There have been many Catholic critics of the doctrine of papal infallibility. In 1979 Father August Bernhard Hasler, Catholic priest, historian, and former staff member of the Vatican's Secretariat for Christian Unity, published How the Pope became Infallible: Pius IX and the Politics of Persuasion. His description largely matches that of Hans Küng but differs greatly from the official version of the Church. Since he used Vatican documents which still haven't been released to the public, we should seriously consider his charges:
Pius may have been insane. He suffered from seizures his entire life and later developed memory loss and an inability to think clearly for long periods of time (by his own admission). By 1869, disease and stress had taken a serious toll on his psychological state and people noticed that he had become unpredictable, irrational, emotional and dictatorial sometimes acting like a megalomaniac. Historian Ferdinand Gregorovius reported that 1870:
- The pope recently got the urge to try out his infallibility...While out on a walk he called to a paralytic: "Get up and walk." The poor devil gave it a try and collapsed, which put [the pope] very much out of sorts. The anecdote has already been mentioned in newspapers. I really believe he's insane.
Pius may have been dishonest. He never admitted to the things he had done in his efforts to have infallibility declared an official Church dogma. Cardinal Gustav von Hohenlohe told a friend: "In my entire life, I have never met a man who was less particular about the truth than Pius IX." Other bishops, like Bishop Henir Manret, openly called Pius IX a liar, so the charge was not at all unusual.
Pius stacked the council. There were 96 consulting positions, and among them 59 were filled by Italians (his biggest supporters) and just 37 to officials from other countries. Out of those last 37, a mere 6 had any proir experience working with the Vatican. Upon later reflection, many of the inexperienced members came to believe that their ill-fated appointments occurred only so that they could more easily be outmaneuvered by the pope's supporters. One, Bishop Joseph Karl Hefele wrote to a friend:
- The longer I stay here, the more clearly I see the duplicity behind my appointment as consultor concilii. That was just Rome's way of hoodwinking the public with the appearance of neutrality. In reality, I have no idea what I'm supposed to be doing here.
Pius had the council convened in Saint Peter's Basilica. What's wrong with that? Well, that place has some of the worst acoustics possible, making it incredibly difficult for anyone to actually hear what was going on, especially for the more elderly members. Bishop Hefele wrote: "I now sit right next to the Secretary's desk, in the immediate vicinity of the cardinals...but often I can't hear what is being said from the speaker's platform."
As bad as this situation was, the pope exacerbated it by refusing to allow any copies of the speeches to be printed, preventing the cardinals from actually taking the time to study them carefully. Moreover, small group discussions in which issues could be debated and collectively reviewed were expressly prohibited later, even large groups were banned.
Finally, only committee members were given permission to reply to a speech immediately after it had been given coincidentally, all committee members supported infallibility. All these rules were instituted by Pius before the council met and without consulting the bishops - at prior councils the bishops set their own rules for debate and discussion.
Pius drove the bishops mercilessly. The council was not permitted to postpone or recess under any circumstances, despite meeting in the harsh summer heat and in the middle of a malaria epidemic which caused a number of bishops to fall seriously ill. Upon learning of the spreading disease among the ranks of his bishops, Pius reportedly declared "Che crepino pure" (Let them croak).
