"Whereas, it is the duty of all
nations to acknowledge the Providence of Almighty God, to obey his will, to be
grateful for his benefits, humbly to implore his protection and favor . . . .
. . . that we may then unite in most
humbly offering our prayers and supplication to the great Lord and Ruler of
Nations, and beseech Him to pardon our national and other transgressions; to
enable us all, whether in public or private stations, to perform our several and
relative duties properly and punctually; to render our national government a
blessing to all the people, by constantly being a government of wise, just, and
constitutional laws, discreetly and faithfully executed and obeyed; to protect
and guide all sovereigns and nations (especially such as have shown kindness to
us), and to bless them with good governments, peace, and concord; to promote
the knowledge and practice of true religion and virtue, and the increase of
science, among them and us; and, generally, to grant unto all mankind such a
degree of temporal prosperity as He alone knows to be best.
"
George Washington, October 3, 1789, in the first proclamation of a
National Day of Thanksgiving.
