For much of the twentieth century, religious history was written from the top down. Ecclesiastical historians traced the development of church institutions, theologians reconstructed doctrinal disputes, and denominational scholars chronicled the lives of bishops, reformers, and synods. The archives dictated the story, and the archives belonged to the powerful.

But beginning in the 1970s, a quiet revolution reshaped the field. Historians began asking a different question: not what the church taught, but what ordinary believers actually did, felt, and believed. The pew mattered as much as the pulpit. Folk practices, domestic devotions, and heterodox improvisations became legitimate objects of inquiry.

This shift did not simply add new material to old narratives—it fundamentally challenged how historians conceptualized religion itself. Comparing the older institutional historiography with the newer histories of lived religion reveals two schools operating with incompatible assumptions about where religion resides, who counts as religious, and how change occurs across centuries.

The first significant break came from social historians influenced by the Annales school and British Marxist historiography. Scholars like Keith Thomas in Religion and the Decline of Magic and Carlo Ginzburg in The Cheese and the Worms demonstrated that the religious world of ordinary Europeans bore only a partial resemblance to official Christianity.

These historians uncovered persistent syncretisms: charms alongside prayers, saints functioning as local deities, calendar rituals absorbing pagan substrata. The elite-popular dichotomy became a productive analytical frame, though one that later scholars would complicate. What appeared as ignorance or superstition in older institutional histories was reinterpreted as a coherent, if unofficial, religious system.

This approach owed much to E.P. Thompson's insistence on rescuing the lower classes from the condescension of posterity. Yet it also drew from ethnographic anthropology, particularly the work of Clifford Geertz on religion as a cultural system. The methodological toolkit expanded to include inquisitorial records, wills, folklore collections, and material culture.

The limitation of this first wave was its tendency to treat popular religion as a stable substrate resisting elite imposition—a binary that flattened the constant exchange between clerical and lay religious worlds. Subsequent scholarship would dissolve this opposition without abandoning the analytical gains it had produced.

Takeaway

When historians change the question from what institutions taught to what people practiced, the shape of the past itself changes. Sources previously dismissed as marginal become central evidence.

By the 1990s, the popular-elite framework itself came under critique. Robert Orsi, David Hall, and their collaborators developed what they called the lived religion approach, drawing inspiration from French sociologist Michel de Certeau's analysis of everyday practice. The point was no longer to contrast popular deviation with orthodox norm, but to examine religion as something practiced by everyone, everywhere, in embodied and material forms.

Lived religion methodology attends to what people do with religious ideas in kitchens, on subway cars, at deathbeds, and in traffic. It refuses the separation between belief and practice that had structured earlier scholarship, treating theology itself as a form of practice and everyday gestures as forms of theological reasoning.

This framework proved particularly generative for the study of American religion, immigrant Catholicism, and Pentecostalism, where formal institutional structures often mattered less than affective communities and improvised rituals. Orsi's work on Italian Harlem and the cult of Saint Jude demonstrated how devotion functioned as a way of navigating suffering, gender, and diaspora simultaneously.

Critics have questioned whether the approach risks losing sight of institutional power and theological content altogether—whether the shift from doctrine to practice sometimes reproduces older Protestant assumptions that inner experience is the real seat of religion. The most sophisticated practitioners now work to hold institution and practice in productive tension.

Takeaway

Religion is not primarily what people believe but what they do—and the doing is inseparable from bodies, objects, and the mundane textures of daily existence.

The transformation in religious history has profoundly reshaped debates over secularization. The older sociological consensus—associated with figures like Peter Berger in his early work—held that modernization inevitably produced religious decline. Institutional histories tended to confirm this narrative by tracking falling church attendance, declining clerical authority, and the retreat of religion from public institutions.

But historians attentive to lived religion have painted a more complicated picture. Callum Brown's The Death of Christian Britain argued that religious decline in the West was not a slow linear process but a sudden gendered rupture in the 1960s. Hugh McLeod, José Casanova, and Charles Taylor each in different ways challenged the assumption that secularization named a single, coherent phenomenon.

Meanwhile, scholars of global religion pointed out that the classic secularization thesis was largely a description of Northwestern Europe generalized into a universal law. The vitality of religion in the Americas, Africa, and much of Asia demanded explanations that did not treat European trajectories as normative.

The result has been a more textured historiography: religion does not simply decline or persist but transforms, migrates, and reappears in unexpected forms. What looked like disenchantment from an institutional vantage point often looks like reconfiguration from the perspective of practice.

Takeaway

Grand narratives of decline often reflect where historians look rather than what is actually happening. Change is rarely linear, and disappearance from one domain frequently means emergence in another.

The turn from institutional to lived religion represents more than a shift in subject matter. It marks a broader methodological reorientation in which historians came to see religion less as a body of doctrine transmitted by institutions and more as an ongoing human practice negotiated in daily life.

Each school retains genuine strengths. Institutional historiography remains indispensable for understanding power, doctrine, and formal change. Lived religion illuminates the textures of belief that institutional records suppress. The most compelling recent work integrates both registers.

What emerges is a discipline more attentive to complexity, more skeptical of grand narratives, and more willing to sit with the strangeness of religious life across time.
