„Romans 13 shows the characteristics of true governance: its magistrates affirm and encourage good behavior, but discourage evil actions (Romans 13:3); true authority is a minister of God for good, and enforces justice (Romans 13:4); true authority protects the innocent and prosecutes the evil (Romans 13:4).
The people are to be subject to such legitimate government. However: Any governing system that comes out from under true authority is subject to legitimate resistance, revolution and replacement.”
