The Tractatus Theologico-Politicus (TTP) or Theologico-Political Treatise, is a 1670 work of philosophy written in Latin by the Dutch philosopher Benedictus Spinoza (1632–1677). The book was one of the most important and controversial texts of the early modern period. Its aim was "to liberate the individual from bondage to superstition and ecclesiastical authority." In it, Spinoza expounds his views on contemporary Jewish and Christian religion and critically analyses the Bible, especially the Old Testament, which underlies both. He argues what the best roles for state and religion should be and concludes that a degree of democracy and freedom of speech and religion works best, such as in Amsterdam, while the state remains paramount within reason. The goal of the state is to guarantee the freedom of citizens. Religious leaders should not interfere in politics. Spinoza interrupted his writing of his magnum opus, the Ethics, to respond to the increasing intolerance in the Dutch Republic, directly challenging religious authorities and their power over freedom of thought. He published the work anonymously, in Latin, rightly anticipating harsh criticism and vigorous attempts by religious leaders and conservative secular authorities to suppress his work entirely. He halted the publication of a Dutch translation. One described it as being "Forged in hell by the apostate Jew working together with the devil". The work has been characterized as "one of the most significant events in European intellectual history", laying the groundwork for ideas about liberalism, secularism, and democracy.

In Judaism, the concept of the Jews as chosen people is the belief that the Jews as a subset, via partial descent from the ancient Israelites, are also chosen people, i.e. selected to be in a covenant with God. Israelites being properly the chosen people of God is found directly in the Book of Deuteronomy 7:6 as the verb baḥar (בָּחַר), and is alluded to elsewhere in the Hebrew Bible using other terms such as "holy people" as goy or gentile, Book of Exodus 19:6. 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 by believers 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.
