De Tocqueville was a French citizen, and although not classified as a Founding Father, provided a unique glimpse of the early Republic. De Tocqueville traveled to the United States in 1831 and chronicled his observations in his book Democracy in America.
"There is an innumerable multitude of sects in the United States. All differ in the worship one must render to the Creator, but all agree on the duties of men toward one another. Each sect therefore adores God in its manner, but all sects preach the same morality in the name of God.

Religion, which, among Americans, never mixes directly in the government of society, should therefore be considered as the first of their political institutions; for if it does not give them the taste for freedom, it singularly facilitates their use for it."
"...there is no country in the whole world in which the Christian religion retains a greater influence over the souls of men than in America; and there can be no greater proof of its utility, and of its conformity to human nature, than that its influence is most powerfully felt over the most enlightened and free nation of the earth."
