Leaving aside the religious aspect of the CoC which are probably going to be controversial the other rules are actually fairly common sense. A few that caught my eye:
> Do not give way to anger.
> Do not nurse a grudge.
> Do not entertain deceit in your heart.
> Do not give a false peace.
> Do not swear, for fear of perjuring yourself.
> Utter only truth from heart and mouth.
> Do not return evil for evil.
> Be not a grumbler.
> Be not a detractor.
> Hate no one.
> Be not jealous, nor harbor envy.
> Do not love quarreling.
> Shun arrogance.
> Respect your seniors.
> Love your juniors.
> Make peace with your adversary before the sun sets.
Good rules to live by IMO.
