Shroud of Turin

We Request That Pope Francis Allow Sophisticated and Minimally-Invasive Scientific Testing to be Performed on theShroud of Turin.

Since 1978, thousands of scientific tests and experiments have been performed on this famous burial cloth and its samples. Significantly, only one of these results ― its medieval radiocarbon dating ― is inconsistent with the Shroud’s authenticity as Jesus’ burial garment. Examining the Shroud, its blood marks and other samples from the cloth at the molecular and atomic levels could prove that the radiocarbon dating attributed to the Shroud is inherently incorrect and that an unprecedented event happened to the dead man wrapped inside of this burial cloth.

We respectfully request that Pope Francis allow new tests on the Shroud of Turin. These tests would include the new technology summarized above and described in more detail in articles throughout the web site. These new tests would yield the most detailed information ever acquired from the cloth, while testing every explanation for the Shroud’s radiocarbon dating and image forming hypotheses that have been proposed.

  • Maryann Bartell As a lifelong Catholic, I would like to have the benefit of the additional tests so that we might know, once and for all, if the Shroud of Turin is truly the burial cloth of our Savior, Jesus Christ.
