On one definition, a religion is an apparently universal social phenomenon involving some or all of the following:
Some religions are implicit, and consist of inherited ancestral traditions (a "way of life"). Others are organized, and promote themselves in conscious contrast to alternatives within the wider society. We may also distinguish between personal religious beliefs and experiences, and those which may be socially prescribed.
In the case of religions which are divided into sects or denominations, the word "religion" is generally reserved by adherents for the most fundamental level of spiritual identity. For example, Methodists generally do not describe Methodism as a "religion" in its own right, but as a denomination within the religion of Christianity. Sikhs, however, insist that they are a "religion," and not, for example, merely a sect of Hinduism (despite their many similarities).
There is a wide variety of religions, listed on Citizendium in our catalog of religions. It is estimated that there are about 10000 religions.[2] This article concerns the topic of religion in general.
The word religion comes from the Latin 're-ligare' [literally to 'tie again', 're-tie', 'bind'] which originally designated "a power outside man obligating him to certain behaviour under pain of threatened awesome retribution, a kind of tabu, or the feeling in man vis-a-vis such powers."[3] Equivalent terms in other cultures derive from very different ideas. In Sanskrit, dharma (often nowadays used to translate "religion") refers to duties, including etiquette, morality, ritual, caste obligations, and law; in Buddhism it evolved to refer to the Buddha's teachings.[4] The Arabic din was similar, referring to "usages, customs, standard behavior," even "conformity, propriety, obedience."[5] Classical Chinese and ancient Greek wholly lacked a word meaning "religion." The modern use the word to refer to a system of beliefs and practices (as in "the Christian religion") is only a few centuries old in European languages, prompting the renowned scholar of religion, Wilfred Cantwell Smith, to question the precision and usefulness of the noun (though not of the adjective "religious").
Even though religious phenomena have been contemplated and studied for millennia, modern scholars of religion do not agree on a single definition of the term. Before the nineteenth century, most people tended to define religion in terms of "true religion," meaning the understandings and actions of own religious tradition. With the spread of a scientific approach to history and social phenomena in the nineteenth century, religion began to be approached secularly and skeptically. The result was a series of hostile understandings of religion. The ideas of Karl Marx and later, Sigmund Freud, are illustrative:
Marx and Freud's "definitions" of religion reduced it to negative manifestation of another phenomenon, socioeconomic and psychological respectively. But subsequently, religion scholars began to view religion more neutrally. The sociologist Milton Yinger offered a "functional" definition: "religion can be defined as a system of beliefs and practices by means of which a group of people struggles with the ultimate problems of human life."[7] Besides the problem whether an individual can be religious apart from "a group of people," Yinger’s definition is so broad that it could include Marxism, patriotism, or even science. Emile Durkheim, one of the founders of the sociology of religion, offered a more specific definition: "a unified system of beliefs and practices relative to sacred things."[8] James Livingston, a phenomenologist of religion, offers the following "working definition": "religion is that system of activities and beliefs directed toward that which is perceived to be of sacred value and transforming power."[9]
One of the difficulties in defining religion is defining the "thing" to which humans are relating: God, the transcendent, the Ultimate, the Sacred, Ultimate Reality, the Holy. The terms reflect the multitude of ways humans experience ultimacy. For members of monotheistic traditions, the "thing" is a transcendent, personal God, creator of the cosmos. But for some Hindus "it" is one god among many, a high god among many, or even a sacred power pervading everything (humans, nature, and the gods). For Buddhists the ultimate experience is of nirvana, sometimes described as an ultimate state, but even then any description of nirvana is "empty." In the Chinese religious traditions, "it" is often called the dao, the way or order of all things.
Because religion has many elements or dimensions to it, there are many ways to study it. A scientific analogy might be oceanography; one must know biology to study sea life, chemistry to study sea water, physics to study the water's movements, and geology to study the marine bottom. Similarly, religion is made up of different elements:
The question of the origin of religion has produced a range of explanations, many of which get back to the definition of religion and its uses, both to help people and to deceive them. The earliest evidence of religious beliefs and practices are intentional burials of human beings, sometimes with grave goods, which may imply the existence of beliefs about an afterlife. Cave art, some of which portrays beings that are part human and part animal, may imply belief in spiritual or divine beings or in the transformation of human beings into something else. Elaborate arrangements of the skulls and bones of bears in caverns may imply the existence of rituals. In all these cases, material objects or images have been preserved; their uses and any beliefs and practices they might imply are inferences. To date, all evidence is confined to the last hundred thousand years and usually to the last fifty or even thirty thousand years.
The question of whether religion predates language has been debated. Essentially, the issue boils down whether ritual predates myth, whether people acted out religious feelings before they talked about them. Not enough is yet known about the origin of either language or religion to resolve the matter. Nicholas Wade, in Before the Dawn, notes that with the rise of language, deception became a social problem, hence religion in the form of a set of common beliefs, stories, and rituals was needed to create group solidarity and enforce group behavioral norms and expectations (including honesty and penalties for deception).[10]
Central to the purpose of religion has always been the need of human beings to find coherence and meaning in the world around them, whether through stories explaining the world's origin and mysteries (such as suffering and death) or rituals and practices that bring order and comfort. Because the need for meaning and coherence is seen as foundational to human existence, humans have been termed homo religiosus, the religious human being, by many scholars. Because of its power to explain and legitimize, religion has been central to the construction of societies, and has been used both to justify and subvert institutions. In the last few centuries, the rise of science and competition among an enormous plurality of religious traditions has diminished the role of religion somewhat, but it remains a powerful force for both good and evil.
What makes a religion important, or worth studying? Common criteria include
Religions are often grouped together because they share certain common features or heritages. The following terms are examples:
"Dharmic religions": Includes the several Indic religions which conceive of their teachings in terms of dharma (a word variously meaning "religion" or "duty"): Hinduism, Buddhism, Jainism, and Sikhism.
"Abrahamic religions": This category includes the three religions which recognize Abraham as a part of their sacred histories: Judaism, Christianity, and Islam. The Baha'i religion also fits this description, but is more frequently overlooked on account of its small size and recent appearance.
"Monotheistic religions": Religious which affirm belief in one God include Zoroastrianism, Sikhism, and the Abrahamic religions (listed above). Some strains of Hindu or ancient Egyptian religion arguably qualify. The concept becomes somewhat murky in view of the many theologies in which God or his equivalent boasts a heavenly retinue, or changes form. The concept of "henotheism" (in which any one of various deities may be singled out for worship as the Supreme Being) has been proposed to describe Hinduism.
"Eastern religions": Any of the traditional, indigenous religions of India, Tibet, or East Asia--especially Hinduism, Buddhism, Taoism, and Confucianism. Older material often includes Islam in this category; today it is more likely to be grouped with the "Western" (now usually conceived as identical with Abrahamic) religions.
Taoic religions: A family of East Asian religions which make use of the name / concept of Tao (or Dao): Taoism, Confucianism, Shinto, Yiguandao, Chondogyo, Caodaism, and others. Chinese Buddhism arguably qualifies.
Pagan / Heathen religions: These represent a Christian religious category encompassing all non-Christians except Jews, and perhaps also Muslims. "Pagan" comes from the Latin paganus ("country bumpkin"); "heathen" ("heath-dweller") has much the same set of connotations. The terms recall a time when Christianity was making inroads in European cities, while rustics often continued to follow the old religions. For centuries the terms were assumed to be negative; however, "neo-pagan" groups began reclaiming them in the twentieth century.
"People of the Book" (Ahl al-Kitab): An Islamic term for other monotheistic religions founded by prophets who revealed holy books. The Qur'an recognizes Judaism, Christianity, and "Sabeanism." (Scholars are unsure as to what a Sabean was.) Muslim theologians debated the status of Zoroastrianism and Hinduism.
"Tribal religions / Indigenous religions / Primitive religions / Primal religions": Include a wide variety of small-scale religions found in pre-modern societies. These terms are problematic: "tribe" is not a term recognized in anthropology (its origin lies in Roman history); "indigenous" begs many questions; while "primitive" may be perceived as insulting. "Shamanism" describes one common religious-specialist role within many such societies (but neither exhausts the category, nor is limited to it). Animism (after Tylor) names a type of belief system which is common within such societies.
"New Religious Movements" (NRM's): An umbrella term which encompasses groups which arose (at the very earliest) in the nineteenth century or later. Some scholars prefer World War II as a cutoff date. Scientology is an example; it recognizes the existence of a supreme being but has no doctrine about a practitioner's relationship with same, leaving that up to the individual. Not all NRM's claim to be religions per se; some say they are "spiritual movements," while others see themselves as part of another religion such as Christianity.
"Universal religions / Universalizing religions":[11] Those that address themselves to all humanity and have had a sufficient measure of success in doing so. This includes Buddhism, Christianity and Islam. Depending on definitions, it may also include smaller groups such as Baha'is.
"Ethnic religions": Those that are essentially the religion of a particular ethnic group, though they may include small numbers of others. This includes Hinduism, Judaism, Chinese religion and tribal religions.
"Segmental religions": These are religions that essentially form only part of a particular ethnic group, including Sikhism, Jainism, Cao Dai etc.
"Atheism": Not strictly a religion, "atheism" refers to the denial of any religious belief, or occasionally the absence of belief in any deity or deities; often associated with the position that religious belief is no different from any other superstitious or mythological belief.
Many sources give statistics for membership of religions, raising questions about what this actually means. The easiest and commonest (though not always consistently) practice is simply to ask people what their religion is (with parents answering for children). This gives the following rough world percentages.[12]
Questions are raised about this by theologians, sociologists and others. The figure for Christians includes many Westerners who call themsleves Christians when asked (or more usually identify with some particular branch) but do not practise, or sometimes even believe. Contrariwise, hundreds of millions of Chinese practise traditional rituals but say they have no religion. Scholars often make an exception to the self-identification method to count them as belonging to a Chinese ethnic religion (to which they give various names). Attempts to classify people by belief and/or practice are fraught with difficulty as it is rare for people even to have coherent belief systems, let alone practise them ([2]).
Religions without living adherents, especially those from long ago, are often described as myths. Descriptions of myths, however, tend to concentrate on tales associated with particular deities, and not on the form of the cult.
Dead religions are occasionally revived, often because they resonate with a particular cause.
