Did Christ wear a bag over his head when he was here?
I don’t quite follow your question and I don’t really care to. You silly person.
On the other hand, the Gospels provide no physical description of our Lord prior to resurrection ("no longer knowing him after the flesh" as Paul says -- no longer viewing him as that "James Taylor-like" illustration) while Revelation describes Him in great detail in His glorified state. So, in Kipling's words,we must "make allowance for their doubting too."
I appreciate your insightful comments and probably side with you more than not in this. To me, the shroud is authentic and was miraculously preserved. The only doubt that I previously had was concerning the head wrap -- resolved with info on the Sudarium. Looking at it from a very singular and Biblical point of view, it somewhat validates Christ's comments regarding the only sign that He would further provide the Jews was "the sign of Jonah" (reliable commentaries refer to this as the raising of the dead) (eg. Lazarus, the son of the widow of Nain, Jairus' daughter, and Christ Himself. Later, Peter raised Tabitha of Joppa extending use the sign of Jonah past our Lord's death). For me, the shroud is an on-going, extra-Biblical proof that the Jews (and other hardened souls would not believe even if someone were to rise from the dead. (Also refer to the parable of Lazarus and the rich man)
The attack about it becoming an object of veneration is no more forceful than the fact that the brass serpent on the pole, a valid and authentic instrument used by Moses, had afterwards been perverted into an idol, by infidels.
For Christians, it is important to note that the "testimony" of the shroud does more to buttress the Gospel accounts than undermine them.
