Puritanism in American Life
Puritanism gave Americans a sense of history as a progressive drama under the direction of God, in which they played a role akin to, if not prophetically aligned with, that of the Old Testament Jews as a new chosen people.
Perhaps most important, as Max Weber profoundly understood, was the strength of Puritanism as a way of coping with the contradictory requirements of Christian ethics in a world on the verge of modernity. It supplied ethics that somehow balanced charity and self-discipline. It counseled moderation within psychology that saw worldly prosperity as a sign of divine favor. Such ethics were particularly urgent in a New World where opportunity was rich, but the source of moral authority was obscure.
By the beginning of the 18th century, Puritanism had both declined and shown its tenacity. Though “the New England Way” evolved into a relatively minor system of organizing religious experience within the broader American scene, its central themes recur in the related religious communities of Quakers, Baptists, Presbyterians, Methodists and a whole range of evangelical Protestants.
More recently, the word “Puritan” has once again become a pejorative epithet, meaning prudish, constricted and cold–as in H. L. Mencken’s famous remark that a Puritan is one who suspects “somewhere someone is having a good time.”
Puritanism, however, had a more significant persistence in American life than as the religion of black-frocked caricatures. It survived, perhaps most conspicuously, in the secular form of self-reliance, moral rigor and political localism that became, by the Age of Enlightenment, virtually the definition of Americanism.
