Scientific Evidence for Miracles page 1: examination of the Lourdes rules for miracel acceptence.
It was never proven to be a forgery, and never proven to be authentic. There is no scientific method that can point the exact year, day hour and minute of the Shroud origin. The Church has
not announced it to be authentic (and never will, IMO). It is an icon of Holy Saturday. To miss that is to miss the point. The huge brouhaha that erupted was over an outdated C14 test that later proved to be false due to a bio layer of dust and pollen. The media doesn't cover what the book does. How anybody managed to make a forgery from 30' away with medieval equipment is anybody's guess. In my opinion, having studied the scientific findings at length, it is authentic. (amazon has a list) If you refuse to believe it, I couldn't care less.
No official statement has been made by the Church to my knowledge.
Why is it that when a miracle takes place, the scoffers and skeptics come out of the woodwork? Are they afraid to admit there is something greater than themselves?
My point is that virtually all Catholic miracles are like miracles from all other faith traditions. They are not scientifically substantiated and really do not need to be so because they are ultimately a matter for the believers and not for the skeptics such as myself.
The Shroud of Turin has been generally downplayed by the Catholic Church following the scientific investigation which did show it to be a forgery. You might want to read the book by Walter McCrone who performed the microscopic investigation.
As for Loreto, one rarely hears of it today. Certainly no modern scientific investigation has been conducted. There are a multitude of forensic investigations such as wood investigations that could easily confirm the original location of the building.
