Concerning the book "LA Popessa", do not take that as an authority on anything of Pope Pius XII as well as Mother Pascalina. It was put out by a pseudo-journalist. He just showed up one day in Rome in the early 80's, got the see Mother Pascalina for a relatively short meeting one day, than put out that trash in short order.
You can get the most direct commentary on that incident in Fr Charles Murr's "The Godmother: Madre Pascalina, a feminine tour de force", 2017. He knew her as a seminarian starting in the early 70's until her death. In this book, she clearly denounces "LaPopessa".
While Fr Murr is, yes a Novus Ordo ordained priest, in my reading him and hearing some of his interviews, he comes off as truthful, consistent and serious. I haven't seen any reason to doubt him.
While I know much will be revealed on the last day, the office of the papacy is the most solemn office. It is easy to look back on some things and say"I would have done it this way" and the like.
Just something to consider. The 3 hour fast. Had he not lessened the Midnight requirement, there probably early on have been some good priests as well as many of the faithful that would yes, maintain the Catholic Faith and carry on the by offering or assisting at Holy Mass, but the times would not be so late. 1pm was the traditional latest Mass time. So, no Masses after that. If a traditional priest has 2 or 3 Masses, he would have to start the last one by that time. Under the older law, he could not even take water until finished with his last Mass.
Related, in a way, and pertinent to what the Catholic faithful today also benefit from is Pope Pius XII permitting late afternoon/evening Masses, if the local bishop thought there would be benefit to the faithful.
By his holiness permitting this, possible qualms of conscience was effectively lifted from the tradional priests and faithful. While, yes, epikeia could be invoked, how much more solace to the average Catholic it would provide in these turbulent times.
That is why it is important to charitably correct anyone who might innocently conclude that we have late Masses because of Paul VI's "permission" in the mid-60's for so called Vigil Masses". He brought that out so they could meet there obligation for Sunday assistance at Mass be fulfilled by attendance at their Mass at 4pm or later on Saturday.
That is from the usurper Paul VI. It is totally different from what Pope Pius XII permitted with later in the day Masses.
Pope Pius XII-Saturday is Saturday. Sunday is Sunday.
Paul VI - Saturday late afternoon on is like Sunday.
I know many on the board recognize this.
I just wanted to offer this here.
