The research is linked to the Graduate Program in Theology at PUC-Rio in the area of Systematic-Pastoral Theology, line of research: Religion and Modernity; and linked to the research project Themes on the Church and the Dialogues. The beginning of the 20th Century introduced to the world the current pentecostal movement, which it expanded considerably in Christianity, and its way of missionary work has awakened the attention of many researchers. In this thesis is analyzed the mission of the Foursquare Church, which integrates the movement, both in terms of its historical participation and in Theology. The research sought a theologian who discussed pneumatological themes and the mission Theology, finding in José Comblin an interesting theoretical reference to compose a dialogue about the mission and the Holy Spirit. This prominent theologian, in addition to deal with relevant themes to the mission of that denomination, also served as a missionary, reflecting from the act itself. It s proposed here the ecumenical dialogue, as it is a pentecostal practice in dialogue with an exponent of the Catholic Theology. The hypothesis research is that the growth of the Foursquare Church in Brazil is related to its mission by the laypeople. The mission for the Foursquare Church begins with an evangelization of thaumaturgical proclamation, for the healing of individuals. We see that for Comblin, the mission has a liberation character of the human being. At this point, the two notions of mission can dialogue. It is observed that nowadays the reflection of Foursquare Church is opening up from the healing of the individual to also have the care of the human being and everything that concerns to life, such as Ecology and social differences.
