Monotheism refers to belief in one God in Comparative religion, though its meaning depends heavily on context and interpretation.

Etymology

Monotheism is from the Greek monos (single, alone) and theos (god)[1]. The English term was coined in the 17th century to name the belief in one God[2]. The concept is older than the term; ancient Hebrew, Christian, and Islamic theology developed extensive accounts of divine unity long before the English vocabulary existed.

A common misunderstanding

even among monotheistic traditions, ideas of divine unity, personhood, revelation, and worship can differ greatly.

In Practice

The Abrahamic traditions are the most prominent monotheistic traditions[2]. Judaism affirms the Shema (Hear, O Israel: the Lord our God, the Lord is one) as its central confession[3]. Christianity affirms one God in three persons (the Trinity), holding this Trinitarian formulation as monotheistic against accusations of polytheism from Jewish and Islamic perspectives. Islamic theology centers tawhid, the absolute oneness of God, and treats associating partners with God (shirk) as the gravest theological error. The Baha'i Faith and Sikhism are also strongly monotheistic.

Some Hindu traditions can be characterized as monotheistic in nuanced ways. Vaishnava traditions emphasize Vishnu (or Krishna) as the supreme personal God; Shaiva traditions emphasize Shiva similarly; certain philosophical schools (Vishishtadvaita, for instance) develop sophisticated monotheistic theologies. Other Hindu traditions are better described as inclusive monotheism (one ultimate reality manifest as many deities) or by other categories.

Zoroastrianism has been characterized as ethical dualism with a strongly monotheistic God (Ahura Mazda) opposed by an opposing principle (Angra Mainyu), making its classification debated.

Comparative study has shown that strict monotheism (only one being can be called God) is theologically demanding and historically less common than functional monotheism (one supreme being worshipped, with other lesser beings recognized)[4]. Many traditions move between these positions in complex ways.

Scholarly Context

Comparative monotheism has been an active scholarly area. Jan Assmann's writing on the Mosaic distinction and the history of monotheism[4], Robert Wright's The Evolution of God[5], and many others have explored how monotheism developed historically and what it implies theologically. The category is itself contested, with scholars debating whether it is a useful comparative term or imports specific Abrahamic assumptions.

Common Misconceptions

Misconception: Christianity is not really monotheistic because of the Trinity.

Correction: Trinitarian theology is monotheistic by Christian self-understanding: one God in three persons, not three gods. The doctrine has been defended as monotheistic against precisely this challenge for centuries[2].

Misconception: Monotheism is the most advanced form of religion.

Correction: Evolutionary framings of religious development that place monotheism at the top have been substantially abandoned in religious studies. The category is descriptive of certain traditions, not a ranking.
