"I scarcely need to refer to the fact that the Houses of Congress, and so as I know the state legislatures, open their daily sessions with prayer.
The foundation of our independence and our Government rests upon basic religious convictions.
Back of the authority of our laws is the authority of the Supreme Judge of the World, to whom we still appeal for their final justification..."
All liberty is individual liberty...
The principle of equality is recognized. It follows inevitably from belief in the brotherhood of man through the fatherhood of God.
When once the right of the individual to liberty and equality is admitted, there is no escape from the conclusion that he alone is entitled to the rewards of his own industry...
It seems to me perfectly plain that the authority of law, the right to equality, liberty and property, under American institutions, have for their foundation reverence for God.
If we could imagine that to be swept away, these institutions of our American government could not long survive."
-- President Calvin Coolidge
"Without wishing to damp the ardor of curiosity or influence the freedom of inquiry, I will hazard a prediction that, after the most industrious and impartial researchers, the longest liver of you all will find no principles, institutions or systems of education more fit in general to be transmitted to your posterity than those you have received from your ancestors."
-- John Adams, letter to the young men of Philadelphia, 1798
"A constitution founded on these principles introduces knowledge among the people, and inspires them with a conscious dignity becoming freemen; a general emulation takes place, which causes good humor, sociability, good manners, and good morals to be general. That elevation of sentiment inspired by such a government, makes the common people brave and enterprising. That ambition which is inspired by it makes them sober, industrious, and frugal."
-- John Adams, Thoughts on Government, 1776
