During his short ministry, he miraculously saved and healed many. These acts instantly converted many. The Shroud is one of these unexplained miracles. It was not meant for people like yourself who enjoy a perfect faith in Jesus.
You assume the signs left for the doubting Thomas types aren’t actually distractions that will lead to their 2nd death. I try to not make assumptions because I’m imposing my will on God.
Is it real? Dunno. Therefore I put no faith in it.
Also, by no means is my faith perfect. Not even close.
There was a guest on the old Art Bell radio program who became a Christian because of the shroud.
