What verifiable Church writers mention the item? Clement I? No. Origen? No. Tertullian? No. Augustine? No. Jerome? No. Aquinas? No...That gets you well into the 13th Century. If it existed before that, nobody seems to have known about it.

That fact that they did not mention the Shroud is not proof that it did not exist or even that they did not know of it. There were lots of things that existed in the world that they didn't discuss, probably because they were not in contention in their times. Absence of evidence is not evidence of absence.

Absence of evidence is not evidence of absence.

Yes, it is evidence of absence. Evidence is data that points you in one direction or another. There is zero data (evidence) that I am aware of for the existence of this item before the 14th Century. Zero data is zero data.

This explains much of Catholicism today.

NIV 1 Corinthians 4:6
Now, brothers, I have applied these things to myself and Apollos for your benefit, so that you may learn from us the meaning of the saying, "Do not go beyond what is written." Then you will not take pride in one man over against another.
