Resolved, That the several States composing, the United States of America, are not united on the principle of unlimited submission to their general government; but that, by a compact under the style and title of a Constitution for the United States, and of amendments thereto, they constituted a general government for special purposes — delegated to that government certain definite powers, reserving, each State to itself, the residuary mass of right to their own self-government

That’s the Kentucky Resolution of 1798, passed in response to the anti-1st Amendment Alien and Sedition Act passed by the Federalists. It’s asserting states rights, or the anti-Federalist position against greater federal power favored by the Federalists. It was written by Thomas Jefferson. A similar Resolution in Virginia was authored by James Madison, who switched from the Federalists to the other side.
