance; its mild tenets of mercy and compassion have been ferociously expounded with fire and sword and rack; its precepts of humility have been inculcated with a pride and arrogance as harsh as any that the world has known.

It is impossible to deny that at almost any time in the history of Christianity the enlightened pagan of the second century would have been justified of his stinging gibe—“Behold how these Christians love one another!”

It may even be said of the earliest Christians that it was largely through their own intolerance of the opinions and beliefs of others that they brought upon themselves the persecutions to which through three centuries they were intermittently subjected. Certain it is that they were the first to disturb the toleration which in polytheistic Rome was accorded to all religions. They might have pursued their cult unmolested so long as they accorded the same liberty to others. But by the vehemence with which they denounced false all creeds but their own, they offended the zealous worshippers of other gods, and so disturbed the peace of the community; by denying obedience to the state in which they dwelt, by refusing to bear arms for the Empire on the plea of “Nolo militare; militia mea est ad Dominum!” they provoked the resentment of the law. When driven, by the beginnings of persecution, to assemble and celebrate their rites in secret, this very secrecy became the cause of further and sharper proceedings against them. Their mysteriousness evoked suspicion, and surmise sprang up to explain it. Very soon there was levelled against them the charge from which hardly any cult that celebrates in secret has been exempt. It was put abroad that they practised abominations, and that they engaged in the ritual murder of infants. Public opinion, ever credulous where evil is the subject, was still further inflamed against them, and fresh and greater disorders were the result. Thus they came to be denounced for atheism, insubordination, and subversion of public order.

The severity dealt out to them by a state hitherto indifferent—through the agnosticism prevalent in the ruling classes—to the religious opinions of its citizens, was dictated by the desire to suppress an element that had become socially perturbative, rather than by any vindictiveness or intolerance towards this new cult out of Syria.

Under Claudius we see the Nazarenes expelled from Rome as disturbers of the public peace; under Nero and Domitian we see them, denounced as hostes publici, suffering their first great persecution. But that persecution on purely religious grounds was repugnant to the Roman is shown by the conduct of Nerva, who forbade delations and oppressions on the score of belief, and recalled the Christians who had been banished. His successor, the just and wise Trajan, provoked perhaps by the fierce insurrection of the Jews which occurred in his reign, moved against the Nazarenes at first, but later on afforded them complete toleration. Similarly were they unmolested by the accomplished Adrian, who, indeed, so far approved of their creed as to have notions of including Christ in the Roman Pantheon; and they were left in peace by his successor Antoninus, notwithstanding that the last was so attached to the faith of his country and to the service of the gods as to have earned for himself the surname of Pius.

With the accession of the philosopher-emperor Marcus Aurelius, who was rendered hostile to the new doctrine not only by his own stoical convictions, but also because politically he viewed the Christians with disfavour, came the next great persecution; and persecution was their portion thereafter for some sixty years, under four reigns, until the accession of Alexander Severus in the third decade of the third century of the Christian era.

Alexander’s mother, Julia Mannea, is believed to have been instructed in the new doctrine by Origen, the Alexandrian, although her conversion to Christianity and her ideas upon it do not appear to be greatly in advance of those of Adrian, for she is said to have included an image of Christ in the group of beneficent deities set up in her lararium.[2]

For twenty years the Christians now knew peace and enjoyed the fullest liberty. Upon that followed a period of severe oppression, initiated by Decius, continued by Valerian and Aurelian, and reaching something of a climax under Diocletian, in the dawn of the fourth century, when the Christians endured the cruellest and most ferocious of all these persecutions. But the end of their sufferings was at hand, and with the accession of Constantine in 312 a new era began for Christianity. Constantine, upheld by the Christians as their saviour, in admitting the inevitable predominance which the new religion had obtained in rather less than three hundred years, was compelled to recognize the rights of its votaries not only to existence but to authority.

Legends surround the history of this emperor. The most popular relates how, when he was marching against Maxentius, his rival for the throne, desponding in the consciousness of his own inferior force, there appeared at sunset a fiery cross in the heavens with the inscription ΕΝ ΤΟΓΤΩ ΝΙΚΑ—IN THIS SIGN YOU CONQUER. And it is claimed that as a consequence of this portent, whose injunction he obeyed, he sought instruction in Christianity, was baptized and made public avowal of that faith. Others maintain that he was reared in Christianity by his mother, St. Helena—she who made an expedition to the Holy Land to recover the true cross, and who is said to have built the Church of the Holy Sepulchre in Jerusalem; whilst others still assert that Constantine did not receive baptism until at the point of death, and that throughout his life, whilst undoubtedly favouring Christians, he continued in the pagan religion in which he had been educated by his father.
