Navigating the Future of Religion: Peter Berger’s Predictions

For much of the twentieth century, social scientists were fairly confident about religion’s fate: modernity would eventually push it to the margins of public life. Science, rationalism, and industrialization, they argued, would collectively drain society of its need for the sacred. Peter Berger was once among those who held this view. But in one of sociology’s more remarkable intellectual reversals, he later declared the secularization thesis “falsified” – and spent the latter part of his career building a far richer theory to explain why religion not only endured but surged back in a pluralistic, modern world.

The secularization thesis and Berger’s break with it 🔗

The secularization thesis, dominant in sociological thinking from the 1950s through the 1970s, held a simple proposition: modernization inevitably produces a decline of religion, both in society and in individual consciousness. Berger, like most of his contemporaries, broadly accepted this framework as a reasonable reading of the evidence. The assumption was that science, urbanization, and institutional differentiation would progressively hollow out religious belief, leaving faith as a residual, private matter at best.

It took Berger roughly two decades of comparative observation to conclude that the data simply did not support this picture. In a candid 2013 interview, he acknowledged that the world was “not heavily secularized,” with only two notable exceptions: Western and Central Europe, and an internationally mobile intellectual class. Beyond these, the rest of the world was – as he put it – massively religious, and in some regions more so than ever before. This honest recantation set the stage for a new theoretical framework.

Desecularization: religion’s unexpected comeback 🔗

In his landmark 1999 edited volume The Desecularization of the World: Resurgent Religion and World Politics, Berger formally coined the concept of desecularization. The term describes a resurgence or growth of religion after a period of secularization – a direct challenge to the assumption that religious decline is the universal destiny of modern societies. Rather than a clean, linear march toward secularity, Berger now saw the global religious landscape as deeply uneven, shaped by counter-secularizing forces operating alongside whatever secularizing trends were present.

Berger pointed to the increasing influence of conservative and evangelical churches in the United States, the Protestant upsurge across Latin America, militant Islam, and the role of religious institutions in democratic transitions in the former Eastern bloc as evidence that religion had assumed a new societal relevance – taking on fresh forms and functions rather than fading away. He rejected the secularization paradigm as Eurocentric, linear, and deterministic, and called for a new research agenda grounded in a global outlook.

Berger also noted something conceptually important: secularization at the societal level is not necessarily linked to secularization at the level of individual consciousness. Institutions could become more differentiated from religion while individuals retained – or even intensified – personal faith. This distinction would prove central to his later thinking.

The evangelical surge and religious vitality in the Global South 🔗

One of the most compelling empirical cases for Berger’s revised position came from the explosive growth of evangelical and Pentecostal Christianity across the Global South. According to Pew Research data, the Christian movements growing most rapidly are found primarily in the global South and East – and much of the energy behind that growth in countries like Nigeria and China has come from Pentecostal and Charismatic movements. These are not peripheral communities; they represent a seismic shift in the center of gravity of global Christianity.

Pentecostalism is reshaping Christianity numerically. The growing edge of the faith is now in the global South, not the West – and some observers describe what amounts to a reverse missionary movement, with Christians from Rwanda and Nigeria now evangelizing in the United States. In Brazil, evangelical churches grew from just 5.3% of the population in 1970 to around 31% by recent counts, with some researchers projecting that evangelicals could overtake Roman Catholics within a decade.

The evangelical upsurge has taken on a powerfully indigenous growth pattern, distinguishing it from older colonial missionary movements. It is organic, locally rooted, and adapts to the social pressures of each context. Pentecostalism in particular appears to thrive where dislocation, inequality, and political repression are most acute – offering direct religious experience, fluid authority structures, and a sense of individual agency to people who are otherwise disempowered.

This global picture directly challenged the secularization thesis. Berger argued that there is no reason to expect the twenty-first century to be any less religious than the world is today, and that those who neglect religion in their analyses of contemporary affairs do so at great peril.

Pluralism replaces secularism as the real challenge for religion 🔗

As Berger moved away from the secularization thesis, he did not simply declare religion’s victory. Instead, he proposed a more sophisticated lens: pluralism. Modernity, he concluded, does not necessarily produce secularity – it necessarily produces pluralism, meaning the coexistence within the same society of different worldviews and value systems. This, he argued, is the real transformation that modernity brings to religion – not the death of God, but the proliferation of competing gods, ideologies, and meaning systems.

Berger identified pluralism as operating on two levels: many religions and worldviews coexisting in the same society, and individuals experiencing a plurality of choices within their own consciousness. Both forms of pluralism destabilize what he called plausibility structures – the social frameworks that make a particular belief system feel self-evidently true. When a person lives surrounded by neighbors who believe differently, the taken-for-granted certainty of their own tradition erodes.

Berger saw religiosity and secularity as not mutually exclusive – we live in an age of pluralization where secular discourse has asserted itself globally without necessarily driving out religious belief. The two coexist, often within the same individual. This is a far more nuanced picture than the secularization thesis ever allowed.

The heretical imperative: faith as a personal choice 🔗

One of Berger’s most influential concepts flows directly from his theory of pluralism: the heretical imperative. In his 1979 book of the same name, Berger drew on the Greek root of the word “heresy” – hairein, meaning “to choose” – to argue that modernity had plunged religion into a crisis characterized above all by pluralism, forcing individuals to choose beliefs to which they had previously been assigned by birth and circumstance.

In many modern societies, religion has been pushed almost entirely into the private sphere, and religious commitment has become a highly personal choice – subject to revision as sociocultural and biographical circumstances change. Where a Tyrolean villager two centuries ago would have been Catholic as naturally as having a particular hair color, a person today must actively decide to affiliate, affirm, and maintain their faith in the presence of visible alternatives.

Berger saw this dynamic as particularly compatible with evangelical Christianity, whose core is precisely an act of personal decision – being “born again” requires a conscious, individual commitment rather than passive inheritance. In this sense, evangelical faith is not a throwback to premodern religion; it is structurally adapted to the demands of modern pluralism.

The individualization of religious belief does not mean belief weakens – it means it changes form. In Berger’s 2014 work The Many Altars of Modernity, he argued that pluralism reconfigures religious certainty into something more contingent and mutable – but this does not erase it. People still seek meaning, transcendence, and community. They simply navigate these needs differently in a pluralistic landscape.

Europe as the exception, not the rule 🔗

A recurring challenge to Berger’s revised position is the undeniable secularization of Western Europe. He addressed this directly rather than dismissing it. After co-authoring a study with British sociologist Grace Davie, Berger concluded that there were approximately eight distinct reasons why Europe differs from the rest of the world, with the most significant being the particular history of church-state relations on the continent. European secularization, he argued, is a specific regional outcome driven by institutional history – not a universal template for what modernity does to religion everywhere.

Some scholars like Pippa Norris and Ronald Inglehart do argue that virtually all advanced industrial societies have become more secular in recent decades, and Pew Research data shows that the religiously unaffiliated share of the global population grew slightly from 23.3% to 24.2% between 2010 and 2020. This tension is real, and Berger himself acknowledged it. He later clarified that his original framing of desecularization was “a bit sloppy,” and that the term is best understood as referring to religion’s resurgence in response to prior secularizing trends in specific contexts – not a claim that religion is universally flourishing everywhere at once.

Religion’s future: coexistence, not conquest 🔗

What Berger ultimately predicted for the future of religion was neither a triumphant return to premodern dominance nor a slow extinction. Instead, he envisioned a world where religion coexists with pluralism and modernity in a state of ongoing negotiation. Although modernization may have had some secularizing effects in some areas, it has also given rise to counter-secularization – old and new religious beliefs continue in the lives of individuals, while religiously identified institutions motivate people socially and politically even with limited formal membership.

Berger believed the resurgence of religion would shape four major areas in the coming century: international politics, war and peace, religion and economic development, and human rights and social justice. Each of these domains, he argued, can be influenced by religious vitality in ways that are neither uniformly positive nor negative – the outcomes depend on which religious movements are at play and how they engage with the modern order.

Recent Pew Research data confirms that religious populations continue to grow in absolute terms, with Muslims increasing by 347 million between 2010 and 2020, and Christians reaching 2.3 billion. Pentecostal and evangelical communities have expanded rapidly in Africa and Latin America, fueling renewed energy within these traditions, even as secularization continues to influence social attitudes in developed nations. The picture Berger painted – of a world simultaneously more religious and more pluralistic – appears to be precisely what is unfolding.

Berger’s final contribution was perhaps this: he insisted that the future of religion cannot be read off a single trend line. The sacred canopy that once sheltered entire civilizations has not simply dissolved – it has fragmented into many smaller, more personal, and more contested canopies, each sustained by individual choice within a pluralistic world. That fragmentation is itself a form of religious vitality, and it is one that the original secularization thesis was never equipped to see.

What do you think? If modernity produces pluralism rather than secularism, does that mean religious belief today is inherently more fragile – or does the act of consciously choosing a faith actually make it more resilient? And in a world where religion and pluralism coexist, how should secular institutions and policymakers engage with religious communities whose influence is clearly not fading?
