“In essence, if we are ever ordered by a government authority to personally violate and sin — violate God’s law and sin — if we’re ordered to stop preaching the Gospel, if we’re ordered to perform a same-sex marriage as someone presiding over it, we are called to ignore that. We cannot abide by that because government is compelling us to sin. So when those two come into conflict, God’s rules always win.” ~ Marco Rubio 11/23/2015.

Well, so much for his Presidential aspirations. The United States has a Constitution as its founding document, and any bill passed by our Legislative Branch and signed into law by our Executive Branch must be deemed Constitutional. That’s the role of the Judicial Branch. There is no mention of any god in the Constitution, and presumably Rubio is referring to the Biblical God Yahweh. While Yahweh allegedly telepathically communicated rules to Moses for Israel to follow, they have nothing to do with the United States. The Constitution specifically prohibits the government from establishing any law pertaining to religion–any religion–so Rubio’s assertion that American citizens can violate any law they please because Yahweh, is just factually and legally incorrect.

Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof. – US Constitution

There are many Supreme Court cases dealing with the issue of government entanglement in religion. I cannot find one specific to Rubio’s point though, so it will be interesting to see in what way a legal challenge can be brought about to test his assertion: That an American can refuse to follow a law because it is deemed to be contrary to some invisible deity’s alleged law. But until that day, what Rubio is asserting is in direct contradiction with the Constitution of the United States, and as such, would prevent him from taking the oath of office:

I do solemnly swear (or affirm) that I will faithfully execute the Office of President of the United States, and will to the best of my Ability, preserve, protect and defend the Constitution of the United States.
