Major religious groups

The world's principal religions and spiritual traditions may be classified into a small number of major groups, though this is not a uniform practice. This theory began in the 18th century with the goal of recognizing the relative degrees of civility in different societies,<ref>Template:Cite book</ref> but this concept of a ranking order has since fallen into disrepute in many contemporary cultures.

Religious demographics

One way to define a major religion is by the number of current adherents. The population numbers by religion are computed by a combination of census reports and population surveys, in countries where religion data is not collected in census, for example the United States or France. Results can vary widely depending on the way questions are phrased, the definitions of religion used and the bias of the agencies or organizations conducting the survey. Informal or unorganized religions are especially difficult to count.

There is no consensus among researchers as to the best methodology for determining the religiosity profile of the world's population. A number of fundamental aspects are unresolved:

• Whether to count "historically predominant religious culture[s]".<ref>Template:Cite book</ref>
• Whether to count only those who actively "practice" a particular religion.<ref>Template:Cite web</ref>
• Whether to count based on a concept of "self-identification as adherents".<ref>Template:Cite web</ref>
• Whether to count only those who expressly self-identify with a particular denomination.<ref>Template:Cite web</ref>
• Whether to count only adults, or to include children as well.
• Whether to rely on official government-provided statistics.<ref>Template:Cite web</ref>Template:Not in citation given
• Whether to use multiple sources and ranges or single "best source(s)".

However, the Baháʼí Faith considers itself an independent religious tradition, which draws from Islam but also other traditions. The Baháʼí Faith may also be classed as a new religious movement, due to its comparatively recent origin, or may be considered sufficiently old and established for such classification to not be applicable.</ref>

Classification

Template:Further Template:More citations needed section Religious traditions fall into super-groups in comparative religion, arranged by historical origin and mutual influence. Abrahamic religions originate in the Middle East,<ref>Template:Cite book</ref><ref>Template:Cite web</ref> Indian religions in the Indian subcontinent (South Asia) and East Asian religions in East Asia.<ref>Template:Cite book</ref> Another group with supra-regional influence are Afro-American religion,<ref>Template:Cite book</ref> which have their origins in Central and West Africa.

• Middle Eastern religions:<ref name="Britannica">Template:Cite web</ref>
  • Abrahamic religions are the largest group, and these consist mainly of Judaism, Christianity, Islam, and the Baháʼí Faith. They are named for the Hebrew patriarch Abraham, and are unified by the practice of monotheism. Today, at least 3.8 billion people are followers of Abrahamic religions<ref>Template:Cite web</ref> and are spread widely around the world apart from the regions around East and Southeast Asia. Several Abrahamic organizations are vigorous proselytizers.<ref>Template:Cite book</ref> Abrahamic religions with fewer adherents include the Baháʼí Faith,<ref name="Abulafia-2019" /> the Druze faith,<ref name="Abulafia-2019" /> Samaritanism,<ref name="Abulafia-2019" /> and Rastafari.<ref name="Abulafia-2019">Template:Cite web</ref>
  • Iranian religions, partly of Indo-European origins,Template:SfnTemplate:Sfn include Zoroastrianism, Yazdânism, Uatsdin, Yarsanism, Manichaeism, and Yazidism.<ref>Template:Cite encyclopedia</ref>
  • Gnosticism, including historical traditions of Mandaeism, which is still alive in the Middle East and diaspora.<ref>Template:Cite web</ref>
• Eastern religions:
  • Indian religions, originated in Greater India and they tend to share a number of key concepts, such as dharma, karma, reincarnation among others. They are of the most influence across the Indian subcontinent, East Asia, Southeast Asia, as well as isolated parts of Russia. The main Indian religions are Hinduism, Jainism, Buddhism and Sikhism.
  • East Asian religions consist of several East Asian religions which make use of the concept of Tao (in Chinese), Đạo (in Vietnamese) or Dō (in Japanese or Korean). They include many Chinese folk religions, Taoism and Confucianism, as well as Vietnamese, Korean and Japanese religions, which are influenced by Chinese religious thought.
• Indigenous ethnic religions, found on every continent, now marginalized by the major organized faiths in many parts of the world or persisting as undercurrents (folk religions) of major religions. Includes traditional African religions, Asian shamanism, Native American religions, Austronesian and Australian Aboriginal traditions, Chinese folk religions, and postwar Shinto. Under more traditional listings, this has been referred to as "paganism" along with historical polytheism.
  • African religions:<ref name="Britannica" />
    • The religions of the tribal peoples of Sub-Saharan Africa, but excluding ancient Egyptian religion, which is considered to belong to the ancient Middle East;<ref name="Britannica" />
    • African diasporic religions practiced in the Americas, imported as a result of the Atlantic slave trade of the 16th to 18th centuries, building on traditional religions of Central and West Africa.
• New religious movement is the term applied to any religious faith which has emerged since the 19th century, often syncretizing, re-interpreting or reviving aspects of older traditions such as Ayyavazhi, Mormonism, Ahmadiyya, Jehovah's Witnesses, polytheistic reconstructionism, and so forth.

Christian categorizations

Initially, Christians had a simple dichotomy of world beliefs: Christian civility versus foreign heresy or barbarity. In the 18th century, "heresy" was clarified to mean Judaism and Islam;<ref>Template:Cite book</ref> along with paganism, this created a fourfold classification which spawned such works as John Toland's Nazarenus, or Jewish, Gentile, and Mahometan Christianity,<ref>Template:Cite book</ref> which represented the three Abrahamic religions as different "nations" or sects within religion itself, the "true monotheism."

Daniel Defoe described the original definition as follows: "Religion is properly the Worship given to God, but 'tis also applied to the Worship of Idols and false Deities."<ref>Template:Cite book</ref> At the turn of the 19th century, in between 1780 and 1810, the language dramatically changed: instead of "religion" being synonymous with spirituality, authors began using the plural, "religions", to refer to both Christianity and other forms of worship. Therefore, Hannah Adams's early encyclopedia, for example, had its name changed from An Alphabetical Compendium of the Various Sects... to A Dictionary of All Religions and Religious Denominations.Template:Sfn<ref>Template:Cite book</ref>

In 1838, the four-way division of Christianity, Judaism, Mahommedanism (archaic terminology for Islam) and paganism was multiplied considerably by Josiah Conder's Analytical and Comparative View of All Religions Now Extant among Mankind. Conder's work still adhered to the four-way classification, but in his eye for detail he puts together much historical work to create something resembling the modern Western image: he includes Druze, Yazidis, Mandaeans, and ElamitesTemplate:Clarify<ref>Template:Cite book</ref> under a list of possibly monotheistic groups, and under the final category, of "polytheism and pantheism", he listed Zoroastrianism, "Vedas, Puranas, Tantras, Reformed sects" of India as well as "Brahminical idolatry", Buddhism, Jainism, Sikhism, Lamaism, "religion of China and Japan", and "illiterate superstitions" as others.Template:Sfn<ref>Template:Cite book</ref>

The modern meaning of the phrase "world religion", putting non-Christians at the same level as Christians, began with the 1893 Parliament of the World's Religions in Chicago. The Parliament spurred the creation of a dozen privately funded lectures with the intent of informing people of the diversity of religious experience: these lectures funded researchers such as William James, D. T. Suzuki, and Alan Watts, who greatly influenced the public conception of world religions.Template:Sfn

In the latter half of the 20th century, the category of "world religion" fell into serious question, especially for drawing parallels between vastly different cultures, and thereby creating an arbitrary separation between the religious and the secular.<ref>Template:Cite journal</ref>

Islam categorizations

In Islam, the Quran mentions three categories: Muslims, the People of the Book, and idol worshipers.
