This is snake oil that should not be associated with Christianity.
This sort of object idolatry is pretty common in pagan religions, such as fragments of Buddha’s tooth or the like.
A joke by Dr. Martin Luther:
“A German, making his confession to a priest at Rome, promised, on oath, to keep secret whatsoever the priest should impart unto him, until he reached home; whereupon the priest gave him a leg of the ass on which Christ rode into Jerusalem, very neatly bound up in silk, and said: This is the holy relic on which the Lord Christ corporally did sit, with his sacred legs touching this ass’s leg. Then was the German wondrous glad, and carried the said holy relic with him into Germany. When he got to the borders, he bragged of his holy relic in the presence of four others, his comrades, when, lo! it turned out that each of them had likewise received from the same priest a leg, after promising the same secrecy. Thereupon, all exclaimed, with great wonder: Lord! had that ass five legs?”
And after we dispose of the frauds like the ossuary and the shroud, we can dispose of the frauds like the Gospel of Luke.
