Thanksgiving Day
Proclamation
June 20, 1676

"The Holy God having by a long and Continual Series of his Afflictive dispensations in and by the present Warr with the Heathen Natives of this land, written and brought to pass bitter things against his own Covenant people in this wilderness, yet so that we evidently discern that in the midst of his judgements he hath remembered mercy, having remembered his Footstool in the day of his sore displeasure against us for our sins, with many singular Intimations of his Fatherly Compassion, and regard; reserving many of our Towns from Desolation Threatened, and attempted by the Enemy, and giving us especially of late with many of our Confederates many signal Advantages against them, without such Disadvantage to ourselves as formerly we have been sensible of, if it be the Lord's mercy that we are not consumed, It certainly bespeaks our positive Thankfulness, when our Enemies are in any measure disappointed or destroyed; and fearing the Lord should take notice under so many Intimations of his returning mercy, we should be found an Insensible people, as not standing before Him with Thanksgiving, as well as lading him with our Complaints in the time of pressing Afflictions:

The Council has thought meet to appoint and set apart the 29th day of this instant June, as a day of Solemn Thanksgiving and praise to God for such his Goodness and Favour, many Particulars of which mercy might be Instanced, but we doubt not those who are sensible of God's Afflictions, have been as diligent to espy him returning to us; and that the Lord may behold us as a People offering Praise and thereby glorifying Him; the Council doth commend it to the Respective Ministers, Elders and people of this Jurisdiction; Solemnly and seriously to keep the same Beseeching that being perswaded by the mercies of God we may all, even this whole people offer up our bodies and soulds as a living and acceptable Service unto God by Jesus Christ."

[The governing council of Charlestown, Massachusetts, June 20, 1676]

Nov 26, 1789
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, and humbly to implore His protection and favor, and Whereas both Houses of Congress have by their joint committee requested me to "recommend to the People of the United States a day of public thanks-giving and prayer to be observed by acknowledging with grateful hearts the many single favors of Almighty God, especially by affording them an opportunity peaceably to establish a form of government for their safety and happiness."
Now therefore I do recommend and assign Thursday the 26th day of November next to be devoted by the People of these States to the Service of that great and glorious Being, who is the beneficent Author of all the good that was, that is, or that will be. That we may then all unite in rendering unto Him our sincere and humble thanks, for His kind care and protection of the People of this country previous to their becoming a Nation, for the single and manifold mercies, and the favorable interpositions of His providence, which we experienced in the course and conclusion of the late war, for the great degree of tranquility, union, and plenty, which we have since enjoyed, for the peaceable and rational manner in which we have been enabled to establish constitutions of government for our safety and happiness, and particularly the national One now lately instituted, of the civil and religious liberty with which we are blessed, and the means we have to acquiring and diffusing useful knowledge and in general for all the great and various favors which He hath been pleased to confer upon us.

And also that we may then unite in most humble offering our prayers and supplications 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 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 unto us) and to bless them with good government, 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 know to be best.
