The pieces of the cloth that were cut from the ends of Shroud for the testing…
A single piece of cloth was cut from one corner. You know that, I’m sure. and I’m sure you think it’s pernickety to quibble about “ends” rather than “end”. However, details in these matters count.
… were in fact, pieces of fabric that were of medieval repairs on the Shroud.
No. This idea was the first proposed by Sue Bedford and Joe Marino, who obtained verification of sorts from some textile companies to whom they sent a photo of the Zurich sub-sample. On the basis of a single square centimetre, the companies suggested that the weave on one side of the ‘herringbone’ spine was more irregular than on the other, which could be evidence of different manufacture. Bedford and Marino used this idea to draw a picture of the radiocarbon sample, yellow (original) on one side and pink (medieval piece of fabric) on the other, to claim that each sub-sample contained a proportion of medieval to ancient fabric, sufficient to provide the dates claimed by the labs. This idea was quietly dropped (and replaced by another) when it was pointed out that the labs had cut their sub-samples up even further, so that the medieval/ancient ratio did not apply to some of them, and that ‘pieces of fabric’ have to be attached to each other in some way, which they had not considered at all.
The textile is much different…
No. Freers and July, in Arizona, and Donna Campbell, in Belfast, studied a fragment and some close-up photos of the radiocarbon sample respectively, and found that there was some loosening of the weave. This was almost certainly due to the process of cutting up such tiny pieces. Otherwise, the radiocarbon sample is indistinguishable from the rest of the Shroud. The latest version of the ‘patch hypothesis’ is that the Shroud was ‘invisibly mended’ precisely in order for it to be indistinguishable from the rest of the Shroud.
… and not of the same high quality of the herringbone weave of the type that was used during Jesus’s time.
Now you must have made this up. No “herringbone weave of the type that was used during Jesus’s time” exists. In fact there is very little cloth remaining from first century Israel at all (some from Massada and others from tombs) and none of it is high quality. Some authenticists have seen this as a real stumbling block, and speculated that the Shroud was imported from Europe. However, as I mentioned above, no 3/1 herringbone is known from there either.
The tests would indeed show a medieval age as that was when those particular repairs were carried out.
It is a truism to say that if the Shroud is medieval, a medieval date would result. Which it did.
