How Jefferson and Monroe felt about the power and scope of the Federal government, as prescribed by the Constitution, can be found in the Kentucky Resolution of 1798 and the Virginia Resolution of 1798.

The following resolutions were proposed to the Kentucky Legislature, and this version was adopted on November 10, 1798, as a protest against the Alien and Sedition Acts passed by Congress. They were authored by Thomas Jefferson, but he did not make public the fact until years later. This represents one of the clearest expressions of his views on how the Constitution was supposed to be interpreted.
The Kentucky Resolutions of 1798
1. 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; and that whensoever the general government assumes undelegated powers, its acts are unauthoritative, void, and of no force: that to this compact each State acceded as a State, and is an integral part, its co-States forming, as to itself, the other party: that the government created by this compact was not made the exclusive or final judge of the extent of the powers delegated to itself; since that would have made its discretion, and not the Constitution, the measure of its powers; but that, as in all other cases of compact among powers having no common judge, each party has an equal right to judge for itself, as well of infractions as of the mode and measure of redress.
2. Resolved, That the Constitution of the United States, having delegated to Congress a power to punish treason, counterfeiting the securities and current coin of the United States, piracies, and felonies committed on the high seas, and offenses against the law of nations, and no other crimes, whatsoever; and it being true as a general principle, and one of the amendments to the Constitution having also declared, that “the powers not delegated to the United States by the Constitution, not prohibited by it to the States, are reserved to the States respectively, or to the people,” therefore the act of Congress, passed on the 14th day of July, 1798, and intituled “An Act in addition to the act intituled An Act for the punishment of certain crimes against the United States,” as also the act passed by them on the — day of June, 1798, intituled “An Act to punish frauds committed on the bank of the United States,” (and all their other acts which assume to create, define, or punish crimes, other than those so enumerated in the Constitution,) are altogether void, and of no force; and that the power to create, define, and punish such other crimes is reserved, and, of right, appertains solely and exclusively to the respective States, each within its own territory.
3. Resolved, That it is true as a general principle, and is also expressly declared by one of the amendments to the Constitutions, that “the powers not delegated to the United States by the Constitution, our prohibited by it to the States, are reserved to the States respectively, or to the people”; and that no power over the freedom of religion, freedom of speech, or freedom of the press being delegated to the United States by the Constitution, nor prohibited by it to the States, all lawful powers respecting the same did of right remain, and were reserved to the States or the people: that thus was manifested their determination to retain to themselves the right of judging how far the licentiousness of speech and of the press may be abridged without lessening their useful freedom, and how far those abuses which cannot be separated from their use should be tolerated, rather than the use be destroyed. And thus also they guarded against all abridgment by the United States of the freedom of religious opinions and exercises, and retained to themselves the right of protecting the same, as this State, by a law passed on the general demand of its citizens, had already protected them from all human restraint or interference. And that in addition to this general principle and express declaration, another and more special provision has been made by one of the amendments to the Constitution, which expressly declares, that “Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof, or abridging the freedom of speech or of the press”: thereby guarding in the same sentence, and under the same words, the freedom of religion, of speech, and of the press: insomuch, that whatever violated either, throws down the sanctuary which covers the others, arid that libels, falsehood, and defamation, equally with heresy and false religion, are withheld from the cognizance of federal tribunals. That, therefore, the act of Congress of the United States, passed on the 14th day of July, 1798, intituled “An Act in addition to the act intituled An Act for the punishment of certain crimes against the United States,” which does abridge the freedom of the press, is not law, but is altogether void, and of no force.
