Timely, as five Catholics might take a seat on the Highest Bench:
Pope Benedict XVI emphasized the "respect for the universal moral law" as he met on November 12 with a new ambassador from the United States.
As he accepted the diplomatic credentials of Francis Rooney, the Holy Father said that the "rich patrimony of values and principles" derived from natural law is the best guarantee of human rights and, if followed by national leaders, can create "the conditions of justice and peace in which individuals and communities can flourish." The Pope explained that while the Holy See cannot become involved in partisan political debates, the Church will always work to uphold the natural law.
Link.
Of course, when partisan politics attempts to shred the natural law, then the Church will get involved. The Church-State Separationists scream "foul," but if politics is going to tread in the area of morals (and at some points it must), issues of natural law will get raised. When that happens, who says secular politics must be the only voice in the public square? The Constitution and Bill of Rights don't.
