Very true!!
The point being made here is that others have been brought to God through this "piece of cloth", as you call it. This is not an item to worship, but rather a burial cloth that brings one into a closer relationship with Christ. It is one thing to say that Jesus suffered, died and is now risen. It is quite different to understand the level of suffering He endured for you and me. It is most humbling and excrutiatingly painful to consider the Lamb being subjected to torment and ridicule so that we would be saved. In this "piece of cloth" is ALL the evidence of what He endured for ALL OF US.
The Shroud has no mystical properties. It stands as witness to the Truth - that Jesus Christ died so that we may live.
Now that may not be true of you or me..but trust me people will flock expecting to see IT preform a miracle . Just like Moses pole..it will happen NYer
