The gospel

The gospel or good news is a theological concept in several religions. In the historical Roman imperial cult and today in Christianity, the gospel is a message about salvation by a divine figure, a savior, who has brought peace or other benefits to humankind. In Ancient Greek religion, the word designated a type of sacrifice or ritual dedication intended to thank the gods upon receiving good news.

The religious concept is found at least as far back as Greece's Classical era and Roman authors are known to have adopted it toward the end of the 1st century BCE. It is a central message of Christianity today, in which written accounts of the life and teaching of Jesus Christ are known as Gospels. Provided by Wikipedia
