"I wish to say with all the earnestness I possess that when you see any curtailment of these liberties I have named, when you see government invading any of these realms of freedom which we have under our Constitution, you will know that they are putting shackles on your liberty, and that tyranny is creeping upon you, no matter who curtails these liberties or who invades these realms, and no matter what the reason and excuse therefore may be.

"I say to you that the price of liberty is and always has been blood, human blood, and if our liberties are lost, we shall never regain them except at the price of blood. They must not be lost.” [The Improvement Era, 43, [July 1940] 444.]

And the scary part...
"I say unto you with all the soberness I can, that we stand in danger of losing our liberties, and that once lost, only blood will bring them back; and we of this church will, in order to keep the Church going forward, have more sacrifices to make, and more persecutions to endure than we have yet known. If the conspiracy comes here it will probably come in its full vigor and there will be a lot of vacant places among those who guide and direct, not only this government, but also this Church of ours."
J. Reuben Clark [CR Apr 1944 & 1952]

Let every loyal member of the Church look down with scorn upon any man or woman who would undermine that Constitution.

Perhaps the most important of the great fundamentals of the inspired Constitution is the principle of popular sovereignty: The people are the source of government power. Along with many religious people, Latter-day saints affirm that God gave the power to people, and the people consented to a constitution that delegated certain powers to the government. Sovereignty is not inherent in a state or nation just because it has the power that comes from the force of arms. Sovereignty does not come from the divine right of a king, who grants his subjects such power as he pleases or is forced to conced.  The sovereign power is in the people.  (Dallin H. Oaks, The Divinely Inspired Constitution, Ensign February 1992)

The fifth and final principle that is basic to our understanding of the Constitution is that governments should have only limited powers. The important thing to keep in mind is that the people who have created their government can give to that government only such powers as they, themselves, have in the first place. Obviously, they cannot give that which they do not possess.

By deriving its just powers from the governed, government becomes primarily a mechanism for defense against bodily harm, theft, and involuntary servitude. It cannot claim the power to redistribute money or property nor to force reluctant citizens to perform acts of charity against their will. Government is created by the people. The creature cannot exceed the creator. (Ezra Taft Benson, Ensign, Sept. 1987, p. 8)

In the next canvas we shall be influenced by no party consideration…the partisans in this county who expect to divide the friends of humanity and equal rights will find themselves mistakes — we care not a fig for Whig or Democrat; they are both alike to us; but we shall go for our friends, our tried friends, and that cause of human liberty which is the cause of God. We are aware that ‘divide and conquer’ is the watchword with many, but with us it cannot be done — we love too well — we have suffered too much to be easily duped — we have no cat’s paws amongst us.

The real purpose of the Constitution was the preservation of liberty. It's not the Constitution that gives us our freedom; that comes from the Creator. But if we cherish freedom, the Constitution is needed to keep the power seekers from usurping that freedom and to hold government in check.

The time has come to act. May future generations look back on our work and say that these were men and women who, in a moment of great crisis, stood up to the politicians, the opinion-molders, and the establishment, and saved their country.

Next to being one in worshiping God, there is nothing in this world upon which this Church should be more united than in upholding and defending the Constitution of the United States!

...you cannot fully live the gospel without working to save freedom and the Constitution ...our stand for freedom is a most basic part of our religion.

Teachings and ideologies subversive to the fundamental principles of this great Republic, which are contrary to the Constitution of the United States, or which are detrimental to the progress of the Church of Jesus Christ of Latter-day Saints, will be condemned, whether advocated by Republicans or Democrats.
