And there hasn’t been any material change since the 18th century. There were fierce debates over policies back in the 1700s, including some of the same debates we’re having today, like over tariffs. The federal government already had thousands of employees even during Jefferson’s time in 1802. Nobody imagined that those employees would have anything more than a ministerial role carrying out the agenda of the elected President.
And yes, the only way to describe what you’re seeing among federal employees today is a religion. I’m in DC. Some people—and again to be clear it’s a minority—are literally crying over changes in government policies related to immigration, defriending people based on who they voted for, etc. These are not detached professionals who deserve the public trust. They’re religious nuts who believe they have the moral high ground and that gives them the right to override the constitutional design.
You're clearly American. The American founding fathers wanted to avoid tyranny of the majority. That is clear. Civil servants pushing back is exactly that! No, it's not documented in the Federalist papers but the world is a lot more complicated than the 18th century.
