Romans 13, in my opinion, is the Achilles heel for the argument that the modern bible is the literal "Word of God" cover to cover. If you follow the teachings and example of Yeshua, then Paul's opinions in Romans(& that is all that they actually are) become void. Before his conversion, Paul was a Roman assassin and mass murderer, hunting Christians for the Empire. I doubt he lost his statist tendencies entirely and that reflects here.
