Having read all the responses, I still did not figure out the “why” though. I am not the original poster by the way. But I’d still be interested to know the answer to this.
It is obvious that the Vatican is going through a crisis right now, and losing a lot of popularity. It’s also obvious that most priests are not criminals (though most of the ones I’ve met seem to be), and that the current Pope, unlike his predecessor, is one of the most evil people alive. His Nazi background is only one of the many stains, which were also the reason why many Catholics were against his nomination in the first place.
So, looking at things from the Vatican’s point of view, which is obviously nothing more than a political one, there are two choices:
The first, and most logical one, is to ask for His Holiness’s resignation, making him the scapegoat for all that is evil in the Church itself, and move on, hopefully with someone better. (exactly what any country would do if the head of State was found guilty of similar crimes)
The second, to support the current Pope, whatever the cost, losing clout amongst believers and making fools of themselves.
My only guess as to why the Vatican has chosen the second course of action is that this would contradict a basic dogma, the infalibility of the Pope. Even if the Pope himself is found in bed with 200 deaf children, he’s only doing God’s will, and he has the right to do whatever he likes, because he is always right and the rest of us are always wrong. That’s what a dogma means, and once you start double-guessing this Pope and imply that he might be human (and therefore err), then the same could apply to all the ones to follow.
