Peace should be approached by inclusivism, consisted of politics, economy, international relationship, social welfare, community health care, education, and culture. For the current government of South Korea has been obsessed with ideology rather than national interests during the last five years, the relationship between South Korea and North Korea is in crisis. Theological foundations for reconciliation are truth, memory, repentance, justice, forgiveness, and love. The presupposition of reconciliation is to know what happened to the victim. The truth of the victim can be recognized through memory, that is the center of one’s identity. Repentance of the perpetrator is necessary for the process of reconciliation. In return the victim should forgive the perpetrator. In the whole process of reconciliation, love is a dominant factor. Theological foundations for peace are justice, reconciliation, nonviolence, just peace, and economic justice. Justice is the precondition for peace. And reconciliation is the way to peace. Nonviolence is the hope for peace. Just peace is suggested by the WCC as an alternative to the just war and pacifism. Economic justice is identified as an essence for peace. Tasks of the peace mission of the Korean Church for reconciliation and peace reunification of South Korea and North Korea are such as nonviolent communication, nurturing of the peacebuilders, the peace education for encouraging the culture of peace, the care for the victim of violence and programs for violence prevention, media as a peace messenger, the peace mission in the public area, and strategies of peace mission in the troubled areas. The peace mission should be approached by inclusivism and Christian realism as well. For practicing the peace mission the Korean Church can learn about important lessons from the various examples of the peace mission done by the member churches of the WCC during the Decade to Overcome Violence, from 2001 to 2010. The Korean Church is encouraged to study the precious experiences of the Peace Church (the Mennonites, the Quakers, and the Brethren Church) for enacting the peace mission.

Kang Man-Kil is the first historian to position overcoming of division and reunification of the Korean peninsula as the most important scholarly topic. The overall structure of his historiography is constructed of: first, gaining a penetrative historical perspective on the Age of National Division, and second, establishing a new historical framework that can overcome division. These two themes can be encapsulated into his term, ‘reunification nationalism’. ‘Reunification nationalism’ is the rightful guiding ideology for the Korean society, contributing to overcoming division and reunifying the nation. Kang’s reunification nationalism is meaningful in three ways: 1. It is an ‘alternative historiography’, in which the national united front movement based on negotiations between left and right wings since the colonial period is seen as the mainstream of national history. 2. It recognizes the entire Peninsula as one national unit and it is an ‘anti-divisionist historical perception’ that considers all Peninsula citizens to be agents of historical development. 3. All Peninsula citizens are seen to constitute one historical and cultural community, and it is meaningful as a ‘reunification theory’ based on peaceful, reciprocal and equitable methods. In sum, the above-mentioned three aspects of reunification nationalism form the basis of the details of Kang Man-Kil’s reunification nationalism, which is his ‘theory of equitable reunification’.
