At the moment that humanity is going through a change of time, diagnosed in different ways and even antagonistic, with different worldviews that advocate its truth often absolutely, not rarely fundamentalist, Christian churches must respond to the challenge of presenting God, revealed by Jesus Christ, to the human being who lives in the urban context. Urban Ministry is challenging because the pastoral workers face an acute cultural diversity. The confusing process of globalization that seeks to produce a culturally homogenous society, paradoxically has produced multiple identities, with multicultural aspects. The cultural horizon of receivers of the Word of God in the urban environment is increasingly complex, affected by a sharp multiculturalism. In this urban context the pastoral workers face in contemporary times with people linked to underground urban tribes. The cultural horizon of these receptors is the underground culture. Announce the Good News of Jesus Christ to those people linked to underground urban tribes implies that pastoral agents know how to distinguish clearly between Faith and Culture seeking to discern between what actually belongs to the core of the Revelation and it s historical cultural brand. So the bottom line of this thesis is related to its propose to construct a inculturated evangelistic matrix and based in this matrix offer an evangelistic project that enable Christian Churches to present the Good News of Jesus to the Underground Culture. It is essential that the Christian churches leave the evangelistic matrix of domination and exclusion built throughout the history of Christianity. The thesis organisation was built around three chapters. The first chapter, nominated as the social-cultural approach, proposes an analysis of the socio-cultural references with the aid of multidisciplinary social sciences. The second chapter, corresponding to the theological approach, analyses the theological references in search of an elaboration of the concepts of evangelism, mission and inculturation meant for the construction of an evangelistic inculturated matrix. The third chapter refers to the pastoral approach. Proposes an evangelistic-missionary project in underground urban environments.
