It is divided into Mosaic (Old Testament) Law and New Law (New Testament). Aquinas uses the term "natural law" to refer to morality, or the moral law. Divine Law: Eternal law as it appears to humans, especially through revelation, is derived from eternal law. A law must be made and promulgated by those in charge of the community. I.e., divine law is eternal law when it appears to humans as divine commands, (through scripture). Aquinas thinks that everything has a purpose and follows a plan. And because the Eternal Law is part of God’s mind then it has always, and will always, exist. Aquinas bases his doctine on the natural law, as one would expect, on his understanding of God and His relation to His creation. When speaking of the Mosaic Law, Aquinas is thinking mainly of the 10 Commandments. In speaking of the new law … He, like Chapter 10). Aquinas establishes four types of laws: eternal law, natural law, human law, and divine law. He grounds his theory of natural law in the notion of an eternal law (in God). In asking whether there is an eternal law, he… It’s moral law— the law of Nature. For there is a law of the “fomes,” as stated above (Question 91, Article 6), which is not derived from that Divine law which is the eternal law, since thereunto pertains the “prudence of the flesh,” of which the Apostle [Paul] says (Romans 8:7), that “it cannot be subject to the law of God.” Therefore not every law is derived from the eternal law. He sees law as a rational attempt to guide action. By “Eternal Law’” Aquinas means God’s rational purpose and plan for all things. A law is a prescription that we act or not act; it may also exist in us as an inclination to act in certain ways. The Eternal Law is not simply something that God decided at some point to write. Eternal law “Gods providence rules the world…his reason evidently governs the entire community in the universe.” (91.1) Aquinas believes that eternal law is all god's doing. According to Thomas Aquinas, who defined it, it’s a Christian religious concept that aggregates those laws that govern the nature of an eternal universe. Eternal law is God’s “eternal plan” in which he controls the course of the universe based on his own perspective (Aquinas 18). Natural law is the participation in the eternal law by rational creators. St. Thomas Aquinas on the Natural Law.
