Brazil’s religious politics did not shift through a simple handoff from progressive Catholics to conservative evangelicals. Liberation theology helped build grassroots networks whose members later organized through parties and social movements; meanwhile, changes in the Catholic Church overlapped with the expansion of Pentecostal and neo-Pentecostal churches and their political networks. These histories help explain the political landscape, but affiliation alone does not tell us how anyone votes.
How did liberation theology influence Brazilian politics?
Emerging in the 1960s and 1970s, liberation theology connected Christian faith with concern for poverty and social justice. Under Brazil’s military rule, progressive bishops and Basic Ecclesial Communities (CEBs) gave workers and peasants local settings in which to meet, discuss shared conditions, and organize. These communities mattered not only as religious institutions but also as places where people could develop relationships and political capacity.
As political openings widened during democratization, some activists carried that experience into secular organizations. Accounts of the period connect former CEB participants and networks with the Workers’ Party (PT), the Landless Rural Workers’ Movement (MST), and labor organizing. The legacy was therefore partly organizational: people and skills built in church settings could continue to shape public life beyond the church.
That route differs from saying that liberation theology directly created a political party or determined its supporters’ votes. It describes how institutions helped people organize, and how activists later worked through a wider political field.

Why did evangelical churches grow in Brazil, and how did that change the political landscape?
Geoffrey Pleyers’s 2020 analysis identifies two developments that overlapped in the 1980s: a conservative turn in the Catholic Church, including attacks on liberation theology and its practices, and the concurrent rise of conservative neo-Pentecostal churches. He describes activists from CEBs as maintaining progressive commitments through established movements and organizations, while conservative churches became important settings for political organization in some communities.
One account of the change emphasizes the local roles churches could play, particularly in neighborhoods underserved by the state: building community, offering practical support, and developing media and political networks. It contrasts liberation theology’s emphasis on collective structural critique with more individualized approaches centered on conversion, discipline, and material advancement. That is an analytical contrast, not a description of every church or member. Churches vary, and people may participate for reasons that do not map neatly onto a political ideology.
Rank #2
The broader point is not that Pentecostal institutions simply replaced Catholic ones. Catholic communities and their political legacies persisted as evangelical affiliation expanded; institutional change, political organizing, and demographic change did not happen as a single, clean transfer.
How did the two kinds of organizing differ?
| Dimension | Liberationist Catholic networks | Pentecostal and neo-Pentecostal networks |
|---|---|---|
| Institutional setting | Basic Ecclesial Communities and progressive bishops within the Catholic Church | Church congregations and, in some cases, organizations with political and media networks |
| Community role | Local spaces where workers and peasants could meet and organize under military rule | Community and practical support, including in neighborhoods underserved by the state, as described in the title-matched account |
| Routes into public life | Activists later connected with parties, labor organizing, and social movements, including the PT and MST | Churches and representatives increasingly entered electoral politics after 1986; forms of engagement and alliances differed by church and election |
| Political emphasis in the cited analysis | Collective critique of structural conditions | In some accounts, more individualized themes of conversion, discipline, and material advancement |
These are broad historical contrasts, not fixed traits of all Catholic or evangelical institutions. They describe organizational settings and tendencies discussed by the cited authors, not a reliable shortcut for predicting an individual’s beliefs or vote.

Did Pentecostals support Bolsonaro or the right as a bloc?
No. Pentecostal political involvement developed over time, and church endorsements have varied. Pew Research Center’s 2006 historical overview describes many Pentecostals as politically apolitical in the early twentieth century, followed by increased church and representative participation after the 1986 elections for a Constituent Assembly. It discusses political debates involving religious freedom, religious teaching in public schools, and social questions. That history establishes a chronology through 2006; it is not evidence of present-day voting patterns.
The same historical account illustrates why a single-bloc explanation fails: in 2002, leaders of the Universal Church and Reborn in Christ supported Luiz Inácio Lula da Silva, while the Assemblies of God and Foursquare Gospel supported José Serra. These examples do not describe every congregant or settle how churches behaved in later elections.
A study of the 2022 election examined religious leaders’ messages and reported voting using telephone interviews with 1,500 voters aged 16 and over, conducted from January 17 to February 14, 2023. Its subject is whether respondents heard leaders support Jair Bolsonaro and how they reported voting. Such evidence can help distinguish exposure to a message from a reported vote; it does not justify assuming that every congregant followed a leader’s position.

IBGE’s preliminary sample results from Brazil’s 2022 Census report religious affiliation among residents aged 10 and over. The figures describe declared affiliation, not religious practice, political views, leaders’ influence, or vote choice.

| Declared affiliation in 2022 | Share of residents aged 10 and over |
|---|---|
| Catholic | 56.7% |
| Evangelical | 26.9% |
| No religion | 9.3% |
| Umbanda and Candomblé combined | 1.0% |
These preliminary sample figures were released by IBGE in 2025. They show that Catholic affiliation remained substantial alongside evangelical growth, no-religion identification, and religious diversity; they should not be read as a two-group exchange or as a political tally.
For longer context, Pew Research Center’s 2013 report, drawing on Brazilian census data, says Catholic affiliation fell from 74% in 2000 to 65% in 2010, while Protestant affiliation rose from 15% to 22%. In that report, “Protestant” is a broad category that includes mainline, evangelical, Pentecostal, and independent neo-Pentecostal groups, so it is not interchangeable with IBGE’s 2022 “evangelical” category. Pew also reports Pentecostal and neo-Pentecostal affiliation rising from about 6% in 1991 to 13% in 2010 under the census categories it analyzed; that is a historical trend, not a current estimate.
What can religion explain about the Brazilian right?
Religion helps explain some of the institutions, networks, public messages, and political identities through which Brazilians have organized. It does not, by itself, explain Brazil’s rightward political shifts or establish that religious affiliation caused a particular election result. Pleyers frames the Catholic Church’s conservative turn and neo-Pentecostal growth as “one of [the] roots” of the change, leaving room for other political and social causes.
It is useful to keep three things separate: the capacity of an institution to mobilize people, the endorsements or messages offered by religious leaders, and individual voters’ choices. Each requires its own evidence. A reported causal estimate linking replacement of bishops to PT vote share has appeared in a contemporary account, but without the primary study checked it cannot be treated here as established evidence.
