The discourse on truth remains central to theological and philosophical inquiry, particularly as postmodernism presents a fundamental challenge to the classical conceptions of truth as objective and universal. In the Christian tradition, truth has been inseparable from the divine, with theological assertions positioning God as the ultimate source and guarantor of all truth. However, the postmodern turn, driven by intellectual figures like Jacques Derrida and Michel Foucault, destabilizes these long-held assumptions, advocating for a more fragmented, contingent view of truth. This essay examines the postmodern deconstruction of truth, critiques its impact on both secular and theological discourse, and explores its implications for Christian theology, particularly in light of recent scientific developments revealed by the James Webb Space Telescope (JWST).
Theological Foundations of Truth and the Enlightenment Shift
Historically, Christian theology has articulated truth as an ontological attribute of God, inextricably linked to divine revelation. This conviction is epitomized in the declaration of Christ: “I am the way, the truth, and the life” (John 14:6). Theologically, truth is seen as a reflection of God’s unchanging nature, making it absolute, objective, and universal. Divine revelation, through both Scripture and the person of Christ, is the epistemological means by which humanity accesses this transcendent truth. Augustine’s Confessions echoes this sentiment, describing truth as that which eternally exists in the mind of God, accessible through faith and divine illumination.¹
However, the Enlightenment dramatically reoriented the locus of truth from divine revelation to human reason. Philosophers like Descartes, Locke, and Kant emphasized empirical observation and rational deduction as the new sources of knowledge. In this framework, truth became increasingly associated with the discoveries of science, governed by reason and experimentation rather than theological dogma.² The scientific revolution, fueled by thinkers such as Galileo and Newton, further solidified the empirical method as the primary means of accessing universal truths about the natural world, sidelining theology in the intellectual landscape of the West.
Yet, this modernist optimism about the attainability of universal truth through reason and science came under scrutiny in the latter half of the 20th century. The perceived failures of modernity, such as the destructiveness of industrialization, colonialism, and world wars, led to widespread disillusionment, setting the stage for the rise of postmodern philosophy.
Postmodern Epistemology and the Fragmentation of Truth
Postmodernism, particularly through the work of Derrida, introduces a radical critique of the Enlightenment’s assumptions regarding objective truth. Derrida’s Of Grammatology advances the theory of deconstruction, arguing that language itself is unstable, and thus the meaning and truth it seeks to convey are inherently fluid.³ Derrida contends that meaning is endlessly deferred, a process he calls différance, whereby no definitive interpretation or objective truth can be fixed. From this perspective, truth is not discovered but constructed through language and social interaction, making all truth claims contingent and relative.
Foucault extends this critique into the realm of social power, arguing that truth is a construct used by those in power to maintain control over societal norms and institutions.⁴ According to Foucault, truth is not a neutral or universal entity but is produced within discourses that reflect specific historical and cultural contexts. Thus, what is accepted as “truth” in any society is always intertwined with power relations, further eroding the possibility of an objective, universal truth.
This relativism presents a significant challenge to theological claims that are premised on the universality of Christian truth. Christian doctrine asserts that truth is not constructed but revealed by God, making it absolute and accessible to all people across time and space. As Paul writes in Romans 1:20, the truth about God is “clearly perceived” in the created world, leaving humanity “without excuse.” The postmodern rejection of metanarratives, however, destabilizes this claim, reducing even the gospel to a cultural construct rather than an ontological reality.
The Death of the Metanarrative and the Christian Response
Jean-François Lyotard’s The Postmodern Condition famously characterized postmodernism as “incredulity toward metanarratives.“⁵ This rejection of overarching, universal narratives—whether religious, scientific, or political—has profound implications for Christianity, which presents itself as a comprehensive metanarrative that spans from creation to eschaton. The Christian story of redemption, encompassing creation, fall, redemption, and restoration, is framed as the ultimate truth that explains the human condition and God’s interaction with the world. Alister McGrath, in his The Science of God, contends that this metanarrative provides coherence to the individual believer’s experience by situating personal salvation within the broader cosmic order.⁶
Postmodernism’s skepticism toward metanarratives, however, undermines Christianity’s claim to provide a universal, objective account of reality. Instead, postmodernism promotes localized, context-specific “little stories,” which challenge any singular interpretation of truth. This fragmentation threatens to relegate Christian theology to one narrative among many, weakening its claim to universality.
The James Webb Space Telescope and Cosmological Truths
Recent discoveries from the James Webb Space Telescope (JWST) provide a fascinating parallel to this epistemological tension between modernist and postmodernist frameworks. The JWST’s exploration of the cosmos has unveiled new information about the origins of galaxies, exoplanets, and star formations, expanding the boundaries of human knowledge about the universe. These scientific findings, rooted in empirical observation and advanced technology, embody the Enlightenment ideal of truth as discoverable through reason and investigation.
Yet, the vastness and complexity of the universe revealed by the JWST challenge human comprehension, reminding us of the limits of empirical knowledge.⁷ As theologians such as John Polkinghorne have argued, the sheer scale and mystery of the cosmos invite a theological response that transcends empirical data, pointing to the divine Creator who not only sustains the physical universe but also imbues it with meaning and purpose. In this way, the discoveries of the James Webb Space Telescope not only expand scientific understanding but also reaffirm theological claims about the contingency and dependence of creation upon God.⁸
Theological epistemology must, therefore, engage critically with both the scientific revelations of modernity and the philosophical critiques of postmodernity. While empirical science, as exemplified by the JWST, contributes significantly to our knowledge of the material universe, it remains insufficient to address questions of ultimate meaning and purpose, which lie beyond the purview of empirical methods. Theologians like Polkinghorne and David Bentley Hart emphasize the necessity of a metaphysical framework that encompasses both scientific truth and the deeper, metaphysical truths revealed by divine revelation.⁹
Reconciling Truth in a Postmodern World: A Theological Imperative
Given postmodernism’s pervasive influence and its challenge to the very notion of universal truth, how can Christian theology respond while maintaining its commitment to objective, revealed truth? One possible approach is to distinguish between different kinds of truth—scientific, historical, and theological—each with its own epistemological criteria, while simultaneously affirming their interconnectedness within the broader framework of God’s providential ordering of the world. This approach, rooted in the work of theologians like Thomas F. Torrance, recognizes that while scientific truths are provisional and subject to revision, theological truths are grounded in the eternal reality of God.¹⁰
Another critical response lies in reaffirming the role of divine revelation as the ultimate source of truth, while acknowledging the limitations of human understanding. As the JWST continues to reveal new complexities about the universe, Christian theology must resist the temptation to reduce truth to mere empirical data or subjective narratives. Instead, it should emphasize the coherence of theological truths with the empirical discoveries of science, while maintaining that the fullness of truth is ultimately revealed in the person of Christ, who reconciles the physical and metaphysical dimensions of reality.
Conclusion: Truth and the Horizon of Faith
The deconstruction of truth in postmodern philosophy poses a significant challenge to both secular and theological understandings of reality. By destabilizing traditional notions of objective and universal truth, postmodernism calls into question not only scientific and philosophical paradigms but also theological claims regarding divine revelation. However, recent advancements in cosmology, particularly through the discoveries of the James Webb Space Telescope, provide a timely reminder of the enduring quest for truth, which remains a central concern for both science and theology.
Christian theology, while engaging critically with postmodern epistemology, must hold fast to its conviction that truth is ultimately found in God. The task of theology is not to retreat into relativism or subjectivism but to witness to the transcendent truth revealed in Scripture and embodied in Christ. In doing so, theology reaffirms the coherence of God’s truth in a fragmented, postmodern world, offering a robust account of truth that encompasses both the empirical realities uncovered by science and the eternal verities revealed by faith.
