Resumen:
This paper focuses on the dialog between the work of the Frente Parlamentar Evangélica [Evangelical Parlamentary Front], Apoio à vida (FPE) [Support of Life] and Public Theology on themes related to social participation, within the broader scope of the relation between religion and society, as a specific way of approximating the churches of conversion leanings to the national political themes. The work is organized in three chapters, being the first about considerations of the FPE and it history and work, while the second brings characteristics and impressions with regard to the new configurations of the Evangelical world and the political debate on internet. Finally, in the third chapter, there are some considerations about the work of the FPE using Public Theology as a tool for reflective and critical considerations of the presuppositions lifted up as principles defended by the Evangelical parliamentarians gathered in the FPE.
