"Gentiles" is a term used primarily in religious contexts to refer to people who are not part of the Jewish faith. In the Bible, Gentiles are often contrasted with the Israelites, who are considered God's chosen people. The term encompasses a wide range of cultures and ethnicities outside of Judaism. In the early days of Christianity, the inclusion of Gentiles became a significant topic, as many early followers were Jews. The Apostle Paul played a crucial role in spreading the message of Christianity to Gentiles, emphasizing that faith, rather than ethnic background, was the key to salvation.
