- Judaism (Hebrew: יַהֲדוּת Yahăḏūṯ) is the oldest Abrahamic religion. Judaism is monotheistic, and widely an ethnic religion. It comprises the collective spiritual, cultural, and legal traditions of the Jewish people, having originated as an organized religion in the Middle East during the Bronze Age. Contemporary Judaism evolved from Yahwism, the cultic religious movement of ancient Israel and Judah, around the 6th/5th century BCE, and is thus considered to be one of the oldest monotheistic religions. Religious Jews regard Judaism as their means of observing the Mosaic covenant, which was established between God and the Israelites, their ancestors. Jewish religious doctrine encompasses a wide body of texts, practices, theological positions, and forms of organization.
