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 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 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.
