Carlyle has said that the greatness of a character is measured by the contrasts it exhibits. The words of Jesus we have been studying, taken in their entirety and in their context, show the contrasts between knowledge and humility, between power and humility, and, when the woes on the cities are contrasted with the invitation, "Come unto me," between sternness and tenderness. When Socrates was told by the oracle that he was the wisest of men, he was in perplexity for a time, but finally decided that he was wise because he recognized his own ignorance. In His knowledge of the Father and in the mystery of His own person, Jesus places Himself on an equality with God. Yet this knowledge did not "puff up." There was no need with Jesus as with Peter for the moment of spiritual insight to be followed by a rebuke for presumption; nor did He need like Paul, because of the greatness of the revelation, to have the thorn in the flesh lest He be exalted above measure. These contrasts, not found in any other historical character, are a self-authenticating feature of the words of Jesus. All of His actions, in fact, and all of His attitudes towards men, whether they were friends or foes, and all His words, whether of compassion, forgiveness, warning or indignation, were those of a "Prince and a Saviour," a Prince in majesty and power and a Saviour in pity. Both deeds and words showed that union of qualities which it would be impossible to invent, "the self-assertion of the great example of humility." IV. THE DILEMMA OF HISTORICAL CRITICISM
