Common questions

Is Sister Caterina Capitani real or fake?
Miracles Jar's verdict is Silver: strong case, short of proof. Extraordinary if it happened as told — but the evidence can't fully confirm it. On the evidence, the record is some support.
Has Sister Caterina Capitani been debunked?
No. Extraordinary if it happened as told — but the evidence can't fully confirm it. The strongest natural alternative considered is spontaneous remission & the body's own recovery, but it does not fully account for the case.
What is the evidence for Sister Caterina Capitani?
Miracles Jar weighs 3 sources for this case. Points that support the claim: Terminal post-surgical external gastric fistula — after removal of most stomach, spleen, and pancreas — closed instantaneously; and Vatican medical commission found no scientific rationale for the recovery. Points that cut against it: Case is from 1966; original imaging and medical records are not publicly accessible and cannot be independently evaluated.
What is the natural explanation for Sister Caterina Capitani?
The leading natural account is spontaneous remission & the body's own recovery. Diseases sometimes resolve without treatment, or despite it. “Spontaneous” rarely means “no mechanism” — more often it means a mechanism we are only beginning to instrument. The full breakdown shows where that explanation holds — and where it stops.
When and where did Sister Caterina Capitani happen?
It is said to have occurred May 22, 1966 in Naples, Italy.
