Gospel originally meant the Christian message, but in the 2nd century it came to be used also for the books in which the message was reported. In this sense a gospel can be defined as a loose-knit, episodic narrative of the words and deeds of Jesus, culminating in his trial and death and concluding with various reports of his post-resurrection appearances. Modern biblical scholars are cautious of relying on the gospels uncritically, but nevertheless, they provide a good idea of the public career of Jesus, and critical study can attempt to distinguish the original ideas of Jesus from those of the later Christian authors.

The Gospel of Mark is the second of the four canonical gospels and one of the three synoptic Gospels. It tells of the ministry of Jesus from his baptism by John the Baptist to his death, the burial of his body, and the discovery of his empty tomb. It portrays Jesus as a teacher, an exorcist, a healer, and a miracle worker, though it does not mention a miraculous birth or divine pre-existence. He refers to himself as the Son of Man. He is called the Son of God but keeps his messianic nature secret; even his disciples fail to understand him. All this is in keeping with the Christian interpretation of prophecy, which is believed to foretell the fate of the messiah as suffering servant.
