“Our gathering here today is in testimony of supreme obligation to those who have given most to make and preserve the Nation. They established it upon the dual system of State government and Federal Government, each supreme in its own sphere. But they left to the States the main powers and functions of determining the form and course of society. We have demonstrated in the time of war that under the Constitution we possess an indestructible Union. We must not fail to demonstrate in the time of peace that we are likewise determined to possess and maintain indestructible States. This policy can be greatly advanced by individual observance of the law. It can be strongly supplemented by a vigorous enforcement of the law. The war which established Memorial Day had for its main purpose the enforcement of the Constitution. The peace which followed that war rests upon the universal observance of the Constitution. This Union can only be preserved, the States can only be maintained, under a reign of national, local, and moral law, under the Constitution established by Washington, under the peace provided by Lincoln.”

McCulloch v. Maryland (1819)
Context: [T]he Government of the Union, though limited in its powers, is supreme within its sphere of action. This would seem to result necessarily from its nature. It is the Government of all; its powers are delegated by all; it represents all, and acts for all. Though any one State may be willing to control its operations, no State is willing to allow others to control them. The nation, on those subjects on which it can act, must necessarily bind its component parts. But this question is not left to mere reason; the people have, in express terms, decided it by saying, [p406] "this Constitution, and the laws of the United States, which shall be made in pursuance thereof," "shall be the supreme law of the land," and by requiring that the members of the State legislatures and the officers of the executive and judicial departments of the States shall take the oath of fidelity to it. The Government of the United States, then, though limited in its powers, is supreme, and its laws, when made in pursuance of the Constitution, form the supreme law of the land, "anything in the Constitution or laws of any State to the contrary notwithstanding."

McCulloch v. Maryland (1819)
Context: In America, the powers of sovereignty are divided between the Government of the Union and those of the States. They are each sovereign with respect to the objects committed to it, and neither sovereign with respect to the objects committed to the other. We cannot comprehend that train of reasoning, which would maintain that the extent of power granted by the people is to be ascertained not by the nature and terms of the grant, but by its date. Some State Constitutions were formed before, some since, that of the United States. We cannot believe that their relation to each other is in any degree dependent upon this circumstance. Their respective powers must, we think, be precisely the same as if they had been formed at the same time. Had they been formed at the same time, and had the people conferred on the General Government the power contained in the Constitution, and on the States the whole residuum of power, would it have been asserted that the Government of the Union was not sovereign, with respect to those objects which were intrusted to it, in relation to which its laws were declared to be supreme? If this could not have been asserted, we cannot well comprehend the process of reasoning which maintains that a power appertaining to sovereignty cannot be connected with that vast portion of it which is granted to the General Government, so far as it is calculated to subserve the legitimate objects of that Government.
