The transcendent career of Christ Jesus is recorded in the message of four biographers: Matthew and John, who were traditionally accepted as disciples of the Master; Mark and Luke, who were not.
Though scholars seem to agree that the Epistles of Paul antedated the Gospels by at least a decade, the New Testament as printed in our Bibles very logically commences with these writings which we know as the four Gospels.
The word "Gospel," familiar to Bible readers, comes from two Saxon words (gōd and spel) meaning "good tidings." These records of the Master's life, then, are named "Gospels," as they contain the glorious "good tidings" mentioned by the evangelist Luke (2:10).
