Natural Law: A Guide For Catholics

how do catholics use natural law

Natural law is a concept that has been used by Catholic theologians and philosophers to guide moral teachings and actions. It is the idea that humans have an innate sense of morality, or a law written on their hearts, that allows them to discern between good and evil, independent of religious doctrine. This concept has been used by Catholics to argue against practices deemed unnatural and therefore immoral, such as conception, same-sex relationships, and assisted reproductive technologies. Natural law, in the Catholic tradition, is believed to be a universal principle from which all moral obligations and duties are derived. While interpretations vary, Catholic thinkers generally fall into two camps: those who emphasise authority and tradition, and those who favour contemporary experience and inductive reasoning. Natural law provides a framework for Catholics to evaluate the morality of laws and guide their actions towards attaining true happiness and salvation.

Catholics use natural law to denounce 'unnatural' acts, such as conception and same-sex sexual relations

Natural law, in the context of Catholicism, refers to a range of moral theories that rely on rational discernment of the natural order as a means of telling good from evil. Catholic natural law thinkers tend to fall into two broad camps: the first draws more from authority and deductive reasoning, while the second leans on contemporary experience and inductive reasoning.

Catholics use natural law to denounce "unnatural" and therefore immoral acts, such as conception, same-sex sexual relations, and many assisted reproductive technologies. They argue that the natural sex partner for a man is a woman, and vice versa, and that homosexuality is thus "unnatural". The Catechism of the Catholic Church names "homosexual acts" as "intrinsically immoral and contrary to natural law", and "homosexual tendencies" as "objectively disordered." Homosexual desires are not considered sinful in themselves, but acting upon them is considered a sin.

The Catholic Church teaches that sexual relations should be confined to lifelong marriage between one man and one woman, in which each marital act is open to both life and love. Contraception is considered evil as it renders procreation impossible and expresses a refusal to be open to life. The Church also forbids fornication, or sexual intercourse between two people not married to each other, as a "grave matter". Abortion is also considered homicide by the Church.

Some critics argue that the Church's interpretation of natural law is too narrow and overlooks the bigger picture of human nature. They argue that it confuses the nature of people with the function of their organs and does not take into account the circumstances and consequences of actions. Additionally, the Church's teachings on sexuality are often presented as absolute truths rather than as part of an ongoing search for understanding.

Natural law is used to understand civil society and the role of legitimate authority

Natural law is a concept that has been used by Catholic theologians to understand civil society and the role of legitimate authority. At its most basic level, natural law says to "do good and avoid evil". This is important for understanding civil society because it provides a framework for evaluating the morality of laws and the actions of governing authorities.

The Catechism of the Catholic Church describes natural law as "the original moral sense which enables man to discern by reason the good and the evil, the truth and the lie". This law is said to be "written and engraved in the soul of each and every man" and is understood as the rational creature's participation in the eternal law. According to St. Thomas Aquinas, the natural law is "nothing else than the rational creature's participation in the eternal law". Aquinas further taught that all human or positive laws should be judged by their conformity to the natural law.

In the context of civil society, natural law can be used to evaluate the legitimacy of authority and the morality of laws. For example, in the United States, the Supreme Court's decision to side with Hobby Lobby in refusing to provide abortifacient contraception in its company health plan was based on religious objections and a natural law interpretation. Similarly, during the civil rights movement, Dr. Martin Luther King, Jr. disobeyed Jim Crow laws while calling for the enforcement of the Supreme Court's decision in Brown v. Board of Education, citing a theory of natural law rooted in Catholic theology.

Catholic natural law thinkers tend to fall into two broad camps. The first approach draws more from authority and deductive reasoning, appealing to God's will as rationally discerned. The second approach leans on contemporary experience and inductive reasoning, arguing for revisions to official Catholic teaching in light of contemporary knowledge.

Natural law is also important for interpersonal apologetics. By appealing to natural law, evangelists can draw out their non-believing friends' inherent understanding of good and evil, as written on their hearts, rather than simply imparting knowledge to them. This approach can be more effective in persuading others to adopt a particular moral perspective.

It is a tool for interpersonal apologetics, persuading non-believers to Catholicism

Natural law is a tool for interpersonal apologetics, persuading non-believers to Catholicism. It is a set of moral theories that rely on rational discernment of the natural order to distinguish good from evil. The Catholic Church teaches that the natural law is written on the hearts of all men, not just Catholics, and that it is a tool to help people live reasonably within nature's designs.

The natural law is accessible to everyone with the actual use of reason. It is found in the legal codes, philosophical works, religious books, and literary monuments of all civilizations, both ancient and modern. This universality is important because it allows Catholics to engage in dialogue with non-believers and demonstrate that their moral intuitions align with Catholic teachings. For example, a non-believing friend may be persuaded that murder is wrong and that it involves the killing of an innocent human being. If they also believe that human life begins at conception, they may be more open to the Catholic perspective on abortion.

Natural law can also be used to defend Catholic teachings on matters such as contraception, same-sex sexual relations, and assisted reproductive technologies. By presenting clear and persuasive arguments, Catholics can engage in reasonable discourse with non-believers and address their criticisms and objections. This approach respects the fundamental nature of human persons and allows for dialogue and criticism, learning from new evidence and experience.

However, some critics argue that the Catholic Church's approach to natural law is confusing and unpersuasive, particularly on issues related to sexuality, gender, and reproduction. Some Catholics themselves are not convinced by the Church's natural law arguments in these areas, finding them unreasonable and inconsistent with contemporary knowledge. To address this, some Catholic scholars have argued for revisions to official Catholic teachings to better align with contemporary experience and inductive reasoning.

Natural law provides a secular framework to evaluate the morality of legislation and court rulings

Natural law is a moral theory that relies on rational discernment of the natural order as a means of telling good from evil. It is a concept that was initially developed by Greek Stoic philosophers, who believed that living reasonably within nature's designs produced a universally accessible moral theory. Christians, and specifically Catholics, appropriated natural law reasoning through the premise that observations of creation ought to reveal aspects of God the Creator's will.

The Catechism of the Catholic Church describes natural law as:

> "The natural law expresses the original moral sense which enables man to discern by reason the good and the evil, the truth and the lie: 'The natural law is written and engraved in the soul of each and every man, because it is human reason ordaining him to do good and forbidding him to sin...."

Catholic natural law thinkers tend to fall into two broad camps with significant diversity in each. The first approach draws more from authority and deductive reasoning and is characteristic of Vatican documents that tend to conserve traditional teachings through appeals to God's will as rationally discerned. The second approach leans on contemporary experience and inductive reasoning and has been utilized by a number of Catholic scholars to argue for revisions to official Catholic teaching in light of contemporary knowledge.

Natural law provides a secular framework for evaluating the morality of legislation and court rulings, or what is known as "positive law". This framework was notably used by Dr. Martin Luther King Jr. during the civil rights movement, when he disobeyed Jim Crow laws while simultaneously calling for the enforcement of the Supreme Court's decision in Brown v. Board of Education. King explained that there was a moral responsibility to obey just laws, and conversely, a moral responsibility to disobey unjust laws. He defined a just law as "a man-made code that squares with the moral law or the law of God," while an unjust law was "out of harmony with the moral law."

Natural law, therefore, provides a basis for evaluating the morality of legislation and court rulings, independent of religious doctrine, by appealing to universal principles of reason and nature.

It is used to defend the prohibition of certain behaviours, such as theft and drunkenness

Natural law, as understood by Catholics, is a system of moral principles derived from the nature of humans and the world. It is believed that God created humans with a rational nature that allows them to discern moral truths and apply them to their lives. These truths are considered universal and timeless, reflecting the order and purpose that God established in creation.

One of the key applications of natural law in Catholic teaching is to defend the prohibition of certain behaviours that are considered immoral and harmful.

Catholics use natural law to denounce what they consider "unnatural" and therefore immoral acts, such as conception, same-sex sexual relations, and certain assisted reproductive technologies. They also apply it to societal issues, such as civil rights and the moral responsibility to obey just laws while disobeying unjust ones.

Natural law provides a framework for evaluating the morality of positive law (legislation and court rulings). It helps determine if a law passed by a legitimate authority is immoral and whether it has binding authority.
