The guarantee of the free exercise of religion, which I will call religious freedom, is the first expression in the First Amendment to the United States Constitution. As noted by many, this “pre-eminent place” identifies freedom of religion as “a cornerstone of American democracy.” The American colonies were originally settled by people who, for the most part, had come to this continent to be able to practice their religious faith without persecution, and their successors deliberately placed religious freedom first in the nation’s Bill of Rights. So it is that our national law formally declares: “The right to freedom of religion undergirds the very origin and existence of the United States.”
