A gospel is an account describing the life, death, and resurrection of Jesus of Nazareth. The most widely known examples are the four canonical gospels of Matthew, Mark, Luke, and John which are included in the New Testament, but the term can also be used to refer to apocryphal, non-canonical, Jewish–Christian and gnostic gospels.
Christianity places a high value on the four canonical gospels, which it considers to be revelations from God and central to its belief system. Christianity traditionally teaches that the four canonical gospels are an accurate and authoritative representation of the life of Jesus, but many scholars and historians, as well as some Christians, believe that much of that which is contained in the gospels is not historically reliable.
The baptism of Jesus and the crucifixion of Jesus are events almost universally agreed upon by biblical scholars to be historically authentic. Elements whose historical authenticity is disputed include the two accounts of the nativity of Jesus, as well as certain details about the crucifixion and the resurrection.
The word gospel derives from the Old English gōd-spell (rarely godspel), meaning "good news" or "glad tidings", and is a calque (word-for-word translation) of the Greek word εὐαγγέλιον, euangelion (eu- "good", -angelion "message") or in Aramaic (ܐܘܢܓܠܝܘܢ ewang'eliyawn). The gospel was considered the "good news" of the coming Kingdom of Messiah, and of redemption through the life and death and resurrection of Jesus, the central Christian message. The Greek word euangelion is also the source (via Latinised evangelium) of the terms "evangelist" and "evangelism" in English. The authors of the four canonical Christian gospels are known as the Four Evangelists.
