This Thesis was developed to approach issues related to the ecclesial power and the media actions. Taking into account the advance in the area of communications and the contemporaneous technology, questions arise concerning how these choices may act as tools for the announce of the Gospel. The question of the ecclesial power was also considered and an analysis of power was developed, in a neutral way, trying to answer questions on the influence of religion in society as well as the manner this action generates alternatives of power. The conclusion is that power may be exercised in a legitimate way, when it transforms itself in service. The steps developed in the dissertation were taken the following way: a conceptual analysis about the ecclesial power and its scope, whose study was done in a bibliographic way, by means of research on several books and on the findings of several theoretical writers. In addition, the theological aspects of power and of media communication were approached, as well as the way theology may act as reference to draw the themes on. Being a theological investigation, the approaches were based on the principles of theology, the ministry of Jesus was analyzed as a base, acting as reference to those who perform the pastoral media ministry and to those who postulate this service. As the research was being developed, a field research with four religious leaders who exercise the far-reaching media ministry took place. It is worth explaining that, in the course of this investigation, the lack of theoretical material to support those who exercise the media ministry was perceived. The conclusion of the dissertation, drawn on the analyses of the findings, points to certain neutrality of the ecclesial power, which may be used in a negative way as well as in positive one, depending on the character of the one who exercise it. Another point to be emphasized refers to the use of the media and the technology, as they tend to contribute legitimately and effectively in order help people.
