"Jefferson's Danbury letter has been cited favorably by the Supreme Court many times. In its 1879 Reynolds vs. U.S. decision the high court said Jefferson's observations 'may be accepted almost as an authoritative declaration of the scope and effect of the [First] Amendment.' In the court's 1947 Everson v. Board of Education decision, Justice Hugo Black wrote, 'In the words of Thomas Jefferson, the clause against establishment of religion by law was intended to erect a wall of separation between church and state.' It is only in recent times that separation has come under attack by judges in the federal court system who oppose separation of church and state."
