Had medieval con men been able to fake our Lord’s burial shroud, they would have faked as many as possible. There was no mass communication in the Middle Ages, a faker would have been trying to sell shrouds in not only Turin, but every major city in Europe.
There is also the fact that the image on the Shroud is nearly identical to the image on the Veil of Veronica which had a chapel named for it in the 8th century.
“Had medieval con men been able to fake our Lord’s burial shroud, they would have faked as many as possible.”
Correct. And they did. Indeed, look at my post from the Roman Catholic Encyclopedia. The innumerous fake “true burial clothes” is one of the reasons the RCC gives for doubting the authenticity of the “relic.”
