Olive,
Here is what I came up for as the paladin codes for my game. They are half-stolen form various elements. Some of those elements being posters on this board .
Anyway, here you go:
1. Servitude – Serve the greater good. Always venerate tradition, and respect authority. Go the extra mile; do more than you are required to do, and do so cheerfully. Keep alert for the chance to do a good deed. Only those who have learned to serve are fit to lead others.
2. Charity – The world can be hard, and no man can hope to survive it alone. By helping others you make the world a better place. The helpless need someone to act on their behalf: The weak need strength. The destitute require hospitality and access to the excess of the community. Provide these things for those in need.
3. Courage – You must be ready to make sacrifices to serve the higher order of good and law. You must know when to choose the more difficult path. It is better to put yourself at a disadvantage than risk performing an evil act. Stupidity often masquerades as courage, but this is a waste of resources, and it serves no one. True courage is demonstrated when one stands by their convictions, even when it is difficult.
4. Defense – It is your duty to protect your country, the common man, your religion and the religions of those who promote good (if not always law and order) – even those that may not deserve such protection. The willingly evil or tyrannical have, by their deeds, forfeited their right for your protection. One must be willing to sacrifice everything to defend their charges.
5. Faith – Horrible things happen to even the most just and valorous. It is those that continue to hold true to the tenants of good and law in hard times that demonstrate true strength. Be a pillar of piety. It is your faith that will provide you the might needed to endure hardships and overcome evil. Your example will give others hope in dark times.
6. Justice – The implementation of a code of law is all that keeps anarchy at bay. True justice protects nobles and commoners alike, and all but the most vile humans and demi-humans are entitled to its protection. Demonstrate the justice that laws can bring at all opportunities. Offer terms to defeated enemies who are not wholly and unredeemably evil. Accept their surrender and consider them under your protection, for mob justice is no justice at all. Let them go free rather than let them come to harm.
7. Integrity – When you give your word, keep it. Your integrity is worth more than your reputation, possessions, or life itself. Be careful to whom you give your word; ensure that it cannot be twisted to evil ends. Choose your companions and patrons wisely. You are entrusting them with your honor. Do not cooperate in evil actions. Your silence or negligence may be the cooperation needed for evil to flourish.
8. Combat – Keep you arm strong and your aim steady. Seek out evil and destroy it before it can harm the innocent. War made in the proactive defense of good and order is just. War made simply for the sake of slaughter is not. Attempt to use the minimum amount of violence necessary to achieve your goals. Mindless slaughter is a waste of resources and leads to evil and chaos. With opponents that are wholly corrupt, however, total destruction may constitute the minimum amount of violence required.
9. Judgment – There will be times when one or more of the above codes will conflict with each other, and when the right and good decision is not clear. That is why it is important to never act rashly. Only act after due consideration. When all options appear equal it is better to err on the side of mercy. Evil acts can never achieve a worthy purpose. Consider carefully what evil might result from an apparently good action, and if there is not a better way.
