Actually, medical miracles of this sort have to be certified by a panel of doctors (and they're not all Catholic doctors, either) who examine the evidence independently and ascertain that there was no humanly explicable or natural explanation for the manner of healing. Because of its suddenness, completeness, and permanence (no relapses)it has to be a recovery which would NOT be accounted for by the drugs or procedures or other therapeutic attempts.
I love it when God shows his power and His favor for those who trust in Him, in this way.
"Beloved, pray for us." (1 Thessalonians 5:25)
“and ascertain that there was no humanly explicable or natural explanation for the manner of healing.”
This happens even when no one prays to a saint.
Nor does healing mean that dear Teresa heard, had the ability to answer, nor did so.
It is an assumption without foundation.
Christmastime blessings to you.
