Christian citizens of all the States are directly responsible for the existence of slavery in the District of Columbia, and they should not be content until that foul pollution is wiped away from the Capital of our country. Slavery at Washington is especially a national disgrace, a blistering shame, a satire upon our professions. When the foreign minister or visitor comes to our country, and goes to Washington, he sees in the streets, at the hotels, and everywhere, a poor, stupid, oppressed people, whose very speech and looks betray their ignorance and servility. Ah! Is this American freedom? Equality? Republicanism? Upon inquiry, he finds that one-seventh of all the people are in this state of servile wretchedness. And when a member of Congress from a free State goes to the proud Capital of his country, he beholds passing by the tall and splendid buildings of the government, droves of men, women and children, chained together,--some sullenly indifferent to their fate--others weeping as if their hearts would break.--Who are these? American citizens! Men, as white as some members of Congress, and women as fair as their wives and as virtuous as their daughters, are cried off at auction to the highest bidder, in Washington! There our senators and representatives sit and legislate, in sight of the slave prison, and slave market--in hearing of the clanking of chains, and coffles,--and of the wail of slave mothers, weeping for their children, because they are "Gone, gone, sold and gone." They are also responsible for the extension of slavery into territory now free. If they go not to the utmost verge of their power to save the Lord's free earth from the overspreading and blighting curse of slavery, they cannot but be execrated by an enlightened posterity. But more than all this. A christian is a citizen of the world, and hence is required to employ the whole force of his moral and political power for the extirpation of slavery from every State in the Union, and from every country on the globe. The influence of an intelligent, active christian citizen is worldwide. He cannot be the dupe or tool of any party; he is never shackled by party organizations; he does not commit the keeping of his conscience to political leaders. He sincerely loves God, believes the Bible, and loves his fellow-men, because they are men. Prejudice, caste, and all other relics of barbarism, he has thrown away. He talks, votes and prays for universal liberty and righteousness. In the pulpit, in the shop, on the farm, anywhere, everywhere the whole weight of his influence is thrown against slavery in the territories, in the District of Columbia, in the States, and against it wherever it exists in the world. As he seeks for the physical, intellectual and moral improvement and happiness of all men, he must desire intensely the speedy extirpation of slavery from the earth.
