First Amendment of the U.S. Constitution, the first of ten amendments in the so-named Bill of Rights, states "Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof."

William Smith stated, "Religion and liberty must flourish or fall together in America" (Barry).

In 2010, former vice-presidential candidate Sarah Palin was critical of a federal judge who struck down the federal law that had created the National Day of Prayer in 1952 ("AU's Lynn Challenges Sarah Palin"). Palin asserted that the United States must get back to its "Christian roots," which is what the forefathers intended. Sounding like Roger Williams, Rev. Dr. Steve Ohnsman, a pastor at Calvary United Church in Pennsylvania, argued that keeping Church and State separate…
