There is a shroud of Turin for one reason....... to increase the take in the offering plates
Uh, no. Geoffrey de Charney, the French knight who built the chapel in Lirey France where it was first put on display in ~1350, refused all pilgrims donation offered to support the church and the clergymen at the chapel, funding it instead from his familys own coffers. In fact that family funding continued even after his death to the point of bankrupting his family to the point his daughter Margaret wound up having to sell the Shroud to the royal family of Italy to survive.
Geoffrey De Charney was no ordinary knight. He was the Standard Bearer for the King of France who fought by the Kings side, his right hand man, considered above reproach in his piety and honesty. He is the author of the French Code of Chivalry for the Knights who served the King which was used for centuries. He is not one who would be party to a fraud. .
