The 1840s

We must onward to the fulfillment of our mission--to the entire development of the principle of our organization--freedom of conscience, freedom of person, freedom of trade and business pursuits, universality of freedom and equality. This is our high destiny, and in nature's eternal, inevitable decree of cause and effect we must accomplish it. All this will be our future history, to establish on earth the moral dignity and salvation of man--the immutable truth and beneficence of God. For this blessed mission to the nations of the world, which are shut out from the life-giving light of truth, has America been chosen; and her high example shall smite unto death the tyranny of kings, hierarchs, and oligarchs, and carry the glad tidings of peace and good will where myriads now endure an existence scarcely more enviable than that of beasts of the field. Who, then, can doubt that our country is destined to be the great nation of futurity?
