Massachusetts Governor John Hancock’s Thanksgiving Proclamation, 1791

In consideration of the many undeserved Blessings conferred upon us by GOD, the Father of all Mercies, it becomes us not only in our private and usual devotion, to express our obligations to Him, as well as our dependence upon Him; but also specially to set apart a Day to be employed for this great and important Purpose:
I have therefore thought fit to appoint, and the advice and consent of the Council, do hereby accordingly appoint. Thursday, the seventeenth day of November next, to be observed as a Day of Public THANKSGIVING and PRAISE, throughout this Commonwealth: – Hereby calling upon Ministers and People of every denomination to assemble on the said Day – and in the name of the Great Mediator, devoutly and sincerely offer to Almighty God, the gratitude of our Hearts' for all his goodness towards us; more especially in that HE has been pleased to continue to us so great a measure of Health – to cause the Earth plentifully to yield her increase, so that we are supplied with the Necessaries, and the Comforts of Life – to prosper our Merchandise and Fishery – And above all, not only to continue to us the enjoyment of our civil Rights and Liberties; but the great and most important Blessing, the Gospel of Jesus Christ.
