The struggle for a soul in a test tube, where scripture met science.
The Netherlands, one of the world's most secular nations, holds a surprising secret: it is a historic stronghold of creationism. For much of the twentieth century, a fierce intellectual battle raged not in the public squares but within the heart of its orthodox Protestant community.
A highly secular country with a deep history of creationist thought.
One of few countries outside the U.S. with entrenched creationism.
The conflict pitted deep-rooted Calvinist faith against the growing evidence for Darwinian evolution, transforming the Netherlands into one of the few countries outside the United States where creationism became deeply entrenched. This is the story of how a religious tradition, founded on engaging with modern thought, grappled with a revolutionary scientific idea that threatened to upend its worldview. From cautious curiosity to fierce rejection and, finally, to a hard-won dialogue, the journey of Dutch Calvinists between 1900 and 1960 reveals a profound struggle to reconcile the Book of Scripture with the Book of Nature.
As the 19th century ended, Dutch Calvinism was reshaped by two towering intellectuals: Abraham Kuyper (1837-1920) and Herman Bavinck (1854-1921). They founded the neo-Calvinist movement, an attempt to revitalize orthodox Calvinism for the modern era 3 .

1854-1921
Theologian who shaped neo-Calvinist engagement with science
Their core principle was "Sphere Sovereignty"—the idea that different areas of life, such as church, state, and science, possess their own God-given authority and integrity 5 .
"They rejected the 'warfare thesis' that pitted religion against science 3 . Instead, they championed a distinctively Christian science, free from materialist dogma, that could genuinely explore God's creation."
In 1880, Kuyper founded the Free University of Amsterdam (VU) to cultivate this "science with the heart" 5 .
Founded in 1880 by Abraham Kuyper to promote a distinctively Christian approach to science and scholarship.
Their view of evolution was ambivalent. While deeply critical of Darwinism's perceived mechanistic materialism, which seemed to leave no room for divine providence, they were not strict biblical literalists 5 . Bavinck, influenced by geological evidence, acknowledged the Earth's vast age and allowed for God using gradual processes 5 . This relative openness, however, was not to last.
The second generation of neo-Calvinist theologians, fearing assimilation into secular culture, began to enforce stricter doctrinal boundaries 5 . Figures like Valentijn Hepp pushed for a more literal interpretation of Genesis, including a recent creation and a global flood 5 .
Theological hardening begins as second-generation neo-Calvinists enforce stricter boundaries.
George McCready Price publishes "The New Geology" promoting flood geology.
The Geelkerken Case results in suspension of a pastor for questioning literal interpretation of Adam and Eve.
Young-Earth creationism becomes part of neo-Calvinist orthodoxy in the Netherlands.
This theological hardening required a "scientific" justification, which they found in an unlikely source: American fundamentalism.
This shift culminated in the Geelkerken Case of 1926, a defining moment for Dutch Calvinism 3 5 . Rev. J.G. Geelkerken was suspended by the Synod of the Reformed Churches for publicly questioning whether the story of Adam and Eve should be interpreted with strict historical literality. This event, dubbed the Dutch "Monkey Trial," signaled a victory for the conservative, literalist faction and created a chilling effect. Scientists and theologians expressing openness to evolution faced marginalization, cementing young-Earth creationism as part of the neo-Calvinist orthodoxy by the 1930s 3 .
The post-World War II era saw a new generation of Calvinist scientists who were less bound by the interwar battles. Foremost among them was Dr. Jan Lever (1922-2010), appointed Professor of Zoology at the Free University in 1952 5 .
1922-2010
Professor of Zoology at the Free University whose research on crustacean regeneration challenged creationist dogma.
His research on limb regeneration in crustaceans became a pivotal scientific and theological challenge to creationist dogma. Lever's work focused on a deceptively simple question: Could the mechanisms governing the regeneration of lost limbs in creatures like crayfish shed light on fundamental questions of development, inheritance, and, ultimately, the plausibility of evolutionary change?
Lever's research was a model of meticulous, empirical science 5 :
Lever's research provided a detailed empirical map of crustacean regeneration. His key findings pointed overwhelmingly toward common descent 5 :
| Stage | Duration (Approx.) | Key Cellular/Tissue Events | Observable Morphology |
|---|---|---|---|
| 1. Wound Healing | Hours - 2 days | Epidermis migrates over wound; clot formation | Wound sealed |
| 2. Blastema Formation | 2 - 7 days | Dedifferentiation of tissues; accumulation of mesenchymal cells | Small, rounded bud appears |
| 3. Differentiation | 1 - 3 weeks | Blastema cells differentiate into precursors for cuticle, muscle, nerve | Bud elongates; segmentation becomes visible |
| 4. Growth & Patterning | Several weeks - Months | Rapid cell proliferation; precise patterning of new structures | Limb approaches pre-amputation size and form |
| 5. Functional Integration | Post-molt | New cuticle hardens; neural and muscular connections integrate | Functional limb restored |
| Observation | Implication for Common Descent |
|---|---|
| Conserved Stages: Similar sequence of regeneration across diverse crustaceans | Suggests a shared, inherited developmental program, not independent designs |
| Homologous Genetic Pathways: Activation of similar genetic toolkits in different species | Indicates these regulatory genes were present in a common ancestor |
| Developmental Plasticity: Ability to reactivate embryonic-like states in adult tissues | Demonstrates the inherent capacity for significant morphological change within genomes |
| Nerve Dependence: Similar requirement for nerve-derived factors in crustaceans and salamanders | Suggests deep evolutionary roots for this regulatory mechanism |
In 1956, Lever synthesized his scientific and theological reflections in his groundbreaking and controversial book, "Creation and Evolution" (Schepping en Evolutie) 5 . He argued that the biological evidence for evolution was overwhelming and could not be dismissed by "flood geology."
Lever's seminal work that argued for compatibility between evolutionary theory and Christian faith, creating a seismic shift in Dutch Calvinist thought.
Crucially, he contended that accepting evolution was compatible with a robust Christian faith in a Creator God who works through natural laws.
"The impact was seismic. Lever's work initiated a fierce public debate about creation and evolution among Dutch Calvinists 3 ."
While many non-academic Calvinists were outraged, a younger generation of scientists and theologians saw his work as a liberation. It provided a credible path to engage with modern biology without abandoning their faith. By the 1960s, his views were gradually gaining acceptance, leading the main Reformed Churches and the Free University to become more open to evolutionary theory—a transformation that, in turn, caused more conservative factions to break away and uphold strict creationism 3 .
The period from 1900 to 1960 marked a profound transformation for Dutch Calvinism. It began with the foundational, albeit cautious, engagement of Kuyper and Bavinck, moved through a period of rigid, imported creationism, and was finally challenged from within by the rigorous science of Jan Lever.

Lever's empirical research reopening the dialogue
Lever's research on regeneration did more than just explain how a crayfish regrows a claw; it provided a powerful, empirical argument for common descent that could not be easily ignored by his community.
"This struggle was never just about science. It was about cultural identity, biblical interpretation, and authority within a tight-knit religious community navigating the pressures of the modern world 2 3 ."
The eventual, albeit partial, acceptance of evolution by the mainstream Calvinist institutions in the Netherlands by the 1960s did not end the debate. Instead, it set the stage for the next phase of a complex dialogue between faith and science—a dialogue that continues to this day, reminding us that the integration of deep-seated belief with scientific discovery is rarely a simple revolution, but more often a slow and arduous evolution.
