The Religious Founding of America

"...Many of the colonies that in 1776 became the United States of America were settled by men and women of deep religious convictions who in the seventeenth century crossed the Atlantic Ocean to practice their faith freely. That the religious intensity of the original settlers would diminish to some extent over time was perhaps to be expected, but new waves of eighteenth century immigrants brought their own religious fervor across the Atlantic and the nation's first major religious revival in the middle of the eighteenth century injected new vigor into American religion. The result was that a religious people rose in rebellion against Great Britain in 1776, and that most American statesmen, when they began to form new governments at the state and national levels, shared the convictions of most of their constituents that religion was, to quote Alexis de Tocqueville's observation, indispensable to the maintenance of republican institutions."
