The modern English word "Gospel" is derived from the Anglo-Saxon word _Godspell_, which means "God story," the story about the life of God in human flesh. It does not, therefore, exactly correspond with the Greek name _euaggelion_, which means "good tidings." In the earliest times the Greek name meant the good tidings proclaimed by our Lord about the Kingdom of God which He had come to establish. And, as our Lord Himself rules over this kingdom, the tidings about the kingdom included tidings about Himself. So Christ Himself says, "for My sake and the gospel's" (Mark viii. 35). After the Ascension of our Lord and the disappearance of His visible presence, the _euaggelion_ came to mean the good tidings about Christ, rather than the good tidings brought by Christ (see 1 Cor. ix. 14 and 2 Cor. iv. 4). So St. Paul generally means by _euaggelion_ the good news, coming from God, of salvation freely given to man through Christ. When he speaks of "My gospel" (Rom. ii. 16), he means "my explanation of the gospel;" and when he says, "I had been intrusted with the gospel of the uncircumcision" (Gal. ii. 7), he means that he had been appointed by God to preach the good tidings to the Gentiles, with special emphasis on the points most necessary for their instruction. The word _euaggellon_, in the sense of a written gospel, is first found in the ancient Christian manual called the _Didaché_, or _Teaching of the Twelve Apostles_, in ch. xv.: "Reprove one {10} another, not in anger but in peace, as ye have it in the gospel." This book was probably composed about A.D. 100. The word seems to have been still more definitely applied to a written account of the life of Christ in the time of the great heretic Marcion, A.D. 140. The plural word _euaggelia_, signifying the Four Gospels, is first found in a writing of Justin Martyr,[1] about A.D. 152. It is important to notice that he also calls them "Memoirs of the Apostles," and that he refers to them collectively as "the Gospel," inasmuch as they were, in reference to their distinctive value as records of Christ, one book.
