This paper deals with the notion of reconciliation in sangsaeng theology for Korean reunification. Sangsaeng theology s central concept, haewonsangsaeng (resolution of resentment and life-sharing), makes it clear that reunification means reconciliation and to accomplish it Koreans must focus on the resolution of accumulated resentment - han. Haewon-sangsaeng enables people to put all grudges and acrimonious relationships, to forgive others, and to cooperate with them in order to live in harmony and peace. Haewon-sangsaeng is central to an ethical-theological discourse of reconciliation. Reconciliation in sangsaeng theology is to come through the resolution of resentment or han and to construct an ethics of Korean reunification. Reconciliation focuses on building together a shared vision of the future. Reconciliation is not so much about the past as it is about the future. Reconciliation is to move beyond revenge and hatred. There can be no communion in the world if there is no reconciliation, that is, if there is no healing of the divisions that exist in the world. Reconciliation is a key element in the work unity. Reconciliation enables us not only to counter in every way possible enmity and opposition, but actually to foster openness and understanding of differences. In thinking of the notion of reconciliation, I am reminded of a poem by Kim Min Kee, Two Fish, in which a fish suffers because of the death of another fish. Two fish mean the divided South Korea and North Korea. Though they are opposite each other, they cannot exist without the other. While they are exclusive of each other, at the same time, they are complementary to one another. This is a creative relationship rather than a destructive one. The two fish are not different but the same. In a sense, an ethics of reconciliation is not about ideas but about a way of living, of moving from haewon to sangsaeng.
