I understand what you are saying in regards to the older priests. I don't need documentation. I trust you. But, it is well documented in some many places that Padre Pio did not have any great love for the N.O. or Vatican II. I often wonder how he would have handled the future given those feelings and his strong obedience to the Church. At this point, it's anyone's guess, although I have read (this article?--can't remember) that one of his spiritual directees maintained strong support for the Traditional Mass and its priests up until her death in the 80's.
Padre Pio probably didn't have a lot of love for the NO. From what I've read, Fulton Sheen didn't either. Not a lot of us (on FR, anyway) do (because of the myriad of abuses of it). But Fulton Sheen (another obedient priest, I've read that Spellman put him through hell) said the NO Mass and did not try to supress it and keep the Tridentine.
Who knows? I just took a *bit* of offense at one of the first lines in the article -- "He never celebrated the Novus Ordo Missae." --- like what does that have to do with anything???
