Who We Are

Myra Adams, Russ Breault, David Adams & Mark Antonacci

The Sign From God Board of Directors are dedicated professionals who have spent decades studying, speaking, researching and writing about the Shroud of Turin. Now we have come together united in the belief that the Shroud of Turin should be utilized for evangelization to help bring a new generation to faith in Jesus Christ. 

On April 23, 2019, the Sign from God board, pictured, was at the Museum of the Bible for the kick-off event announcing the forthcoming exhibition about the Shroud of Turin. Russ Breault gave a presentation at the reception that was attended by the leadership of the Museum.

In conjunction with the forthcoming Shroud exhibition, on January 18, 2020 the Museum of the Bible hosted an all-star speakers event with five leading Shroud experts from around the globe. Russ Breault was the host of the sold-out, successful event called:

"Shroud of Turin: EXPLORE THE MYSTERY"

Myra at the National Prayer Breakfast in Washington D.C. February 2018

Myra is a writer and producer who has been keenly interested in the Shroud of Turin since 1997. She has seen the Shroud in Turin, Italy during its last two public exhibitions in 2010 and 2015. Myra was born and raised Jewish (maiden name Kahn) and came to faith in Christ in 1975. She believes that the Shroud is physical evidence left by God to show proof of Christ’s suffering and resurrection to those who need physical evidence in order to believe that Jesus Christ is the Jewish Messiah, King of Kings, Lord of Lords, and will come again.

Mark Antonacci
Chief Legal Counsel


Mark has proposed that a new series of sophisticated, minimally-invasive tests be performed on the Shroud at the atomic and molecular levels.

Mark Antonacci is an attorney and author who has studied all aspects of the Shroud of Turin for 37 years. He has been featured in newspapers, magazines, the internet, radio and television in the United States, Europe and South America.

Mark wrote The Resurrection of the Shroud in 2000, the most comprehensive book ever written on the Shroud until his landmark book, Test the Shroud was completed in 2015.

He gave the keynote address at the last international conference held in conjunction with the Shroud’s exhibition in 2010 in which he proposed that a new series of sophisticated, minimally-invasive tests be performed on the Shroud at the atomic and molecular levels of this famous burial cloth. Mark has written the leading scientific hypothesis that not only explains the Shroud’s unparalleled frontal and dorsal body images, but also its controversial radiocarbon dating, its excellent condition, its pristine human blood marks, their still-red coloration, the possible outer side imaging, coin features and flower images, skeletal features and all of Shroud’s other unique qualities.

This hypothesis has been published in a peer reviewed scientific journal, and although it involves a miraculous event consistent with the resurrection, its occurrence can be scientifically tested.  He asserts that these proposed tests could prove whether the Shroud was irradiated with particle radiation; whether the source was the length, width and depth of the crucified corpse in the cloth; when this event happened; where it occurred; the age of the Shroud and its blood; and the identity of the victim. Mark asserts this technology could also test all other natural or artistic explanations for the Shroud’s images or its radiocarbon dating.
