Historians, however, have disputed the extent to which the Pilgrims can be counted as among America's founding fathers.
"This is one little pocket of colonial America," says John Fea of Messiah College in Mechanicsburg, Penn. He has written widely on America's early religious history.
"It's hard to make the same argument if you're studying Virginia or Pennsylvania or the Carolinas or Georgia," Fea says. "We've taken that New England model and extrapolated from it over the last 200 or 300 years into some kind of view of the nation as a whole."
Fea notes the absence of any reference to the Bible in either the Declaration of Independence or the U.S. Constitution.
"There are a lot of arguments that say, 'This was just in the air. The Bible would have influenced their construction, even though it's never mentioned,'" he says. "But as a historian, I need a smoking gun. Maybe they left it out because they deliberately wanted to leave it out."
