Let us hear the matter from someone a little more contemporary with the Convention:
"On examining the first relation, it appears, on one hand, that the Constitution is to be founded on the assent and ratification of the people of America, given by deputies elected for the special purpose; but, on the other, that this assent and ratification is to be given by the people, not as individuals composing one entire nation, but as composing the distinct and independent States to which they respectively belong. It is to be the assent and ratification of the several States, derived from the supreme authority in each State, the authority of the people themselves. The act, therefore, establishingthe Constitution, will not be a national, but a federal act.
"That it will be a federal and not a national act, as these terms are understood by the objectors; the act of the people, as forming so many independent States, not as forming one aggregate nation, is obvious from this single consideration, that it is to result neither from the decision of a majority of the people of the Union, nor from that of a majority of the States. It must result from the unanimous assent of the several States that are parties to it, differing no otherwise from their ordinary assent than in its being expressed, not by the legislative authority, but by that of the people themselves. Were the people regarded in this transaction as forming one nation, the will of the majority of the whole people of the United States would bind the minority, in the same manner as the majority in each State must bind the minority; and the will of the majority must be determined either by a comparison of the individual votes, or by considering the will of the majority of the States as evidence of the will of a majority of the people of the United States. Neither of these rules have been adopted. Each State, in ratifying the Constitution, is considered as a sovereign body, independent of all others, and only to be bound by its own voluntary act. In this relation, then, the new Constitution will, if established, be a federal, and not a national constitution." [James Madison, Federalist Paper No. 39, in Bailey, Bill, "The Complete Federalist Papers." The New Federalist Papers Project, p.178]
The last two underlined clauses expose Lincoln's BIG LIE!
This explains that each state was, and is a sovereign power.
"Will it be said that the fundamental principles of the Confederation were not within the purview of the convention, and ought not to have been varied? I ask, What are these principles? Do they require that, in the establishment of the Constitution, the States should be regarded as distinct and independent sovereigns? They are so regarded by the Constitution proposed."
[James Madison, Federalist Paper No. 40, p.183]
The general government is not sovereign, but is merely an agent of the several sovereign states. The powers given by the several states to the general government are both FEW, and DEFINED, as Madison also explained:
"The powers delegated by the proposed Constitution to the federal government, are few and defined. Those which are to remain in the State governments are numerous and indefinite. The former will be exercised principally on external objects, as war, peace, negotiation, and foreign commerce; with which last the power of taxation will, for the most part, be connected. The powers reserved to the several States will extend to all the objects which, in the ordinary course of affairs, concern the lives, liberties, and properties of the people, and the internal order, improvement, and prosperity of the State." [James Madison, Federalist No. 45, pp.214-215]
Secession is not a delegated and defined power of the general government; therefore the three states in question -- NY, RI, and VA -- were simply restating a power they already possess.

Nevertheless, signing statements carry no weight of law.
