Religious symbols in the context of Cross

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.

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.
