First Prayer in Congress, September 1774, "Establishment Clause must be interpreted by reference to historical practices & understandings"-Supreme Court, Galloway - American Minute with Bill Federer
In the Supreme Court case of Town of Greece, NY, v. Galloway et al, Justice Kennedy wrote in the decision, May 5, 2014:
"The first prayer delivered to the Continental Congress by the Rev. Jacob Duché on Sept. 7, 1774, provides an example: '...All this we ask in the name and through the merits of Jesus Christ, Thy Son and our Saviour, Amen' ... (W. Federer, America’s God and Country 137, 2000).
From the earliest days of the Nation, these invocations have been addressed to assemblies ...
Our tradition assumes that adult citizens ... can tolerate and perhaps appreciate a ceremonial prayer delivered by a person of a different faith."
