Earlier this month, on Good Friday (April 3rd, 2026), I visited a Shroud of Turin exhibit here in the Houston area—and the experience has stayed with me ever since. Standing before the life‑sized image of a crucified man, I was struck by how closely the details align with everything the Gospels describe about the suffering, death, burial, and resurrection of Jesus Christ.
The wounds. The scourging. The crown of thorns. The pierced wrists and feet. The side wound. The burial posture. The blood serum separation consistent with post‑mortem flow.
It all lines up.
I’ll be honest: I would love to believe this is truly the image of our Lord and Savior Jesus Christ. I think I may be closer to that conviction than ever before.
The historical, scientific, and forensic details presented by Dr. Jeremiah Johnston—who earned his PhD at Oxford and once considered the Shroud a medieval forgery—are powerful, compelling, and hard to ignore. He openly admits that he was conditioned for years to accept the 1988 radiocarbon dating as decisive. But after examining the broader body of evidence, he now says:
“It turns out, when you look at it, the Shroud of Turin is scientific proof of the physical bodily resurrection of Jesus Christ. I believe that based on the evidence in the 102 academic disciplines that have studied over 600,000 research hours in it. So I went from skeptic to believing in it based on the science.”
He also says, “I believe based on the evidence, because I am not irrational.”
Those are strong statements.
For him, the Shroud is not a leap of blind faith; it is a conclusion drawn from the weight of scientific, historical, and forensic data, and yet, like the Apostle Thomas, I’m still wrestling with that final step of clarity and certainty as it relates to the authenticity of the Shroud of Turin.
The 1988 radiocarbon test, which dated a corner sample of the cloth to between AD 1260 and 1390, has never been officially overturned by scientific consensus. A 2024 study has effectively reopened the case and created what you might call a “conflict of evidence”—raising serious questions about the reliability of the original sample and methodology—but it has not yet provided the kind of “smoking gun” that forces the scientific world to discard the 1988 results entirely.
So where does that leave someone like me—someone who loves Jesus, loves truth, and wants to believe with integrity?
It leaves me doing what Thomas did: staying close, asking honest questions, and refusing to pretend certainty where I don’t yet have it.
The Case Against Authenticity: What Still Needs to Be Faced Honestly
If we’re going to talk about the Shroud of Turin with integrity, we can’t just share the evidence that supports authenticity. We also have to acknowledge the evidence that seems to argue against it.
1. The 1988 Radiocarbon Test (AD 1260–1390)
In 1988, three laboratories (Oxford, Zurich, and Arizona) tested a small corner sample of the Shroud and concluded that the cloth dated between AD 1260 and 1390. That result, on its face, places the Shroud in the medieval period—centuries after the time of Jesus.
Later critiques have raised serious concerns about:
Sampling location: The tested area may have been from a corner that was repaired in the Middle Ages.
Contamination: Fibers may have been contaminated by handling, fires, or later additions.
Textile anomalies: Cotton fibers interwoven with linen in the tested area suggest it may not represent the original cloth.
Still, despite these challenges and the 2024 study reopening the question, the 1988 result has not been formally overturned by a broad scientific consensus. That matters.
2. Gaps in the Early Historical Record
While early Christian sources mention burial cloths of Jesus, the Shroud’s clearly documented history becomes solid only in the 14th century. Skeptics argue that the lack of an unbroken, explicit chain of documentation from the first century to the Middle Ages weakens the case for authenticity.
3. Artistic or Technological Theories
Some have proposed that the Shroud is:
a medieval painting,
a bas‑relief rubbing,
or even an early form of “proto‑photography.”
To date, none of these theories has successfully reproduced all the Shroud’s unique properties, but they remain part of the skeptical landscape and can’t simply be waved away.
If we’re going to be honest, we have to say: there is real evidence that raises questions, and it hasn’t all been neatly resolved.
What Dr. Jeremiah Johnston Says About the 1988 Carbon Dating
In a recent interview with Dr. Frank Turek, Dr. Jeremiah Johnston addressed the 1988 radiocarbon test directly — and his explanation is worth hearing in full. He began by noting that many people (and even AI tools) simply repeat the claim that the Shroud is a medieval forgery without ever engaging the actual science. As he put it, “You have to actually deal with the science.” Skepticism alone is not evidence.
Johnston explained that the medieval world was overflowing with relics, and many Christians were understandably skeptical of them. But that cultural skepticism does not determine truth. Only the data does.
When it comes to the 1988 carbon dating, Johnston is blunt:
“1988 was utterly corrupt dating.”
Here’s why:
Seven laboratories were originally supposed to test the Shroud. Only three did.
STURP specifically warned the Vatican not to carbon date the edges, because they had been repaired and reinforced over the centuries.
Despite this, the labs were given a sample from the top left corner — the exact area known to be patched.
Even modern replicas fall apart at the edges, requiring reinforcement. The real Shroud’s edges are unquestionably altered.
The British Museum then suppressed the raw data for 27 years.
When the data was finally released, independent researchers demonstrated that the tested fibers were not homogeneous with the rest of the Shroud.
A 2019 peer‑reviewed study in the Journal of Archaeometry (the same journal that originally published the 1988 results) concluded that the carbon‑dated samples were contaminated and unreliable.
Johnston summarized the situation this way:
“If you were to pile up all the scales of truth, don’t use the carbon dating.”
In other words, the 1988 test did not settle the question — it complicated it. Additionally, modern science has now shown that the sample used in 1988 simply cannot be treated as representative of the Shroud itself.
The Case for Authenticity: Evidence That Demands to Be Taken Seriously
On the other side, there is a massive body of evidence that is not so easily dismissed. Much of it comes from the Shroud of Turin Research Project (STURP)—a team of 33 scientists who examined the Shroud in 1978—and from the work and testimony of Barrie Schwortz, STURP’s official documenting photographer.
Many of these researchers began as skeptics. They did not set out to prove the Shroud authentic. In some cases, they expected to expose it as a forgery. What they found instead left them with more questions than answers—and, for some, a transformed faith.
1. The Image Is Not Paint, Pigment, or Dye
STURP’s analysis concluded that:
There is no paint, pigment, dye, or stain forming the image.
No binders (like oil or egg) are present.
No brush strokes or directionality can be detected.
The image is a superficial discoloration of only the topmost fibrils of the linen—less than a fraction of a human hair in depth. It is not something applied to the cloth; it is a change in the cloth itself.
No known artistic technique, medieval or modern, can fully replicate this.
2. The Image Contains Three‑Dimensional Information
This was one of the discoveries that deeply impacted Barrie Schwortz.
When the Shroud image was processed through a NASA‑developed device called the VP‑8 Image Analyzer, it produced a coherent three‑dimensional relief—a topographical map of the body.
Normal photographs do not do this. Paintings do not do this. Drawings do not do this.
Only the Shroud does.
For Schwortz, this was a turning point. It convinced him that the image was not the work of an artist and not a simple photograph. It was something else—something we still don’t fully understand.
3. The Blood Is Real, Human, and Forensically Consistent
STURP and subsequent studies have shown that:
The blood on the Shroud is real human blood.
It is Type AB, a relatively rare type globally but more common in the Middle East.
The blood shows high levels of bilirubin, consistent with severe physical trauma.
The bloodstains formed before the image, meaning the image did not create the blood patterns.
The blood flows and patterns are consistent with:
scourging,
a crown of thorns,
nails through the wrists and feet,
and a spear wound in the side.
In other words, the blood evidence matches exactly what the Gospels describe.
4. Anatomical and Forensic Accuracy
Medical and forensic experts have noted that:
The scourge marks match the pattern of a Roman flagrum.
The nail wounds are in the wrists, not the palms—consistent with Roman crucifixion practice and the need to support body weight.
The side wound is consistent with a Roman spear thrust.
The blood flows follow gravity in ways that match a body first upright on a cross and then lying in burial position.
There are no signs of decomposition, suggesting the body did not remain in the cloth long.
This is not the kind of anatomical detail a medieval artist would likely have known or been able to reproduce with such precision.
5. The Image Formation Remains Unexplained
STURP’s final report famously concluded:
“We can state with confidence that the Shroud image is not the product of an artist. The image is an ongoing mystery.”
Some researchers have proposed that the image may have been formed by a burst of radiant energy—something that, for believers, resonates with the idea of resurrection. But scientifically, the mechanism remains unknown.
The key point is this: no one has yet been able to reproduce the Shroud’s image with all its properties using any known method.
The Sudarium of Oviedo: A Second Cloth That Corroborates the Shroud
One of the most compelling pieces of corroborating evidence emphasized by Dr. Jeremiah Johnston and many Shroud researchers is the Sudarium of Oviedo—a smaller, blood‑stained cloth kept in the Cathedral of San Salvador in Oviedo, Spain.
The Gospel of John mentions a separate face cloth in the tomb:
“The face cloth, which had been on Jesus’ head, not lying with the linen cloths but folded up in a place by itself.” (John 20:7)
The Sudarium is believed by many to be that face cloth.
1. A Strong Historical Chain of Custody
Unlike the Shroud, the Sudarium has a remarkably well‑documented history:
It was reportedly kept in Jerusalem until around AD 614.
It was moved to protect it from the Persian invasion.
It eventually arrived in Spain and has been documented in Oviedo since at least the 7th century.
This gives the Sudarium over 1,300 years of continuous historical documentation, making it extremely unlikely to be a medieval invention.
2. The Blood on the Sudarium Matches the Blood on the Shroud
Forensic studies have shown that:
Both the Shroud and the Sudarium contain Type AB blood.
The blood chemistry, including trauma indicators, is consistent across both cloths.
The blood flow patterns correspond to the same kinds of head wounds.
This is not generic similarity—it is forensically specific.
3. Over 100 Points of Congruence in Bloodstain Patterns
Forensic pathologists have mapped the bloodstains on the Sudarium and compared them to the facial area of the Shroud. They have identified over 100 points of congruence between the two.
In forensic science, far fewer points of congruence are often enough to match fingerprints or patterns.
The conclusion many draw is that both cloths likely covered the same individual.
4. The Sudarium Has No Image—Which Actually Supports Authenticity
Unlike the Shroud, the Sudarium bears no image—only blood and bodily fluids.
This is important because:
A medieval forger trying to create a convincing relic would have no reason to produce a second cloth with no miraculous image.
The Sudarium’s existence and properties support the idea that the Shroud’s image was formed later, after the Sudarium was removed—consistent with the timing of burial and resurrection.
For many researchers, the Sudarium is one of the strongest external confirmations that the Shroud is not a standalone oddity, but part of a larger, historically and forensically coherent picture.
Barrie Schwortz: From Jewish Skeptic to Believer in Jesus
In his TED Talk and other presentations, Barrie Schwortz shares how the Shroud—and the evidence surrounding it—changed his life.
He began as a Jewish photographer who walked away from Judaism at a young age; he was not a Christian, and certainly not someone predisposed to believe in the resurrection of Jesus. He expected to document a medieval forgery.
What changed him?
The 3D information in the image.
The absence of pigments, dyes, or paints.
The forensic accuracy of the wounds and blood flows.
The superficiality of the image on the linen fibers.
The corroborating evidence of the Sudarium of Oviedo.
Over time, he became convinced that:
“The Shroud is authentic. And if the Shroud is authentic, then the man on the Shroud is Jesus.”
Schwortz has openly testified that the Shroud played a major role in his journey to believing in Jesus Christ.
That doesn’t make the Shroud true by default—but it does show how powerful the evidence can be when examined honestly.
Why I Believe Renewed Scientific Testing Is Necessary
All of this brings me back to the tension I feel—the “Doubting Thomas” place I find myself in.
On one hand, the Shroud’s image, wounds, and forensic details match the Gospel accounts with astonishing precision. The work of STURP, the testimony of experts like Dr. Jeremiah Johnston, the corroborating evidence of the Sudarium of Oviedo, and the journey of someone like Barrie Schwortz all point strongly in the direction of authenticity.
On the other hand, the 1988 radiocarbon test still stands as a major unresolved obstacle — once considered decisive — has now been shown to be scientifically unreliable. The 2024 study has reopened the case and created a genuine conflict of evidence, but it has not yet delivered the definitive, universally accepted overturning of the 1988 result.
That’s why I believe it’s time for the Catholic Church to allow renewed, carefully controlled scientific testing on the Shroud of Turin.
If this cloth is truly from the first century, then let’s verify it with updated methods and better sampling. If it isn’t, then let’s be honest about that too.
I would much rather have a Shroud with a few carefully removed samples—and rock‑solid, beyond‑dispute confirmation that it dates to the time of Jesus—than a perfectly preserved relic that remains scientifically inconclusive or still tied to a 15th‑century result.
Truth doesn’t need to be protected from investigation.
If the Shroud is authentic, further testing will only strengthen that case. If it’s not, then we should have the integrity to say so.
Faith and Honest Inquiry Can Walk Together
So where does that leave me today?
I’m not rejecting the Shroud. I’m not blindly accepting it either.
I’m embracing both faith and honest inquiry.
I’m hopeful. I’m open. I’m simply seeking the truth with integrity.
If the Shroud is real, I want to embrace it wholeheartedly. If it’s not, I want to be honest about that too.
Either way, my faith in the risen Christ Jesus remains unshaken.
Like “Doubting Thomas,” I am simply asking for whatever clarity God may allow regarding the Shroud — not because I need it to believe in Jesus, but because I want Christians to know how to treat this artifact responsibly. My faith is already grounded in the testimony of Scripture, the witness of the apostles, the empty tomb, the birth of the church, and the ongoing work of the Holy Spirit. Dr. Jeremiah Johnston captures the posture I want to take when he says, “I believe based on the evidence, because I am not irrational.” That is exactly how I feel. I am seeking clarity about the Shroud so that, as followers of Jesus, we can either use it with integrity as historical and forensic evidence, or set it aside entirely if it proves not to be authentic.
If renewed research confirms that the Shroud truly belonged to Jesus of Nazareth, then it becomes one of the most powerful pieces of historical and forensic evidence demonstrating that He really lived, was crucified, died, and rose again.
Additionally, if the Shroud were ever confirmed beyond a reasonable doubt to be the actual burial cloth of Jesus, it would not only strengthen Christian faith but also directly challenge the claims made in Judaism and Islam regarding Jesus’ crucifixion and resurrection. This is why clarity matters. Christians should never misuse the Shroud, but neither should we ignore the possibility that it may be one of the most significant artifacts in human history.
However, if renewed research shows that it is not authentic, then we should have the integrity to omit it entirely from Christian apologetics and avoid using it as evidence for anything at all.
My faith in the truth claims of Jesus Christ does not depend on the Shroud. I believe He is exactly who He said He is because of what He said and did, as seen in the testimony of Scripture, the witness of the apostles, the empty tomb, the birth of the church, and the ongoing work of the Holy Spirit. Because of this, I can already say — with full conviction and integrity — “My Lord and my God.”
