In the age of neo-liberal, global capitalism various kinds of human communities are continuously deconstructed and the creation is severely demolished. Under this circumstance diakonia should overcome the dichotomy of giver and receiver, which means the Baal type of diakonia theology. On the one hand, the giver always wants to be a giver/stronger, so that s/he has never accepted help from others and s/he denies the justification by faith. On the other hand, the receiver could be a crippled inside by negating the possibility of becoming a giver. However, there is an alternative model of diakonia, alternative community model. This model is an “alternative” to the neo-liberal, global capitalism and an alternative “community” model rather than an alternative individual one. In this paper, diakonia is defined as a salvation act through establishing faith community aiming at the Kingdom of God. This thesis aims at suggesting some cases of diakonia of Korean Christianity as alternative community models. There are four types of alternative communities: community type (Pulmu school and its local community), church type (Jagun church), church-community type (Baegun church and Hanmaum community, and Multicultural church and the Borderless Village), and NGO type (Youngdungpo-UIM based credit cooperative, Kwanak Self-support Center, and Ulsan Social Enterprise). The missiological significance of these alternative communities is such as: their aim is the kingdom of God and church should be a sign-community orienting toward the kingdom of God; their model is the koinonia of trinity; the close relationship between diakonia and koinonia; members of alternative communities are the little, outcasts, and minjung; we learn from them that the mission paradigm shifts from social mission to life mission; the center of the life mission is economy so that alternative economic community is very important; the importance of spirituality, concentrating toward the inner mind in oder to serve others(people and the creation). Though we are looking for alternative community models, they are particular ones, fit to their own socio-political, cultural and economic traditions and systems. However their missiological significance shows us some contour of a universal picture.
