I will respond to this, but then I have to go to bed as it is late here on the East coast. Once again, I do not believe in using labels to describe people, as they are simply divisive. The Second Vatican Council is a valid Ecumenical Council; if it is rejected, or done away with, or “dealt” with, then there is nothing stopping anyone from doing the samething to any other Council.
It is true that there have been anti-popes in the past, but it is still a slanderous accusation to claim that any of our Popes since the Council are filled with errors in any way, as they have said and done nothing contradictory to Holy Tradition and Sacred Scripture. We can go in circles like this indefinitely, and perhaps we should simply agree to disagree, but an individual, or a group such as SSPX are in no position to accuse any Pope of being “infected” with modernism or errors, or bad theology, as the authority to do so was never granted to them by Christ. The SSPX is not itself the Church. If it is part of the Church, then it should act as part of the Church. But the group itself tends to condemn Popes, while claiming loyalty to the Bishop of Rome, and therefore assumes a power for itself that it does not have the right to.
As for the Third Secret, it is only speculation by a group that the entire secret was not revealed
en.wikipedia.org/wiki/Third_Secret_of_Fatima#Third_secret. The Vatican has stated that the whole secret has been revealed. Not believing them is simply conspiracy theory, and a lack of trust. The fact of the matter is this: if the third secret were not revealed in full, then any rumor that it is about the Second Vatican Council can immediately be called into question as the people who started these rumors would most likely not been in a position to know the secret before the year 2000 anyway. We cannot allow ourselves to be reduced to doubting the Church. That is a tool of the devil, to try and get us to think we’re being lied to and kept from a hidden secret. That is what I meant by gnostic.
We have been promised always to have the leadership of the Pope, but it is not up to us as individuals, or in any group to claim the right to label a Pope as heterodox in anyway. We simply do not have the authority or the power to do so. That is the real issue here: who has the right to criticize the Pope, if the Pope is the Supreme Pontiff? I would start with the hierarchy of the Church, herself, such as future Popes, Councils, etc. But to assume that each Pope since the Council is a bad Pope shows a lack of faith and trust in the Spirit, as it is the Holy Spirit that guides the Church, and the Pope, and it shows that you claim the wisdom to do so. But Padre Pio did not seem to see anything wrong with Pope John Paul II.
