Amidst the frequent revolutions of the empire, the Christians still flourished in peace and prosperity; and notwithstanding a celebrated aera of martyrs has been deduced from the accession of Diocletian, 131 the new system of policy, introduced and maintained by the wisdom of that prince, continued, during more than eighteen years, to breathe the mildest and most liberal spirit of religious toleration. The mind of Diocletian himself was less adapted indeed to speculative inquiries, than to the active labors of war and government. His prudence rendered him averse to any great innovation, and though his temper was not very susceptible of zeal or enthusiasm, he always maintained an habitual regard for the ancient deities of the empire. But the leisure of the two empresses, of his wife Prisca, and of Valeria, his daughter, permitted them to listen with more attention and respect to the truths of Christianity, which in every age has acknowledged its important obligations to female devotion. 132 The principal eunuchs, Lucian 133 and Dorotheus, Gorgonius and Andrew, who attended the person, possessed the favor, and governed the household of Diocletian, protected by their powerful influence the faith which they had embraced. Their example was imitated by many of the most considerable officers of the palace, who, in their respective stations, had the care of the Imperial ornaments, of the robes, of the furniture, of the jewels, and even of the private treasury; and, though it might sometimes be incumbent on them to accompany the emperor when he sacrificed in the temple, 134 they enjoyed, with their wives, their children, and their slaves, the free exercise of the Christian religion. Diocletian and his colleagues frequently conferred the most important offices on those persons who avowed their abhorrence for the worship of the gods, but who had displayed abilities proper for the service of the state. The bishops held an honorable rank in their respective provinces, and were treated with distinction and respect, not only by the people, but by the magistrates themselves. Almost in every city, the ancient churches were found insufficient to contain the increasing multitude of proselytes; and in their place more stately and capacious edifices were erected for the public worship of the faithful. The corruption of manners and principles, so forcibly lamented by Eusebius, 135 may be considered, not only as a consequence, but as a proof, of the liberty which the Christians enjoyed and abused under the reign of Diocletian. Prosperity had relaxed the nerves of discipline. Fraud, envy, and malice prevailed in every congregation. The presbyters aspired to the episcopal office, which every day became an object more worthy of their ambition. The bishops, who contended with each other for ecclesiastical preeminence, appeared by their conduct to claim a secular and tyrannical power in the church; and the lively faith which still distinguished the Christians from the Gentiles, was shown much less in their lives, than in their controversial writings.
Notwithstanding this seeming security, an attentive observer might discern some symptoms that threatened the church with a more violent persecution than any which she had yet endured. The zeal and rapid progress of the Christians awakened the Polytheists from their supine indifference in the cause of those deities, whom custom and education had taught them to revere. The mutual provocations of a religious war, which had already continued above two hundred years, exasperated the animosity of the contending parties. The Pagans were incensed at the rashness of a recent and obscure sect, which presumed to accuse their countrymen of error, and to devote their ancestors to eternal misery. The habits of justifying the popular mythology against the invectives of an implacable enemy, produced in their minds some sentiments of faith and reverence for a system which they had been accustomed to consider with the most careless levity. The supernatural powers assumed by the church inspired at the same time terror and emulation. The followers of the established religion intrenched themselves behind a similar fortification of prodigies; invented new modes of sacrifice, of expiation, and of initiation; 136 attempted to revive the credit of their expiring oracles; 137 and listened with eager credulity to every impostor, who flattered their prejudices by a tale of wonders. 138 Both parties seemed to acknowledge the truth of those miracles which were claimed by their adversaries; and while they were contented with ascribing them to the arts of magic, and to the power of daemons, they mutually concurred in restoring and establishing the reign of superstition. 139 Philosophy, her most dangerous enemy, was now converted into her most useful ally. The groves of the academy, the gardens of Epicurus, and even the portico of the Stoics, were almost deserted, as so many different schools of scepticism or impiety; 140 and many among the Romans were desirous that the writings of Cicero should be condemned and suppressed by the authority of the senate. 141 The prevailing sect of the new Platonicians judged it prudent to connect themselves with the priests, whom perhaps they despised, against the Christians, whom they had reason to fear. These fashionable Philosophers prosecuted the design of extracting allegorical wisdom from the fictions of the Greek poets; instituted mysterious rites of devotion for the use of their chosen disciples; recommended the worship of the ancient gods as the emblems or ministers of the Supreme Deity, and composed against the faith of the gospel many elaborate treatises, 142 which have since been committed to the flames by the prudence of orthodox emperors. 143
Although the policy of Diocletian and the humanity of Constantius inclined them to preserve inviolate the maxims of toleration, it was soon discovered that their two associates, Maximian and Galerius, entertained the most implacable aversion for the name and religion of the Christians. The minds of those princes had never been enlightened by science; education had never softened their temper. They owed their greatness to their swords, and in their most elevated fortune they still retained their superstitious prejudices of soldiers and peasants. In the general administration of the provinces they obeyed the laws which their benefactor had established; but they frequently found occasions of exercising within their camp and palaces a secret persecution,
