Alexis de Tocqueville was the famous 19th century French statesman, historian and social philosopher. He traveled to America in the 1830s to discover the reasons for the incredible success of this new nation. He published his observations in his classic two-volume work, Democracy in America. He was especially impressed by America's religious character. Here are some startling excerpts from Tocqueville's great work:

Upon my arrival in the United States the religious aspect of the country was the first thing that struck my attention; and the longer I stayed there, the more I perceived the great political consequences resulting from this new state of things.

In France I had almost always seen the spirit of religion and the spirit of freedom marching in opposite directions. But in America I found they were intimately united and that they reigned in common over the same country.

Religion in America...must be regarded as the foremost of the political institutions of that country; for if it does not impart a taste for freedom, it facilitates the use of it. Indeed, it is in this same point of view that the inhabitants of the United States themselves look upon religious belief.

I do not know whether all Americans have a sincere faith in their religion -- for who can search the human heart? But I am certain that they hold it to be indispensable to the maintenance of republican institutions. This opinion is not peculiar to a class of citizens or a party, but it belongs to the whole nation and to every rank of society.

In the United States, the sovereign authority is religious...there is no country in the world where 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 powerfully felt over the most enlightened and free nation of the earth.

In the United States, the influence of religion is not confined to the manners, but it extends to the intelligence of the people...

Christianity, therefore, reigns without obstacle, by universal consent...

I sought for the key to the greatness and genius of America in her harbors...; in her fertile fields and boundless forests; in her rich mines and vast world commerce; in her public school system and institutions of learning. I sought for it in her democratic Congress and in her matchless Constitution.

Not until I went into the churches of America and heard her pulpits flame with righteousness did I understand the secret of her genius and power.

America is great because America is good, and if America ever ceases to be good, America will cease to be great.

The safeguard of morality is religion, and morality is the best security of law as well as the surest pledge of freedom.

The Americans combine the notions of Christianity and of liberty so intimately in their minds, that it is impossible to make them conceive the one without the other

Christianity is the companion of liberty in all its conflicts -- the cradle of its infancy, and the divine source of its claims.

Tocqueville gives this account of a court case in New York:

While I was in America, a witness, who happened to be called at the assizes of the county of Chester (state of New York), declared that he did not believe in the existence of God or in the immortality of the soul. The judge refused to admit his evidence, on the ground that the witness had destroyed beforehand all confidence of the court in what he was about to say. The newspapers related the fact without any further comment. The New York Spectator of August 23rd, 1831, relates the fact in the following terms:

"The court of common pleas of Chester county (New York), a few days since rejected a witness who declared his disbelief in the existence of God. The presiding judge remarked, that he had not before been aware that there was a man living who did not believe in the existence of God; that this belief constituted the sanction of all testimony in a court of justice: and that he knew of no case in a Christian country, where a witness had been permitted to testify without such belief."
