In the O.T. the Messiah is revealed under various aspects, but chiefly four as follows:

1. King of Israel;
2. Servant of Jehovah;
3. Son of Man;
4. Son of God.

The four gospels harmonize with these and also there were four representative classes of people on the earth whose peculiar needs were met by these four aspects; namely,

1. Jews,
2. Romans,
3. Greeks,
4. and the Christian Church composed of believing representatives of all three.

1. Matthew wrote for the Jews and presents Jesus as the king of Israel;
2. Mark for the Roman presenting Him as the Servant of Jehovah;
3. Luke for the Greek as the Son of Man;
4. John for the Christian Church as the Son of God.

The first three are called Synoptics from two Greek words sun which means together and opsis which means a view because they present the same general view of Christ as distinguished from John's Gospel which presents a different view.
