The Conflict with Slavery, Part 1, from Volume VII‪,‬

Members of one confederacy, children of one family, the curse and the shame, the sin against our brother, and the sin against our God, all the iniquity of slavery which is revealed to man, and all which crieth in the ear, or is manifested to the eye of Jehovah, will assuredly be visited upon all our people. Why, then, should we stretch out our hands towards our Southern brethren, and like the Pharisee thank God we are not like them? For so long as we practically recognize the infernal principle that "man can hold property in man", God will not hold us guiltless. So long as we take counsel of the world's policy instead of the justice of heaven, so long as we follow a mistaken political expediency in opposition to the express commands of God, so long will the wrongs of the slaves rise like a cloud of witnesses against us at the inevitable bar.
