Diocletian had no sooner published his edicts against the Christians, than, as if he had been desirous of committing to other hands the work of persecution, he divested himself of the Imperial purple. The character and situation of his colleagues and successors sometimes urged them to enforce and sometimes inclined them to suspend, the execution of these rigorous laws; nor can we acquire a just and distinct idea of this important period of ecclesiastical history, unless we separately consider the state of Christianity, in the different parts of the empire, during the space of ten years, which elapsed between the first edicts of Diocletian and the final peace of the church.
The mild and humane temper of Constantius was averse to the oppression of any part of his subjects. The principal offices of his palace were exercised by Christians. He loved their persons, esteemed their fidelity, and entertained not any dislike to their religious principles. But as long as Constantius remained in the subordinate station of Caesar, it was not in his power openly to reject the edicts of Diocletian, or to disobey the commands of Maximian. His authority contributed, however, to alleviate the sufferings which he pitied and abhorred. He consented with reluctance to the ruin of the churches; but he ventured to protect the Christians themselves from the fury of the populace, and from the rigor of the laws. The provinces of Gaul (under which we may probably include those of Britain) were indebted for the singular tranquillity which they enjoyed, to the gentle interposition of their sovereign. 165 But Datianus, the president or governor of Spain, actuated either by zeal or policy, chose rather to execute the public edicts of the emperors, than to understand the secret intentions of Constantius; and it can scarcely be doubted, that his provincial administration was stained with the blood of a few martyrs. 166 The elevation of Constantius to the supreme and independent dignity of Augustus, gave a free scope to the exercise of his virtues, and the shortness of his reign did not prevent him from establishing a system of toleration, of which he left the precept and the example to his son Constantine. His fortunate son, from the first moment of his accession, declaring himself the protector of the church, at length deserved the appellation of the first emperor who publicly professed and established the Christian religion. The motives of his conversion, as they may variously be deduced from benevolence, from policy, from conviction, or from remorse, and the progress of the revolution, which, under his powerful influence and that of his sons, rendered Christianity the reigning religion of the Roman empire, will form a very interesting and important chapter in the present volume of this history. At present it may be sufficient to observe, that every victory of Constantine was productive of some relief or benefit to the church.
The provinces of Italy and Africa experienced a short but violent persecution. The rigorous edicts of Diocletian were strictly and cheerfully executed by his associate Maximian, who had long hated the Christians, and who delighted in acts of blood and violence. In the autumn of the first year of the persecution, the two emperors met at Rome to celebrate their triumph; several oppressive laws appear to have issued from their secret consultations, and the diligence of the magistrates was animated by the presence of their sovereigns. After Diocletian had divested himself of the purple, Italy and Africa were administered under the name of Severus, and were exposed, without defence, to the implacable resentment of his master Galerius. Among the martyrs of Rome, Adauctus deserves the notice of posterity. He was of a noble family in Italy, and had raised himself, through the successive honors of the palace, to the important office of treasurer of the private Jemesnes. Adauctus is the more remarkable for being the only person of rank and distinction who appears to have suffered death, during the whole course of this general persecution. 167
The revolt of Maxentius immediately restored peace to the churches of Italy and Africa; and the same tyrant who oppressed every other class of his subjects, showed himself just, humane, and even partial, towards the afflicted Christians. He depended on their gratitude and affection, and very naturally presumed, that the injuries which they had suffered, and the dangers which they still apprehended from his most inveterate enemy, would secure the fidelity of a party already considerable by their numbers and opulence. 168 Even the conduct of Maxentius towards the bishops of Rome and Carthage may be considered as the proof of his toleration, since it is probable that the most orthodox princes would adopt the same measures with regard to their established clergy. Marcellus, the former of these prelates, had thrown the capital into confusion, by the severe penance which he imposed on a great number of Christians, who, during the late persecution, had renounced or dissembled their religion. The rage of faction broke out in frequent and violent seditions; the blood of the faithful was shed by each other’s hands, and the exile of Marcellus, whose prudence seems to have been less eminent than his zeal, was found to be the only measure capable of restoring peace to the distracted church of Rome. 169 The behavior of Mensurius, bishop of Carthage, appears to have been still more reprehensible. A deacon of that city had published a libel against the emperor. The offender took refuge in the episcopal palace; and though it was somewhat early to advance any claims of ecclesiastical immunities, the bishop refused to deliver him up to the officers of justice. For this treasonable resistance, Mensurius was summoned to court, and instead of receiving a legal sentence of death or banishment, he was permitted, after a short examination, to return to his diocese. 170 Such was the happy condition of the Christian subjects of Maxentius, that whenever they were desirous of procuring for their own use any bodies of martyrs, they were obliged to purchase them from the most distant provinces of the East. A story is related of Aglae, a Roman lady, descended from a consular family, and possessed of so ample an estate, that it required the management of seventy-three stewards. Among these Boniface was the favorite of his mistress; and as Aglae mixed love with devotion, it is reported that he was admitted to share her bed. Her fortune enabled her to gratify the pious desire of obtaining some sacred relics from the East. She intrusted Boniface with a considerable sum of gold, and a large quantity of aromatics; and her lover, attended by twelve horsemen and three covered chariots, undertook a remote pilgrimage, as far as Tarsus in Cilicia. 171
The sanguinary temper of Galerius, the first and principal author of the persecution, was formidable to those Christians whom their misfortunes had placed within the limits of his dominions; and it may fairly be presumed that many persons of a middle rank, who were not confined by the chains either of wealth or of poverty, very frequently deserted their native country, and sought a refuge in the milder climate of the West. † As long as he commanded only the armies and provinces of Illyricum, he could with difficulty either find or make a considerable number of martyrs, in a warlike country, which had entertained the missionaries of the gospel with more coldness and reluctance than any other part of the empire. 172 But when Galerius had obtained the supreme power, and the government of the East, he indulged in their fullest extent his zeal and cruelty, not only in the provinces of Thrace and Asia, which acknowledged his immediate jurisdiction, but in those of Syria, Palestine, and Egypt, where Maximin gratified his own inclination, by yielding a rigorous obedience to the stern commands of his benefactor. 173 The frequent disappointments of his ambitious views, the experience of six years of persecution, and the salutary reflections which a lingering and painful distemper suggested to the mind of Galerius, at length convinced him that the most violent efforts of despotism are insufficient to extirpate a whole people,
