In consequence of this opinion, it was the first but arduous duty of a Christian to preserve himself pure and undefiled by the practice of idolatry. The religion of the nations was not merely a speculative doctrine professed in the schools or preached in the temples. The innumerable deities and rites of polytheism were closely interwoven with every circumstance of business or pleasure, of public or of private life; and it seemed impossible to escape the observance of them, without, at the same time, renouncing the commerce of mankind, and all the offices and amusements of society. The important transactions of peace and war were prepared or concluded by solemn sacrifices, in which the magistrate, the senator, and the soldier, were obliged to preside or to participate. The public spectacles were an essential part of the cheerful devotion of the Pagans, and the gods were supposed to accept, as the most grateful offering, the games that the prince and people celebrated in honor of their peculiar festivals. The Christians, who with pious horror avoided the abomination of the circus or the theatre, found himself encompassed with infernal snares in every convivial entertainment, as often as his friends, invoking the hospitable deities, poured out libations to each other's happiness. When the bride, struggling with well-affected reluctance, was forced into hymenæal pomp over the threshold of her new habitation, or when the sad procession of the dead slowly moved towards the funeral pile; the Christian, on these interesting occasions, was compelled to desert the persons who were the dearest to him, rather than contract the guilt inherent to those impious ceremonies. Every art and every trade that was in the least concerned in the framing or adorning of idols was polluted by the stain of idolatry; a severe sentence, since it devoted to eternal misery the far greater part of the community, which is employed in the exercise of liberal or mechanic professions. If we cast our eyes over the numerous remains of antiquity, we shall perceive, that besides the immediate representations of the gods, and the holy instruments of their worship, the elegant forms and agreeable fictions consecrated by the imagination of the Greeks, were introduced as the richest ornaments of the houses, the dress, and the furniture of the Pagan. Even the arts of music and painting, of eloquence and poetry, flowed from the same impure origin. In the style of the fathers, Apollo and the Muses were the organs of the infernal spirit; Homer and Virgil were the most eminent of his servants; and the beautiful mythology which pervades and animates the compositions of their genius, is destined to celebrate the glory of the dæmons. Even the common language of Greece and Rome abounded with familiar but impious expressions, which the imprudent Christian might too carelessly utter, or too patiently hear.
The dangerous temptations which on every side lurked in ambush to surprise the unguarded believer, assailed him with redoubled violence on the days of solemn festivals. So artfully were they framed and disposed throughout the year, that superstition always wore the appearance of pleasure, and often of virtue. Some of the most sacred festivals in the Roman ritual were destined to salute the new calends of January with vows of public and private felicity; to indulge the pious remembrance of the dead and living; to ascertain the inviolable bounds of property; to hail, on the return of spring, the genial powers of fecundity; to perpetuate the two memorable areas of Rome, the foundation of the city and that of the republic, and to restore, during the humane license of the Saturnalia, the primitive equality of mankind. Some idea may be conceived of the abhorrence of the Christians for such impious ceremonies, by the scrupulous delicacy which they displayed on a much less alarming occasion. On days of general festivity, it was the custom of the ancients to adorn their doors with lamps and with branches of laurel, and to crown their heads with a garland of flowers. This innocent and elegant practice might perhaps have been tolerated as a mere civil institution. But it most unluckily happened that the doors were under the protection of the household gods, that the laurel was sacred to the lover of Daphne, and that garlands of flowers, though frequently worn as a symbol of joy or mourning, had been dedicated in their first origin to the service of superstition. The trembling Christians, who were persuaded in this instance to comply with the fashion of their country, and the commands of the magistrate, labored under the most gloomy apprehensions, from the reproaches of his own conscience, the censures of the church, and the denunciations of divine vengeance.
Such was the anxious diligence which was required to guard the chastity of the gospel from the infectious breath of idolatry. The superstitious observances of public or private rites were carelessly practised, from education and habit, by the followers of the established religion. But as often as they occurred, they afforded the Christians an opportunity of declaring and confirming their zealous opposition. By these frequent protestations their attachment to the faith was continually fortified; and in proportion to the increase of zeal, they combated with the more ardor and success in the holy war, which they had undertaken against the empire of the demons.
Since therefore the most sublime efforts of philosophy can extend no further than feebly to point out the desire, the hope, or, at most, the probability, of a future state, there is nothing, except a divine revelation, that can ascertain the existence, and describe the condition, of the invisible country which is destined to receive the souls of men after their separation from the body. But we may perceive several defects inherent to the popular religions of Greece and Rome, which rendered them very unequal to so arduous a task. 1. The general system of their mythology was unsupported by any solid proofs; and the wisest among the Pagans had already disclaimed its usurped authority. 2. The description of the infernal regions had been abandoned to the fancy of painters and of poets, who peopled them with so many phantoms and monsters, who dispensed their rewards and punishments with so little equity, that a solemn truth, the most congenial to the human heart, was opposed and disgraced by the absurd mixture of the wildest fictions. 3. The doctrine of a future state was scarcely considered among the devout polytheists of Greece and Rome as a fundamental article of faith. The providence of the gods, as it related to public communities rather than to private individuals, was principally displayed on the visible theatre of the present world. The petitions which were offered on the altars of Jupiter or Apollo, expressed the anxiety of their worshippers for temporal happiness, and their ignorance or indifference concerning a future life. The important truth of the of the immortality of the soul was inculcated with more diligence, as well as success, in India, in Assyria, in Egypt, and in Gaul; and since we cannot attribute such a difference to the superior knowledge of the barbarians, we must ascribe it to the influence of an established priesthood, which employed the motives of virtue as the instrument of ambition.
We might naturally expect that a principle so essential to religion, would have been revealed in the clearest terms to the chosen people of Palestine, and that it might safely have been intrusted to the hereditary priesthood of Aaron. It is incumbent on us to adore the mysterious dispensations of Providence, when we discover that the doctrine of the immortality of the soul is omitted in the law of Moses it is darkly insinuated by the prophets; and during the long period which clasped between the Egyptian and the Babylonian servitudes, the hopes as well as fears of the Jews appear to have been confined within the narrow compass of the present life. After Cyrus had permitted the exiled nation to return into the promised land, and after Ezra had restored the ancient records of their religion, two celebrated sects, the Sadducees and the Pharisees, insensibly arose at Jerusalem. The former, selected from the more opulent and distinguished ranks of society, were strictly attached to the literal sense of the Mosaic law, and they piously rejected the immortality of the soul, as an opinion that received no countenance from the divine book, which they revered as the only rule of their faith. To the authority of Scripture the Pharisees added that of tradition, and they accepted, under the name of traditions, several speculative tenets from the philosophy or religion of the eastern nations. The doctrines of fate or predestination, of angels and spirits, and of a future state of rewards and punishments, were in the number of these new articles of belief; and as the Pharisees, by the austerity of their manners, had drawn into their party the body of the Jewish people, the immortality of the soul became the prevailing sentiment of the synagogue, under the reign of the Asmonæan princes and pontiffs. The temper of the Jews was incapable of contenting itself with such a cold and languid assent as might satisfy the mind of a Polytheist; and as soon as they admitted the idea of a future state, they embraced it with the zeal which has always formed the characteristic of the nation. Their zeal, however, added nothing to its evidence, or even probability: and it was still necessary that the doctrine of life and immortality, which had been dictated by nature, approved by reason, and received by superstition, should obtain the sanction of divine truth from the authority and example of Christ.
When the promise of eternal happiness was proposed to mankind on condition of adopting the faith, and of observing the precepts, of the gospel, it is no wonder that so advantageous an offer should have been accepted by great numbers of every religion, of every rank, and of every province in the Roman empire. The ancient Christians were animated by a contempt for their present existence, and by a just confidence of immortality, of which the doubtful and imperfect faith of modern ages cannot give us any adequate notion. In the primitive church, the influence of truth was very powerfully strengthened by an opinion, which, however it may deserve respect for its usefulness and antiquity, has not been found agreeable to experience. It was universally believed, that the end of the world, and the kingdom of heaven, were at hand. * The near approach of this wonderful event had been predicted by the apostles; the tradition of it was preserved by their earliest disciples, and those who understood in their literal senses the discourse of Christ himself, were obliged to expect the second and glorious coming of the Son of Man in the clouds, before that generation was totally extinguished, which had beheld his humble condition upon earth, and which might still be witness of the calamities of the Jews under Vespasian or Hadrian. The revolution of seventeen centuries has instructed us not to press too closely the mysterious language of prophecy and revelation; but as long as, for wise purposes, this error was permitted to subsist in the church, it was productive of the most salutary effects on the faith and practice of Christians, who lived in the awful expectation of that moment, when the globe itself, and all the various race of mankind, should tremble at the appearance of their divine Judge.
