Slavery is the medium through which the corrupt passions of men flow with resistless power. Beneath its influence every plant of virtue sickens and dies. Its putrid form taints the air which we breathe, and exhales all manner of foul odors, which render it so obnoxious to truth and purity, that these angels would speedily end its existence, if it were not for the support it derives from other sources than itself. Although coarse and brawny in its outward appearance, yet it is within full of disease; and nothing but continual doses of medicine enable it to present the appearance of life. It is said that a celebrated magnetiser, once preserved a dead body from putrefaction for a long time, by the power of magnetism. At length he withdrew the magnetising power, and the body instantly crumbled to atoms. Thus with Slavery; withdraw the enchantments from it, which priests, politicians, and speculators have thrown around it, and it expires of its own corruption. It lives only by this outward support, just as the virtue of some men is caused only by their being paid or praised for it. Apply, then, the finger of truth to its gigantic form; let but the mighty arm of righteousness lay hold of these sustaining influences, and sweep them from it; and it will fall as quickly as a huge statue would, if the pedestal on which it stands should be removed from under it. Slavery, to be sure, reaches mountain high, towering over all other eminences in this nation; far above the highest steeple, or State-house cupola, (church and State;) yet tall and commanding as it is, it shall be laid lowly in the dust, if but truth can reach the props and guards which keep it alive. Herculean though it may be in strength, it shall then become powerless and impotent; the life that is in it being like the light of the moon, not its own, but derived from a source independent of itself. What then are the props of Slavery? They may be divided into two classes, political, and religious ones; or in other words, both church and state may be regarded as sustaining the dreadful system. It is recorded in history, that at one entrance to a certain island there was stationed an immense brazen statue astride the water which lay before the island; and that there was no ingress to the city, except by sailing betwixt the legs of this statue, each foot of which rested on a promontory of the island. Imagine, then, the great giant Slavery standing with one foot on the American Church, and the other on the Union, requiring all wishing to enter the port of popularity and renown, to run this gauntlet, and you have a faint idea of Slavery. It plants its right foot firmly on the government of the United States, and receives its principal support from that; but to make its foothold firm and sure, it extends its left foot to the Church, and there finds additional support. Without these two props, it cannot exist a moment.
