“I think it is reasonable to say that Jefferson’s purpose here was to establish the right to session based on natural law principles.”
Jefferson contention was: “. . . the laws of nature and of nature’s God entitle them . . .”
And “ . . . they are endowed by their Creator . . .”
Jefferson didn’t claim he was establishing some new right in the DOI, or even advocating something new. Rights, Jefferson argued - even the right of secession comes from God - not from the government or the DOI.
Who said anything about a “new” right or the right of secession coming anywhere but from God? You’re reading stuff into what I’m saying that I’m not saying. I’ve repeatedly said “God-given” and NEVER said government-given or the right emerging from the D of I. Jefferson used the D of I to establish the God-given natural right of secession, among other things.
Jefferson never spoke of a "God-given" right of secession. He (and many other founders) recognized a God-given right of rebellion against tyranny. They also recognized that rebellion comes with consequences and risks.
God never said that all your wishes automatically come true.
