The aim of the article is to outline the history of the mission of the minjung church from 1983 to 2005 and to identify its new missionary tasks in a changed world. At the end of the cold war, the minjung movement in general, the minjung mission in particular, seemed to be unnecessary any more. After the economic crisis of 1997, however, the minjung mission played an important role for taking care of victims of the structural adjustment programs of many corporations, and for establishing alternative communities. Its history divides into four periods: the formation period (1983-1987), the development period (1988-1992), the transformation period (1993-1997), and the professional period (1998-2005). Each period deals with its socio-economic, political, cultural background and minjung mission’s main contents, characteristics, and limitation. The history of the mission of the minjung church is interpreted by the results of the social biographies of 26 minjung pastors. According to their social biographies, minjung pastors changed themselves in the process of the minjung mission rather than changed the minjung. They rediscovered the importance of the Bible and religion in relation to the social change. Also they found negative aspects of the minjung. They regarded spirituality and life as pillars for the forthcoming minjung mission. Some reflections on mission of the minjung church was carried out through analysing the relationship between faith and ideology, the dilemma of identity-involvement, positive understanding of religion, understanding of minjung, and theories of community organization and conscientization. In a changed world, spirituality, the minjung and life are identified as new tasks for the minjung mission.
