Religious movements

 In the 19th and 20th centuries, the academic practice of comparative religion divided religious belief into philosophically defined categories called "world religions." However, some recent scholarship has argued that not all types of religion are necessarily separated by mutually exclusive philosophies, and furthermore that the utility of ascribing a practice to a certain philosophy, or even calling a given practice religious, rather than cultural, political, or social in nature, is limited. The current state of psychological study about the nature of religiousness suggests that it is better to refer to religion as a largely invariant phenomenon that should be distinguished from cultural norms (ie "religions"). The list of religious movements given here is therefore an attempt to summarize the most important regional and philosophical influences on local communities, but it is by no means a complete description of every religious community, nor does it explain the most important elements of individual religiousness.

The four largest religious groups by population, estimated to account for between 5 and 7 billion people, are Christianity, Islam, Buddhism, and Hinduism (with the relative numbers for Buddhism and Hinduism dependent on the extent of syncretism ).

• Christianity     2.1 billion – 2.2 billion     33% – 34%          Christianity by country
• Islam              1.5 billion – 1.6 billion      22% – 23%         Islam by country
• Buddhism      500 million – 1.9 billion     7% – 29%           Buddhism by country
• Hinduism       1.0 billion – 1.1 billion     15.2% – 16.2%     Hinduism by country

>>Abrahamic religions are monotheistic religions which believe they descend from Abraham .

• Judaism is the oldest Abrahamic religion, originating in the people of ancient Israel and Judea . Judaism is based primarily on the Torah , a text which some Jews believe was handed down to the people of Israel through the prophet Moses in 1,400 BCE. This along with the rest of the Hebrew Bible and the Talmud are the central texts of Judaism. The Jewish people were scattered after the destruction of the Temple in Jerusalem in 70 CE. Today there are about 13 million Jews, about 40 per cent living in Israel and 40 per cent in the United States.
• Christianity is based on the life and teachings of Jesus of Nazareth (1st century) as presented in the New Testament . The Christian faith is essentially faith in Jesus as the Christ , the Son of God , and as Savior and Lord. Almost all Christians believe in the Trinity , which teaches the unity of Father , Son (Jesus Christ), and Holy Spirit as three persons in one Godhead . Most Christians can describe their faith with the Nicene Creed . As the religion of Byzantine Empire in the first millennium and of Western Europe during the time of colonization, Christianity has been propagated throughout the world. The main divisions of Christianity are, according to the number of adherents:

               - Catholic Church , headed by the Pope in Rome , is a communion of the Western church and  22    Eastern Catholic churches .
               - Protestantism , separated from the Catholic Church in the 16th-century Reformation and split in many denominations,
               - Eastern Christianity which include Eastern Orthodoxy , Oriental Orthodoxy and the Church of the East .
               There are other smaller groups, such as Jehovah's Witnesses and the Latter Day Saint movement , whose inclusion in Christianity is sometimes disputed.

• Islam refers to the religion taught by the Islamic prophet Muhammad , a major political and religious figure of the 7th century CE. Islam is the dominant religion of northern Africa, the Middle East, and South Asia. As with Christianity, there is no single orthodoxy in Islam but a multitude of traditions which are generally categorized as Sunni and Shia , although there are other minor groups as well. Wahhabi is the dominant Muslim schools of thought in the Kingdom of Saudi Arabia . There are also several Islamic republics , including Iran , which is run by a Shia Supreme Leader .
• The Bahá'í Faith was founded in the 19th century in Iran and since then has spread worldwide. It teaches unity of all religious philosophies and accepts all of the prophets of Judaism, Christianity, and Islam as well as additional prophets including its founder Bahá'u'lláh .
• Smaller regional Abrahamic groups, including Samaritanism (primarily in Israel and the West Bank), the Rastafari movement (primarily in Jamaica), and Druze (primarily in Syria and Lebanon).

>>Indian religions are practiced or were founded in the Indian subcontinent . Concepts most of them share in common include dharma , karma , reincarnation , mantras , yantras , and darśana .

• Hinduism is a synecdoche describing the similar philosophies of Vaishnavism , Shaivism , and related groups practiced or founded in the Indian subcontinent . Concepts most of them share in common include karma , caste , reincarnation , mantras , yantras , and darśana . Hinduism is not a monolithic religion in the Romanic sense but a religious category containing dozens of separate philosophies amalgamated as Sanātana Dharma .
• Jainism , taught primarily by Parsva (9th century BCE) and Mahavira (6th century BCE), is an ancient Indian religion that prescribes a path of non-violence for all forms of living beings in this world. Jains are found mostly in India.
• Buddhism was founded by Siddhattha Gotama in the 6th century BCE. Buddhists generally agree that Gotama aimed to help sentient beings end their suffering (dukkha) by understanding the true nature of phenomena , thereby escaping the cycle of suffering and rebirth ( saṃsāra ), that is, achieving Nirvana .

               - Theravada Buddhism , which is practiced mainly in Sri Lanka and Southeast Asia alongside folk religion, shares some characteristics of Indian religions. It is based in a large collection of texts called the Pali Canon .
               - Under the heading of Mahayana (the "Great Vehicle") fall a multitude of doctrines which began their development in China and are still relevant in Vietnam , in Korea , in Japan , and to a lesser extent in Europe and the United States . Mahayana Buddhism includes such disparate teachings as Zen , Pure Land , and Soka Gakkai .
               - Vajrayana Buddhism , sometimes considered a form of Mahayana, was developed in Tibet and is still most prominent there and in surrounding regions.
               - Two notable new Buddhist sects are Hòa Hảo and the Dalit Buddhist movement , which were developed separately in the 20th century.

• Sikhism is a monotheistic religion founded on the teachings of Guru Nanak and ten successive Sikh Gurus in 15th century Punjab . Sikhs are found mostly in India.

>>Iranian religions are ancient religions which roots predate the Islamization of the Greater Iran . Nowadays these religions are practiced only by minorities.

• Zoroastrianism is a religion and philosophy based on the teachings of prophet Zoroaster in the 6th century BC. The Zoroastrians worship the Creator Ahura Mazda . In Zoroastrianism good and evil have distinct sources, with evil trying to destroy the creation of Mazda, and good trying to sustain it.
• Mandaeism is a monotheistic religion with a strongly dualistic worldview. Mandaeans are sometime labeled as the "Last Gnostics ".
• Kurdish religions include the traditional beliefs of the Yazidi , Alevi , and Ahl-e Haqq . Sometimes these are labeled Yazdânism .

>>Folk religion is a term applied loosely and vaguely to less-organized local practices. It is also called paganism , shamanism , animism , ancestor worship , matriarchal religion , or totemism , although not all of these elements are necessarily present in local belief systems. The category of "folk religion" can generally include anything that is not part of an organization. Modern neopagan movement draws on folk religion for inspiration to varying degrees.

• African traditional religion is a category including any type of religion practiced in Africa before the arrival of Islam and Christianity, such as Yoruba religion or San religion . There are many varieties of religions developed by Africans in the Americas derived from African beliefs, including Santería , Candomblé , Umbanda , Vodou , and Oyotunji .
• Folk religions of the Americas include Aztec religion , Inca religion , Maya religion , and modern Catholic beliefs such as the Virgin of Guadalupe . Native American religion is practiced across the continent of North America.
• Australian Aboriginal culture contains a mythology and sacred practices characteristic of folk religion.
• Chinese folk religion , practiced by Chinese people around the world, is a primarily social practice including popular elements of Confucianism and Taoism , with some remnants of Mahayana Buddhism. Most Chinese do not identify as religious due to the strong Maoist influence on the country in recent history, but adherence to religious ceremonies remains common. New religious movements include Falun Gong and I-Kuan Tao .
• Traditional Korean religion is a syncretic mixture of Mahayana Buddhism and Korean shamanism . Unlike Japanese Shinto, Korean shamanism was never codified and Buddhism was never made a social necessity. In some areas these traditions remain prevalent, but Korean-influenced Christianity is also influential in society and politics in South Korea.
• Traditional Japanese religion is a mixture of Mahayana Buddhism and ancient indigenous practices which were codified as Shinto in the 19th century. Japanese people retain nominal attachment to both Buddhism and Shinto through social ceremonies, but irreligion is common.

>>A variety of new religious movements still practiced today have been founded in many other countries besides Japan and the United States, including:

• Shinshūkyō is a general category for a wide variety of religious movements founded in Japan since the 19th century. These movements share almost nothing in common except the place of their founding. The largest religious movements centered in Japan include Soka Gakkai , Tenrikyo , and Seicho-No-Ie among hundreds of smaller groups.
• Cao Đài is a syncretistic, monotheistic religion, established in Vietnam in 1926.
  Unitarian Universalism is a religion characterized by support for a "free and responsible search for truth and meaning."
• Scientology teaches that people are immortal beings who have forgotten their true nature. Its method of spiritual rehabilitation is a type of counseling known as auditing , in which practitioners aim to consciously re-experience painful or traumatic events in their past in order to free themselves of their limiting effects.
• Eckankar is a religion with the purpose of making God an everyday reality in one's life.

Sociological classifications of religious movements suggest that within any given religious group, a community can resemble various types of structures, including "churches", "denominations", "sects", "cults", and "institutions".
