Our Founders saw a National Day of Prayer as a fitting observance, not unlike the establishment of Thanksgiving, of which George Washington wrote in 1777, “Being the day set apart by the Honorable Congress for public Thanksgiving and Praise; and duty calling us devoutly to express our grateful acknowledgements to God for the manifold blessings He has granted us, the General … earnestly exhorts, all officers and soldiers, whose absence is not indispensably necessary, to attend with reverence the solemnities of the day.”
“To the distinguished Character of Patriot, it should be our highest Glory to add the more distinguished Character of Christian. The signal Instances of providential Goodness which we have experienced and which have now almost crowned our labours with complete Success, demand from us in a peculiar manner the warmest returns of Gratitude and Piety to the Supreme Author of all Good.” –George Washington
