Pseudo-Jerome — as excerpted in the Catena Aurea on Mark 1:1

“The Greek word ‘Evangelium’ means good tidings, in Latin it is explained, ‘bona annunciatio,’ or, the good news; these terms properly belong to the kingdom of God and to the remission of sins; for the Gospel is that, by which comes the redemption of the faithful and the beatitude of the saints. But the four Gospels are one, and one Gospel is four. In Hebrew, His name is Jesus, in Greek, Soter, in Latin, Salvator; but men say Christus in Greek, Messias in Hebrew, Unctus in Latin, that is, King and Priest.”
