Here's the first one:
A person who'd written a book on apparitions, visions and other miraculous things said that there was no way, no how that a "miracle" of any sort, healing included, that occurred in any context outside the Roman Catholic Church could be authentic. Here was his logic: Miracles occur, in part, to point people to the truth - to reveal the truth to them. Hence, any miracle that occurred in any tradition other than Roman Catholicism (although I assume he might include Orthodoxy within that, but he didn't say, so perhaps I shouldn't assume) must be inauthentic, for if it was authentic, it would mean that God was revealing truth through the means of that other tradition, and since those other traditions aren't the True Church, then God would be pointing people to untruths, or something less than the Full Truth so....such events must either be coincidental, natural or demonic - but no way from God.
