When it comes to political participation, Pentecostals were in the shadow of other Christian groups for a long time. As minority groups centered on doctrinal disputes, they had no pretensions in the political arena or they already felt represented. The perception changed with the increase in the number of supporters in the second half of the 20th century – that is, more electoral strength –, with the changes in the traditional society model and with the political opening after the weakening of the military regime in the mid-1980s, with the Constituent Assembly. They begin a more organized and corporate action, which indicated the emergence of a religious agenda. The question that guides the article is: What are the consequences of turning the relationship between Church and Politics into a power project centered on corporate interests? What place would churches have in national political participation? The objective is to think about the Church s engagement in politics beyond the uncritical alignment that is seen in many sectors today. As a methodological path, it will be based on the work of Pentecostals, although refl ections may reach other Churches.
