The shared claim
An image, icon, or statue produced or took in a substance — tears, blood, oil, myrrh, milk — or moved or bore a mark said to have no natural source.
One claim, many sanctuaries
Across the Christian East and West — and, in its own idiom, far beyond them — the same wonder recurs: an image weeps, bleeds, exudes oil or myrrh, carries an impression no hand is said to have made, or, in the Hindu milk miracle that swept the world in 1995, a statue appears to drink the milk held up to it. The figure honored changes with the tradition; the shape of the report does not.
Because the claim is physical, it is the most testable kind we hold. A substance is either being produced or taken in, or it is not, and what is involved can be sampled, matched, and measured. That is why this shelf holds both the catalog's clearest frauds and a few of its genuinely open cases.
The same questions, the same rivals
Wherever the claim appears, the natural rivals are nearly identical: condensation and capillary wicking, surface tension drawing liquid onto stone (the leading account of the 1995 milk miracle), applied oils, pigment or pigmented bacteria such as Serratia marcescens, fungus from handling, and outright forgery. Where nothing is produced at all and the wonder is a face seen in a surface, the rivals shift to pareidolia and the drift of a story in the retelling.
None of these is specific to a religion. The chemistry of a hoax in one tradition is the chemistry of a hoax in another, which is exactly why comparing them is fair rather than rude.
Where they part ways
What separates a Civitavecchia — where the 'blood' was DNA-matched to a member of the household — from a case that stays open is not the tradition it belongs to. It is the documentation: who examined the object, under what controls, and with what result. Lined up together, the proven frauds and the genuinely unexplained sit on the same shelf, and the difference between them is the evidence, not the creed.
