3. If, nevertheless, the Jews have a mission, is it perhaps this: to rehabilitate the prophetic ideal of social justice? Is it not social justice that the world is crying for today? Were not the prophets of Israel the great preachers of righteousness in the sense of social justice? Did they not affirm that religion consists in justice and in its concomitant mercifulness, but above all in justice? Did not Isaiah say: “When ye come to tread my courts, who has demanded this of you? Go wash you, make you clean. Put away the evil that is in your hands. Cease to do evil; learn to do good.” And later on, “That ye let the oppressed go free, and that ye break every yoke.” These are solemn, marvelous words assuredly! They have been ringing down through the ages, and still find their echo in our hearts. And yet the justice idea of the prophets is inadequate to serve the purpose of social reconstruction today. To go back to it would mean repristination, not renovation. It is sound as far as it goes, but it does not go far enough. It is negative, rather than positive; it is based on the idea of non-violation. What we require today is a positive conception, and this implies a positive definition of that holy thing in man that is to be treated as inviolable. To the mind of the prophets justice meant chiefly resistance to oppression, since oppression is the most palpable exemplification of the forbidden violation. The prophets in their outlook on the external relations of their people stood for the weak, the oppressed, against the strong, the oppressor. They stood for their own weak little nation, the Belgium of those days, against the two over-mighty empires, Egypt and Assyria, that bordered it on either side. In the internal affairs of Israel they espoused the cause of the weak against the rich and strong: “Woe unto them that add house to house and field to field, that grind the faces of the poor.” Ever and ever again the same note resounds, the same intense, passionately indignant feeling against violation in the form of oppression. But this aspect of justice, as I have said, is the negative aspect,—inestimably important, but insufficient. Where oppression does not occur, have the claims of justice ceased? Is there not something even greater than mere non-infringement, greater than mercifulness or kindness, which in justice we owe to the personality of our fellows, namely, to aid in the development of their personality? Righteousness, yes, by all means,—but does the righteousness of the prophets of Israel exhaust or begin to exhaust the content of that vast idea?
