and to clarify my view here:Takkanot
Jesus might have specifically said "resist unlawful decree, Mosaicly they are not binding on you" or
He might have been saying "they sit in Moses' seat, so All that they tell you to do, then do (but understand that unlawful decrees are not considered binding on you by God, they are just orders of men)" I'm not positive on this issue.
I don't see Him as advocating violent insurrection, even to Jewish leadership corruption.
He did say "if someone compels you to go one mile, go two miles" even though a Roman soldier seeking your help was only allowed to compel for the first mile, to my understanding. You could still know that forcing for two was not Roman lawful.
