I wouldn’t simply discount them, I’d just question them and I’d be more inclined to believe the ones that have been modernly tested.
You do realize that Catholics are not required to believe in these miracle or any apparitions, right?
We have a house near Knock Ireland, where Our Lady appeared in 1879.
The villagers who saw her, along with St. John the Evangelist and St. Joseph were grilled practically their entire lives, separately and by many people. Their stories never waivered, they never offered details contrary to each other, and they held firm with what they experienced and saw.
The Church determined that they were not deceiving people. Indeed, you’d have to be looney to make something like that up. St. Bernadette was pretty much tormented for years for saying she saw a Lady who claimed to be the “Immaculate Conception”.
She was offered all kinds of thing on behalf of her poor family fi she would admit to making the whole thing up, She wasn’t lying, and finally the local Bishop understood.
It was a genuine apparition. The Church has nothing to gain by advancing things that are sketchy. The Church herself is the first one to try to discredit seers, visionaries, and miraculous occurrences.
The scientific “proofs” add important details for many, but all through history there have been miracle that were accepted due to the extraordinary investigations of the Church herself.
peace.
