21. The role of law is not to record what is done, hut to help in promoting improvement. It is at all times the task of the State to preserve each person's rights and to protect the weakest. In order to do so the State will have to right many wrongs. The law is not obliged to sanction everything, but it cannot act contrary to a law which is deeper and more majestic than any human law: the natural law engraved in men's hearts by the Creator as a norm which reason clarifies and strives to formulate properly, and which one must always struggle to understand better, but which it is always wrong to contradict. Human law can abstain from punishment, but it cannot declare to be right what would be opposed to the natural law, for this opposition suffices to give the assurance that a law is not a law at all.
