One last quote on the meaning of the Declaration of Independence, this time from Abraham Lincoln, responding to a speech by Stephen Douglas, on July 10, 1858. Noting that some Americans are descended from the patriots who fought the Revolution—as I am—he wonders whether those who are not so descended can feel the same attachment to America. Lincoln makes this argument:

“But after we have done all this we have not yet reached the whole. There is something else connected with it. We have besides these men—descended by blood from our ancestors—among us perhaps half our people who are not descendants at all of these men, they are men who have come from Europe—German, Irish, French and Scandinavian—men that have come from Europe themselves, or whose ancestors have come hither and settled here, finding themselves our equals in all things. If they look back through this history to trace their connection with those days by blood, they find they have none, they cannot carry themselves back into that glorious epoch and make themselves feel that they are part of us, but when they look through that old Declaration of Independence they find that those old men say that ‘We hold these truths to be self-evident, that all men are created equal,’ and then they feel that that moral sentiment taught in that day evidences their relation to those men, that it is the father of all moral principle in them, and that they have a right to claim it as though they were blood of the blood, and flesh of the flesh of the men who wrote that Declaration [loud and long continued applause], and so they are. That is the electric cord in that Declaration that links the hearts of patriotic and liberty-loving men together, that will link those patriotic hearts as long as the love of freedom exists in the minds of men throughout the world. [Applause.]”

What unites—or should unite—Americans as Americans is moral principle, not race or ethnicity. And the prologue of the Declaration states the American creed … as well as our theory of government.
