Article VI of the United States Constitution states that any debts that the United States held before the creation of the Constitution, or during the Articles of Confederation, remain valid under the United States Constitution.
It also states that government officials running for United States government offices cannot be required to undergo a religious test in order to run for office.
Article VI also contains the Supremacy Clause, or clause II, which states that the Constitution and any laws or treaties enacted under its rule are the supreme law of the land. State laws and court rulings are bound by federal law, meaning that if there is a conflict between the state and federal government, the federal government's rulings and laws override those of the state.
The third clause of Article VI states that government officials are bound by oath to the Constitution, and that Congress may decide the form of that oath, but that no government official can be required to take a religious test.
