That I disagree with. It is true that Government is mostly a necessity because of The Fall, but it's clear to me God always intended hierarchies of authority. At the very least human biology argues for it in the form of the family. I would say rather that society's right to censure or punish defaulters through the auspices of government and its laws is the specific result and effect of The Fall on natural authority.
Hierarchies of authority does not contradict the notion that all are equal and that resources can and should be shared equally among all. Marxism is very Christian, but Christian behavior is not possible this side of paradise, if for no other reason than we insist we know the best ways to distribute wealth rather than being willing to listen to G-d's Word on the subject.
Shalom.
