This is one of the first printed copies of The First Prayer in Congress made available to the public and was published by H. V. Wright, Washington City. He notes, "In "Thatcher's Military Journal," under date of December 1777, is found a note containing the identical "First Prayer in Congress," made b the Rev. Jacob Duche, a gentleman of great eloquence, Here it is - a historical curiosity."
The prayer was published in Thatcher's Journal in 1823. You can read more on this historical document at The Foundation Forum.
Historians of the 20th Century differ on the actual date and year it was read, but the prayer is grounded in the birth of our nation and as fitting for our stressful time as at any previous time in our country's struggles.
Enjoy and have a safe and happy Fourth of July!
