...not a single traditional Christian can be found among the leading names of the American Revolution. Neither George Washington, nor John Adams, nor Thomas Jefferson, nor Benjamin Franklin, nor Alexander Hamilton professed traditional Christian belief, although most of them expressed an idiosyncratic personal faith of some sort. The same applies to Abraham Lincoln, who attended no church, although his later speeches are hewn out of the same rock as the Scriptures...

...one can trace no obvious connection between the religion of America's founders and today's American evangelicals.
