Christian, you said:
"If you accept the possibility BXVI may not be the Pope you cannot accept him. This is comonly taught by thoelogians. A doubtful law is not law; a doubtful Pope is not Pope.
That is not correct. Some people believe that Pius XII was a doubtful Pope, so using your logic we must conclude that because Pius XII did some things that are questionable, he must not be a valid Pope. Heck, there were a few nutcases here who believed both Pius V and X were anti-popes. So should we assume that they aren't Popes since other people think they aren't?
And even though it's true that it will be the laypeople that help save the Church through the Grace of God, it doesn't mean that they should judge a still-reigning Pope.
Well a distinction has to be made here. One thing is to have a subjective doubt and other different thing is if it is objective.
My point is if you have a (subjective) positive and prudent doubt whether or not BXVI is the Pope, you can´t accept him, in the same way as you can´t say "well, maybe this is a sin but I do it anyway".
The fact that someone says "X is not Pope" is not enough for everybody to have that doubt. I may disagree (in fact I do disagree) with those who accuse Pius XII of heresy. I don´t even have the least doubt about his Papacy.
You see the difference?
One person here originally thought Pius XII was an anti-pope because of his decision to promote Bugnini or something like that. I don't think that qualifies as a heresy, though.
Neither I. That´s why I said the arguments which make you doubt have to be prudent and serious.
I see the difference, but what I'm saying is that just because you have a doubt about a Pope's Papacy does not mean you must say "The Pope isn't Pope, I have doubts about his Papacy so he must be an anti-pope!".
If you have positive, prudent doubt about a law then, in practice, is as if that law were null. Theologians say: "a morally doubtful obligation is an obligation subjectively null". If you doubt about someone´s papacy you may say whether "he was anti-pope" or "he ceased to be so by public heresy", what is certain is that you cannot follow a doubtful Pope.
Let me apply your logic in this sense. If someone has doubts that the Traditional Latin Mass is the True Rite of the Catholic Church, should they assume that because of those doubts the Novus Ordo must be the Rite of the Church? That does not apply as logical reasoning.
Yes, in conscience he must assume that, but you have to remember that we can have what is called a "wrong conscience" that is we may believe that we must do something when in fact we are not bound to do that, but if we believe we are bound and do not do that, then we sin, even if that action were not sin in itself. An example may clarify this:
Suppose it is Thursday but you believe it is Friday, and you know you cannot eat meat on Friday, but yet you eat meat, and then you realize it is Thursday. You cannot say "well I didn´t sin since it was not Friday" because you did sin in spite of your "wrong conscience", since as St. Paul says: "For all that is not of faith is sin." That is, as theologians explain, when we act against the dictates of our conscience we sin.
A bit complicated, right? :confused1:
