An epistle, commonly known as a letter, is a written communication directed to a specific person or group. Historically, epistles were often used in religious contexts, such as the letters written by the Apostle Paul in the New Testament of the Bible. These letters addressed various issues, provided guidance, and shared teachings with early Christian communities. In modern times, epistles can take various forms, including personal letters, formal correspondence, and even open letters published in media. They serve to convey thoughts, emotions, or information and can be handwritten or typed. The structure of an epistle typically includes a greeting, body, and closing.
