Let common sense rule.
Every servant serves a master. He who serves himself is no servant at all. Doesn’t he make himself his own domain; King and the subjects over which he rules. Can anyone say “folly”? And no servant is allowed to serve two masters, such a man will not serve either one with integrity.
We are servants to the one we obey. Fidelity is the target. Either a man serves chaos or seeks, with all he has, to serve purity.
