Doctrine and Covenants 101:79-80
"Therefore, it is not right that any man should be in bondage one to another. And for this purpose have I established the Constitution of this land, by the hands of wise men whom I raised up unto this very purpose, and redeemed the land by the shedding of blood."
David O. McKay

"If we would make the world better, let us foster a keener appreciation for the the freedom and liberty guaranteed by the government of the United States as framed by the founders of this nation. Here again self-proclaimed progressives cry that such old-time adherence is out of date. But there are some fundamental principles of this republic which, like eternal truths, never get out of date, and which are applicable at all times to liberty-loving peoples. Such are the underlying principles of the Constitution, a document framed by patriotic, freedom-loving men, who Latter-day Saints declare were inspired by the Lord" (Conference Report, October 1940, p. 104)
