there are a number of things that can be done to speed up the process such as treating the shroud with reducing sugars (which evidence suggests it was), having the presence of proteins (which could be provided by the body itself), removing water (easy enough to do in a dry desert environment), increase temperature or pH.
Well, this theory is nice as a theory. Treating with reducing sugars is a necessary element for Maillard reaction to ever occur, as far as I can understand. Presence of proteins (bio-catalysts I assume) requires additional fluids and goes contrary to removing water and the fact that there's no damage on the shroud. You might, however, make an experiment to reproduce such effects. Take a recently dead body, wrap it in a premade shroud of like technology, put it in a tomb (there are still existing tombs there in Palestine), close it with a stone, wait 30-40 hours then remove the shroud (and bury the body, for the good). Then put the shroud in a wooden case for a year (I don't think more is required) and see if there will be traces of an image of a body. Document your evidence, including the comparison in possible strength of an image on the Shroud of Turin to what will happen to yours, and present these results to the community.
Why does it have to be a special thing? For all we know some guy did something worse than normal and they got creative in punishment.
Hmm, yes, my bad, however historians disagree on the commonness of nailing vs tying while performing a crucifixion. But, there is another nitpick about the man on the Shroud - he was buried, and buried according to Jewish tradition, while normally crucified persons were forbidden to be buried, like those 6000 jews crucified in the 0060s. So this alone is unusual to a significant degree.
True it doesn't provide evidence for any of the miraculous claims in the Bible. If it was shown to definitively Jesus's it would only provide evidence for a historical Jesus. Which while I still have my doubts is quite possible to have existed.
Hey, you claimed that the Bible is a historical book, and now you doubt of its historic part being true?! This is inconsistent.
Deal. Let homosexuals marry, stop harrying people for having abortions, get out of the way of stem cell research, stop letting priests molest children and don't incite hatred against other religious groups and i'm sure everyone here would be happy to let you live in happy fun time land.
We are bound to defend life and love in all forms, and we are bound to attempt to give you understanding that abortion is killing children, embryonal stem cells research that leads to destruction of embryos is killing children (the Church has no objection if you get spem cells from adults or from what remains after a child was born and what is normally no longer needed, umbilical cord, placenta and the like, that has fulfilled its function and is now thrown away), homo marrying is fornication in its utmost, molesting children is fornication again, and inciting hatred is not the way it should be (yes, we must stop hating others indeed). Yes, "leave us believe in what we want to believe" is a wrong move from our side, probably it's the main reason of why am I still in this discussion.
as Christians, you believe that morality originates from God, no??
Therefore, you believe that no virtues exist without God...
This "therefore" is non sequitur. You're stating "God -> morality" and concluding "~God -> ~morality".
Do you believe that abortion should be illegal and why?
Because we believe (and this was revealed to us several times) that a child receives a soul at the moment of his conception, so whenever a zygote or an embryo dies, it's the end of that child's life. We also know that baptizing is "second birth" to the Holy Spirit, so all past sins including Adam's sin are forgotten, so if a person couldn't commit sin but was baptized and died, he will be saved and will go straight to Heaven. But we are not sure about the fate of souls that die prior to being baptized, such as souls that die in their mother's womb, regardless of reason. We don't know if a child is given a too short life by God or by men, if a spontaneous abortion happens, but we know that if an abortion was intended, it's a mortal sin, and all who are involved participate in the guilt for it. We also know that evil done by one is somehow spread onto others, sometimes making others choose to sin again, and thus spread evil further. One of the examples is this:
"You are in a subway, you are in a hurry and you force your way through the crowd. You have hit a person on your way and did not apologize. That person appeared to be a cardiac surgeon thhat was also going to work, and he was not able to suppress the emotions that arise from your actions prior to making a critical operation, thus his patient died. This patient appeared to be a brother to a bus driver who, when informed of his death, failed to withstand the grief, but was already driving a bus full of people, so he got in a traffic accident resulting in more deaths and injuries. So your hitting caused numerous deaths, some guilt of them dying is also on your shoulders, even if you don't know this."
