Do science and Christianity conflict?

The assumption that science and Christianity are at war is so widespread that most people never examine it. Historians of science largely reject it.

Where the warfare story came from

Two nineteenth-century books did most of the work: 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).

Both are now regarded by historians as polemics rather than history. White in particular invented or badly distorted a series of episodes, including the claim that medieval Christians believed in a flat earth — they did not; educated Europeans had known the earth was spherical since antiquity, and Columbus's dispute was about the planet's size.

Ronald Numbers' edited volume Galileo Goes to Jail and Other Myths about Science and Religion — written by secular historians of science, not apologists — works through twenty-five of these myths.

Christianity as a condition for science

The historical case is stronger than most Christians realise, and it runs the other way.

Modern science emerged in one civilisation, once, and stayed. The philosopher Alfred North Whitehead — not a Christian — argued that this was no accident: it required the widespread conviction that nature is orderly, and that conviction came from belief in a rational Creator.

The assumptions modern science requires:

The universe is orderly and intelligible. If nature were capricious, or the plaything of competing deities, systematic investigation would be pointless. Christians expected order because they expected a lawgiver.

Nature is not divine. In animist and pantheist frameworks, dissecting or experimenting on nature is impious. The doctrine of creation de-divinises nature — it is made, not god — which makes it available for study.

Empirical investigation is necessary. God could have made the world any number of ways, so you cannot deduce it from first principles as the Greeks tried to. You have to go and look. Kepler called it thinking God's thoughts after him.

Human minds can know. Beings made in the image of a rational God have faculties aimed at truth.

The founders reflect this: Copernicus, Kepler, Galileo (a lifelong Catholic), Boyle, Newton (who wrote more on theology than physics), Faraday, Mendel (a friar), Pasteur, Maxwell, Kelvin. And in the twentieth century Georges Lemaître, a Belgian Catholic priest, proposed the theory that became the Big Bang — and had to argue against Einstein's preference for an eternal universe.

The Galileo case as it happened

Since it is the standard example, it is worth getting right — and getting right means conceding a great deal.

What is true: Galileo was correct. The church treated him badly. He was tried by the Inquisition in 1633, forced to recant, and spent his final years under house arrest. The church was wrong and eventually said so.

What is usually omitted: Heliocentrism had been published by Copernicus, a cleric, in 1543 without incident and with a dedication to the Pope. Jesuit astronomers confirmed Galileo's telescopic observations and honoured him. Pope Urban VIII was a friend and patron who had written poetry in his praise.

The conclusive evidence — stellar parallax — was not observable until 1838, and Galileo's own proposed proof, based on the tides, was wrong. He was right for reasons he could not yet demonstrate.

The Pope had asked him to present heliocentrism as a hypothesis. Galileo instead published a dialogue in which the Pope's own argument was given to a character named Simplicio — the simpleton. This was, at minimum, a serious political misjudgement.

And his "house arrest" was in a comfortable villa, where he wrote his most important scientific work. He was not tortured or imprisoned in a dungeon.

None of this excuses the church. It does show that the episode was about politics, personality, jurisdiction and premature certainty — not a clean confrontation between reason and faith.

What science can and cannot address

John Lennox's distinction is the most useful thing in this whole area:

Explaining a mechanism does not eliminate an agent.

Understanding the internal combustion engine does not make Henry Ford unnecessary or imaginary. Both explanations are complete and both are true, because they answer different questions.

Science answers: how does this work? what is it made of? what happens if I change this?

Science cannot answer: why is there anything rather than nothing? what is a person for? is anything genuinely wrong? what is beautiful? does my life matter?

These are not gaps awaiting future research. They are outside the method — not because science is deficient, but because it was designed for a different purpose.

Scientism — the claim that scientific knowledge is the only real knowledge — is not science but a philosophical position, and it is self-refuting: the claim is not itself established by any experiment.

Genesis and the age of the earth

What every orthodox position affirms: God created deliberately, creation is good, humanity uniquely bears God's image, and the fall was real.

None of this is in the creeds. Nicaea says God is "maker of heaven and earth" and stops. Making the mechanism a test of fellowship goes beyond what the church has ever required — and has driven a considerable number of young people out of the faith when they encountered evidence they had been told was impossible.

Augustine's warning, from AD 415

This is worth quoting at length because it was written sixteen centuries ago and has not aged:

Even a non-Christian knows something about the earth, the heavens... and this knowledge he holds to as being certain from reason and experience. Now, it is a disgraceful and dangerous thing for an infidel to hear a Christian, presumably giving the meaning of Holy Scripture, talking nonsense on these topics... If they find a Christian mistaken in a field which they themselves know well and hear him maintaining his foolish opinions about our books, how are they going to believe those books in matters concerning the resurrection of the dead, the hope of eternal life, and the kingdom of heaven?— Augustine, The Literal Meaning of Genesis

Augustine's concern was not that Christians should adopt whatever science says. It was that overclaiming about the natural world costs credibility on the things that matter most.

How to handle the conversation

Do not concede the framing. "Science versus faith" is not a real division; the question is always which specific claim.

Ask what specifically conflicts. Usually the answer is evolution, occasionally the Big Bang — which, ironically, was resisted by atheists precisely because it implied a beginning.

Distinguish science from philosophy. "Natural selection explains the diversity of life" is a scientific claim. "Therefore there is no God and life has no purpose" is a philosophical addition riding on it. Point out where the transition happens.

Name the believing scientists. Francis Collins led the Human Genome Project and wrote a book about coming to faith. Lemaître proposed the Big Bang. John Polkinghorne was a Cambridge particle physicist who became a priest. The claim that scientists cannot believe is a claim about the world that is straightforwardly false.

Be honest where the questions are genuinely hard. The relationship between Genesis and natural history, the historicity of Adam, the problem of animal suffering before the fall — these are real questions with serious Christians on different sides.

What the heavens are doing

"The heavens declare the glory of God, and the sky above proclaims his handiwork" (Psalm 19:1).

The Christian claim is not that the universe is a mystery to be protected from investigation. It is that it is a work — and that studying it carefully is a way of paying attention to the one who made it.

"It is the glory of God to conceal things, but the glory of kings is to search things out" (Proverbs 25:2).

Kepler, who spent his life on planetary orbits and got there by discarding his own most cherished theory when the data refused, described the whole enterprise as thinking God's thoughts after him.

That is not a truce between two enemies. It is a description of what the work was for.
