Fascinating post about the Shroud of Turin

Fr. Dwight Longenecker has some interesting reflections about the Shroud of Turin and atheism.

After my visit I am more convinced than ever not only that the Shroud of Turin is the burial cloth of Christ, but that the mysterious image was produced by a blast of radiance from the resurrection. Those who wish to research the shroud can find scholarly and popular articles here and here. The most interesting thing about the shroud is the more scientific research is done the more the claims to authenticity accumulate. Not only is the image on the shroud that of a crucified man, but a particular crucified man.

He wore a crown of thorns. His legs were not broken. His face was punched. His side was pierced in a way consistent with a Roman spear. His back shows the marks of a severe flogging consistent with the flagellum used by the Romans. In other words, all the wounds match those not just of any crucified man, but those unique to Jesus of Nazareth.

Other details match in an extraordinary way. Fabric experts acknowledge that the particular linen cloth matches that used in the first century by wealthy individuals. The chemical traces on the cloth match the herbs and spices that were known to be used for Jewish burials in Roman times. Pollen from the shroud matches that present in Jerusalem in the first century. New scientific dating techniques counter the 1988 carbon 14 dating which identified a medieval date and they date the shroud to the first century.

Most mysterious is the image itself. In 1978 a team of American researchers were finally given access to the shroud. They ran a whole series of tests covering the range of scientific disciplines. Their analyses found no sign of artificial pigments and they concluded, “The Shroud image is that of a real human form of a scourged, crucified man. It is not the product of an artist.” What formed the image? The scientists were stumped and admitted that “no combination of physical, chemical, biological or medical circumstances” could adequately account for the image.

Paolo Di Lazzaro

So what formed the image? The best description is that it is an extremely delicate singe marking. Italian physicist Paolo Di Lazzaro concedes in an article for National Geographic that every scientific attempt to replicate it in a lab has failed. “Its precise hue is highly unusual, and the color’s penetration into the fabric is extremely thin, less than 0.7 micrometers (0.000028 inches), one-thirtieth the diameter of an individual fiber in a single 200-fiber linen thread.”

Di Lazzaro and his colleagues at Italy’s National Agency for New Technologies, Energy and Sustainable Economic Development (ENEA) experimented for five years, using modern excimer lasers to train short bursts of ultraviolet light on raw linen, in an effort to simulate the image’s coloration.

They came tantalizingly close to replicating the image’s distinctive color on a few square centimeters of fabric. However, they were unable to match all the physical and chemical characteristics of the shroud image, and reproducing a whole human figure was far beyond them. De Lazzaro explained that the ultraviolet light necessary to reproduce the image of the crucified man “exceeds the maximum power released by all ultraviolet light sources available today.” The time for such a burst would be shorter than one forty-billionth of a second, and the intensity of the ultra violet light would have to be around several billion watts.”

The scientists shrug and say the only explanation lies beyond the realm of twenty-first century technoscience. In other words, the extraordinary burst of ultra violet light is not only beyond the ability and technology of a medieval forger. It is beyond the ability and technology of the best twenty-first century scientists.

Consequently, I wrote an essay some time ago asking atheists who insist on “evidence for the existence of God” why they did not take time to study the Shroud of Turin. I suggested that if God did not exist, then the natural world had to be a closed system. If, however, just one miracle could be proven to have happened, then nature is not a closed system. If that miracle was intelligible then there had to be an intelligent force outside the system that was greater than the system. The resurrection of Jesus Christ would be that one necessary miracle. It is, after all, the miracle of miracles.
