Subordination is significantly different from unconditional obedience. Was Christ “obedient” to Rome? He was killed by Rome. Romans 13 is not about “blind obedience to the state.” If that was the case, the Christians would all have been worshiping Caesar. Paul is rejecting any notion of violent revolution. Paul has no illusions about Rome being a servant of God, though he does use corrupt nations for his purposes as they remain under his judgment.
