The Shroud of Turin has captivated the imagination and challenged the intellects of scientists and historians ever since the first photos were made of it in 1898. It gives us a glimpse into the suffering of Our Savior; its revelations to the many branches of science give us physical proofs of the transcendent; it is an ancient miracle which can be analyzed and documented, if not completely understood, by the most modern of scientific methods; it is a reproach to an age of atheistic skepticism and secular humanism. Surely it beckons to the Catholic Home-School for study. Unlocking the Secrets of the Shroud is a medical doctor's study which "looks at the Shroud through the eyes of a first-century Jew." The Shroud thus becomes a link between the Old and New Testaments. Not Made by Human Hands studies not only the Holy Shroud but also the miraculous image of Our Lady of Guadalupe. It is written by a scientist/religious to prove the authenticity of both images.
