JOAN: "I tell thee that the land is thine to […] keep God's peace in […] The very clay of France will become holy […] the rebel dukes will be rebels against God." (2.175)
Joan is basically calling for the dismantling of the entire feudal system. She wants all he power to go to the King and be taken from all the lower nobility.

CAUCHON: "The Catholic Church knows only one realm, and that is the realm of Christ's kingdom. Divide that kingdom into nations, and you dethrone Christ." (4.120)
It's interesting that, while Joan uses her version of Christianity to support her Nationalistic views, Cauchon uses his version to attack them.

WARWICK: "Well, if you will burn the Protestant, I will burn the Nationalist." (4.121)
This quote is the one of the best summations in the play of why Joan is burnt. The Church fears her Protestantism because it challenges their power; the nobles fear her Nationalism for the same reason.
