Mounting evidence for the Shroud of Turin’s authenticity

Updated: Jul 12

On Easter Sunday, one of the possible Gospel readings described how Peter and John found the empty tomb. It also described the first sight of Jesus’ burial shroud:

“So Peter went out with the other disciple, and they were going toward the tomb. Both of them were running together, but the other disciple outran Peter and reached the tomb first. And stooping to look in, he saw the linen cloths lying there, but he did not go in. Then Simon Peter came, following him, and went into the tomb. He saw the linen cloths lying there, and the face cloth, which had been on Jesus’ head, not lying with the linen cloths but folded up in a place by itself. Then the other disciple, who had reached the tomb first, also went in, and he saw and believed” (John 20:3-8).

The cloths must have been amazing if they caused John to believe in the Resurrection!

Many Catholics have held the Shroud of Turin to be the main linen burial cloth discovered by the disciples in the tomb. Then the Shroud was carbon dated in 1988 by three different labs. The test showed the linen to date from 1260–1390 AD, seeming to prove the Shroud a medieval fake! Since then, however, researchers have uncovered overwhelming evidence pointing to the Shroud’s authenticity.

Colorado is home to the Turin Shroud Research Center in Colorado Springs, which is leading the way in compiling the mounting evidence. The Center, under the direction of the physicist Dr. John Jackson, has been researching the Shroud for 50 years, including as part of the study in 1978, STURP, which had unique access to the Shroud. A recently updated book by Dr. Jackson, The Shroud of Turin: A Critical Summary of Observations, Data, and Hypotheses (CMJ Marian Publishers, 2017, or online with limited images) provides an overview of where research on the Shroud stands today.

Here is a brief summary of some major points pointing to the Shroud’s authenticity:

1. Its History

We now know enough about the shroud’s history to show it predates the 14th century.

Historical accounts follow a miraculous full body image of the Shroud from Antioch, to the region of Cilicia (in modern day Turkey) to Constantinople, where it was kept hidden by the Byzantine Emperors for centuries. It was publicly displayed in Constantinople shortly before the Crusaders arrived and it seems that one of the leading Crusaders brought it back to France, where it remained privately until its first public display in Lirey, France in the 1350s. After suffering from fire, it was entrusted to the royal family of Savoy, who brought it to its current location in Turin, Italy (see pages 7-43).

2. Its Material and What’s Attached to It

No medieval examples of the herringbone stitch used to make the Shroud’s linen have been uncovered, though there are ancient matches from the Near East. Even more intriguing is the dirt found on the Shroud (especially surrounded the nose, knees, and feet), which match dirt and stone found in other tombs in and near Jerusalem. Likewise, pollen from plants of the Jerusalem area blooming in March and April has been discovered, along with pollen matching the historical record of the Shroud in Turkey, France, and Italy.

3. How the Image Was Made

Dr. Jackson lists a number of theories, including one which he proposed, for how the Shroud’s image was imprinted. We do know, however, that it was not painted, as the image rests only the very top of the linen threads and no paint materials soaked into the threads. It was discovered in the late 1800s that the Shroud has the qualities of a photographic negative, which is why a negative of it produces a clearer image. The image also has three dimensional qualities. Some current theories point toward radiation or an electric field as responsible for producing the image. See Dr. Jackson’s “Radiation Fall-Through Hypothesis, and Antonacci’s revision, on page 83.

4. The Image Itself

The Shroud contains real blood (both pre- and postmortem), which has recently been shown to be from a torture victim. It is faithful to Jewish burial practices, as well as the Roman method of Crucifixion. As such, it does not match medieval imagery of the crucifixion, which portray nails in Jesus’ hands and feet, but rather in the wrist and ankles in accord with archeological evidence of Roman crucifixion.

5. It Matches Another Ancient Image of the Passion

The Shroud matches blood stains from the Sudarium of Oviedo, the head cloth used to cover Jesus after the crucifixion and in burial. There is documentation that it was brought to Spain after the Persian invasion of Syria in the seventh century. When the two cloths are compared, the blood stains match up identically.

So what about the carbon dating? Dr. Jackson offers a number of reasons why the test pointed to the Middle Ages. He notes that his research group, STURP, made recommendations to take samples from multiple locations and to clear them of contaminants. It was also suggested to avoid the area that was chosen for the carbon dating samples as it was already shown to have some inconsistencies with other locations, such as a greater presence of cotton. None of these suggestions were followed! An alternative dating method, fiber tensile-strength comparisons, conducted in 2015, pointed to 372AD, plus or minus 400 years (93).

The Shroud provides an incredible access point to learn more about our Lord’s Passion, burial, and Resurrection. It has an amazing history, made only more intriguing by new scientific methods. Dr. Jackson’s book provides a helpful, introductory summary. He and his wife (Rebecca) also speak on the Shroud across the world and the Turin Shroud Center of Colorado hosts an exhibit at St. Gabriel’s Church in Colorado Springs, including a full-size replica of the Shroud.

It is also gives us a unique glimpse at the likely appearance of Jesus. As such, it prompts our prayers: “Restore us, O God; let thy face shine, that we may be saved!” (Psalm 80:3).
