The Greek word commonly translated as “gospel” or “good news” in the New Testament is euangelion.
Euangelion comes from Greek roots associated with good news or a good message. In early Christian writing, it came to refer especially to the good news about Jesus Christ, including his ministry, death, and resurrection. English words such as “evangelism” and “evangelist” ultimately derive from the same word family.
The term can describe the Christian message generally or the written accounts known as the four Gospels. The New Testament also uses related language for proclaiming the message. Euangelion should not be confused with parousia, which refers to an arrival or presence, or kerygma, a related term for proclamation or preaching.
