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 signal 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, for the civil and religious liberty with which we are blessed, and the means we have of acquiring and diffusing useful knowledge and in general for all the great and various favors which he hath been pleased to confer upon us.
Lincoln's proclamation took a more somber tone:
UPDATE: The full text of all Presidential Thanksgiving Proclamations are posted at Pilgrim Hall Museum. Thanks to Joseph M. Knippenberg for this lead, and see his discussion of Thanksgiving Procalmations here and here.And I recommend to them that while offering up the ascriptions justly due to Him for such singular deliverances and blessings, they do also, with humble penitence for our national perverseness and disobedience, commend to his tender care all those who have become widows, orphans, mourners or sufferers in the lamentable civil strife in which we are unavoidably engaged, and fervently implore the interposition of the Almighty Hand to heal the wounds of the nation and to restore it as soon as may be consistent with the Divine purposes to the full enjoyment of peace, harmony, tranquility and Union.
