A newly published scientific study has offered compelling support for the Gospel account of Christ’s burial, reinforcing long-held Catholic tradition surrounding the Shroud of Turin.
The Shroud—believed by millions of Christians to be the burial cloth of Jesus—contains faint yet distinct bloodstains and the image of a crucified man. Now, groundbreaking research by immunologist Dr. Kelly Kearse, trained at Johns Hopkins University, reveals that these stains most likely came from an unwashed body—just as the Gospels and Jewish burial customs describe.
“Forensic evidence supports the idea that the blood on the Shroud came from fresh wounds, not a washed corpse,” Dr. Kearse explained in his peer-reviewed study, Blood Transfer to the Shroud of Turin: The Washing Hypothesis Revisited.
In his experiments, Dr. Kearse recreated post-mortem blood conditions—reduced clotting and increased acidity—and tested how blood would transfer to cloth under such conditions. Under ultraviolet light, he observed the appearance (or absence) of serum halos, the clear rings that form around clotted blood.
These halos are visible on multiple wounds on the Shroud and only form when blood has already begun to clot before contact with fabric. “Their presence confirms that the blood came from fresh, unwashed wounds,” Kearse wrote, “consistent with traditional Jewish burial practices, which forbid washing the bodies of those who die violently.”
This directly contradicts earlier claims, such as those made by Dr. Frederick Zugibe in the 1990s, who suggested Christ’s body was washed before being placed in the tomb—a theory based not on Scripture, but on the non-canonical Gospel of Peter.
Catholics may recall that the canonical Gospels mention Joseph of Arimathea wrapping Jesus’ body in a linen cloth with spices, but make no mention of washing. In fact, ancient Jewish law required that blood lost during trauma remain with the body for burial.
Dr. Kearse’s study also considered natural methods for how the blood transferred so clearly to the linen. His research showed that dried blood on a body could become rehydrated in the humid conditions of a rock tomb, allowing it to adhere to the cloth without smearing. In an earlier study, he confirmed that “high humidity alone is sufficient to re-moisten dried blood and allow transfer to linen,” further affirming the plausibility of the Gospel account.
The Shroud of Turin measures approximately 14 feet by 3.5 feet and bears the full-body image of a man who was scourged, crowned with thorns, crucified, and pierced in the side. It has been revered by saints, studied by scientists, and shown to the public on rare occasions. Though radiocarbon dating in the 1980s suggested a medieval origin, many scholars now question those results due to contamination and methodological flaws.
While Dr. Kearse’s findings do not conclusively prove the Shroud’s authenticity, they offer powerful evidence supporting its consistency with the passion, death, and burial of Jesus Christ. “No known process can account for the precise blood patterns on the Shroud if the body had been washed,” he concluded.
The Catholic Church has never formally declared the Shroud to be the authentic burial cloth of Christ, but has long encouraged veneration of it as an icon that brings believers closer to the mystery of the Passion. Pope John Paul II called the Shroud a “mirror of the Gospel” and Pope Benedict XVI described it as an “icon written in blood.”
For many faithful Catholics, the latest research offers not only scientific insight—but renewed spiritual consolation. The image on the Shroud continues to testify, not just to the suffering of Christ, but to the truth of His death, burial, and Resurrection.
