text: I'm well aware that some of the more notable founders were only Christians by name but the broader society was Christian as were many of those who fought in the revolution. Washington himself stated "It is impossible to rightly govern the world without God and Bible." You're correct that the constitution is supreme law of the land. However without the context of the other founding documents such as the Federalist papers, the Declaration of Independence which is the foundation of our republic, and  other writings of the founding fathers you lose all context.  The same reason why a lot of leftists like think the Second Amendment is all about deer hunting and government regulated militias which they think means National Guard.
