Our constitution was made only for a moral and religious people. It is wholly inadequate to the government of any other. - John Adams

Statesmen, my dear Sir, may plan and speculate for liberty, but it is Religion and Morality alone, which can establish the Principles upon which Freedom can securely stand. - John Adams

Men are qualified for liberty in exact proportion to their disposition to put moral chains upon their own appetites. - Edmund Burke

To compel a man to furnish contributions of money for the propagation of opinions which he disbelieves and abhors is sinful and tyrannical. - Thomas Jefferson

God who gave us life gave us liberty. And can the liberties of a nation be thought secure when we have removed their only firm basis, a conviction in the minds of the people that these liberties are of the gift of God? That they are not to be violated but with His wrath? Indeed, I tremble for my country when I reflect that God is just; that His justice cannot sleep forever. - Thomas Jefferson

A general dissolution of the principles and manners will more surely overthrow the liberties of America than the whole force of the common enemy. - Samuel Adams

The powers delegated by the proposed Constitution to the federal government are few and defined. Those which are to remain in the State governments are numerous and indefinite. - James Madison

The ultimate touchstone of constitutionality is the Constitution itself and not what we have said about it. - Justice Felix Frankfurter
