Every miracle that leads to beatification or canonization of a saint is examined thoroughly by a commission of doctors and other scientists.
Also, an example: at Lourdes there is a
Medical Bureau, an official medical organization. Approximately 35 claims per year are brought to the attention of the Bureau.
Three to five each year are investigated more thoroughly - by examining the patient, the casenotes, and any test results (which can include biopsies, X-rays, CT scans, blood test results, and so on).
If this conference decides that further investigation is warranted, the case is referred to the International Lourdes Medical Committee, an international panel of about twenty experts in various medical disciplines and of different religious beliefs, which meets annually.
A full investigation requires that one of its members investigates every detail of the case in question, and immerses him/herself in the literature around that condition to ensure that up-to-date academic knowledge is applied to the decision. This investigator may also consult with other colleagues about the case.
For a cure to be recognised as medically inexplicable, certain facts require to be established:
- The original diagnosis must be verified and confirmed beyond doubt
-
Code:
The diagnosis must be regarded as "incurable" with current means (although ongoing treatments do not disqualify the cure)
-
Code:
The cure must happen in association with a visit to Lourdes, typically while in Lourdes or in the vicinity of the shrine itself (although drinking or bathing in the water are not required)
-
Code:
The cure must be immediate (rapid resolution of symptoms and signs of the illness)
-
Code:
The cure must be complete (with no residual impairment or deficit)
-
Code:
The cure must be permanent (with no recurrence)
CMIL is not entitled to pronounce a cure “miraculous”; this can only be done by the Church. If CMIL decides a cure is medically inexplicable, the case is referred to the Bishop of the diocese where the cured subject lives. It is he who, in consultation with his own experts and with the Vatican, makes the decision about whether a cure is “miraculous”.
Of over
7000 healings declared in Lourdes since the days of the apparitions, over
2000 have been delared inexplicable. Of these, the Catholic Church has acknowledged
68 as miraculous (the full list can be found
here , in Italian).
I believe even one such event should be more than enough, let alone over two thousand.
And we are speaking of only one place in the whole world.
These miracles happen daily all over the world, and they do not all involve a physical healing inexplicable according to science. A miracle may also be someone suddenly receiving a special and expensive medical treatment when there was no hope for salvation before, or someone receiving extraordinary peace and courage in the face of an incurable disease, thus dying in peace after having strengthened and consoled their loved ones.
