But we all know that the religion of the Roman empire was falling into multitudinous confusion when Christianity arose—an austere exclusive faith, with its army of saints, ascetics, and unflinching martyrs, proclaiming worship to be due to one God only, and sternly refusing to acknowledge the divinity of the emperor. Against such a faith an incoherent disorderly polytheism could make no better stand than tribal levies against a disciplined army. The new religion struck directly at the sacrifices that symbolised imperial unity; the passive resistance of Christians was necessarily treated as rebellion, the State made implacable war upon them. Yet the spiritual and moral forces won the victory, and Christianity established itself throughout the empire. Universal religion, following upon universal civil dominion, completed the levelling of local and national distinctions. The Churches rapidly grew into authority superior to the State within their own jurisdiction; they called in the temporal government to enforce theological decisions and to put down heresies; they founded a powerful hierarchy. The earlier Roman constitution had made religion an instrument of administration. When one religion became universal, the churches enlisted the civil ruler into the service of orthodoxy; they converted the State into an instrument for enforcing religion. The pagan empire had issued edicts against Christianity and had suppressed Christian assemblies as tainted with disaffection; the Christian emperors enacted laws against the rites and worships of paganism, and closed temples. It was by the supreme authority of Constantine that, for the first time in the religious history of the world, uniformity of belief was defined by a creed, and sanctioned by the ruler's assent.
Then came, in Western Europe, the time when the empire at Rome was rent asunder by the inrush of barbarians; but upon its ruins was erected the great Catholic Church of the Papacy, which preserved in the ecclesiastical domain the autocratic imperial tradition. The primacy of the Roman Church, according to Harnack, is essentially the transference to her of Rome's central position in the religions of the heathen world; the Church united the western races, disunited politically, under the common denomination of Christianity. Yet Christianity had not long established itself throughout all the lands, in Europe and Asia, which had once been under the Roman sovereignty, when the violent irruptions of Islam upset not only the temporal but also the spiritual dominion throughout Western Asia, and along the southern shores of the Mediterranean. The Eastern empire at Constantinople had been weakened by bitter theological dissensions and heresies among the Christians; the votaries of the new, simple, unswerving faith of Mohammed were ardent and unanimous. In Egypt and Syria the Mohammedans were speedily victorious; the Latin Church and even the Latin language were swept out of North Africa. In Persia the Sassanian dynasty was overthrown, and although there was no immediate and total conversion of the people, Mohammedanism gradually superseded the ancient Zoroastrian cultus as the religion of the Persian State. It was not long before the armies of Islam had triumphed from the Atlantic coast to the Jaxartes river in Central Asia; and conversion followed, speedily or slowly, as the direct result of conquest. Moreover, the Mohammedans invaded Europe. In the south-west they subdued almost all Spain; and in the south-east they destroyed, some centuries later, the Greek empire, though not the Greek Church, and consolidated a mighty rulership at Constantinople.
With this prolonged conflict between Islam and Christianity along the borderlands of Europe and Asia began the era of those religious wars that have darkened the history of the Western nations, and have perpetuated the inveterate antipathy between Asiatic and European races, which the spread of Christianity into both continents had softened and might have healed. In the end Christianity has fixed itself permanently in Europe, while Islam is strongly established throughout half Asia. But the sharp collision between the two faiths, the clash of armies bearing the cross and the crescent, generated fierce fanaticism on both sides. The Crusades kindled a fiery militant and missionary spirit previously unknown to religions, whereby religious propagation became the mainspring and declared object of conquest and colonisation. Finally, in the sixteenth and seventeenth centuries the great secession from the Roman Church divided the nations of Western Europe into hostile camps, and throughout the long wars of that period political jealousies and ambitions were inflamed by religious animosities. In Eastern Europe the Greek Church fell under almost complete subordination to the State.
The history of Europe and Western Asia records, therefore, a close connection and community of interests between the States and the orthodox faiths; a combination which has had a very potent influence, during many centuries, upon the course of civil affairs, upon the fortunes, or misfortunes, of nations. Up to the sixteenth century, at least, it was universally held, by Christianity and by Islam, that the State was bound to enforce orthodoxy; conversion and the suppression or expulsion of heretics were public duties. Unity of creed was thought necessary for national unity—a government could not undertake to maintain authority, or preserve the allegiance of its subjects, in a realm divided and distracted by sectarian controversies. On these principles Christianity and Islam were consolidated, in union with the States or in close alliance with them; and the geographical boundaries of these two faiths, and of their internal divisions respectively, have not materially changed up to the present day.
Let me now turn to the history of religion in those countries of further Asia, which were never reached by Greek or Roman conquest or civilisation, where the ancient forms of worship and conceptions of divinity, which existed before Christianity and Islam, still flourish. And here I shall only deal with the relations of the State to religion in India and China and their dependencies, because these vast and populous empires contain the two great religions, Hinduism and Buddhism, of purely Asiatic origin and character, which have assimilated to a large extent, and in a certain degree elevated, the indigenous polytheism, and which still exercise a mighty influence over the spiritual and moral condition of many millions.
We know what a tremendous power religion has been in the wars and politics of the West. I submit that in Eastern Asia, beyond the pale of Islam, the history of religion has been very different. Religious wars—I mean wars caused by the conflict of militant faiths contending for superiority—were, I believe, unknown on any great scale to the ancient civilisations. It seems to me that until Islam invaded India the great religious movements and changes in that region had seldom or never been the consequence of, nor had been materially affected by, wars, conquests, or political revolutions.
Throughout Europe and Mohammedan Asia the indigenous deities and their temples have disappeared centuries ago; they have been swept away by the forces of Church and State combined to exterminate them; they have all yielded to the lofty overruling ideal of monotheism. But the tide of Mohammedanism reached its limit in India; the people, though conquered, were but partly converted, and eastward of India there have been no important Mohammedan rulerships. On this side of Asia, therefore, two great religions, Buddhism and Brahmanism, have held their ground from times far anterior to Christianity; they have retained the elastic comprehensive character of polytheism, purified and elevated by higher conceptions, developed by the persistent competition of diverse ideas and forms among the people, unrestrained by attempts of superior organised faiths to obliterate the lower and weaker species. In that region political despotism has prevailed immemorially; religious despotism, in the sense of the legal establishment of one faith or worship to the exclusion of all others, of uniformity imposed by coercion, of proselytism by persecution, is unknown to history: the governments have been absolute and personal; the religions have been popular and democratic. They have never been identified so closely with the ruling power as to share its fortunes, or to be used for the consolidation of successful conquest. Nor, on the other hand, has a ruler ever found it necessary, for the security of his throne, to conform to the religion of his subjects, and to abjure all others. The political maxim, that the sovereign and his subjects should be of one and the same religion,[59] has never prevailed in this part of the world. And although in India, the land of their common origin, Buddhism widely displaced and overlaid Brahmanism, while it was in its turn, after several centuries, overcome and ejected by a Brahmanic revival, yet I believe that history records no violent contests or collisions between them; nor do we know that the armed force of the State played any decisive part in these spiritual revolutions.
I do not maintain that Buddhism has owed nothing to State influence. It represents certain doctrines of the ancient Indian theosophy, incarnate, as one might say, in the figure of a spiritual Master, the Indian prince, Sakya Gautama, who was the type and example of ascetic quietism; it embodies the idea of salvation, or emancipation attainable by man's own efforts, without aid from priests or divinities. Buddhism is the earliest, by many centuries, of the faiths that claim descent from a personal founder. It emerges into authentic history with the empire of Asoka, who ruled over the greater part of India some 250 years before Christ, and its propagation over his realm and the countries adjacent is undoubtedly due to the influence, example, and authority of that devout monarch. According to Mr. Vincent Smith, from whose valuable work on the Early History of India I take the description of Asoka's religious policy, the king, renouncing after one necessary war all further military conquest, made it the business of his life to employ his autocratic power in directing the preaching and teaching of the Law of Piety, which he had learnt from his Buddhist priesthood. All his high officers were commanded to instruct the people in the way of salvation; he sent missions to foreign countries; he issued edicts promulgating ethical doctrines, and the rules of a devout life; he made pilgrimages to the sacred places; and finally he assumed the yellow robe of a Buddhist monk. Asoka elevated, so Mr. Smith has said, a sect of Hinduism to the rank of a world-religion. Nevertheless, I think it may be affirmed that the emperor consistently refrained from the forcible conversion of his subjects, and indeed the use of compulsion would have apparently been a breach of his own edicts, which insist on the principle of toleration, and declare the propagation of the Law of Piety to be his sole object. Asoka made no attempt to persecute Brahmanism; and it seems clear that the extraordinary success of Buddhism in India cannot be attributed to war or to conquest. To imperial influence and example much must be ascribed, yet I think Buddhism owed much more to its spiritual potency, to its superior faculty of transmuting and assimilating, instead of abolishing, the elementary instincts and worships, endowing them with a higher significance, attracting and stimulating devotion by impressive rites and ceremonies, impressing upon the people the dogma of the soul's transmigration and its escape from the miseries of sentient existence by the operation of merits. And of all great religions it is the least political, for the practice of asceticism and quietism, of monastic seclusion from the working world, is necessarily adverse to any active connection with mundane affairs.
I do not know that the mysterious disappearance of Buddhism from India can be accounted for by any great political revolution, like that which brought Islam into India. It seems to have vanished before the Mohammedans had gained any footing in the country. Meanwhile Buddhism is said to have penetrated into the Chinese empire by the first century of the Christian era. Before that time the doctrines of Confucius and Laotze were the dominant philosophies; rather moral than religious, though ancestral worship and the propitiation of spirits were not disallowed, and were to a certain extent enjoined. Laotze, the apostle of Taoism, appears to have preached a kind of Stoicism—the observance of the order of Nature in searching for the right way of salvation, the abhorrence of vicious sensuality—and the cultivation of humility, self-sacrifice, and simplicity of life. He condemned altogether the use of force in the sphere of religion or morality; though he admitted that it might be necessary for the purposes of civil government. The system of Confucius inculcated justice, benevolence, self-control, obedience and loyalty to the sovereign—all the civic virtues; it was a moral code without a metaphysical background; the popular worships were tolerated, reverence for ancestors conduced to edification; the gods were to be honoured, though it was well to keep aloof from them; he disliked religious fervour, and of things beyond experience he had nothing to say.
