"Not for nothing did the founders of the American republic insist that its functioning was unimaginable without the Christian religion. The purely negative aspects of the American constitution, namely the balance of powers that protects minority interests, means nothing without transcendent trust in something higher than the elements that constitute the body politic."

"We have no government armed with power capable of contending with human passions unbridled by morality and religion. Avarice, ambition, revenge, or gallantry, would break the strongest cords of our Constitution as a whale goes through a net. Our Constitution was made only for a moral and religious people. It is wholly inadequate to the government of any other." --October 11, 1798
