Some people see science and religion as enemies, at war for leadership in our modern culture. Others see science and religion as completely separate and unrelated facets of life. However, science is not the only source of facts, and religion reaches beyond the realm of values and morals. In fact, religion can have a positive impact on science, such as in the development of modern medical ethics. Many early scientific leaders were devout Christians, as are some scientific leaders today. Science can also enhance the spiritual life of believers. Christians rejoice in scientific discoveries that reveal the glory of God the creator.
When creation and evolution clash in a courtroom, the daily news fills up with stories suggesting that there is some profound conflict between science and Christianity. Inevitably, someone mentions the historical incident of Galileo. Galileo was charged with heresy by the church in 1633 for teaching that the Earth orbits the Sun. From Galileo to textbook battles, the hasty conclusion is that science and Christianity are engaged in an endless debate, fundamentally opposed to each other.
Yet the Galileo incident and today’s conflicts are often about much more than the particular claims of science or faith. Personalities, politics, and culture wars all come into play when drawing the battle lines. In many instances, science and scientists are not themselves in conflict with Christian belief. In fact, Galileo himself was a Christian who believed “that the glory and greatness of Almighty God are marvelously discerned in all His works and divinely read in the open book of Heaven”1 Many scientists then and now2 are Christians who see no conflict between their scientific work and their faith. Most things studied via the natural sciences—such as the migration patterns of birds or the interior of atoms—do not raise any theological or biblical concerns.
The “warfare” model, then, is not very helpful for understanding evolution and Christianity, since it assumes conflict from the start. A few particular areas of scientific study—like the big bang and evolution—do raise concerns for Christians, but much of the BioLogos website is devoted to showing that evolution and Christianity are not truly at war. In the rest of this answer, we’ll explore other models for the working relationship between science and Christianity.
Are Christianity and science completely separate?
One way to erase the conflicts between science and Christianity is to view them as entirely separate endeavors, with different purposes, methods, and bodies of knowledge. This view emphasizes that science is a system of knowledge about the world and its behavior, whereas religion is about morality, God, and the afterlife. Thus, Christianity and science cannot conflict, because they are addressing different sorts of questions.3
This model has some weaknesses (see below), but it does help us understand some important aspects of the relationship. Many apparent conflicts between science and religion occur because of a lack of understanding of the fundamental differences between the two. When someone claims that the Bible answers a scientific question, and another claims that science answers a question about God, the conflict immediately flares up. Many conflicts become enflamed because participants forget that Christianity and science do generally address very different questions.
This model also reminds us that science is not the only source of knowledge. There are many sorts of questions that simply do not fall under the domain of science. Borrowing an example from the Rev. John Polkinghorne, there is more than one answer to the question of “Why is the water boiling in the tea kettle?”4 The scientific answer might be “the water is boiling because at this temperature it undergoes a phase transition from liquid to vapor.” Another acceptable, though nonscientific, answer is “the water is boiling because I put the kettle on the stove.” A third answer might be “the water is boiling because my prayer partner is coming over for tea.” None of the answers is wrong; rather, each gives a different perspective on the question. The scientific answer does not tell the whole story. Science cannot answer questions like “Is my friend trustworthy?” or “Is this poem well-written?” Science is tremendously successful in understanding the physical world, but we should not let that tempt us to think it can be used to understand everything in life.
Science cannot answer the question “Does God exist?” Some people argue that God’s existence is actually a scientific claim that could be tested like a chemical reaction. But science studies the natural world, not the supernatural. No amount of scientific testing or theorizing could prove or disprove the existence of a supernatural creator. The claim that “God exists” is a metaphysical one, not a claim about nature or physical laws
This model also reminds us that the Bible is not the only source of knowledge. The Bible is silent on most of the topics that concern scientists, like protons, photosynthesis, penguins, and Pluto. The Bible is not a science textbook, in the same way that it is not a textbook of plumbing, agriculture, or economics. Instead, God teaches us about these things through his general revelation in the created order.
However, this model has some significant weaknesses. It isolates religion from science, which can be a first step in marginalizing religion from public discourse. By defining religion and science as separate, this model doesn’t help us understand the interactions they do have, either negative or positive. The model also sets science on its own, apart from religion, while Christians believe that no part of our lives is outside of our walk with God.
Science and Christianity interact, correcting and enhancing each other
While many questions can be clearly categorized as “science” questions or as “Bible” questions, other questions are on the boundary. For topics like evolution, medical ethics, and climate change, we need to consider both science and faith when seeking out God’s truth. For such complex questions, we need all the knowledge and wisdom we can get, rather than handicapping ourselves by looking only to science or only to the Bible. If we look to only one or the other, we will get a distorted view of the issue. As Pope John Paul II wrote,
“Science can purify religion from error and superstition; religion can purify science from idolatry and false absolutes. Each can draw the other into a wider world, a world in which both can flourish.”5
God reveals himself in the book of Scripture and the book of Nature. To learn more about God and his work, we study both books. When one book is confusing or ambiguous, insights from the other book can help us understand it. In both revelations, we look for the underlying truth of who God is and how he made the world. Rev. John Polkinghorne wrote, “Science and theology have things to say to each other, since both are concerned with the search for truth attained through motivated belief.”6

Science can purify religion from error and superstition; religion can purify science from idolatry and false absolutes. Each can draw the other into a wider world, a world in which both can flourish.
Faith can have a positive impact on science by guiding the practical application of scientific discoveries. With the rapid advance of science and technology, many ethical questions are facing our society. Development of safe nuclear energy is not far from the development of nuclear weapons, new medical imaging techniques save lives but are too expensive for the poor, and DNA testing improves treatment of genetic disorders at the risk of the results being misused.7 To address these complex questions, we need both science and the moral grounding of religion. We can’t just give a quick answer from the Bible without studying the scientific complexities, nor can we look to science alone to guide ethical decisions. Christianity and other religions lay the groundwork for the moral standards that are essential for the appropriate use of science and technology.
Science also has a positive impact on the faith of the believer. The Bible teaches that “The heavens declare the glory of God” (Psalm 19:1). Christians see God’s glory when looking up at the stars, and in colliding galaxies seen through a telescope. God’s glory is revealed in the beautiful symmetry of a maple leaf, and in the complex biochemical activity inside each cell in that leaf. Science and technology have shown us much more of God’s creation than was known in biblical times, revealing more and more of God’s glory.
Finally, Christianity can provide the belief framework for how and why we do science. Christians need not set aside their faith when they sit down to do science.

We need your help.
As Christians, we know through God’s Word how much he loves us—that we are ”fearfully and wonderfully made” and to be image bearers among his expansive, divine creation.
Sadly, this view isn’t always accepted among the church and the world.
Many Christians today still don’t accept the findings of modern science, and that affects everything from caring for God’s creation to getting vaccinated. Many are also departing or rejecting the faith over the perceived science and faith conflict.
This is where you can help.
BioLogos has become a trusted resource for so many who may have a fear or distrust in science. But we need to do more. With your gift to our summer fundraising campaign, we can show how science and faith work hand in hand to create a better world.
