In the paragraph we are considering a very needful reminder is given us that the Jews of our Lord’s time used the terms “God” and “Son of God” in a loose and inexact manner. Where the sense was not likely to be misunderstood, they did not scruple to apply these terms to officials and dignitaries. The angels they called sons of God; their own judges they called by the same name. The whole people considered collectively was called “God’s son.” And in the 2nd Psalm, speaking of the Messianic King, God says, “Thou art My Son: this day have I begotten Thee.” It was therefore natural that the Jews should think of the Messiah not as properly Divine, but merely as being of such surpassing dignity as to be worthily though loosely called “Son of God.” No doubt there are passages in the Old Testament which intimate with sufficient clearness that the Messiah would be truly Divine: “Thy throne, O God, is for ever and ever;” “Unto us a Child is born ... and His name shall be called the Mighty God;” “Behold the days come that I will raise unto David a righteous Branch, and this is the name whereby He shall be called, Jehovah our Righteousness.” But though these passages seem decisive to us, looking on the fulfilment of them in Christ, we must consider that the Jewish Bible did not lie on every table for consultation as our Bibles do, and also that it was easy for the Jews to put a figurative sense on all such passages.

In a word, it was a Messiah the Jews looked for, not the Son of God. They looked for one with Divine powers, the delegate of God, sent to accomplish His will and to establish His kingdom, the representative among them of the Divine presence; but they did not look for a real dwelling of a Divine Person among them. It is quite certain that the Jews of the second century thought it silly of the Christians to hold that the Christ pre-existed from eternity as God, and condescended to be born as man. “No Jew would allow,” says a writer of that time, “that any prophet ever said that a Son of God would come; but what the Jews do say is that the Christ of God will come.”

This circumstance, that the Jews did not expect the Messiah to be a Divine Person, throws light upon certain passages in the Gospels. When, for example, our Lord put the question, “What think ye of Christ? Whose Son is He?” The Pharisees promptly answer, “He is the Son of David.” And, that they had no thought of ascribing to the Messiah a properly Divine origin, is shown by their inability to answer the further question, “How then does David call Him Lord?”—a question presenting no difficulty at all to any one who believed that the Messiah was to be Divine as well as human.[37]
