"Of all the dispositions and habits which lead to political prosperity, Religion and Morality are indispensable supports. In vain would that man claim the tribute of Patriotism who should labor to subvert these great pillars of human happiness, these firmest props of the duties of Men and Citizens. … And let us with caution indulge the supposition that morality can be maintained without religion. Whatever may be conceded to the influence of refined education on minds of peculiar structure, reason and experience both forbid us to expect that national morality can prevail in exclusion of religious principle."
George Washington, First President of the United States
