Doctrine

philosophy religion Maturity 5-7 Next article →

The term doctrine comes from the Greek word for teaching or instruction. It refers to a codification of beliefs or a body of teachings. These teachings can serve as the essence of a specific branch of knowledge. They can also act as the core principles of a belief system. Essentially, doctrine organizes complex ideas into a structured set of positions. This structure provides a guide for how people understand their world.

In religious contexts, doctrine often describes principles shared by a church. Different traditions have unique ways of establishing these teachings. For example, Roman Catholic and Orthodox doctrines often stem from the writings of the Church Fathers. These ideas are sometimes clarified through various Ecumenical councils. In contrast, many Protestants reject these traditions. They derive their doctrine solely from the Bible. Some groups use a catechism, which is a longer written version of these teachings. Other groups use brief statements or prayer books for shorter versions.

Many specific religious doctrines exist across the globe. In Christianity, examples include the Trinity or the doctrine of atonement. Roman Catholic theology also includes teachings on transubstantiation. Calvinism is known for the doctrine of "double" predestination. Other faiths have their own central teachings. Hinduism includes the concept of Yuga. Jainism features the postulation known as Syādvāda. Buddhism teaches the Four Noble Truths. These different systems show how doctrine organizes spiritual thought.

Sociologist Mervin Verbit studied how doctrine relates to religiosity. He suggested that doctrine is a key component of how religious people behave. Verbit divided doctrine into four distinct categories. These categories are content, frequency, intensity, and centrality. Frequency refers to how much the doctrine occupies a person's mind. Intensity and centrality describe how deeply the belief is held. These four dimensions can vary between different religions. They can also vary between individuals within the same tradition.

Doctrine is also a vital term in military science. It refers to established procedures for executing warfare operations. Tactical doctrine provides a default approach for specific types of attacks. It includes a standard set of maneuvers, weapons, and troop types. History shows many different military doctrines. These include hit-and-run tactics and trench warfare from World War I. The Soviet Union used a strategy called deep battle during World War II. During the Cold War, leaders used strategic doctrines to contain Soviet expansion.

One notable example is the Carter Doctrine announced in 1980. President Jimmy Carter declared this after the Soviet occupation of Afghanistan. He stated that Soviet aggression in the Persian Gulf would threaten United States interests. This doctrine led to new military installations and the Rapid Deployment Force. It reinforced earlier policies like the Truman and Eisenhower doctrines. Modern peacekeeping also uses doctrine. The 2008 United Nations "Capstone Doctrine" integrates civilian and military operations.

In the legal field, a doctrine is a body of interrelated rules. These rules are often built over a long time through common-law traditions. A legal doctrine is usually associated with a specific concept or principle. For instance, the doctrine of frustration of purpose is part of contract law. This doctrine includes various tests, such as the non-occurrence of a crucial event. Doctrines can eventually grow to become entire branches of law. An example is restitution, which began as a concept but is now a separate branch.

Political doctrine involves principles regarding the power to govern a society. It is a theoretical discourse about what a topic should be. Some people confuse political doctrine with political ideology. However, doctrine lacks the actional aspect found in ideology. It is based on a set of rationally elaborated values. These values might exist before a person forms a political identity. Finally, the word is linked to the title of Doctor. This title means one has the authority to establish doctrine in a field. A doctorate is the academic degree that confers this legal authority.
