Before, in pursuing this method of frigid calculation, the Christian doctrine be weighed against the several systems with which it must contend ere it wins its universal triumph, it is proper to inquire—what is the probability that a collision will actually take place. To estimate fairly this probability, those who are but slenderly acquainted with the religious world, in the British Islands, in America, and in the Protestant states of the continent, must understand, much better than generally they do, the precise nature of the remarkable revolution that has, within the last thirty years, been effected in the sentiments of Christians on the subject of the diffusion of their religion. Such slenderly-informed persons may very naturally imagine that the prodigious efforts that have of late been made to diffuse Christianity through the world have sprung simply from a heat and excitement, in its nature transient, and which, therefore, must be expected soon to subside. But this supposition will be found to be incomplete and erroneous. A stir and kindling of feeling has no doubt happened; but this feeling, and the activities which followed from it, have given occasion to the resurrection, so to speak, of a capital article of Christian morals, which, after lying almost latent for centuries, stands forth in undisputed and prominent authority in the modern code of religious duty. This recovered principle is now constantly recognized and enforced; and it is seen to exert its influence, not merely within the circles of central movement, but even in the remotest orbits of religious feeling, where warmth and energy are manifestly not excessive.

The founder of Christianity left with his disciples the unlimited injunction to go forth into all the world, and to preach the Gospel to every creature. This command, corroborated by others of equivalent import, and enforced by the very nature of the Christian doctrine, and by the spirit of Christian charity, is now understood and acknowledged, in a manner new to the church, to be of universal obligation, so that no Christian, how obscure soever may be his station, or small his talents, or limited his means, can be held to stand altogether excused from the duty of fulfilling, in some way, the last mandate of his Lord. Thus understood, this command makes every believer a preacher and a missionary; or at least obliges him to see to it, so far as his ability extends, that the labors of diffusive evangelization are actually performed by a substitute.

Before the commencement of the recent missionary efforts, there had been missions to the heathen. But these, if carried on with anything more than a perfunctory assiduity, were anomalous to the general feeling of Christians, and sprung from the exemplary zeal of individuals. But the modern missions are maintained neither by the zeal of the few, nor by the mere zeal of the many; but rather by the deep-seated impulsive power of a grave conviction, pressing on the conscience even of the inert and the selfish—and much more on the hearts of the fervent and devoted—that a Christian has no more liberty to withhold his aid and service from these evangelizing associations than he has to abandon the duties of common life; and that, for a man to profess hope in Christ, and to deny what he might spare to promote the diffusion of the Gospel, is the most egregious of all practical solecisms.

Those who are ignorant of this remarkable revolution of sentiment, or who may be sceptical concerning it, would do well to take up, at hazard, any dozen of the discourses, and reports, and tracts, that are yearly, and monthly, and weekly, flowing from the religious press, and among which they will hardly find one that does not assume this as an admitted principle, and as the ultimate motive of every hortatory appeal. And if, among these ephemera, there are any, and such are not seldom to be found, that bear the stamp of superior intelligence, it will be seen almost invariably, that the reasoner summons all the force of his mind, not so much to prove that every Christian is bound to promote the diffusion of scriptural knowledge, as by some new ingenuity of illustration to place the acknowledged duty in a stronger light, or to show in what manner it bears upon the specific object for which he pleads. And it is to be noted that these popular addresses exhibit, for the most part, much more of the gravity and calmness which naturally belong to the style of those who feel that they are standing upon undisputed ground, than of the solicitude, or the inflammatory verbosity and turgidness of writers who are laboring to fan a decaying blaze of indefensible enthusiasm.

Or again: it may well be inferred that the modern missionary zeal springs from motives of a substantial and permanent kind, since they affect, without exception, every body of Christians (holding the doctrines of the Reformation) and are felt in the same manner by the Christians of every Protestant community of Europe. And moreover the feeling has not declined, but has sensibly increased since the first years of its activity; and it has endured the trial, in some instances, of severe and long-continued discomfitures, or of partial success. These are indications of a spring of action far more sedate and enduring than any feverish excitement can ever supply.

But if the extent, and the power, and the promise of the existing missionary zeal are to be duly estimated, the inquirer should visit the homes of our religious folks; or enter the schools in which their children are trained, and there learn what is the doctrine inculcated upon those who are rising up to take their place on the arena of life: or let him listen to the hymns they lisp, and examine the tracts they read, and he will meet the same great principle in a thousand manners enforced, namely—That it is the duty of every Christian, young or old, rich or poor, to take part in sending the Gospel to all nations. Or let the observer notice the Missionary Box, in the school-room, in the nursery, in the shop-parlor, in the farm-house kitchen, in the cottage, of the religious; and let him mark the multiform contrivances for swelling the amount of the revenues of Christian charity, devised, and zealously persisted in, by youths and by little ones, whose parents, at the same age, thought of nothing but of cakes and sports.

And does all this steady movement, this wide-spreading and closely-compacted system of united effort, this mechanism in which infancy as well as maturity takes its part, indicate nothing for futurity? Shall it all have passed away and be forgotten with the present generation? If indeed it were confined to a sect, or to a province, or to a country, it might, though that were unlikely; but not if it be the common style of Christian feeling in every part of the world where spiritual Christianity exists at all. Particular associations may be dissolved, and particular schemes may be broken up; and standard-bearers in the sacred cause may faint; and the zeal of certain communities may fade; or political disasters may here and there bring ruin upon pious labors; but unless devastation universal sweeps over the face of the civilized world, the doctrine of missionary zeal, which has been broad-cast over Christendom, in the present day, will not fail of coming to its harvest. And now, if there are any who wish ill to Christianity, let them hasten to prevent the measures of its friends, let them teach their babes to hate the Gospel; for those who love it are taking such means to insure its future triumph as can hardly fail of success, and such as, on common grounds of calculation, make it likely that even the sons and the daughters of the present race of infidels may be involved in the approaching conquests of the Son of David; and that they shall actually join in the loud hosanna, announcing his accession to the throne of universal empire.

It is then more than barely probable—it is almost certain—that the attempt to offer Christianity to all nations, will not soon be abandoned. The next question is this—whether, on grounds of frigid calculation, such attempts are recommended by any fair promise of success.

When the term calculation is used in reference to the diffusion of Christianity, a use of the word which perhaps may offend the ear of piety, an important distinction must be kept in view between that cordial admission of the Gospel which renovates the hearts of men individually, and that change of opinion and profession which may be brought about among a people by means that fall short of possessing efficiency to produce repentance and faith. And while the former must everywhere, at home or abroad, be the great object aimed at and desired by the Christian ministry, the latter is both in itself, even if nothing more were done, and as a preliminary, and a probable means conducing to the production of genuine piety, a most desirable and happy revolution. It is moreover a revolution which may be reckoned to lie within the range of human agency, when judiciously and perseveringly applied. For Christianity is a species of knowledge, in its nature communicable; and, as a system of opinions, or as a code of morals, it possesses a manifest superiority, if fairly brought into comparison with any existing religious system. And if it may reasonably be asked concerning any people—how shall they believe without a preacher? the converse question might, with little less confidence be put—how shall they not believe with one?

Pagan and Mohammedan nations ought to be thought of by a Christian people just as the master of a numerous household, if he be wise and benevolent, thinks of the untutored members of his family; for although no actual subjection is owned on the one side, or can be exercised on the other, there exists, virtually, the relationship and the responsibilities of that domination which is ever possessed by knowledge, intelligence, and virtue, over ignorance and degradation. Now, as the master of a family may, to a greater or less extent, infallibly succeed by zeal, affection, skill, and patience, in dispelling the superstitions and the ignorance which have happened to come under his roof; so, with zeal, affection, skill, and patience, proportioned to the greatness of the work, may the Christian nations at length effect a cleansing of the earth from the cruelties and impurities of polytheism.
