Flat Earth Theory: When Distrust Is Mistaken for Faith

By Andre Eksteen

People often become divided in their faith over matters that do not touch the core at all. One of the clearest examples of this in our time is the idea that the earth is flat. What begins as curiosity quickly hardens into conviction, and for some it even becomes a test of “true” Christianity. If you question it, you are accused of being compromised, deceived, or not taking the Bible seriously enough.

But when we step back and look at this honestly, without fear and without defensiveness, the idea simply does not hold water.

The flat earth theory is not a rediscovered biblical truth. It is not an ancient Christian belief that was suppressed. It is not rooted in Scripture, in the early Church, or in the Hebrew understanding of creation. It is a modern reactionary idea that has been retrofitted with Bible verses after the fact. That distinction matters.

The idea may sound biblical to some people because it borrows biblical language, but borrowing words is not the same as respecting meaning. When Scripture is treated as a technical manual instead of a revelation of God, it gets twisted into something it was never meant to be.

So where did this idea actually come from?

The modern flat earth movement does not arise from the early Church, from ancient Judaism, or from any serious biblical tradition. Its roots are surprisingly recent. It emerged in the nineteenth century among a very small group of individuals who deliberately positioned themselves against established knowledge, not because Scripture demanded it, but because distrust had become their guiding principle.

The central figure in this movement is Samuel Rowbotham (1816–1884), an English writer who promoted what he called Zetetic Astronomy. His method was simple: only trust what you believe you can see with your own eyes, and reject anything that requires mathematics, instruments, or cumulative knowledge.

Rowbotham argued that because water appears level to the eye, the earth must be flat. From that single assumption, he dismissed astronomy, geometry, gravity, and later even photography. His approach was not biblical exegesis. It was not historical theology. It was personal intuition elevated to absolute authority.

That is the key problem.

Rowbotham did not begin with Scripture and ask what it teaches. He began with a conclusion and then searched for verses that could be forced to support it. This is not how truth is discovered. It is how ideologies are built.

From Rowbotham’s ideas, later groups developed, most notably the Flat Earth Society, which was revived in the twentieth century. Importantly, this revival did not happen among theologians, biblical scholars, or church historians. It happened among individuals who were deeply distrustful of authority in general. In many cases, it was tied to anti-institutional, anti-scientific, and often explicitly anti-Christian worldviews.

With the rise of the internet, these ideas found fertile ground. Distrust spreads faster than understanding, especially in communities already suspicious of governments, universities, and historical consensus. A theory does not need to be true to spread; it only needs to confirm existing suspicion. And suspicion sells.

Only much later did some Christian groups begin to adopt flat earth ideas. When that happened, something genuinely dangerous occurred: a secular conspiracy theory was repackaged as a test of faith.

Once that line is crossed, disagreement is no longer intellectual; it becomes moral. If you reject the theory, you are told you reject Scripture. If you question it, you are told you question God. Faith is no longer anchored in Christ but in a model of the cosmos.

That is why flat earth belief today has very specific characteristics. You mostly find it among small, loosely connected groups with no historical continuity. You find no roots in Church history. You find no support from Hebrew language studies. And you will not find a single early Church Father who ever taught it.

This point cannot be overstated.

No early Church Father believed in a flat earth. Not Augustine, not Origen, not Thomas Aquinas. On the contrary, they accepted the earth’s spherical nature as self-evident, drawing both from Scripture and from the natural knowledge available in their time.

The idea that Christians once universally believed in a flat earth is itself a modern myth.

The conclusion so far is straightforward. The flat earth idea is not ancient. It is not biblical. It is not ecclesiastical. It is a modern reactionary movement that confuses distrust with insight and certainty with faith. And when faith begins to feed on distrust, it does not become deeper. It becomes smaller, tighter, and more fearful.

At this point, flat earth advocates usually turn to Scripture.

They point to verses like “the four corners of the earth” or “the ends of the earth” and insist these are technical descriptions. But this reveals a fundamental misunderstanding of how language works, including biblical language.

We still speak today of the sun “rising” and “setting,” even though we know the earth is rotating. No one accuses us of lying or ignorance when we use that language. It is phenomenological language: describing how things appear from a human perspective.

The Bible does the same.

Let us look at the Scriptures most often cited.

Isaiah 40:22 says, “It is he that sitteth upon the circle of the earth…”

The Hebrew word translated as “circle” is chûg. This word does not describe a flat disc. It refers to a rounding, an encircling, a curvature. It is used elsewhere to describe the vault of the heavens and the horizon itself. A flat surface does not have a chûg. Only something with curvature does.

If Isaiah had intended to describe a flat plane, Hebrew had words available for that. He did not use them.

Job 26:10 says, “He hath compassed the waters with bounds, until the day and night come to an end.”

This is an astonishingly accurate description of a spherical earth. Day and night move continuously around the globe, forming a shifting boundary. On a flat earth, there is no consistent circular division between light and darkness. There is only a spotlight model, which does not match what the text describes.

Ecclesiastes 1:6 continues, “The wind goeth toward the south, and turneth about unto the north; it whirleth about continually…”

This is global circulation. Winds do not behave this way on a flat, static plane. This verse reflects an understanding of cyclical movement, not randomness.

Job 26:7 adds another layer: “He stretcheth out the north over the empty place, and hangeth the earth upon nothing.”

This statement alone dismantles every ancient flat-earth cosmology. In ancient mythologies, flat earths rest on pillars, animals, or foundations. Scripture explicitly denies that. The earth “hangs.” It is unsupported, suspended in space.

Then there is the testimony of Jesus Himself.

In Luke 17:34–36, Jesus describes people experiencing different activities at the same moment: one in bed, another grinding grain, another working in the field. This only makes sense if night and day are occurring simultaneously in different locations. On a flat earth under a single sun, this is impossible.

This is not incidental language. It reflects an assumed reality.

Scripture, when read carefully, consistently aligns with a spherical earth without ever making it the point. That is precisely what we would expect if the Bible is not a science textbook but a truthful revelation.

When we move beyond the Bible to the ancient world surrounding it, the picture becomes even clearer.

Centuries before Christ, thinkers such as Pythagoras taught that the earth is spherical. Aristotle confirmed this through observable phenomena: the curved shadow of the earth during lunar eclipses and the changing position of stars as one travels north or south.

In the third century BC, Eratosthenes calculated the circumference of the earth with remarkable accuracy using nothing more than shadows and geometry. This was not hidden knowledge. It was known, discussed, and taught long before the New Testament was written.

These men lived in the same world as the biblical authors. The idea of a round earth was not shocking, heretical, or forbidden. It was part of the intellectual environment.

Ironically, the belief that ancient people thought the earth was flat is itself a modern invention, popularised in the nineteenth century to portray religion as ignorant and science as its rescuer. Flat earth theory ends up agreeing with that false narrative instead of challenging it.

Today, this is no longer merely theoretical. We observe the earth directly. Satellites orbit it. GPS systems function because the earth is spherical. Weather patterns, flight paths, and time zones all depend on it. These are not guesses or artistic renderings. They are operational realities.

If the earth were flat, global navigation would fail. Satellite communication would collapse. None of the systems we rely on daily would work as they do.

The real issue, then, is not the shape of the earth.

The real issue is what happens when believers attach their faith to something that is not the gospel. When that happens, faith becomes defensive instead of confident, fearful instead of grounded, closed instead of truthful.

The Bible was never given to explain orbital mechanics. God revealed Himself, not a physics syllabus. When we demand that Scripture answer questions it was never intended to answer, we weaken it instead of honouring it.

If someone feels the need to test their faith on the shape of the earth, they have already missed both the test and the faith. The gospel does not stand or fall with cosmology. It stands or falls with truth.

And truth does not need to be flattened in order to survive.
