1860s, Emancipation Proclamation (1863)
Context: And by virtue of the power, and for the purpose aforesaid, I do order and declare that all persons held as slaves within said designated States, and parts of States, are, and henceforward shall be free; and that the Executive government of the United States, including the military and naval authorities thereof, will recognize and maintain the freedom of said persons. And I hereby enjoin upon the people so declared to be free to abstain from all violence, unless in necessary self-defence; and I recommend to them that, in all cases when allowed, they labor faithfully for reasonable wages. And I further declare and make known, that such persons of suitable condition, will be received into the armed service of the United States to garrison forts, positions, stations, and other places, and to man vessels of all sorts in said service. And upon this act, sincerely believed to be an act of justice, warranted by the Constitution, upon military necessity, I invoke the considerate judgment of mankind, and the gracious favor of Almighty God.

This statement was made by an official representative of the U.S. during Washington's presidency, but is actually a line from the English version of the Treaty of Tripoli ( Article 11 http://avalon.law.yale.edu/18th_century/bar1796t.asp#art11), which was signed at Tripoli on November 4, 1796, and at Algiers on January 3, 1797. It received ratification unanimously from the U.S. Senate on June 7, 1797 and was signed into law by John Adams. The wording of the treaty is by Joel Barlow, U.S. Consul, who had served as Washington's chaplain, and was also a good friend of Paine and Jefferson; Article 11 of it reads:
::As the government of the United States of America is not in any sense founded on the Christian Religion,—as it has in itself no character or enmity against the laws, religion or tranquility of Musselmen,—and as the said States never have entered into any war or act of hostility against any Mehomitan nation, it is declared by the parties that no pretext arising from religious opinions shall ever produce an interruption of the harmony existing between the two countries.
