"Science and religion have always been at war." This claim is widely believed but historically false. The "warfare thesis"—the idea that science and Christianity are inherently opposed—is a nineteenth-century invention that serious historians have long abandoned. Understanding the real history of science and faith equips us to respond to one of the most common objections to Christianity and reveals that, far from being enemies, science and Christian faith have been fruitful partners.
The Warfare Thesis
The notion that science and religion are at war was popularized by two nineteenth-century books: John William Draper's History of the Conflict Between Religion and Science (1874) and Andrew Dickson White's A History of the Warfare of Science with Theology in Christendom (1896). These works portrayed history as a long struggle between enlightened science and obscurantist religion, with science gradually triumphing over superstition.
This narrative became deeply embedded in popular culture. It shapes how many people instinctively think about the relationship between faith and science. The conflict thesis appears in textbooks, documentaries, and countless popular articles. "Science vs. religion" is assumed to be a fundamental divide.
But the thesis is bad history. Contemporary historians of science, including secular scholars with no religious agenda, have thoroughly debunked it. The real history is far more complex, far more interesting, and far more favorable to the relationship between Christianity and science.
Historians on the Warfare Thesis
Historian David Lindberg writes: "There was no warfare between science and the church." Historian Ronald Numbers states: "The greatest myth in the history of science and religion holds that they have been in a state of constant conflict." Historian John Hedley Brooke notes: "Serious scholarship in the history of science has revealed so extraordinarily rich and complex a relationship between science and religion in the past that general theses are difficult to sustain." The experts agree: the warfare thesis is a myth.
The Real History
The actual relationship between Christianity and science has been predominantly one of support, cooperation, and mutual enrichment—not conflict.
Christianity and the Birth of Modern Science
Modern science emerged in Christian Europe, not despite Christianity but in significant part because of it. Several Christian beliefs created the intellectual conditions that made science possible:
Creation by a rational God: If the universe is created by a rational God, it will exhibit rational order that the human mind can discover. This expectation of cosmic rationality is foundational to scientific inquiry. Pagan worldviews, which saw nature as chaotic, arbitrary, or divine itself, provided no such expectation.
Nature as distinct from God: Christianity demystified nature. Unlike pantheism, which identifies nature with the divine, Christianity taught that nature is creation—distinct from God, not itself sacred. This made it legitimate to study, experiment on, and manipulate nature in ways that would be impious in a pantheistic worldview.
Humans made in God's image: If humans are made in the image of a rational God, human reason can be trusted to discover truth about God's creation. This confidence in human rationality undergirds the scientific enterprise.
The contingency of nature: Christian theology taught that God freely chose to create this particular world among many possibilities. This means we cannot deduce what nature is like from pure reason; we must observe it. This emphasis on empirical investigation is central to the scientific method.
"The heavens declare the glory of God; the skies proclaim the work of his hands."
— Psalm 19:1
Christian Scientists
The founders of modern science were overwhelmingly Christian—not nominally but devoutly. They saw their scientific work as studying God's creation and glorifying Him through understanding His works:
Nicolaus Copernicus (1473-1543): Catholic canon who developed the heliocentric model. He dedicated his work to the Pope and saw his astronomy as revealing God's design.
Johannes Kepler (1571-1630): Lutheran astronomer who discovered the laws of planetary motion. He described his work as "thinking God's thoughts after Him."
Galileo Galilei (1564-1642): Catholic scientist whose conflict with the church (more on this below) was not about science vs. religion but about biblical interpretation and ecclesiastical politics. Galileo remained a devout Catholic.
Robert Boyle (1627-1691): The father of modern chemistry, deeply devout, who funded lectures defending Christianity and studied Scripture in original languages.
Isaac Newton (1643-1727): Arguably the greatest scientist ever, Newton wrote more on theology than on science. He saw his physics as revealing God's mathematical design of the universe.
Michael Faraday (1791-1867): Pioneer of electromagnetism, a devout member of a small Christian denomination who saw nature as God's book.
James Clerk Maxwell (1831-1879): Formulated the equations of electromagnetism, a committed Presbyterian who prayed and studied Scripture daily.
The list could continue indefinitely. The history of science is filled with devout Christians who saw no conflict between their faith and their research.
Kepler's Motivation
Johannes Kepler, who discovered that planets move in ellipses, wrote: "The chief aim of all investigations of the external world should be to discover the rational order and harmony which has been imposed on it by God, and which He revealed to us in the language of mathematics." For Kepler, science was worship—a way of knowing and glorifying the Creator through His creation.
The Church's Support for Science
The institutional church has historically supported scientific inquiry:
Medieval universities: The first universities (Paris, Oxford, Cambridge, Bologna) were church institutions. They preserved ancient learning, developed logic and natural philosophy, and created the institutional framework within which science would later flourish.
Monastic scholarship: Monks preserved ancient texts through the "Dark Ages," copied manuscripts, and conducted early natural investigations. The medieval church was not the enemy of learning but its guardian.
Cathedral schools: Church-sponsored education included study of the natural world as part of understanding God's creation.
Patronage: The church funded scientific research, built observatories, and supported scientists. The Vatican Observatory, founded in 1891, continues this tradition today.
The notion that the church suppressed science is largely fantasy. The church occasionally censured individual scientists, but these cases were exceptions, not the rule—and often involved factors beyond science itself.
The "Conflict" Cases
What about the famous cases of conflict—Galileo, Copernicus, Darwin? Don't these prove the warfare thesis? Not when examined carefully.
Galileo
The Galileo affair (1616-1633) is the warfare thesis's poster child. But the reality is more complex:
The science was unsettled: In Galileo's time, the heliocentric model was not yet proven. Galileo couldn't explain stellar parallax (which would only be measured in 1838), and his theory of tides was wrong. Many scientists, not just churchmen, remained skeptical.
The conflict was partly personal: Galileo alienated former allies, including Pope Urban VIII, whom he seemed to ridicule in his Dialogue. His combative personality made enemies. The affair was as much about politics and personalities as about science.
The conflict was about biblical interpretation: The question was whether the Bible's language about the sun moving should be interpreted literally. This was a theological and hermeneutical question, not a science vs. religion battle. Galileo himself offered a sophisticated approach to reading Scripture that was later widely accepted.
The church's response was not typical: Galileo's condemnation was exceptional, not representative of how the church generally treated science. Many churchmen supported Galileo; he had defenders among the Jesuits; his works were widely read in Catholic countries.
Galileo himself never abandoned his faith. He remained a Catholic and was buried with Church honors. To make Galileo a martyr for science against religion distorts history.
Insight
The Galileo affair teaches important lessons—about the dangers of ecclesiastical overreach, the importance of distinguishing scientific from theological questions, and the need for humility about interpreting both Scripture and nature. But it does not teach that science and Christianity are at war. Even this worst-case scenario was a conflict within Christendom, not between Christianity and science.
Darwin and Evolution
The reception of Darwin's theory was more varied than often portrayed:
Religious scientists accepted evolution: Asa Gray, America's leading botanist and Darwin's correspondent, was a devout Christian who accepted evolution. Many Christian scientists in Darwin's time and since have embraced evolutionary theory while maintaining their faith.
Opposition was mixed: Some Christians opposed Darwin on scientific grounds (the theory had genuine problems that took decades to resolve). Some scientists opposed Darwin too. The divide was not simply religious vs. scientific.
Accommodation was common: Within a generation, most Christian thinkers had accommodated evolution in some form. The conflict that did exist was often about philosophical materialism (which Darwin's defenders sometimes promoted), not about the scientific mechanism itself.
The debates continue productively: Today, many Christians accept some form of evolutionary biology while others remain skeptical. These debates happen within the scientific and theological communities. Reasonable people disagree. This is normal scholarly discussion, not warfare.
The "Flat Earth" Myth
One of the warfare thesis's most persistent myths is that the medieval church taught the earth was flat and persecuted those who said otherwise. This is completely false.
The ancients knew the earth was round: Greek philosophers established the earth's sphericity centuries before Christ. This knowledge was never lost in the Christian West.
Medieval Christians knew the earth was round: Every educated person in the Middle Ages knew the earth was spherical. Dante's Divine Comedy, the most popular medieval work, presupposes a round earth. Columbus didn't face opposition because people thought the earth was flat; the dispute was over its circumference.
The myth was invented in the nineteenth century: Washington Irving's fictionalized account of Columbus (1828) and the warfare thesis authors perpetuated this myth. It has no basis in historical fact.
"It is he who sits above the circle of the earth, and its inhabitants are like grasshoppers."
— Isaiah 40:22
Why the Myth Persists
If the warfare thesis is bad history, why does it persist?
Rhetorical Usefulness
The conflict narrative serves certain agendas. For those who wish to discredit religion, portraying it as science's enemy is rhetorically powerful. For those who wish to promote a purely secular public sphere, casting religion as irrational and anti-progress is useful. The myth persists because it's useful, not because it's true.
Simplification
The real history is complicated. The warfare thesis is simple. In an age of soundbites and short attention spans, simple narratives win—even when they're false.
Genuine Conflicts
There have been genuine conflicts—specific instances where religious authorities resisted scientific claims. These real events get generalized into a universal narrative. But exceptions are not the rule; specific conflicts don't prove inherent warfare.
Confusion of Categories
Some conflicts are actually between science and specific theological interpretations, not between science and Christianity itself. Young-earth creationism's conflict with geology, for instance, is not Christianity vs. science but a particular interpretation of Genesis vs. mainstream science. Many Christians accept both their faith and the scientific consensus on earth's age.
The Nature of Conflict
When conflicts do occur, they're usually about the interpretation of evidence, the implications of theories, or the boundaries of authority—not about whether science or faith should exist. Scientists disagree with each other; theologians disagree with each other; sometimes scientists and theologians disagree. This is normal intellectual discourse, not warfare.
Science and Faith Today
How should Christians think about science and faith today?
Partners, Not Enemies
Science and Christianity are not inherently opposed. Both seek truth. Both use reason. Both make claims about reality. They address different questions—science asks "how"; theology asks "why"—but their answers should be consistent. God's revelation in nature and in Scripture come from the same source and cannot ultimately contradict.
Different Domains
Science investigates natural causes and mechanisms. Theology addresses meaning, purpose, and ultimate reality. These domains overlap in some areas (both make claims about human nature, for instance) but are largely complementary. Science tells us how the universe works; theology tells us why it exists and what it's for.
Humility Required
Both science and theology require humility. Scientific conclusions are provisional, subject to revision. Theological interpretations can be mistaken. When apparent conflicts arise, we should proceed carefully, recognizing that we might be wrong—about the science, about the theology, or about both.
Engagement, Not Retreat
Christians should engage with science, not retreat from it. We should pursue scientific vocations, participate in scientific research, and think carefully about the theological implications of scientific findings. The Christian tradition of natural theology—learning about God through nature—invites this engagement.
"For since the creation of the world God's invisible qualities—his eternal power and divine nature—have been clearly seen, being understood from what has been made."
— Romans 1:20
Responding to the Objection
When someone says "Science and religion are at war," how should you respond?
Question the Assumption
"What makes you think that? Can you give examples?" Often people have absorbed the narrative without examining it. Asking for specifics can reveal that their evidence is thin.
Share the Real History
"Actually, historians have largely abandoned the warfare thesis. Modern science emerged in Christian Europe, founded by devout Christians who saw their work as studying God's creation. The conflict narrative is nineteenth-century propaganda, not historical fact."
Acknowledge Real Tensions
"There have been tensions—the Galileo affair, debates over evolution. But these are exceptions, not the rule, and they're more complex than the simple 'science vs. religion' story suggests. Reasonable people disagree about difficult questions; that's not warfare."
Point to Christians in Science
"Today, many scientists are Christians—including leading researchers in physics, biology, chemistry, and medicine. Francis Collins, director of the NIH and leader of the Human Genome Project, is an outspoken Christian. If science and faith were at war, how would that be possible?"
A Conversation Approach
"I used to think science and religion were opposed, but then I actually looked into the history. It turns out the 'warfare' idea was invented in the 1870s by writers with an agenda. The real history is different. Copernicus was a church canon. Newton wrote more about theology than physics. The founders of modern science were devout believers who saw their work as exploring God's creation. There have been tensions, sure, but the overall story is one of cooperation, not conflict. Don't take my word for it—look up what historians of science actually say."
Conclusion: Allies in Truth
The warfare thesis is a myth—a useful myth for some, but a myth nonetheless. The real history of science and Christianity is a story of partnership, mutual support, and shared pursuit of truth. Modern science emerged from a Christian intellectual framework and was pioneered by Christian scientists who saw their work as glorifying God.
This doesn't mean there are never tensions. Hard questions arise where science and theology intersect. Christians disagree about how to interpret both Scripture and scientific findings. But these are family disputes, not civilizational warfare. They're the kind of disagreements that occur whenever thoughtful people grapple with difficult questions.
The Christian can approach science with confidence, not fear. The God who inspired Scripture also created the natural world. Truth cannot contradict truth. Where science reveals how the universe works, it reveals God's handiwork. Where theology reveals why the universe exists, it provides the meaning science alone cannot supply. Science and faith are allies in the pursuit of truth—the truth about God's glorious creation.
"Great are the works of the LORD; they are pondered by all who delight in them."
— Psalm 111:2
Discussion Questions
