The advent of postmodernism, with its repudiation of meta-narratives and skepticism towards claims of absolute truth, has fundamentally altered the landscape of Christian theology and apologetics. This philosophical framework engenders a relativistic approach to truth, destabilizing the epistemic foundations upon which traditional Christian orthodoxy rests. At the heart of this challenge lies the incompatibility between Christianity’s claim of objective, divine revelation and the postmodern assertion that truth is culturally contingent and individually constructed. The tension becomes particularly acute in a world increasingly shaped by scientific discovery, particularly cosmological findings from groundbreaking technologies like the James Webb Space Telescope (JWST). In response to these developments, this essay will examine the theological implications of epistemic pluralism and scientific discovery, arguing for a robust, coherent Christian apologetic that affirms the uniqueness of Christ and the objective reality of divine truth. In doing so, we will engage with contemporary philosophical and scientific insights while maintaining fidelity to traditional Christian doctrine.
Theological Foundations and the Crisis of Truth in Postmodernity
Christian theology has long been grounded in the conviction that God’s revelation in Jesus Christ is both universal and exclusive. This is encapsulated in Christ’s affirmation in John 14:6: “I am the way and the truth and the life. No one comes to the Father except through me” (NIV). Such a claim presupposes the existence of objective truth—a truth that transcends subjective human experience and stands in direct opposition to the epistemic relativism of postmodern thought. Postmodernism, heavily influenced by thinkers like Michel Foucault and Jacques Derrida, denies the possibility of a singular, overarching truth, instead promoting a multiplicity of perspectives that are seen as equally valid. This intellectual framework profoundly challenges the core tenet of Christian particularism: the assertion that Christ alone is the definitive revelation of God.
The implications of this relativistic framework are not merely theoretical; they bear directly on the church’s engagement with broader cultural and intellectual currents. As theologian Stanley Grenz points out, “Postmodernism relativizes all truth claims, including theological ones, by relegating them to the realm of the merely ‘local’ or ‘contextual.’”1 This shift has given rise to a pluralistic theology that embraces religious diversity as normative and disavows any claim to religious exclusivity. From this vantage point, Christianity’s insistence on the unique lordship of Christ appears intolerant or anachronistic, a relic of a bygone era of meta-narratives.
However, as John Milbank argues in Theology and Social Theory, postmodernism’s critique of objective truth does not negate the possibility of coherent theological discourse. Rather, it compels Christian theologians to reframe their epistemological foundations. Milbank asserts that theology must maintain its own narrative, unapologetically rooted in the belief in a revealed, transcendent order. This perspective challenges the postmodern reduction of all knowledge to human social constructs and insists that divine revelation operates beyond human subjectivity.2
The Law of Non-Contradiction: Theological Rigor in an Age of Relativism
A crucial apologetic strategy in responding to the postmodern challenge is the reaffirmation of the law of non-contradiction - namely, that something cannot be both true and false at the same time and in the same respect. This logical principle is as applicable to theological claims as it is to scientific or philosophical ones. If Christianity proclaims that Jesus Christ is the incarnate God, then religious systems that deny His divinity, such as Islam, must be considered theologically erroneous. This assertion is not an act of intolerance but rather an expression of intellectual integrity and theological consistency.
Kenneth Richard Samples articulates this point when he writes, “Jesus Christ cannot be both God incarnate (as Christianity asserts) and not-God incarnate (as other religious systems claim) at the same time.”3 In other words, to affirm theological relativism is to undermine the very possibility of coherent truth claims, reducing theology to mere preference or cultural artifact. To preserve the intellectual and doctrinal integrity of Christian theology, apologists must resist the temptation to accommodate relativistic notions of truth that would render Christ’s unique identity negotiable.
Cosmology and Theological Reflection: The Contributions of the James Webb Space Telescope
The scientific discoveries emerging from the James Webb Space Telescope (JWST) provide profound opportunities for theological reflection, particularly concerning the doctrine of creation. The JWST, which launched in 2021, has offered unprecedented views of the universe’s early galaxies, stellar nurseries, and complex cosmic structures, expanding our understanding of the universe’s vastness and intricacy. These findings invite Christians to contemplate the majesty of God’s creative work in light of modern cosmology.
Psalm 19:1 declares, “The heavens declare the glory of God; the skies proclaim the work of his hands” (NIV), a truth that the JWST’s observations of distant galaxies and cosmic phenomena vividly illustrate. The JWST’s exploration of the universe’s fine-tuned complexity - revealed through the delicate balance of physical constants and laws - reaffirms the theological claim that creation reflects the rationality and orderliness of its Creator. As noted by Alister McGrath, “The intelligibility of the cosmos is one of the most significant features of the natural order, and it points unmistakably to a rational divine Creator.”4
The JWST’s findings further challenge the postmodern inclination to reduce religious belief to subjective experience or metaphorical expression. The universe’s intricate design, observable through the precision of cosmological constants, underscores the existence of an objective order that transcends human interpretation. This not only affirms the coherence of the doctrine of creation but also reinforces the apologetic claim that the God of Christianity is not a mere projection of human subjectivity but the transcendent ground of all being.
Christ’s Lordship in the Context of Pluralism: Theological Exclusivity and Inclusivity
In an age of increasing religious pluralism, the exclusive claims of Christianity are often viewed with suspicion or hostility. Theological relativism has sought to recast the Lordship of Christ as one truth among many, diluting the gospel’s distinctive message. Yet, as theologian Lesslie Newbigin argues in The Gospel in a Pluralist Society, the Christian proclamation of Christ’s Lordship transcends cultural and religious boundaries, offering a universal truth that cannot be relegated to the status of personal or cultural preference. “The Christian affirmation is that Jesus is not one of many revelations of God, but the definitive self-disclosure of God.”5
Newbigin’s critique of pluralism is particularly relevant in a postmodern context, where the tendency is to equate social inclusivity with theological relativism. While the church is called to respect and engage with individuals of other faiths, this respect must not come at the expense of theological truth. The assertion of Christ’s Lordship is, fundamentally, a declaration that the God revealed in Jesus Christ is not confined to any one culture or religious tradition but is the sovereign Creator and Redeemer of the entire cosmos.
Toward a Coherent Christian Apologetic
In conclusion, the challenges posed by postmodern relativism and scientific discovery demand a coherent and rigorous Christian apologetic. The findings of the James Webb Space Telescope, far from undermining Christian theology, offer profound insights into the grandeur and orderliness of God’s creation, reinforcing the objective truth of the gospel. By maintaining the law of non-contradiction, engaging with contemporary scientific discoveries, and affirming the unique Lordship of Christ, Christian theology can respond effectively to the relativistic tendencies of postmodernity. Ultimately, the Christian faith, rooted in the objective revelation of God in Christ, offers a compelling vision of truth that transcends the shifting cultural and intellectual currents of the present age.
