The inspired rights of the constitution of the United States will be part of the political foundation of the Lord’s government during the Millennial century. (See What was inspired?) How can I say that? Because these inspired rights are eternal principles. In his prayer offered at the dedication of the Kirtland Temple, Ohio, 1836, Joseph Smith asked that the principles of the Constitution might be established forever. (D&C 109:54) The inalienable freedoms that the founders of the United States entered into the Constitution were given them by the inspiration of the Lord (See The Constitution – a Heavenly Banner) and applies to all flesh (See D&C 98:5 | 101:77), not only to the people of the United States. (See The Constitution – For All Mankind)

Righteous people from many faiths will live in the Millennium after the Lord’s second coming. During the Millennium, the Lord’s political government will protect them in their inalienable rights while the gospel will be preached to them.

Orson Pratt:

With all its glory and greatness and perfection, [the Constitution] was only a steppingstone to a form of government infinitely greater and more perfect—a government founded upon Divine laws, with all its institutions, ordinances, and officers appointed by the God of heaven.

Brigham Young:

Now I want to give you these few words – the kingdom of God will protect every person, every sect and all people upon the face of the whole earth, in their legal rights. I shall not tell you the names of the members of this kingdom, neither shall I read to you its constitution, but the constitution was given by revelation. The day will come when it will be organized in strength and power.

Joseph Smith:

Have mercy, O Lord, upon all the nations of the earth; have mercy upon the rulers of our land; may those principles, which were so honorably and nobly defended, namely, the Constitution of our land, by our fathers, be established forever.

D&C 109:54. Prayer offered at the dedication of the temple at Kirtland, Ohio, March 27, 1836.

Melvin J. Ballard:

The Lord established the Constitution of the United States for the blessing of all flesh (D&C 101:77). In my soul I believe that that is part of the great Kingdom of God, the political part .. God’s word shall not fail when He predicted that the instrument known as the Constitution of the United States, the Spirit of liberty established here by a few weak colonists, was His order of things for the government of men, and it should roll forth to fill the whole earth.*

* See Daniel 2:34-35, 44.
General Conference, Oct. 1918.

Brigham Young:

When the day comes in which the Kingdom of God will bear rule, the flag of the United States will proudly flutter unsullied on the flag staff of liberty and equal rights, without a spot to sully its fair surface the glorious flag our fathers have bequeathed to us will then be unfurled to the breeze by those who have power to hoist it aloft and defend its sanctity.

Christopher S. Bentley:

Freedom will be established for the entire human race. Therefore, it should come as no surprise to Latter-day Saints that the Lord has already established the political foundation upon which it will be built: the Constitution of the United States. Isaiah called it the law of Zion (Isaiah 2:3). Indeed, this is why the Lord told us through his Prophet Joseph Smith that the Constitution should be “maintained for the rights and protection of all flesh” (D&C 101:77), and that this sacred “principle of freedom .. belongs to all mankind” (D&C 98:5).

Orson F. Whitney:

I revere the Constitution as an emanation of Divinity and, I believe, we will yet see the principles upon which this great government was founded, – principles of justice, freedom and equality, – prevail the wide world over .. God did not found this nation for a mere handful of his children. He founded it for all mankind. And when he bound together these United States, it was but a type, a symbol and a foreshadowing of a united world. All nations will yet join hands as these States have done, and this, in my opinion, will only be the prelude to a work still greater, lifting from earth that curse which has so long rested upon it, and uniting it as a glorious link in the grand chain of redeemed worlds that circle about the throne of their Creator.

Collected Discources, Vol. 3. 1892.

Joseph F. Smith:

This great American nation the Almighty raised up by the power of his omnipotent hand, that it might be possible in the latter days for the kingdom of God to be established in the earth .. His hand has been over this nation, and it is his purpose and design to enlarge it—make it glorious above all others, and to give it dominion, and power over the earth, to the end that those who are kept in bondage and serfdom may be brought to the enjoyment of the fullest freedom and liberty of conscience possible for intelligent men to exercise in the earth.

Gospel Doctrine, p. 409.

Charles W. Penrose:

In section 101 the Lord speaks about the constitution of this land. He says it was framed by wise men whom he raised up for that very purpose. What for? To maintain the rights and privileges “of all flesh” (D&C 101:77, 80). Not alone the people of this land. The principles of that great instrument are to go forth to the nations, and the time will come when they will prevail, just as sure as the sun shines even when it appears to be in darkness and the clouds are over it.

Conference Report, Apr. 1917, p. 20.

Brigham Young:

What do I understand by a theocratic government? One in which all laws are enacted and executed in righteousness, and whose officers possess that power which proceedeth from the Almighty. That is the kind of government I allude to when I speak of a theocratic government, or the kingdom of God upon the earth .. few, if any, understand what a theocratic government is. In every sense of the word, it is a republican government .. but its subjects will recognize the will and dictation of the Almighty .. The Constitution and laws of the United States resemble a theocracy more closely than any government now on the earth, or that ever has been, so far as we know, except the government of the children of Israel to the time when they elected a king (1 Sam. 8:19) .. The kingdom of God will be extended over the earth and it is written, “I will make thine officers peace, and thine exactors righteousness” (Isaiah 60:17). Is that day ever coming? It is and the doctrine we preach leads to that point. Even now the form of the Government of the United States differs but little from that of the kingdom of God .. Whoever lives to see the kingdom of God fully established upon the earth will see a government that will protect every person in his rights. If that government was now reigning upon this land of Joseph, you would see the Roman Catholic, the Greek Catholic, the Episcopalian, the Presbyterian, the Methodist, the Baptist, the Quaker, the Shaker, the Hindoo, the Mahometan, and every class of worshippers most strictly protected in all their municipal rights and in the privilege of worshipping who, what, and when they pleased, not infringing upon the rights of others (A of F 1:11).

It is my conviction .. that when the Lord comes, the Stars and Stripes will be floating on the breeze over this people.
