In the earlier days of Rome religion was looked upon as a function of the State; its chief object was to make the gods auspicious to the national policy,[748] and its principal ceremonies were performed at the direct command of the Senate. The national theory on religious matters was that the best religion [pg 399] is always that of a man's own country. At the same time, the widest tolerance was granted to the religions of conquered nations. The temples of every god were respected by the Roman army. Before besieging a city, the Romans were accustomed to supplicate the presiding deities of that city. With the single exception of the Druids, whose human sacrifices it was thought a matter of humanity to suppress,[749] and whose fierce rebellions it was thought necessary to crush, the teachers of all national religions continued unmolested by the conqueror.

This policy, however, applied specially to religious rites practised in the countries in which they were indigenous. The liberty to be granted to the vast confluence of strangers attracted to Italy during the Empire was another question. In the old Republican days, when the censors regulated with the most despotic authority the minutest affairs of life, and when the national religion was interwoven with every detail of political and even domestic transactions, but little liberty could be expected. When Carneades endeavoured to inculcate his universal scepticism upon the Romans, by arguing alternately for and against the same proposition, Cato immediately urged the Senate to expel him from the city, lest the people should be corrupted by his teaching.[750] For a similar reason all rhetoricians had been banished from the Republic.[751] The most remarkable, however, and at the same time the extreme expression of Roman intolerance that has descended to us, is the advice which Mæcenas is represented as having given to Octavius Cæsar, before his accession to the throne. “Always,” he said, “and everywhere, worship the gods according to the rites of your country, and compel others to the same worship. Pursue with your hatred and with punishments [pg 400] those who introduce foreign religions, not only for the sake of the gods—the despisers of whom can assuredly never do anything great—but also because they who introduce new divinities entice many to use foreign laws. Hence arise conspiracies, societies, and assemblies, things very unsuited to an homogeneous empire. Tolerate no despiser of the gods, and no religious juggler. Divination is necessary, and therefore let the aruspices and augurs by all means be sustained, and let those who will, consult them; but the magicians must be utterly prohibited, who, though they sometimes tell the truth, more frequently, by false promises, urge men on to conspiracies.”[752]

This striking passage exhibits very clearly the extent to which in some minds the intolerant spirit was carried in antiquity, and also the blending motives that produced it. We should be, however, widely mistaken if we regarded it as a picture of the actual religious policy of the Empire. In order to realise this, it will be necessary to notice separately liberty of speculation and liberty of worship.

When Asinius Pollio founded the first public library in Rome, he placed it in the Temple of Liberty. The lesson which was thus taught to the literary classes was never forgotten. It is probable that in no other period of the history of the world was speculative freedom so perfect as in the Roman Empire. The fearless scrutiny of all notions of popular belief, displayed in the writings of Cicero, Seneca, Lucretius, or Lucian, did not excite an effort of repression. Philosophers were, indeed, persecuted by Domitian and Vespasian for their ardent opposition to the despotism of the throne,[753] but on their own subjects they were wholly untrammelled. [pg 401] The Greek writers consoled themselves for the extinction of the independence of their country by the reflection that in the sphere of intellect the meddling policy of the Greek States was replaced by an absolute and a majestic freedom.[754] The fierceness of the opposition of sects faded beneath its influence. Of all the speculative conflicts of antiquity, that which most nearly approached the virulence of later theological controversies was probably that between the Stoics and the Epicureans; but it is well worthy of notice that some of the most emphatic testimonies to the moral goodness of Epicurus have come from the writings of his opponents.

But the policy of the Roman rulers towards religious rites was very different from, and would at first sight appear to be in direct opposition to, their policy towards opinions. An old law, which Cicero mentions, expressly forbade the introduction of new religions,[755] and in the Republican days and the earliest days of the Empire there are many instances of its being enforced. Thus, in a.u.c. 326, a severe drought having led men to seek help from new gods, the Senate charged the ædiles to allow none but Roman deities to be worshipped.[756] Lutatius, soon after the first Punic war, was forbidden by the Senate to consult foreign gods, “because,” said the historian, “it was deemed right the Republic should be administered according to the national auspices, and not according to those of other lands.”[757] During the second Punic war, a severe edict of the Senate enjoined the suppression of certain recent innovations.[758] About a.u.c. 615 the prætor Hispalus exiled those who had introduced the worship of the Sabasian Jupiter.[759] The rites of Bacchus, being accompanied by gross and scandalous obscenity, were suppressed, [pg 402] the consul, in a remarkable speech, calling upon the people to revive the religious policy of their ancestors.[760] The worship of Isis and Serapis only gained its footing after a long struggle, and no small amount of persecution. The gross immorality it sometimes favoured, its wild and abject superstition, so thoroughly alien to the whole character of Roman life and tradition, and also the organisation of its priesthood, rendered it peculiarly obnoxious to the Government. When the first edict of suppression was issued, the people hesitated to destroy a temple which seemed so venerable in their eyes, and the consul Æmilius Paulus dispelled their fears by seizing an axe and striking the first blow himself.[761] During the latter days of the Republic, edicts had commanded the destruction of the Egyptian temples. Octavius, however, in his younger days, favoured the new worship, but, soon after, it was again suppressed.[762] Under Tiberius it had once more crept in; but the priests of Isis having enabled a patrician named Mundus to disguise himself as the god Anubis, and win the favours of a devout worshipper, the temple, by order of the emperor, was destroyed, the images were thrown into the Tiber, the priests were crucified, and the seducer was banished.[763] Under the same emperor four thousand persons were exiled to Sardinia, as affected with Jewish and Egyptian superstitions. They were commissioned to repress robbers; but it was at the same time [pg 403] added, with a characteristic scorn, that if they died through the unhealthiness of the climate, it would be but a “small loss.”[764]

These measures represent together a considerable amount of religious repression, but they were produced exclusively by notions of policy or discipline. They grew out of that intense national spirit which sacrificed every other interest to the State, and resisted every form of innovation, whether secular or religious, that could impair the unity of the national type, and dissolve the discipline which the predominance of the military spirit and the stern government of the Republic had formed. They were also, in some cases, the result of moral scandals. When, however, it became evident that the internal condition of the Republic was unsuited for the Empire, the rulers frankly acquiesced in the change, and from the time of Tiberius, with the single exception of the Christians, perfect liberty of worship seems to have been granted to the professors of all religions in Rome.[765] The old law upon the subject was not revoked, but it was not generally enforced. Sometimes the new creeds were expressly authorised. Sometimes they were tacitly permitted. With a single exception, all the religions of the world raised their heads unmolested in the “Holy City.”[766]

The liberty, however, of professing and practising a foreign worship did not dispense the Roman from the obligation of performing also the sacrifices or other religious rites of his own land. It was here that whatever religious fanaticism mingled with Pagan persecutions was displayed. Eusebius tells us that religion was divided by the Romans [pg 404] into three parts—the mythology, or legends that had descended from the poets; the interpretations or theories by which the philosophers endeavoured to rationalise, filter, or explain away these legends; and the ritual or official religious observances. In the first two spheres perfect liberty was accorded, but the ritual was placed under the control of the Government, and was made a matter of compulsion.[767] In order to realise the strength of the feeling that supported it, we must remember that the multitude firmly believed that the prosperity and adversity of the Empire depended chiefly upon the zeal or indifference that was shown in conciliating the national divinities, and also that the philosophers, as I have noticed in the last chapter, for the most part not only practised, but warmly defended, the official observances. The love of truth in many forms was exhibited among the Pagan philosophers to a degree which has never been surpassed; but there was one form in which it was absolutely unknown. The belief that it is wrong for a man in religious matters to act a lie, to sanction by his presence and by his example what he regards as baseless superstitions, had no place in the ethics of antiquity. The religious flexibility which polytheism had originally generated, the strong political feeling that pervaded all classes, and also the manifest impossibility of making philosophy the creed of the ignorant, had rendered nearly universal among philosophers a state of feeling which is often exhibited, but rarely openly professed, among ourselves.[768] The religious opinions of men had but [pg 405] little influence on their religious practices, and the sceptic considered it not merely lawful, but a duty, to attend the observances of his country. No one did more to scatter the ancient superstitions than Cicero, who was himself an augur, and who strongly asserted the duty of complying with the national rites.[769] Seneca, having recounted in the most derisive terms the absurdities of the popular worship, concludes his enumeration by declaring that “the sage will observe all these things, not as pleasing to the Divinities, but as commanded by the law,” and that he should remember “that his worship is due to custom, not to belief.”[770] Epictetus, whose austere creed rises to the purest monotheism, teaches as a fundamental religious maxim that every man in his devotions should “conform to the customs of his country.”[771] The Jews and Christians, who alone refused to do so, were the representatives of a moral principle that was unknown to the Pagan world.

It should be remembered, too, that the Oriental custom of deifying emperors having been introduced into Rome, to burn incense before their statues had become a kind of test of loyalty. This adoration does not, it is true, appear to have implied any particular article of belief, and it was probably regarded by most men as we regard the application of the term “Sacred Majesty” to a sovereign, and the custom of kneeling in his presence; but it was esteemed inconsistent with Christianity, and the conscientious refusal of the Christians to comply with it aroused a feeling resembling that which was long produced in Christendom by the refusal of Quakers to comply with the usages of courts.

The obligation to perform the sacred rites of an idolatrous worship, if rigidly enforced, would have amounted, in the case of the Jews and the Christians, to a complete proscription. It does not, however, appear that the Jews were ever persecuted on this ground. They formed a large and influential colony in Rome. They retained undiminished, in the midst of the Pagan population, their exclusive habits, refusing not merely all religious communion, but most social intercourse with the idolaters, occupying a separate quarter of the city, and sedulously practising their distinctive rites. Tiberius, as we have seen, appears to have involved them in his proscription of Egyptian superstitions; but they were usually perfectly unmolested, or were molested only when their riotous conduct had attracted the attention of the rulers. The Government was so far from compelling them to perform acts contrary to their religion, that Augustus expressly changed the day of the distribution of corn, in order that they might not be reduced to the alternative of forfeiting their share, or of breaking the Sabbath.[772]

It appears, then, that the old Republican intolerance had in the Empire been so modified as almost to have disappeared. The liberty of speculation and discussion was entirely unchecked. The liberty of practising foreign religious rites, though ostensibly limited by the law against unauthorised religions, was after Tiberius equally secure. The liberty of abstaining from the official national rites, though more precarious, was fully conceded to the Jews, whose jealousy of idolatry was in no degree inferior to that of the Christians. It remains, then, to examine what were the causes of the very exceptional fanaticism and animosity that were directed against the latter.
