Throughout history, various groups of people have considered themselves to be the chosen people of a deity, for a particular purpose. The phenomenon of a "chosen people" is well known among the Israelites and Jews, where the term (עם סגולה / העם הנבחר) originally referred to the Israelites as being selected by Yahweh to worship only him and to fulfill the mission of proclaiming his truth throughout the world. Some claims of chosenness are based on parallel claims of Israelite ancestry, as is the case for the Christian Identity and Black Hebrew sects—both which claim themselves (and not Jews) to be the "true Israel". Others claim that the concept is spiritual, where individuals who genuinely believe in God are considered to be the "true" chosen people. This view is common among most Christian denominations, who historically believed that the church replaced Israel as the people of God.
Anthropologists commonly regard claims of chosenness as a form of ethnocentrism.
Jews as the chosen people
In Judaism, "chosenness" is the belief that the Jews, via descent from the ancient Israelites, are the chosen people, i.e., chosen to be in a covenant with God. The idea of the Israelites being chosen by God is found most directly in the Book of Deuteronomy, where it is applied to Israel at Mount Sinai upon the condition of their acceptance of the Mosaic covenant between themselves and the LORD God. The decalogue immediately follows, and the seventh day sabbath is given as the sign of the covenant, with a requirement that Israel keep it, or else be cut off. The verb 'bahar (), and is alluded to elsewhere in the Hebrew Bible using other terms such as "holy people". Much is written about these topics in rabbinic literature. The three largest Jewish denominations—Orthodox Judaism, Conservative Judaism and Reform Judaism—maintain the belief that the Jews have been chosen by God for a purpose. Sometimes this choice is seen as charging the Jewish people with a specific mission—to be a light unto the nations, and to exemplify the covenant with God as described in the Torah.
