The court’s opinion that male-female “marriage” is “unconstitutional” is absurd because it is contrary to God’s Law (God Almighty Himself has defined marriage to be between one man and one woman) which is the very basis of the Supreme Law of the Land of our nation, the U.S. Constitution!
(1) The US Constitution is indeed the "Supreme Law of the Land of our nation". It actually says so in Article VI. "Supreme" means "the highest there is". There's no "super-law" that overrides the Constitution. If God wants to override the Constitution, that's His lookout, not the court's.
(2) It is what it is. If we want "God's Law" written into it, it must be written down in the document itself. Only dictatorships have unwritten laws left up to the police and the courts to enforce as they like.
(3) What is "God's Law"? There are thousands of different opinions on the subject. Who says your opinion is the right one?
(4) If by "God's Law" you mean the Bible, then "God Almighty Himself" certainly has not "defined marriage to be between one man and one woman". Actually, there are a whole bunch of definitions, depending on which part you read.
(5) There's no indication that the framers of the Constitution ever intended "God's Law" to be the basis for the Constitution. The fact that the First Amendment forbids the government to stick its nose into religion, either for or against, and Article VI forbids religious tests for public office suggests that the opposite is true.
To quote Dr. Martin Luther King who quoted St. Thomas Aquinas: Any law contrary to God’s Law is no law at all!
Yes, I believe Al Qaeda says something like the same thing. They probably have a different opinion about God's Law, though (see (3) above).
