Samuel Langdon (1723-1797), the president of Harvard University, was a member of the New Hampshire Convention to ratify the U.S. Constitution in 1794, as well as an original member of the American Academy of Arts and Sciences.  In May of 1775, Harvard President Samuel Langdon was invited to give an address to the Provincial Congress of Massachusetts.  In it he stated:

"We have rebelled against God.  We have lost the true spirit of Christianity, though we retain the outward profession and form of it....  By many, the Gospel is corrupted into a superficial system of moral philosophy, little better than ancient Platonism....

"My brethren, let us repent and implore the divine mercy.  Let us amend our ways and our doings, reform everything that has been provoking the Most High, and thus endeavor to obtain the gracious interpositions of providence for our deliverance....

"May the Lord hear us in this day of trouble....  We will rejoice in His salvation, and in the name of our God, we will set up our banners!"  - May 1775, address as Harvard President to the Provincial Congress of Massachusetts.  A.
