One often hears that Christianity is in decline due to the secularization of formerly Christian societies. However, secularization is best understood as a shared explanation for the decline of religion in general, not as a sufficient explanation for the decline of Christianity in particular. The same forces of modernity and secularization have affected other faiths as well, and yet Christianity’s decline is especially pronounced in Europe and North America. This suggests that something additional is occurring—something to which other religions appear more resilient.
I believe that theology is the core reason. In Christianity, religious identity is largely grounded in assent to specific metaphysical beliefs and far less in ritual practice. Rituals certainly exist: Christianity has sacraments, liturgical calendars, and communal practices. However, these are not constitutive requirements for Christian identity in the way belief is. One need not participate in ritual to remain a Christian, provided one affirms core metaphysical claims such as the virgin birth, the miracles of Christ, and the resurrection.
In Islam and Hinduism, by contrast, ritual plays a more central role. Islam combines strong doctrinal commitments with clearly prescribed ritual obligations that are widely understood as normative for Muslims. Hinduism contains philosophical schools that are highly metaphysical, but it also sustains a wide range of regional and communal ritual practices which, while not always strictly enforced, are commonly understood as duties of Hindu life. For individuals in the twenty-first century who hold a modern, scientific outlook, sustaining a religious identity grounded in ritual may be easier and more accommodating than sustaining one grounded primarily in metaphysical belief, which can feel epistemically strained under modern standards. Rituals operate in a different category: they do not compete with science in the way metaphysical truth claims do.
This emphasis on belief over ritual is not merely historical accident but is arguably inherent to Christianity itself. Jesus consistently subordinated ritual observance to moral intent and inner transformation. His disputes with the Pharisees over Sabbath laws and ritual purity illustrate this orientation. He emphasized universal virtues such as love, forgiveness, mercy, and justice over strict adherence to external practices. Christianity was therefore predisposed from its origins to prioritize interior belief and moral orientation over ritual.
As a result, one can be a Christian without performing any ritual at all, simply by affirming Christianity’s metaphysical claims. Ironically, even adherence to Christianity’s demanding moral ethics becomes socially optional. A person is not typically identified as Christian for being generous, forgiving, or merciful; such traits merely qualify one as a ``good person.'' Conversely, a morally ambiguous individual who affirms the virgin birth, the miracles of Christ, and the resurrection is readily identified as Christian, especially if this belief is expressed through visible symbols.
Religions can be understood as comprising three dimensions: a moral system, a metaphysical framework, and ritual practices. Each contributes differently to an individual’s sense of attachment to a religious tradition. Metaphysics and ritual appear to carry the greatest weight in anchoring religious identity, while morality carries the least, as moral principles often overlap across religions and secular philosophies.
Historically, in many faiths—including Christianity—these three dimensions were tightly coupled. In Christianity, however, ritual gradually became less central, particularly after the Protestant Reformation. In other religions, when metaphysical claims were challenged by modernity, ritual and moral practice often remained bound together and continued to sustain religious identity. When Christian metaphysics came under sustained pressure from modernity—and given Christianity’s comparatively weak ritual anchoring—what largely survived was morality alone. Morality by itself, however, provides the weakest foundation for religious identity.
In other words, Christianity as it is socially recognized ties identity primarily to metaphysical belief; modernity undermines metaphysical belief; Christian rituals are insufficiently binding to compensate; morality alone survives, but morality cannot anchor identity.
From a modern perspective, there is therefore no distinctly surviving Christian culture in much of the secularized West, though robust Christian cultures persist within Catholicism and Eastern Orthodoxy. One could argue that Western culture itself—especially in places such as Germany and the Nordic countries—is the unnamed surviving Christian culture, having disassociated itself from Christianity as a named religion. Western civilization’s ethics, values, modes of reasoning shaped by Christian natural theology, and moral intuitions—together constituting what we call modernity—are deeply Christian in origin, particularly through Protestant influences in England and Germany and Catholic influences during the Renaissance. This does not imply that modern science, technology, or morality are identical to Christianity in a dogmatic sense, nor that those who participate in modernity have unwittingly become Christian. Rather, it traces the historical development of modernity through a cultural ecosystem shaped by Christianity.
The intellectual and institutional yields of modernity that emerged from this Christian cultural ecosystem gradually separated themselves from religion as such. In the process, religious culture itself was clarified into two components: social, cultural, and moral practices on the one hand, and religious symbols and metaphysical claims on the other. Only the former survived and continues to coexist comfortably with a modern outlook. This was not a simple matter of extracting ethics directly from scripture. Rather, philosophers and intellectuals who were educated within this Christian cultural environment increasingly reasoned independently, arriving at moral frameworks that often coincided with Christian ethics. Importantly, these moral conclusions also converge with those found in Islamic, Hindu, Buddhist, and secular traditions, suggesting that they emerge as much from reflection on human nature and social life as from any particular religious doctrine.
Today, many—particularly in conservative circles—fear that immigration may erode ``Christian ethics.'' From this perspective, such fears appear misplaced. Christian culture is not fragile, because Western culture itself, now global in scope, is a secularized form of Christian culture. It is Christian not by virtue of metaphysical commitment, but by virtue of its historical development within an ecosystem infused with Christian ethics and embedded in Christian institutional structures, including the church--state alliances characteristic of many Enlightenment-era European societies. Even figures such as Isaac Newton lived within this framework; at Cambridge, scholars were required to take vows of celibacy in preparation for religious service, though Newton himself ultimately declined ordination, likely due to his heterodox theological views.
This cultural inheritance underlies modern science, moral frameworks, social organization, and political institutions. These worldviews demonstrably function, and much of the world benefits from them. Societies do not abandon frameworks that deliver tangible benefits.
None of this implies marginalizing other faiths. Secularized forms of many religions increasingly converge on similar modern frameworks. The ethics of reciprocity underlying many contemporary moral norms are not exclusive to Christianity, even when they were historically influenced by it.
The deeper concern expressed by many conservatives, if there is one, is not the preservation of moral systems, social organization, economics, or science, but the problem of meaning and purpose. For adherents of many faiths, meaning is sustained through ritual and ethno-religious cohesion that can coexist with modernity. For many Westerners, however—those who embrace modernity without inherited metaphysical structures—meaning is more fragile. The unspoken anxiety is that humans inevitably seek meaning, and that in the absence of their own symbolic and ritual anchors, Western societies may eventually turn elsewhere not for moral systems, but for existential grounding.
The current condition of the West, and perhaps its central problem, is the presence of an existential vacuum once filled by Christian metaphysics. Many do not know how to address this vacuum, or prefer not to confront it directly, and instead displace their anxiety onto new waves of people from other regions, framing them as a threat. While adherents of other faiths often inhabit modernity alongside robust meaning-making systems rooted in ritual and communal identity, the modern Westerner frequently stands alone before an indifferent cosmos—fully equipped with modern knowledge, yet sustained by fragile and improvised sources of meaning.
