World religions in the context of "Theosophy"

The perennial philosophy (Latin: philosophia perennis), also referred to as perennialism and perennial wisdom, is a school of thought in philosophy and spirituality that posits that the recurrence of common themes across world religions illuminates universal truths about the nature of reality, humanity, ethics, and consciousness. Some perennialists emphasize common themes in religious experiences and mystical traditions across time and cultures; others argue that religious traditions share a single metaphysical truth or origin from which all esoteric and exoteric knowledge and doctrine have developed.

Perennialism has its roots in the Renaissance-era interest in neo-Platonism and its idea of the One from which all existence emerges. Marsilio Ficino (1433–1499) sought to integrate Hermeticism with Greek and Christian thought, discerning a prisca theologia found in all ages. Giovanni Pico della Mirandola (1463–1494) suggested that truth could be found in many—rather than just Biblical and Aristotelian traditions. He proposed a harmony between the thought of Plato and Aristotle and saw aspects of the prisca theologia in Averroes (Ibn Rushd), the Quran, Kabbalah, and other sources. Agostino Steuco (1497–1548) coined the term philosophia perennis.

Religious studies, also known as religiology or the study of religion, is the study of religion from a historical or scientific perspective. There is no consensus on what qualifies as religion and its definition is highly contested. It describes, compares, interprets, and explains religion, emphasizing empirical, historically based, and cross-cultural perspectives.

While theology attempts to understand the transcendent or supernatural according to traditional religious accounts, religious studies takes a more scientific and objective approach, independent of any particular religious viewpoint. Religious studies thus draws upon multiple academic disciplines and methodologies including anthropology, sociology, psychology, philosophy, and history of religion.

Manichaeism (/ˌmænɪˈkiːɪzəm/; in Persian: آئین مانی, romanized: Āʾīn-i Mānī; Chinese: 摩尼教; pinyin: Móníjiào) was a major world religion founded in the third century CE by the Parthian Iranian prophet Mani (C.E. 216–274) in the Sasanian Empire. Variably described as a Christian heresy and a Gnostic movement, Manichaeism was an organized and doctrinal religious tradition in its own right. It taught an elaborate dualistic cosmology describing the struggle between a good spiritual world of light, and an evil material world of darkness. Through an ongoing process that takes place in human history, light is gradually removed from the world of matter and returned to the world of the divine.

Mani's teachings were intended to integrate, succeed, and surpass the "partial truths" of various prior faiths and belief systems, including Platonism, Christianity, Zoroastrianism, Buddhism, Marcionism, Hellenistic and Rabbinic Judaism, Gnostic movements, Ancient Greek religion, Babylonian and other Mesopotamian religions, and mystery cults. Some forms of Manichaeism see Mani as the final prophet after Zoroaster, the Buddha, and Jesus. The Manichaean scriptural canon includes seven works attributed to Mani, written originally in Syriac. Manichaean sacramental rites included prayers, almsgiving, and fasting. Communal life centered on confession and the singing of hymns.

Indigenous religion or native religion is a category used in the study of religion to demarcate the religious belief systems of communities described as being "indigenous". This category is often juxtaposed against others such as the "world religions" and "new religious movements". The term is commonly applied to a range of different belief systems across the Americas, Australasia, Asia, Africa, and Northern Europe, particularly to those practiced by communities living under the impact of colonialism.

The term "indigenous religions" is usually applied to the localised belief systems of small-scale societies. These belief systems do not typically engage in proselytization, thus distinguishing them from movements like Christianity, Islam, Hinduism, and Buddhism that all seek converts and which are typically classified as "world religions". They are also often characterised as being distinct from the "world religions" because they are orally transmitted, intertwined with traditional lifestyles, and pluralist. Numerically, most of the world's religions could be classed as "indigenous", although the number of "indigenous religionists" is significantly smaller than the number of individuals who practice one of the "world religions".

Comparative religion is the branch of the study of religions with the systematic comparison of the doctrines and practices, themes and impacts (including migration) of the world's religions. In general the comparative study of religion yields a deeper understanding of the fundamental philosophical concerns of religion such as ethics, metaphysics and the nature and forms of salvation. It also considers and compares the origins and similarities shared between the various religions of the world. Studying such material facilitates a broadened and more sophisticated understanding of human beliefs and practices regarding the sacred, numinous, spiritual and divine.

In the field of comparative religion, a common geographical classification of the main world religions distinguishes groups such as Middle Eastern religions (including Abrahamic religions and Iranian religions), Indian religions, East Asian religions, African religions, American religions, Oceanic religions, and classical Hellenistic religions.
