In this essay, I will argue that justice is a matter of subjects. It is a matter of the subjects because it concerns about who creates justice at a historical juncture. It is also a matter of relationship among the various types of the subjects. Authentic subjects are the agents maximizing a new possibility in historical circumstances. They are those prophet Amos envisioned to appear in history: the ones who let “justice roll down like water” in history (Amos 5:24). They are bearers of history, who break up the situation where oppression and injustice prevail, and create a situation of new possibilities. They take part in a historical event, and are faithful to its truths. They participate in immortality by being faithful to truths in history, which bring about justice and peace.
