Natural law is a system of law based on a close observation of natural order and human nature, from which values, thought by the proponents of this concept to be intrinsic to human nature, can be deduced and applied independently of positive law. According to the theory of law called jusnaturalism, all people have inherent rights, conferred not by act of legislation but by "God, nature, or reason." Natural law theory can also refer to "theories of ethics, theories of politics, theories of civil law, and theories of religious morality."
Theological virtues are virtues associated in Christian theology and philosophy with salvation resulting from the grace of God. Virtues are traits or qualities which dispose one to conduct oneself in a morally good manner. Traditionally the theological virtues have been named Faith, Hope, and Charity (Love). They are coupled with the natural or cardinal virtues and opposed to the seven deadly sins.
The just war theory is a doctrine, also referred to as a tradition, of military ethics that aims to ensure that a war is morally justifiable through a series of criteria, all of which must be met for a war to be considered just. It has been studied by military leaders, theologians, ethicists and policymakers. The criteria are split into two groups: jus ad bellum and jus in bello. The first group of criteria concerns the morality of going to war, and the second group of criteria concerns the moral conduct within war. There have been calls for the inclusion of a third category of just war theory dealing with the morality of post-war settlement and reconstruction. The just war theory postulates the belief that war, while it is terrible but less so with the right conduct, is not always the worst option. Important responsibilities, undesirable outcomes, or preventable atrocities may justify war.
Jus ad bellum, literally "right to war" in Latin, refers to "the conditions under which States may resort to war or to the use of armed force in general". This is distinct from the set of rules that ought to be followed during a war, known as jus in bello, which govern the behavior of parties in an armed conflict.
Thomism is the philosophical and theological school which arose as a legacy of the work and thought of Thomas Aquinas (1225–1274), the Dominican philosopher, theologian, and Doctor of the Church.

Pacem in terris is a papal encyclical issued by Pope John XXIII on 11 April 1963, on the rights and obligations of people and their states, as well as proper interstate relations. It emphasizes human dignity and human equality in endorsing women's rights, nuclear nonproliferation and the United Nations.
The satisfaction theory of atonement is a theory in Catholic theology which holds that Jesus Christ redeemed humanity through making satisfaction for humankind's disobedience through his own supererogatory obedience. The theory draws primarily from the works of Anselm of Canterbury, specifically his Cur Deus Homo. It has been traditionally taught in the Roman Catholic tradition of Western Christianity. Since one of God's characteristics is justice, affronts to that justice must be atoned for. It is thus connected with the legal concept of balancing out an injustice.
The Summa Theologiae or Summa Theologica, often referred to simply as the Summa, is the best-known work of Thomas Aquinas (1225–1274), a scholastic theologian and Doctor of the Church. It is a compendium of all of the main theological teachings of the Catholic Church, intended to be an instructional guide for theology students, including seminarians and the literate laity. Presenting the reasoning for almost all points of Christian theology in the West, topics of the Summa follow the following cycle: God; Creation, Man; Man's purpose; Christ; the Sacraments; and back to God.
The Quinque viæ are five logical arguments for the existence of God summarized by the 13th-century Catholic philosopher and theologian Thomas Aquinas in his book Summa Theologica. They are:
- the argument from "first mover";
- the argument from universal causation;
- the argument from contingency;
- the argument from degree;
- the argument from final cause or ends.
Réginald Marie Garrigou-Lagrange was a French Dominican friar, philosopher and theologian. Garrigou-Lagrange was a neo-Thomist theologian, recognized along with Édouard Hugon and Martin Grabmann as distinguished theologians of the 20th century. As professor at the Pontifical University of Saint Thomas Aquinas, he taught dogmatic and spiritual theology in Rome from 1909 to 1959. There he wrote The Three Ages of the Interior Life in 1938.
Jus post bellum is a concept that deals with the morality of the termination phase of war, including the responsibility to rebuild. The idea has some historical pedigree as a concept in just war theory. In modern times, it has been developed by a number of just war theorists and international lawyers. However, the concept means different things to the contributors in each field. For lawyers, the concept is much less clearly defined, and many have rejected the usefulness of the concept altogether. The concept continues to attract scholarly interest in the field of international humanitarian law.
Thomas Aquinas was an Italian Dominican friar and priest, an influential philosopher and theologian, and a jurist in the tradition of scholasticism from the county of Aquino in the Kingdom of Sicily.
De libero arbitrio voluntatis, often shortened to De libero arbitrio, is a book by Augustine of Hippo which seeks to resolve the problem of evil in Christianity by asserting that free will is the cause of all suffering. The first of its three volumes was completed in 388; the second and third were written between 391 and 395. The work is structured as a dialogue between Augustine and his companion Evodius; it ranges over several topics, and includes an attempted proof of the existence of God.
The philosophy of happiness is the philosophical concern with the existence, nature, and attainment of happiness. Some philosophers believe happiness can be understood as the moral goal of life or as an aspect of chance; indeed, in most European languages the term happiness is synonymous with luck. Thus, philosophers usually explicate on happiness as either a state of mind, or a life that goes well for the person leading it. Given the pragmatic concern for the attainment of happiness, research in psychology has guided many modern-day philosophers in developing their theories.
Religion is a distinct moral virtue whose purpose is to render God the worship due to Him as the source of all being and the giver of all good things. As such, in Christianity it is part of the cardinal virtue of Justice, and falls under obedience to the First Commandment.
Man-made law is law that is made by humans, usually considered in opposition to concepts like natural law or divine law.
Treatise on Law is Thomas Aquinas' major work of legal philosophy. It forms questions 90–108 of the Prima Secundæ of the Summa Theologiæ, Aquinas' masterwork of Scholastic philosophical theology. Along with Aristotelianism, it forms the basis for the legal theory of Catholic canon law.
In just war theory, a supreme emergency is a situation where a state faces an existential threat from an agressor, which scholars like Michael Walzer and John Rawls argue justifies otherwise unjust action.
The Ethics of Political Commemoration is a framework that seeks to improve remembrance of the past, so that it contributes to a better future. As a moral framework, it is adapted from the Just War tradition, reflecting that remembrance is often conducted with political – and sometimes coercive – intent.
