NOBODY worships the Shroud of Turin.
Why don’t you get back to me when you can answer my questions from #6.
First of all, Catholics do not "worship" the Shroud of Turin. If anything, it would be considered a relic.
Secondly, reverence of relics is based on Scripture. One of the most moving accounts of the veneration of relics is that of the very body of Christ itself. Rather than leaving his body on the cross, to be taken down and disposed of by the Romans (as was the customary practice), Joseph of Arimathea courageously interceded with Pilate for Christ’s body (Mark 15:43, John 19:38). He donated his own, newly hewn tomb as Christ’s resting place (Matt. 27:60). Nicodemus came and donated over a hundred pounds of spices to wrap inside Jesus’ grave clothes (John 19:39), that amount of spices being used only for the most honored dead. And after he was buried, the women went to reverently visit the tomb (Matt. 28:1) and to further anoint Christ’s body with spices even though it had already been sealed inside the tomb (Mark 16:1, Luke 24:1). These acts of reverence were more than just the usual courtesy shown to the remains of the dead; they were special respect shown to the body of a most holy man—in this case, the holiest man who has ever lived, for he was God Incarnate.
Keep in mind what the Church says about relics. It doesn’t say there is some magical power in them. There is nothing in the relic itself, whether a bone of the apostle Peter or water from Lourdes, that has any curative ability. The Church just says that relics may be the occasion of God’s miracles, and in this the Church follows Scripture.
The use of the bones of Elisha brought a dead man to life: "So Elisha died, and they buried him. Now bands of Moabites used to invade the land in the spring of the year. And as a man was being buried, lo, a marauding band was seen and the man was cast into the grave of Elisha; and as soon as the man touched the bones of Elisha, he revived, and stood on his feet" (2 Kgs. 13:20-21). This is an unequivocal biblical example of a miracle being performed by God through contact with the relics of a saint!
Similar are the cases of the woman cured of a hemorrhage by touching the hem of Christ’s cloak (Matt. 9:20-22) and the sick who were healed when Peter’s shadow passed over them (Acts 5:14-16). "And God did extraordinary miracles by the hands of Paul, so that handkerchiefs or aprons were carried away from his body to the sick, and diseases left them and the evil spirits came out of them" (Acts 19:11-12).
If these aren’t examples of the use of relics, what are? In the case of Elisha, a Lazarus-like return from the dead was brought about through the prophet’s bones. In the New Testament cases, physical things (the cloak, the shadow, handkerchiefs and aprons) were used to effect cures. There is a perfect congruity between present-day Catholic practice and ancient practice. If you reject all Catholic relics today as frauds, you should also reject these biblical accounts as frauds.
