The War Between Science and Theology

The War Between Science and Theology

Yesterday we talked about how Eratosthenes accurately computed Earth’s circumference around 240 B.C. We also said that it is a myth that people in the middle ages and even in the time of Christopher Columbus believed that the world was flat. That myth was based on a fiction story about Columbus written by Washington Irving in 1828. The myth was reinforced by a scientist and a historian who initiated a war between science and theology.

Scientist and philosopher John William Draper wrote History of the Conflict Between Religion and Science in 1874. He claimed that the Church was hostile to the advancement of science. He claimed that the early Church fathers believed that scripture said the Earth is flat. That concept of a war between science and theology was further advanced and popularized by historian Andrew Dickson White in his book The Warfare of Science (1876). Darwin had published his work On the Origin of Species in 1859, and the war was on.

Creating a war between science and faith seems to have been a goal of Draper and White and many advocates of Darwin’s theory, such as Thomas Henry Huxley. The lack of scholarship on the part of Draper and White has been demonstrated. Meanwhile, Darwin’s theory has had to be revised to what is now known as Neo-Darwinism. Darwin thought that living cells were just globs of protoplasm. He had no idea that they are more like cities with factories, machines, and transportation systems operating on complex information contained in DNA. As biological science advances, Darwinian naturalism faces more challenges.

Historians of science David Lindberg and Ronald Numbers wrote in Beyond War and Peace: A Reappraisal of the Encounter between Christianity and Science (1986) that “there was scarcely a Christian scholar of the Middle Ages who did not acknowledge [Earth’s] sphericity and even know its approximate circumference.” What many writers, including Draper and White, had overlooked was that the leading early scientists were believers in God. In fact, their faith motivated their desire to know God through His creation.

We can still know God through His creation today. So the idea of a war between science and theology is not accurate. Science and faith are friends. “For his invisible attributes, that is, his eternal power and divine nature, have been clearly seen since the creation of the world being understood through what he has made” (Romans 1:20 CSB).

To Accurately Calculate Earth’s Circumference

To Accurately Calculate Earth’s Circumference

How was a man living over 2,000 years ago able to accurately calculate Earth’s circumference? How could he even know that Earth is spherical? How can some people today believe that our planet is flat when everyone has seen pictures of Earth taken by satellites in space?

Those may be too many questions at once. Let’s try looking at them one at a time. The first man to accurately calculate Earth’s circumference in about 240 B.C. was a Greek polymath named Eratosthenes. He was a brilliant mathematician, geographer, astronomer, music theorist, and poet, and his calculations were amazingly accurate.

A myth originated from a fiction work by nineteenth-century American author Washington Irving and other authors. Irving wrote a less-than-accurate “biography” of Christopher Columbus. In it, the Spanish authorities questioned Columbus’ plan to sail west to Asia by going east because they thought the ships would drop off the edge of a flat Earth. The truth is that European scholars at that time knew that our planet is a sphere. In fact, Columbus did too, but he believed that it was 25% smaller than it actually is. He should have paid more attention to Eratosthenes.

Ancient Greek scholars, as early as the fifth century B.C., recognized the spherical nature of the planet based on observations. (We have talked about that before.) So Eratosthenes set out to accurately calculate Earth’s circumference. Let’s look at a simplified description of how he did it.

Eratosthenes was the librarian of the famous library of Alexandria in Egypt. Syrene was a city 5,000 stadia south in what is now Aswan, Egypt. (5000 stadia was approximately 800 km or 497 miles.) At noon on the summer solstice, Eratosthenes placed a rod vertically into the ground in Alexandria. At the same time, his assistant had placed a rod of the same length at Syrene. Since Syrene is very close to the Tropic of Cancer, where the Sun is directly overhead at noon on the solstice, the rod did not leave a shadow. In Alexandria, the rod produced a shadow of 7 degrees, which is 1/50 of the circumference of a circle. That means Earth’s circumference would be 50 times the distance from Alexandria to Syrene. Multiplying 50 times 5,000 stadia results in 250,000 stadia for Earth’s circumference. Depending on exactly how long a stadion was, that measurement is accurate to within -2.4% to +0.8%.

That answers the first two questions, but what about people today who believe the Earth is flat when there is plenty of evidence otherwise? That is an example of people believing what they want to believe and refusing to accept the evidence. There is a connection here to the so-called war between science and faith, and it relates to what we read in Romans 1:20. More on that tomorrow.

Earth Is Not Flat

Earth Is Not Flat
There is a myth that when Columbus set out on his famous voyage, people believed he would sail off the edge of the Earth. According to the myth, only the voyage of Columbus convinced people that the Earth was not flat. That myth is not true, and Earth is not flat.

The myth came from an early historical fiction work by Washington Irving in 1828. At the time of Columbus in 1492, educated Europeans knew that our planet is a sphere. The Greek philosopher Aristotle recognized that fact in 330 B.C. He observed that when lunar eclipses occurred, the shadow Earth cast on the Moon was always a semicircle. That could only happen every time if the Earth were a sphere. Also, it was easy to observe that when a ship came into shore over the ocean, the first part to be visible was the top of the sail. As it came closer, the lower part could be seen. That shows the curvature of the ocean surface.

In the early Church period, the view of a spherical Earth was widely accepted. The Christian theologian and philosopher Augustine (354-430) recognized that Earth was spherical. Theologian Thomas Aquinas (1225-1274) acknowledged that physics, astronomy, and mathematics had proven that Earth is a sphere.

However, the Quran (609-632) says that the Earth was “laid out,” “spread out,” or “made flat” depending on how it’s translated. In the sixteenth century, a Sunni commentary stated that most Muslim scholars took those words to mean the Earth is flat. Chinese society did not let go of the concept of a flat Earth until the seventeenth century when Jesuit scholars brought their teaching to that country.

In spite of the evidence some people today insist that the Earth is flat. There is another persistent myth that science and the Bible are enemies and that they contradict each other. We believe that true science and the Bible correctly understood cannot contradict each other because they have the same Author. Earth is not flat, and science and the Bible are friends, not enemies.
