Religion

A religion is an apparently-universal human social phenomenon involving some or all of the following:

• a distinctive worldview
• doctrines, beliefs, or traditions
• the supernatural
• subjects of "ultimate concern" (such as birth and death)
• the concept of "the sacred"
• group identity
• social institutions
• practices, rituals, rules, other behavioral expectations
• the claim to be a religion

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 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 at catalog of religions. This article concerns the topic of religion in general.

Major religions of the world

What makes a religion important, or worth studying? Common criteria include

• Size, i.e. number of followers. Major problems include definitional ones (e.g., are we to count "Catholics" according to the number of people baptized as Catholics, the number who say they are Catholics, or the number who attend mass at least occasionally?) as well as practical problems of enumeration. Adherents.com is a well-known site which compiles population estimates for various religions.

• Antiquity, i.e. the age of a religion (with older ones generally being regarded as more venerable). This is not always easily calculated. For example, to many it seems obvious that Judaism is older than Christianity, which in turn is older than Islam; yet all three emerged from (and lay claim to) much the same prophetic tradition. Moreover, the basic features of (rabbinic) Judaism and Christianity as we know them coalesced at about the same time, during the second-to-fourth centuries AD. And should the International Society for Krishna Consciousness be traced back to the 1960's activity of A.C. Bhaktivedanta Prabhupada; to the career of the fifteenth-century Bengali saint Caitanya; to the composition of the Bhagavadgita some two thousand years ago; or to Krishna himself (if he in fact existed as a historical figure)?

• Influence. While this is difficult to quantify with anything like objectivity, several religions have clearly influenced the world beyond what their numbers would suggest. For example, many of the characteristic features of the Abrahamic religions seem to have originated with Zoroastrianism, whose presence is now much reduced. And Jews have never been very numerous, but an intellectual history of the world could hardly be written without reference to them.

• Intrinsic interest. Often interest in a religion is inspired by some noteworthy event or attribute, whether good or bad.

Classification of Religions

The following categories are often encountered:

"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 categeory, 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 "spirtual movements," while others see themselves as part of another religion such as Christianity.
