With all of his insistence upon absolute uprightness and truth-telling and plainness of speech, we find no hint of a lack of courtesy or kindness, or of diplomacy in the best modern American sense of that much-abused word. The direct, truth-telling, open diplomacy that is imperative upon a democratic government like the United States, where it is impossible to have secret treaties or for any great length of time even confidential understandings between nations that are not public in their character, is quite in accord with the teachings of Jesus; whereas the secret treaties such as those that led to grave misunderstanding on the part of the United States when it entered the Great War are directly contrary to the spirit and practice of Jesus' teachings. It is not sufficient to call such practice of a secret diplomacy "discreet," which would be proper; but often, as in the cases mentioned, where vital interests of others are involved, such treaties lead to direct deception, and, in consequence, to injurious practices. Indeed, it is often because of the unjust nature of such treaties that the attempt is made to keep them secret. In the farewell visit with his disciples just before his betrayal, Jesus showed them how throughout the period of their discipleship he had been gradually teaching them as they were able to understand. He had not taught them all his life principles to begin with, because they were not yet ready to receive all of the truth. And even in this last discourse, when he was rehearsing for the disciples the nature of his relations with them and their relations with the world, he still gave them to understand that only as they became equipped to receive the truth could all the truth be given them. "I have yet many things to say unto you, but ye cannot bear them now. Howbeit when he, the Spirit of truth, is come, he shall guide you into all the truth...." (John 16:12, 13). In his final words to them he expressed his conviction that he had already so put his principles of life and action into the minds of men that through their gradual fruition in the future there would be given unto us a new earth, a new society, and he concluded: "These things have I spoken unto you, that in me ye may have peace. In the world ye have tribulation: but be of good cheer: I have overcome the world" (John 16:33). His task had been completed. He was confident that his principles in time would conquer and give the world peace. IV. THE WORTH OF THE COMMON MAN: INDIVIDUAL RESPONSIBILITY The greatest single contribution that Jesus made to social and political science was his insistence upon the worth of the common man. That is practically a declaration of the moral equality of all mature individuals, rich and poor, bond or free, a declaration of their duty to make their own decisions on questions of right and wrong, and in consequence the recognition of the responsibility which each must bear for the conduct of his own life.
