The Church has acknowledged as true - only a choice few, to my knowledge. St. Francis of Assisi and St. Padre Pio being the two most famous.
There was also Brother Gino outside of Rome (don’t know if he’s still living). When waiting outside the building we would see him, my mother smelled something - and was wondering who would be selling perfume in that area. It was afterwards that we guessed it might - REPEAT MIGHT - have come from him - but I don’t know the Church’s stand on Brother Gino.
I will say I had the opportunity to attend a lecture in the U.S. about Padre Pio. Afterwards, all were invited to come and venerate a framed glove of Padre Pio’s. The room was tightly packed with people going to venerate. After kissing it, I remarked to my mother about the beautiful fragrance. She looked and said she hadn’t smelled anything. Amazed, I began to ask others - remember, tightly packed - we couldn’t move it was so crowded, so I couldn’t understand how people right next to me didn’t smell it, too. No one - no one had smelled it. One woman looked at me and just smiled realizing the grace that might have just been granted - for whatever the reason - as I continued in shock begging others.
Yes, most assuredly I believe the Stigmata exists in a very saintly few - we mustn’t jump lightly at every claim - just as Holy Mother the Church remains silent and reserves judgement on each case before making a declaration. But it exists.
