Human Law is, in Thomism, a rational ordinance of the civil common good, derived from the eternal and natural law by particular determination, and binding in conscience insofar as it is just.
Ordinance of reason for the common good
ST I–II q.90 defines law as an ordinance of reason for the common good, made by him who has care of the community, and promulgated. Human Law is that definition applied to the civil community. It is not raw will. A command that is not reasonable, not ordered to the common good, or not from lawful authority fails as law even if it is printed and enforced. The Catechism's teaching on authority and the common good is the doctrinal counterpart.[1]
Human law cannot invent the good. It determines what the Eternal Law and natural law leave undetermined: measures, offices, penalties, roads, taxes, and many forms of justice. That is why just statutes bind in conscience. They participate the higher measure. Divine Law remains another order, directed to the supernatural end, and is not replaced by the city.
Determination, not deduction of every clause
Some civil norms are conclusions from natural law, such as prohibitions of murder. Others are determinations, such as which side of the road to drive. Both can be true law. Treating every statute as a revealed theorem is a category error. Treating none as morally binding is another.
Unjust law
A statute contrary to the divine or natural law is a perversion of law and does not bind as law. If it commands sin, it must be refused. If it is unjust in burden or process but does not command sin, Aquinas allows that one may sometimes yield for the sake of order. That casuistry is theology. The Church's later social teaching on unjust regimes, conscientious refusal, and the rights of persons belongs on the same line without making every medieval example current policy.[2]
Human law also cannot reach the interior act as such, nor confer sanctifying grace. It can command outward acts, teach, deter, and habituate. Habitus of civic virtue can be encouraged by good law. Infused virtue cannot be legislated. The Natural and Supernatural Orders again prevent the state from pretending to be the Church, and the Church from pretending to be the police of every temporal arrangement.[3]
Change, custom, and equity
Because human law is particular, it can and sometimes must change as circumstances change, provided the change does not shatter the custom that itself belongs to the common good. Equity, epikeia, is the higher justice that fulfills the legislator's intention when a general wording would harm in a particular case. These are Thomistic tools of prudence, not loopholes against the moral law. Veritatis Splendor forbids using such tools to dissolve intrinsically evil acts.[4]
Custom can obtain the force of law when it is reasonable and received. It cannot legalize what natural law forbids. The Four Causes appear here analogically: the common good as end, the community's reason as form, the promulgating authority as agent, and the matter of human acts as what is ordered. The analogy is pedagogical, not a defined ontology of the state.
Status
Doctrine: authority is from God for the common good; civil law is not the source of good and evil; unjust commands to sin do not bind; the Church is not a department of the state. Synthesis: the exact definition in q.90, the treatise on change and custom, and many medieval illustrations. Catholic social teaching develops the same principles without being a reprint of the Summa's political asides.[5]
The concept trains citizens and rulers together. Law is a moral act. Obedience is a moral act. Both are measured from above. This Thomistic synthesis of Human Law is that measurement applied to the city, with a severity against tyranny and a respect for true political reason that remains under God.[6]
