Joseph Smith, in History of the Church, 6:197-98, 205-206

Born in a land of liberty, and breathing an air uncorrupted with the sirocco of barbarous climes, I ever feel a double anxiety for the happiness of all men, both in time and in eternity.

My cogitations, like Daniel’s, have for a long time troubled me, when I viewed the condition of men throughout the world, and more especially in this boasted realm, where the Declaration of Independence “holds these truths to be self-evident, that all men are created equal; that they are endowed by their Creator with certain unalienable rights; that among these are life, liberty, and the pursuit of happiness;” but at the same time some two or three millions of people are held as slaves for life, because the spirit in them is covered with a darker skin than ours; and hundreds of our own kindred for an infraction, or supposed [198] infraction, of some over-wise statute, have to be incarcerated in dungeon gloom, or penitentiaries, while the duellist, the debauchee, and the defaulter for millions, and criminals, take the uppermost rooms at feasts, or, like the bird of passage, find a more congenial clime by flight. 

The wisdom which ought to characterize the freest, wisest, and most noble nation of the nineteenth century, should, like the sun in his meridian splendor, warm every object beneath its rays; and the main efforts of her officers, who are nothing more nor less than the servants of the people, ought to be directed to ameliorate the condition of all, black or white, bond or free; for the best of books says, “God hath made of one blood all nations of men for to dwell on all the face of the earth.” 

Our common country presents to all men the same advantages, the facilities, the same prospects, the same honors, and the same rewards; and without hypocrisy, the Constitution, when it says, “We, the people of the United States, in order to form a more perfect union, establish justice, ensure domestic tranquility, provide for the common defense, promote the general welfare, and secure the blessings of liberty to ourselves and our posterity, do ordain and establish this Constitution for the United States of America,” meant just what it said without reference to color or condition, ad infinitum…. 

[205]

…Petition, also, ye goodly inhabitants of the slave States, your legislators to abolish slavery by the year 1850, or now, and save the abolitionist from reproach and ruin, infamy and shame.

Pray Congress to pay every man a reasonable price for his slaves out of the surplus revenue arising from the sale of public lands, and from the deduction of pay from the members of Congress.

Break off the shackles from the poor black man, and hire him to labor like other human beings; for “an hour of virtuous liberty on earth is worth a whole eternity of bondage.” Abolish the practice in the army and navy of trying men by court-martial for desertion. If a soldier or marine runs away, send him his wages, with this instruction, that his country will never trust him again; he has forfeited his honor.

Make honor the standard with all men. Be sure that good is rendered for evil in all cases; and the whole nation, like a kingdom of kings and priests, will rise up in righteousness, and be respected as wise and worthy an earth, and as just and holy for heaven, by Jehovah, the Author of perfection.

More economy in the national and state governments would make less taxes among the people; more equality through the cities, towns, and country, would make less distinction among the people; and more honesty and familiarity in societies would make less hypocrisy and flattery in all branches of the community; and open, frank, candid decorum to all men, in this boasted land of liberty, would beget esteem, [206] confidence, union, and love; and the neighbor from any state or from any country, of whatever color, clime or tongue, could rejoice when he put his foot on the sacred soil of freedom, and exclaim, The very name of “American” is fraught with “friendship!” Oh, then, create confidence, restore freedom, break down slavery, banish imprisonment for debt, and be in love, fellowship and peace with all the world!
