The interaction between Christianity and liberalism necessitates a precise and robust definition of the term “liberalism.” In its broadest sense, liberalism has been associated with various ideologies, from an open-minded approach to thought and theology to the embrace of contemporary trends. It is a fluid term, adapting to cultural, intellectual, and historical conditions, which often leads to what was once deemed “liberal” later being seen as conservative without a shift in foundational beliefs.
However, theological liberalism refers not merely to an intellectual disposition but to a specific historical and philosophical movement that emerged from the intellectual currents of the nineteenth century. It is deeply intertwined with the rationalist and naturalist ideals of the Enlightenment. Nineteenth-century theological liberalism arose as a response to modernism, particularly shaped by naturalism—a philosophical doctrine which asserts that all phenomena must be understood through natural explanations, rejecting any supernatural causality. This intellectual shift profoundly impacted Christian theology, leading to a systematic deconstruction of supernatural elements that had traditionally been central to Christian orthodoxy.
The Enlightenment’s Impact on Theological Liberalism
The theological liberalism of the nineteenth century can trace its intellectual roots to the Enlightenment, a period that elevated reason and empirical observation as the supreme arbiters of truth. The naturalistic philosophies of figures such as David Hume and Immanuel Kant played a crucial role in challenging traditional Christian views of the supernatural. In the face of Enlightenment rationalism, the miraculous elements of Christianity—those elements that orthodox Christianity had long held as divine interventions—were subjected to rigorous critique. As the Enlightenment philosophers argued for a worldview that excluded the supernatural, nineteenth-century theologians sought to reconcile Christianity with these new intellectual demands.
A primary target of liberal theologians was the New Testament’s accounts of Jesus’ miracles. In their view, the miracles of Jesus, such as the feeding of the five thousand, were not historical events but mythological constructs designed to communicate moral or ethical lessons. The liberal interpretation, as exemplified in the work of theologians such as David Friedrich Strauss and Rudolf Bultmann, reduced these miracles to either clever deceptions or allegories about ethical behavior. In this view, Jesus did not miraculously multiply loaves and fish, but rather inspired those in the crowd to share what they had. Such reinterpretations are emblematic of the broader liberal agenda of demythologizing Scripture, an intellectual endeavor that sought to strip the Bible of its supernatural elements to make it compatible with modern scientific thought.
The Rejection of Supernatural Christology
This demythologizing trend extended beyond the miracles of Jesus to the core doctrines of Christology. Liberal theologians systematically deconstructed the supernatural claims central to Christian belief: the virgin birth, the atonement, the resurrection, the ascension, and the second coming of Christ. Each of these doctrines, which had been traditionally understood as supernatural events, was recast in naturalistic or mythological terms. The virgin birth, for instance, was often dismissed as a later addition by early Christians, a mythological narrative borrowed from other ancient traditions to lend divine significance to Jesus’ life. The resurrection, likewise, was not seen as a historical event in which Jesus physically rose from the dead, but rather as a symbolic expression of the disciples’ belief in the continued relevance of Jesus’ teachings.
This rejection of the supernatural extended to the authority of Scripture itself. Liberal theologians denied the Bible’s divine inspiration, viewing it instead as a purely human document subject to historical and literary criticism. Predictive prophecy was similarly dismissed as an invention of later editors, and the Bible’s accounts of miracles were regarded as products of a pre-scientific worldview. This methodological shift led to a rejection of the Bible as the authoritative source of Christian doctrine. As a result, theological liberalism not only undermined the supernatural elements of Christianity but also eroded the very foundation of Christian doctrinal development. Doctrine, traditionally understood as the church’s interpretation of divine revelation in Scripture, was now regarded as a secondary concern, subordinate to the demands of contemporary intellectual trends.
The Social Gospel: Redefining the Church’s Mission
One of the most significant consequences of theological liberalism was the emergence of the social gospel movement, a redefinition of the church’s mission that focused on social rather than personal redemption. As liberal theology gained influence within both European and American theological circles, many clergy who no longer adhered to orthodox doctrines faced a dilemma: should they resign from ministry, or should they redefine the church’s mission to align with their new theological views? Most chose the latter course, leading to a fundamental shift in the church’s understanding of the Gospel.
The social gospel emphasized the church’s role in addressing societal ills, such as poverty, injustice, and inequality. While it made significant contributions to social reform, it did so at the expense of traditional Christian doctrines, particularly those concerning sin, salvation, and the need for personal redemption through Christ. In the liberal theological framework, the Gospel was no longer about the supernatural redemption of individuals but about the moral uplift of society through humanitarian action. This redefinition of the Gospel mirrored broader societal trends, particularly in the industrializing Western world, where the church’s influence on social ethics was increasingly seen as its primary role.
The Contemporary Legacy of Theological Liberalism
The theological liberalism of the nineteenth century has left an indelible mark on contemporary Christianity. In many mainline Protestant denominations, liberal theology has become the dominant paradigm, resulting in the significant erosion of biblical authority and doctrinal orthodoxy. Recent sociological studies indicate that denominations embracing liberal theology have experienced a marked decline in membership. For instance, research from the Pew Research Center notes that mainline Protestant denominations in the United States have been steadily shrinking, while evangelical churches—many of which maintain a high view of biblical authority—have shown greater resilience, albeit with slower growth rates in recent years. These findings suggest that the weakening of doctrinal clarity and biblical authority correlates with a declining public presence of Christianity, particularly in Western cultures that are increasingly secularized.
Statistical analyses also suggest that the decline of mainline Protestantism has broader implications for the role of Christianity in public life. As Christianity becomes more marginalized in secular societies, the church’s ability to offer a coherent alternative to moral and cultural relativism is diminished. In this context, the liberal theological agenda, which continues to assert its influence in both mainline and evangelical churches, represents a direct challenge to the historic Christian faith. Far from being a benign theological alternative, liberalism constitutes a rejection of the foundational claims of Christianity, particularly the divinity of Christ, the authority of Scripture, and the necessity of personal redemption.
The Implications of Scientific Discoveries on Theological Liberalism
Recent scientific discoveries, particularly those made through the James Webb Space Telescope (JWST), have further influenced contemporary theological discussions. The JWST’s unprecedented capacity to explore distant galaxies and uncover new dimensions of cosmic history has deepened the dialogue between science and theology. Liberal theologians have often cited scientific advancements as reasons for revising traditional doctrines, particularly those involving the supernatural. However, as discoveries like those from JWST expand our understanding of the universe’s complexity, they also invite renewed reflection on the theological significance of creation, divine action, and the nature of God’s interaction with the cosmos. Far from negating the supernatural, these discoveries can provide a more profound context for understanding the majesty and transcendence of God, challenging the reductionist tendencies of theological liberalism.
Conclusion
Theological liberalism, emerging from the intellectual currents of the Enlightenment and solidified in the nineteenth century, continues to exert a profound influence on contemporary Christianity. Its rejection of the supernatural, deconstruction of biblical authority, and emphasis on social rather than personal redemption have reshaped the mission and message of many churches. However, this liberal agenda represents a wholesale rejection of core Christian doctrines and poses a direct challenge to the historic faith of the church. As new scientific discoveries, such as those from the James Webb Space Telescope, expand our understanding of the universe, they also invite a reexamination of theological liberalism’s claims. The church must remain vigilant in defending the historic Gospel of Jesus Christ, ensuring that its mission and message remain rooted in the unchanging truths of Scripture while engaging thoughtfully with the insights of modern science.
