On my arrival in the United States it was the religious aspect of the country that first struck my eye. As I prolonged my stay, I perceived the great political consequences that flowed from these new facts. Among us, I had seen the spirit of religion and the spirit of freedom almost always move in contrary directions. Here I found them united intimately with one another: they reigned together on the same soil.
