Very common to fake stuff about Jesus starting around 100 AD or so. If you had an artifact, (fake or real) then it brought more parishioners to your church which always meant more money.
Your flat denial is foolishness until you can duplicate the evidence using 12th or 13th century technology.
You are ignoring the historic facts about the known first modern appearance of the Shroud in Lirey, France. It appeared in the possession of a Geoffrey de Charney, who, on his own dime, built a chapel to house it, used his own family's wealth to endow that chapel and refused to accept any donations from pilgrims at all. Geoffrey was the Standard Bearer of the King of France, the author of the first code of Chivalry for all knights, and was considered above reproach. He, in fact, almost bankrupted his family supporting that chapel. As a result, his widow wound up selling the Shroud to the Royal Family of Italy after his death. So your argument fails on several levels.
Add to this, Geoffrey's Great Great Grandfather Geoffroy de Charny (spelling was a matter of opinion back then) was the second in command of she IV Crusade and was present and heavily involved when the Hagia Sophia was looted by the Crusaders and Constantinople was sacked. Among the relics listed in the Hagia Sophia was the Shroud of Christ. . . it disappeared in the looting along with many other holy relics and objects of veneration into the hands of the crusaders. De Charny was later burned at the stake along along side Jacques de Molay, leader of the Knights Templar, in Paris.
Money did have something to do with the draft letter found in the archives of the Bishop of Trois, apparently being prepared to be sent to the Antipope in Avignon, France, complaining about the exhibition of the Shroud drawing pilgrims to the Chapel in Lirey, a letter which apparently was never sent as no companion letter was ever shown to have been received in the archives in Avignon or in the archives in Rome, nor a finished copy of the draft letter in Trois.
Which would you, as a pilgrim rather go see, the Purported Shroud of Jesus over in Lirey, or the bones of one of the hundreds of various saints in the Cathedral in Trois. . . especially If you were expected to drop money in the poor box to get a glimpse of another ho-hum saint's toe bones. . . and it was said you could see Jesus burial cloth without making a donation??? The Bishop was miffed they were bypassing his Cathedral's relic collection (and collection plate) and going to Lirey.
You solved it, man.
Let me guess...
You haven’t done much honest research on the Shroud....
