And whereas the said ordinance prescribes to the people of South Carolina a course of conduct in direct violation of their duty as citizens of the United States, contrary to the laws of their country, subversive of its Constitution, and having for its object the instruction of the Union—that Union, which, coeval with our political existence.

Jackson lays the political smackdown here. He's calling the Nullies bad citizens, constitution-haters, and the bringers of national destruction. Harsh. But he sees this as a potential Union-destroying crisis.

I consider, then, the power to annul a law of the United States, assumed by one State, incompatible with the existence of the Union, contradicted expressly by the letter of the Constitution, unauthorized by its spirit, inconsistent with every principle on which It was founded, and destructive of the great object for which it was formed. (13)
Jackson wasn't much one for shades of gray in his public statements.
Quote #3
This objection may be made with truth to every law that has been or can be passed. The wisdom of man never yet contrived a system of taxation that would operate with perfect equality. (16)
