Ray Schneider responds very well to Charles Freeman as discussed in Scientific Study of the Shroud of Turin hampered by STURP? (But, of course, and expectedly, Yannick takes issue and Colin Berry has a point of view, all of which you should read at the above link.)
Ray writes what I mostly agree with:
Whatever the defects in Ian Wilson’s speculative account of the pre-history of the Shroud of Turin, it seems to me that
ChristopherCharles Freeman’s account is simply a tissue of debunking repeating many poorly substantiated claims about relics and then lampooning Wilson’s treatment.
He fails to mention explicitly the Gregory sermon or the chronicler Robert de Clari’s observation of an object that is described and sounds very like the shroud in 1204. He does note the location and claims that the identification of the Image of Edessa with this other relic which certainly sounds like the shroud can’t be. He doesn’t address Wilson’s speculation that on arrival in the city in 944 if was found to be a shroud and not just an image of the head of Jesus. Also it seems to me that the cloth of Oviedo (regardless of its Carbon date) has stains on it that have the same blood type as the blood on the shroud and have configurations that can be matched to the shroud which tends to corroborate Wilson’s conjecture that the shroud is authentic.
It is difficult to be certain of anything from all the fragmentary evidence, but simply pointing out in every case that perhaps there are other interpretations or that Freeman doesn’t see Wilson’s point is not really an argument but a preconceived conviction. If Wilson can be convicted of being prejudiced in favor of shroud authenticity it seems to me that Freeman can be convicted of the opposite prejudice. One agenda driven account is not more convincing than another. Wilson never claims to prove the shroud authentic. He is making a fragmentary case with what evidence there is.
The shroud is a very mysterious object with remarkable and wholly unique properties and unless we can convincingly explain it then the possibility of authenticity cannot be simply ruled out. There are many small things that point to authenticity and there are some that point in the opposite direction.
I do think that Freeman has a point about the handling of shroud research. STURP did what it could but it was a quickly thrown together association of scientists with relatively few resources. If they were not as professional as they might have been it should be remembered that they were the first and only investigation that has taken place and their research was compressed into 120 continuous hours. These are hardly ideal circumstances. Freeman’s criticisms are Monday morning quarterbacking from the armchair position.
