While these works shed much light on the actual lives of Puritans and the ideas they held, laymen may still wonder about the importance of the Puritans to current life. George McKenna attempted to answer this question in his 2007 work The Puritan Origins of American Patriotism. McKenna’s work tied a thread throughout American history that went back into early days of the Puritan experiment in New England. He used Miller’s errand into the wilderness to show that Americans still believe that they have a certain mission in the world, which is tied to the idea of Americanism. McKenna argued:
The very definition of America is thus bound up with the biblical paradigm of a people, like the ancient Hebrews, given a holy mission in a new land. It runs through the rhetoric of America’s presidents, and we can find it almost at random in their speeches, whether it was Lincoln depicting Americans as an “almost chosen people,” Franklin Roosevelt talking about an American generation’s “rendezvous with destiny,” Reagan calling America “a shining city on a hill,” or George W. Bush declaring that “America is a nation with a mission, and that mission comes from our most basic beliefs.” We can trace this providentialism directly back to the Puritans of the seventeenth century. They managed to envisage an America long before there was a United States of America. America is a work of the imagination as much as it is a juridical entity, and it was their imagination that played the seminal role in creating it. “The myth of America,” writes Sacvan Bercovitch, “is the creation of the New England Way.”
McKenna then went on to tie this thread together from New England through various reform movements or calls back to American values. For example, when dealing with the Populists and Progressives, he pointed out that some of the reforms (like prohibition) that these groups encouraged are now considered conservative, while others (such as encouragement of labor reform) fall under the liberal rubric. McKenna maintained that these reforms were a part of the social gospel, and that the same people supported these progressive reforms with a mainly religious purpose.
McKenna did not only use examples from the Progressive Era. He looked throughout American history and saw a Puritan thread throughout. He saw Patriotism and the reform ethos of the Puritans as inextricably linked. So, whether you agree with the Puritans from a religious standpoint or just think (erroneously) that they wore funny clothes and hated all manner of fun, their goal of a godly reformation has greatly impacted American history.
