More than two centuries after its adoption, the First Amendment remains one of the bedrock tenants of American values; most state constitutions (including New Jersey’s) have equivalent free exercise provisions. But like all of the Constitution and Bill of Rights, modern courts determine how it should be interpreted and applied to current disputes.
