George Washington:
Farewell Address: The name of American, which belongs to you, in your national capacity, must always exalt the just pride of Patriotism, more than any appellation derived from local discriminations.
With slight shades of difference, you have the same religion" ...and later:
"...reason and experience both forbid us to expect, that national morality can prevail in exclusion of religious principle..."
“ It is impossible to rightly govern the world without God and Bible.”
“What students would learn in American schools above all is the religion of Jesus Christ.”
[speech to the Delaware Indian Chiefs May 12, 1779]
"To the distinguished character of patriot, it should be our highest glory to add the more distinguished character of Christian" [May 2, 1778, at Valley Forge]
During his inauguration, Washington took the oath as prescribed by the Constitution but added several religious components to that official ceremony. Before taking his oath of office, he summoned a Bible on which to take the oath, added the words “So help me God!” to the end of the oath, then leaned over and kissed the Bible.
Nelly Custis-Lewis (Washington’s adopted daughter):
Is it necessary that any one should [ask], “Did General Washington avow himself to be a believer in Christianity?" As well may we question his patriotism, his heroic devotion to his country. His mottos were, "Deeds, not Words"; and, "For God and my Country."
“ O Most Glorious God, in Jesus Christ, my merciful and loving Father; I acknowledge and confess my guilt in the weak and imperfect performance of the duties of this day. I have called on Thee for pardon and forgiveness of my sins, but so coldly and carelessly that my prayers are become my sin, and they stand in need of pardon.”
“ I have sinned against heaven and before Thee in thought, word, and deed. I have contemned Thy majesty and holy laws. I have likewise sinned by omitting what I ought to have done and committing what I ought not. I have rebelled against the light, despising Thy mercies and judgment, and broken my vows and promise. I have neglected the better things. My iniquities are multiplied and my sins are very great. I confess them, O Lord, with shame and sorrow, detestation and loathing and desire to be vile in my own eyes as I have rendered myself vile in Thine. I humbly beseech Thee to be merciful to me in the free pardon of my sins for the sake of Thy dear Son and only Savior Jesus Christ who came to call not the righteous, but sinners to repentance. Thou gavest Thy Son to die for me.”
[George Washington; from a 24 page authentic handwritten manuscript book dated April 21-23, 1752
William J. Johnson George Washington, the Christian (New York: The Abingdon Press, New York & Cincinnati, 1919), pp. 24-35.]
"Although guided by our excellent Constitution in the discharge of official duties, and actuated, through the whole course of my public life, solely by a wish to promote the best interests of our country;
yet, without the beneficial interposition of the Supreme Ruler of the Universe, we could not have reached the distinguished situation which we have attained with such unprecedented rapidity. To HIM, therefore, should we bow with gratitude and reverence, and endeavor to merit a continuance of HIS special favors".
[1797 letter to John Adams]
