Latin America contains some of the most overcrowded, corrupt, and violent prison systems on earth. The numbers are staggering. Brazil’s prison population exceeds 800,000 in facilities designed for fewer than half that number. Venezuela’s detention centers operate at over 200% capacity. Mexico’s federal and state prisons are rife with cartel influence, extortion, and summary violence. And Chile—the country I know most intimately, having spent six years inside its penal system—combines European pretensions of civilization with conditions that would shock any honest observer from the developed world.

I write this chapter not as a detached academic surveying data from a comfortable office but as a man who lived the reality. I ate the food. I even slept on the ground at times. I navigated the corruption, the gang politics, the religious charlatanism, and the daily indignities that characterize incarceration in a Latin American nation. What I discovered—confirmed by a growing body of scholarly research—is that the Gospel of Jesus Christ is the single most powerful force for transformation operating inside these broken systems, and yet the form in which the Gospel is most commonly delivered in Latin American prisons is often a distortion of the faith once delivered to the saints.

This chapter surveys the landscape of prison ministry across the continent, examining both the remarkable successes and the serious theological and institutional challenges that confront anyone who would bring sound, biblical Christianity into these environments.

Brazil’s APAC Model: A Revolutionary Experiment

The most significant institutional innovation in Latin American prison ministry originated not from a government bureaucracy or an international NGO, but from a group of Catholic Christians in São José dos Campos, São Paulo. In 1972, a lawyer named Mário Ottoboni founded the Associação de Proteção e Assistência aos Condenados—the Association for Protection and Assistance of the Convicted, known by its Portuguese acronym APAC.1 The first APAC prison facility opened later in Itaúna, Minas Gerais, which is why most people tend to associate APAC with that city and state. Chile’s institutionalized system, also known as APAC, establishes its own cell blocks, such as 41 in Rancagua and 103 (now 104) in Valparaíso.

The APAC model is revolutionary in its simplicity. Its foundational premise is that prisoners can be transformed through love, trust, and discipline administered not by the state but by the community. APAC facilities are operated by community volunteers and by the prisoners themselves, who assume responsibility for cooking, cleaning, maintenance, and—most critically—mutual accountability. There are no armed guards within the facility, which is true in every cell block in Chile. Security is maintained through the social bonds created by the program’s structure and the surrounding community's investment.

The twelve elements of the APAC methodology include community participation, the recovering [prisoner] helping the recovering [prisoner], work, religion, legal assistance, health care, human valorization, the family, the volunteer, the Center for Social Reintegration (CRS), merit, and the “Journey of Liberation with Christ” (Jornada de Libertação com Cristo)—a spiritual retreat adapted from the Catholic Cursillo movement. Religion is not incidental to the model; it is the animating force. Ottoboni (2000) understood what secular criminologists have been slow to acknowledge: that lasting behavioral change requires a transformation of the heart, and the heart is the domain of the spiritual, not the bureaucratic.2

The results speak for themselves. Over seventy APAC facilities now operate across Brazil, and the recidivism rate for APAC graduates is approximately 15%, compared to roughly 70% in Brazil’s conventional prison system.3 These numbers are not merely impressive—they are an indictment of the conventional approach to incarceration, which warehouses human beings in conditions of extraordinary violence and degradation, without fostering marketable job skills and a desire to work for a living, and then expresses surprise when they return to crime upon release.

From a Reformed perspective, the APAC model raises interesting theological questions. Its Catholic origins mean that the religious content includes elements—Marian devotion, sacramental theology, the Cursillo retreat format—that a Protestant, and certainly a Baptist, would regard as deficient. But the structural insight is sound: that community, accountability, meaningful work, and spiritual transformation are more effective at reducing criminal behavior than concrete walls and armed men. The challenge for evangelical Christians in Brazil and elsewhere is not to reject the APAC model but to build upon its structural insights while correcting its theological deficiencies. In Chile, APAC is dominated by Evangelicals and, therefore, the perceived Catholic shortcomings are avoided, although other severe problems still exist due to carnal Christian teaching, easy believism, and theological ignorance.

Evangelical Cells in Brazil’s Penal System

While the APAC model represents an institutional alternative to conventional incarceration, a parallel phenomenon has emerged organically within Brazil’s conventional prisons. Evangelical churches—predominantly Pentecostal—have established what scholars describe as “cells” within the penal system, creating distinct spaces that function as islands of order within otherwise chaotic environments.

Camila Caldeira Nunes Dias’ (2008) research on religion and violence in São Paulo’s penal system documents the dominance of evangelical churches—predominantly Pentecostal—as the principal religious presence in prison facilities, far outweighing other religious groups in their on-the-ground prison ministry footprint.4 These evangelical cells serve as what Thompson (2022) terms “infrastructure” within the penal system in Rio de Janeiro, providing services that the state has manifestly failed to deliver: literacy education, drug rehabilitation, conflict mediation, and spiritual counsel.

The physical differences between evangelical cells and the general prison population are immediately visible. Eva Scheliga’s ethnographic work on Pentecostalism in Paraná state prisons confirms what any visitor would observe: the evangelical wings are cleaner, brighter, and better maintained.5 Inmates in evangelical cells maintain their spaces with a discipline that reflects their spiritual commitments—or, more cynically, their desire to signal those commitments to prison authorities who grant privileges accordingly. Scheliga documents the complex negotiations between religious identity and institutional survival, noting that conversion in prison is never a purely spiritual event. It is also a social and political act that positions the convert within a web of obligations, protections, and expectations.

This observation should not trouble the biblically literate Christian. The parable of the sower (Matthew 13:3-23) teaches us that seed falls on various types of ground, and not every apparent conversion produces lasting fruit. Some men enter the evangelical cells because the Holy Spirit has genuinely convicted them of sin. Others enter because the cells are safer, cleaner, and more orderly than the alternatives. Still others enter for strategic reasons—to signal disengagement from criminal networks, to access privileges, or to position themselves favorably for parole. The task of the minister is to sow faithfully and to trust God with the harvest.

Chile: Personal Experience and Empirical Evidence

Chile holds a particular significance in my analysis for obvious reasons. I spent almost six years in the Chilean penal system, and during that time I observed, participated in, and was profoundly shaped by the intersection of faith and incarceration in that country.

The Chilean prison system operates at over 131% capacity, a figure that masks enormous variation between institutions. Some facilities in Santiago are packed well beyond 200% capacity, while newer facilities in smaller cities may approach their design limits. The consequences of this overcrowding are predictable: violence, disease, inadequate nutrition, and a pervasive atmosphere of tension that corrodes the mental health of inmates and staff alike.6

Recent empirical research has confirmed what I observed experientially. Andrés Barrios-Fernández and Jorge García-Hombrados published a remarkable study in the Journal of Labor Economics demonstrating that the opening of an evangelical church in the neighborhood where a released prisoner returns to live reduces twelve-month reincarceration rates among property crime offenders by eleven percentage points—a drop of about eighteen percent in the probability of returning to prison for this group. The authors find smaller and less precise effects for more violent offenses. The mechanism, as they argue, is primarily the social support and accountability structure that evangelical churches provide rather than religious conversion per se—which suggests that any local institution providing comparable social infrastructure could play a similar role, but as a matter of historical fact in Chile, evangelical churches are the institutions doing this work at scale, and at a fraction of the cost of any state intervention.7 This finding shows an extraordinary effect size in the social sciences: educational interventions and most employment programs fall prey to the achievements wrought by churches’ direct spiritual and social support, coupled with the indirect effect of connecting released prisoners to a community that provides accountability, employment networks, and a prosocial identity.

Reyes-Quilodrán and Guzmán, two researchers at the Law School of the Pontificia Universidad Católica de Chile, published a 2022 study in Religions directly addressing this question. They conducted in-depth interviews with 174 male inmates from Santiago Sur and Santiago 1 prisons—87 Evangelicals matched against 87 non-Evangelicals selected through proportional random sampling—and used principal component analysis and content analysis to compare the two groups. Their findings, in their own words, indicate that “evangelical inmates in Chilean prisons are less violent, more likely to follow internal jail regulations, and more cooperative with professionals and officials.” They further document that evangelical inmates inside Chilean prisons organize themselves into a highly structured, pyramid-shaped social community whose emotional support and daily routine are fundamental to their lower violence rates—a finding consistent with the broader international literature on religion and prison behavior. This carries particular weight in the Chilean context, where the evangelical community has grown from a negligible minority to approximately 17% of the national population over the past half-century.8

My own experience confirms and complicates these findings. The evangelical inmates I encountered in the Valparaíso Penitentiary, to a slightly lesser extent in Rancagua and Casablanca, were, on the whole, more disciplined, more cooperative, and less violent than the general population. But the theology they professed was, in most cases, a variant of theologically errant Pentecostal teaching that bore little resemblance to the faith of the Reformers or the confessions of historic Christianity. The “church” inside the prison was dominated by men who claimed direct revelation from the Holy Spirit, who spoke in tongues, who promised material blessings to the faithful, who let practicing homosexuals be members, and who exercised a form of spiritual authority that was more akin to the caudillo tradition of Latin American politics than to the servant leadership modeled by Christ.

Argentina: Evangelical Pavilions as Alternative Governance

Argentina presents perhaps the most striking example of religion functioning as an alternative governance structure within the prison system. In several Argentine prisons, entire pavilions—cellblocks housing hundreds of inmates—have been organized around evangelical religious practice, creating self-governing communities that operate according to religious rather than secular or criminal norms.

These evangelical pavilions, or pabellones evangélicos, emerged in the 1980s and 1990s as a pragmatic response to the Argentine state’s inability to maintain order within its own prisons. When the state cannot govern, alternative power structures inevitably arise. In most Latin American prisons, these alternative structures are criminal gangs, cartels, and mafias that impose their own brutal order through violence and intimidation. Empirical evidence supports this picture starkly. Fondevila and Vilalta-Perdomo’s 2024 survey of 5,700 inmates across six Latin American countries found, counterintuitively, that the most overcrowded and worst-conditioned prisons in the region (Brazil and El Salvador) had the lowest rates of inmate-on-inmate violence—not because conditions were tolerable, but because dominant gangs had achieved sufficient internal control to suppress disorder for their own purposes.9 The state's absence had been filled by an unelected, unaccountable, and brutally efficient criminal sovereignty. The evangelical pavilions represent a different model: self-governance under a religious framework, with pastors and deacons functioning as de facto administrators, mediators, and disciplinarians—as noted by Míguez (2008) and Algranti (2018).10

The inmates in these pavilions maintain a daily schedule organized around prayer, Bible study, worship services, and communal work. Alcohol, drugs, and weapons are prohibited and—remarkably—largely absent. Disputes are resolved through pastoral mediation rather than violence. The physical conditions, as in Brazil’s evangelical cells, are markedly superior to those in the general population wings.

The Argentine case raises important questions about the relationship between religious conversion and institutional survival. Critics argue that many inmates convert strategically, adopting the external forms of evangelical piety to escape the violence and squalor of the general population. This is undoubtedly true in some cases. But the same criticism could be leveled at any church in any context. The question is not whether every conversion is genuine, but whether the framework itself creates conditions for genuine conversion. On this count, the evidence is affirmative.

The theological implications are significant. When the government fails to serve the public interest, as it certainly does in the criminal justice and penal system, something must fill the vacuum. In most cases, that something is organized crime. In the Argentine evangelical pavilions, it is organized religion—and whatever one may say about the theological depth of Argentine Pentecostalism, the empirical results are incontestable. Violence is lower, health outcomes are better, and the atmosphere permits something that the general population wings do not: the possibility of reflection, repentance, and genuine encounter with the Word of God. The prisoner who enters an evangelical pavilion out of strategic self-interest may, by the sovereign grace of God, find himself confronted with a truth he did not seek. “I was found of them that sought me not; I was made manifest unto them that asked not after me” (Romans 10:20, quoting Isaiah 65:1). God is not constrained by the impurity of human motives. He uses them.

Other Latin American Models: Bolivia, Paraguay, and Belize

The institutional landscape across the rest of Latin America offers further variations on the same fundamental theme—state failure producing alternative governance—each with its own combination of humane and grotesque features. Bolivia’s San Pedro prison in La Paz is the most photographed and least understood example. State authorities effectively ceded internal governance to the inmates themselves decades ago. Wives and children commonly live inside the prison with the convicted men; cells are not assigned by the state but bought, sold, and rented within an internal property market; and inmates run restaurants, internet cafés, taxi services, hairdressers, laundries, and small retail shops as legitimate businesses serving fellow prisoners and the steady stream of foreign visitors who, despite an official 2009 ban, continue to enter the facility through inmate-arranged tours. Rusty Young’s journalistic account, Marching Powder (2003), brought the system to international attention.11

The humane elements are real and ought to be recognized: family preservation, meaningful work, social structure, and a noticeable absence of the institutional dehumanization that defines most Latin American prisons. The dark side is also real and ought not to be sentimentalized: cocaine has historically been produced inside the prison walls, children grow up immersed in a criminal economy, and the entire arrangement depends on a complete abdication of state custodial responsibility that most Reformed political theology cannot ultimately approve—though libertarian historic Baptist churches, who reject the revitalized Divine Right of Kings doctrine held by most contemporary Reformed Baptists,12 would not object on those structural grounds (their objection would lie elsewhere, in the specific moral failures of the San Pedro arrangement rather than the absence of state custody). Bolivia’s San Pedro is what happens when the state surrenders so thoroughly that the inmates themselves must construct a society from scratch.

Paraguay’s Tacumbú National Penitentiary in Asunción presents a related but distinct picture. Operating at well over two hundred and fifty percent of design capacity, with several thousand inmates crammed into space designed for hundreds, Tacumbú functions through an informal economy in which family members and external vendors enter daily to supply, support, and partner with prisoners running stalls, food carts, and small retail establishments inside the perimeter. The Netflix documentary Inside the World’s Toughest Prisons devoted its Season 4 premiere in 2020 to the facility, capturing both the anarchic resourcefulness and the brutal violence that coexist there.13 Tacumbú is not a model of rehabilitation; it is a model of how human ingenuity adapts to the absolute failure of state custodial institutions—and it should be understood as such, neither romanticized nor dismissed. The guards are a token presence, and one might wonder why there is no uprising and mass escape. The actual order at Tacumbú is maintained by inmate hierarchies, family-supplied informal economies, and pavilion bosses—a vivid corroboration of Fondevila and Vilalta-Perdomo’s broader finding that gang-governed Latin American prisons paradoxically register lower levels of inmate-on-inmate violence or uprisings than their staffing levels alone would predict (Fondevila & Vilalta-Perdomo, 2024; see note 9). It is actually an example that confirms libertarian theory: markets may be imperfect, but state intervention is worse; or anarchy may be bad, but the state is abysmal.

Belize Central Prison at Hattieville (if we may, for geographical proximity, include it in Latin America) is the most genuinely promising of these alternative models, and the one Reformed Christians ought to study most carefully. Since 2002, the facility has been managed under contract by the Kolbe Foundation, a Belizean non-profit whose name honors the Catholic martyr Maximilian Kolbe but whose programming has consistently drawn from both Catholic and evangelical Protestant streams of the Christian faith. Researchers from the University of Indianapolis have documented a substantive shift under Kolbe management away from punitive warehousing toward genuine rehabilitation, including the unusual and biblically apt practice of hiring former offenders—and even current inmates—in carefully structured roles to participate in the work of prison reform itself.14 The Belize model is not a doctrinally Reformed Christian model (it could not be, given its institutional founding), but it demonstrates what becomes possible when the state surrenders the custodial monopoly to a genuinely Christian non-profit committed to the dignity of incarcerated persons. The contrast with state-run facilities elsewhere in Central America—a region drowning in gang violence and overcrowding, including El Salvador’s overcrowded prisons and Draconian conditions—is stark and instructive.

What unites these three cases with the Brazilian, Chilean, and Argentine cases discussed earlier is a single underlying truth: the state has comprehensively failed at its custodial responsibilities across Latin America, and into the resulting vacuum has rushed every imaginable alternative—criminal gangs, evangelical pavilions, Catholic-led private rehabilitation, family co-residence, inmate-run economies, and combinations of all of the above. Where the state has failed, and a genuinely Christian institutional response has emerged, results improve dramatically. Where the state has failed, and only criminal alternatives have emerged, the results are predictable: drugs, violence, and the destruction of human dignity on an industrial scale. The pattern points toward a clear policy implication that no Reformed Christian should hesitate to draw: the state’s monopoly on incarceration is itself a major contributor to the failures of incarceration, and any serious reform agenda will involve transferring substantial custodial authority to non-state, non-criminal alternatives.
