well, if his infallible statements are from the Holy Spirit, then he according to the council, does not need to consult anyone.
Well, saying his statements are
from the Holy Spirit is rather different from saying that they are
protected by the Holy Spirit. All that Catholic teaching implies is that the Holy Spirit will not allow a falsehood to be definitively taught to the universal Church, whether by universal ordinary teaching, a council, or an
ex cathedra statement by the Pope. It does not imply that any definitive statement made is directly from the Holy Spirit, as though the Pope has a line to God that he can call to figure out what to say.
But more to your actual point - actually, those who explained the meaning of the definition of papal infallibility when it was proposed to the Vatican I council specifically said that the definition does not mean to imply that the Pope need not consult his brother bishops, scripture, etc.
I suppose it depends on what you mean by asking whether he *needs* to do so or not. If we are talking simply about the requirements to "ensure" that an
ex cathedra definition will be infallible, then you are correct, he does not need to consult others. In theory, I think, it's possible for a Pope to make an
ex cathedra proclamation even if he has not consulted, done the research, etc. If the proclamation he would make in such a case would be true, then the Holy Spirit would have no need (as far as infallibility is concerned) to prevent it from being proclaimed.
On the other hand, if we are talking about what the Pope needs to do as a matter of
practical and moral necessity, then, yes, he may need to consult with others if he wishes to come to a conclusion about what is true. If he doesn't, he may happen to get right, of course - or, of course, if he were to come to a false conclusion, the Holy Spirit (in whatever way He works) would prevent this from ever being proclaimed.
it does not matter if 100% of the church opposes what he says.
I'm not sure this is really correct. I may be wrong, but I don't think universal defection from the truth is possible in Catholic thought - nothing about Catholic teaching on papal infallibility implies that it is. In other words, it would never be possible for the Pope to define something which 100% of the Church opposed, since such a thing would be false.
Again, the Church's teaching simply means that the Holy Spirit will never allow the definitive teaching of His Church to be in error.
and from my understanding, it is when he sits upon the throne of St Peter and speaks ex cathedra concerning doctrine and morals.
His proclamations are protected from error when, exercising his office of universal teacher, he teaches to the whole Church definitively on a matter of faith or morals.
Sorry, I am not trying to argue for the Catholic position (which I am not even sure I accept anymore) - only explaining it. I did intend to discuss the councils, and wish to get back to that as well.
