Christology means a doctrine or understanding concerning the person or nature of Christ. In the New Testament writings it is frequently conveyed through the titles applied to Jesus. Most scholars agree that "Son of God" is the most important of these titles in Mark. It appears on the lips of God himself at the baptism and the transfiguration, and is Jesus' own self-designation (Mark 13:32). These and other instances provide reliable evidence of how the evangelist perceived Jesus, but it is not clear just what the title meant to Mark and his 1st century audience. Where it appears in the Hebrew scriptures it meant Israel as God's people, or the king at his coronation, or angels, as well as the suffering righteous man. In Hellenistic culture the same phrase meant a "divine man", a supernatural being. There is little evidence that "son of God" was a title for the messiah in 1st century Judaism, and the attributes which Mark describes in Jesus are much more those of the Hellenistic miracle-working "divine man" than of the Jewish Davidic messiah.
