I am here reminded of what Professor Hodge says were the means relied on by the Saviour and Apostles for abolishing slavery. "It was," says he, "by teaching the true nature, dignity, equality, and destiny of men; by inculcating the principles of justice and love; and by leaving these principles to produce their legitimate effects in ameliorating the condition of all classes of society." I would not speak disparagingly of such a course of instruction; so far from it, I am ready to admit that it is indispensable for the removal of evils, in every age and among every people. When general instructions of this character shall have ceased to be given, then will all wholesome reforms have ceased also. But, I cannot approve of the Professor's object in this remark. This object is to induce his readers to believe, that these abstract and general instructions are all that is needed to effect the termination of slavery. Now, I maintain that one thing more is wanting; and that is, the application of these instructions--of the principles contained in them--to the evil in hand. As well may it be supposed, that the mechanic can accomplish his work without the application, and by the mere possession, of his tools, as that a given reformation can be effected by unapplied general principles. Of these principles, American philanthropists have been possessed from time immemorial; and yet all the while American slavery has been flourishing and growing strong. Of late, however, these principles have been brought to bear upon the system, and it manifestly is already giving way. The groans of the monster prove that those rays of truth, which did not disturb him whilst they continued to move in the parallel lines of abstractions and generalities, make it quite too hot for him since they are converged to a burning focus upon his devoted head. Why is it, for example, that the influence of the Boston Recorder and New-York Observer--why is it, that the influence of most of our titled divines--is decidedly hostile to the abolition of slavery? It is not because they are deficient in just general sentiments and principles respecting man's duties to God and his fellow man. It is simply because they stand opposed to the application of these sentiments and principles to the evil in question; or, in other words, stand opposed to the Anti-Slavery Society, which is the chosen lens of Divine Providence for turning these sentiments and principles, with all the burning, irresistible power of their concentration, against a giant wickedness. What is the work of the Temperance Societies, but to make a specific application of general truths and principles to the vice of intemperance? And the fact, that from the time of Noah's intoxication, until the organization of the American Temperance Society, the desolating tide of intemperance had been continually swelling, proves that this reliance on unapplied principles, however sound--this "faith without works"--is utterly vain. Nathan found that nothing, short of a specific application of the principles of righteousness, would answer in the case of the sin of adultery. He had to abandon all generalities and circuitousness, and come plump upon the royal sinner with his "Thou art the man." Those divines, whose policy it is to handle slaveholders "with gloves," if they must handle them at all, doubtless regard Nathan as an exceedingly impolite preacher.
