From the Heritage Foundation:
While we have never been and should not try to become a nation defined by a particular or official religious denomination, we must never forget that, as the Supreme Court said in 1952 (and reiterated in 1963, and again in 1984), “We are a religious people whose institutions presuppose a Supreme Being.”
The health and strength of liberty depend on the principles, standards, and morals shared by nearly all religions. What the “separation of church and state” does is liberate America’s religions–in respect to their moral forms and teachings–to exercise unprecedented influence over private and public opinion by shaping citizens’ mores, cultivating their virtues, and in general, providing a pure and independent source of moral reasoning and authority. This is what Alexis de Tocqueville meant when he observed that even though religion “never mixes directly in the government of society,” it nevertheless determines the “habits of the heart” and is “the first of their political institutions.”
