“The term “citizen,” (natural/original common law) as understood in our law, is precisely analogous (Similar in function but not in structure(meaning) and evolutionary origin (jus commune/natural/original common law v. jura corona, or lex prerogativa/feudal/statutory law)) to the term "subject" (jura corona, or lex prerogativa/feudal/statutory law) in the common law, and the change of phrase has entirely resulted from the change of government.”
Thus when the founders & framers changed the form of government, they also changed the form of citizenship. Form being the meaning of the term not the function. It was how an individual became tied to the political state.
We went from subjects to citizens. As cited in WKA, “The sovereignty has been transferred from one man to the collective body of the people, and he who before as a ’subject of the king’ is now ‘a citizen of the State.”
So...what is your point?
