If a pope would become a freemason, wouldn't this be heresy? Aren't heretics automatically ex-communicated?
I don't think so.
To give you an example: the Democratic Party. The Democratic Party has as its official platform that it endorses a woman the right to choose to abort her unborn child, which is against the teaching of the teaching of the Catholic Church. So the Democratic Party is in hersy. But does that mean that anyone who is a member of Democratic Party is automatically excommunicated by the Catholic Church. Of course not! A Democrat can be pro-life and be trying to change the Democratic party from within. But if he proclaims that a woman has the right to have an abortion, then he would be excommunicated.
So it is not enough that Pope John XXIII joined the freemasons. It must be showned that the Pope actually taught heresy.
But here is gets very dicey. If you can show me that the pope taught heresy, then I think we might as well be Protestants. The gates of death and hell did prevail against the Church. On second thought, I could not even be a Protestant. I could not see why I would still be a Christian. Christ would then be wrong! He promised that the gates of death and hell would not prevail, and that is exactly what happened!
Well, the reason that if someone who teaches heresy as a pope is a true pope, then the gates of hell would have prevailed, or similar.
He did not say that the gates of death and hell would not prevail against the pope, but against His Church founded upon Peter. Now, if the Church founded upon Peter is no longer the true Church, then that would mean to me that the gates of death and hell HAS prevailed against it.
They refer to statements talking about how heretics are automatically ex-communicated or similar.
Theoretically, yes. But unless the Church officially declares someone a heretic and ex-communicate him, I have no right to separate myself from him.
15 If another member of the church sins against you, go and point out the fault when the two of you are alone. If the member listens to you, you have regained that one. 16 But if you are not listened to, take one or two others along with you, so that every word may be confirmed by the evidence of two or three witnesses. 17 If the member refuses to listen to them, tell it to the church; and if the offender refuses to listen even to the church, let such a one be to you as a Gentile and a tax collector.
Mattew 18: 15-17
This passage has traditionally used against heresy. If someone preaches something that offends you, go to him privately. If he still does not listen, bring another. Then bring him before the church. Only then, if the church declares him wrong, can treat him as a tax collector.
This passage only makes sense if it is impossible for the pope himself to teach heresy. What then can you do. You cannot bring pope up before the Church, which is embodied in the pope! I doubt the pope would declare himself a heretic!
But this is the problem with the Sedevacantist. They do not have the authority to label anyone, let alone the pope, to be a heretic and excommunicate him from themselves. That can only be done by the Church. Now someone may be a heretic, but I have no right to declare that person as a heretic unless the Church has proclaimed him a heretic. Until the Church condemns I have no right to treat him as a vile tax collector. Instead, I am commanded to maintain the the bond of love with my brother in Christ.
Therefore I, the prisoner of the Lord, implore you to walk in a manner worthy of the calling with which you have been called, with all humility and gentleness, with patience, showing tolerance for one another in love, being diligent to preserve the unity of the Spirit in the bond of peace.
Ephesian4:1-3
I must be diligent to preserve the unity with every Catholic, which includes the pope, unless officially excommunicates. He may have done something that automatical excommunicates him. Actually, any mortal automatically excommunicates him. But Jesus said judge not, lest you be judge. I cannot judge who is automatically excomunicated unless the Church automatically excommunicates him.
The Sedevacantist is usurping the authority of the pope in order to excommunate a pope. How is that any different than what the Protestant Reformers did? They declared the pope to be invalid because he did not agree with their view of the gospel. Both Sedevacantist and the Protestant refuse to submit to the Church that was founded by Christ upon Peter.
18 And I tell you, you are Peter, and on this rock I will build my church, and the gates of Hades will not prevail against it. 19 I will give you the keys of the kingdom of heaven, and whatever you bind on earth will be bound in heaven, and whatever you loose on earth will be loosed in heaven.
Matthew 16:18-20
Jesus changed Simon's name to Peter. The word "Peter" means "Rock". So Jesus is says "You are Rock, and upon this Rock I build my Church". Unless the Church is built on the rock of Peter, it is not the true church. The Sedevacantist church is not a true church. It is just another Protestant church, but it deceptive because its practices are Catholic. Jesus said to Peter that whatever he binds on earth will be bound in heaven.
Also, do you believe that there have been "anti-popes"?
Sure. But the anti-popes were selected by sects that broke off from the Catholic Church. The Arian Church had its own pope, which from the Catholic perspective was an anti-pope.
Any successor of Peter cannot possibly be an anti-pope. Sedevacantists selected their own pope. But that pope is an anti-pope. Their pope lacks the succession to go all the way to Peter. He is only their pope because he agrees with them.
[dogma]
But if a pope declared the Latin mass to be the official mass, then how can another pope change this, since I thought declared dogma cannot contradict earlier dogma?

That is not matter of dogma, but of church discipline. The pope is only infallible in matters of dogma and morality. Dogma can never changed. You cannot have God being three persons on one day and have God being four persons in the future. You cannot have Mary being immaculately conceived one day and change it to Mary being a sinner in the future. Truth is unchanging.
Morality is tied to the character of God, so it also is unchanging. Abortion will always be immoral. Murder is always wrong, etc.
But church discpline can change. What are considered the holy days of obligation can change. For instance, the Church can saying that the Feast of the Assumption is no longer a holy day of obligation. Whether priest can be married can change. Peter had a mother-in-law, so he was probably married. I remeber reading that the first 1,000 years of the church priest could be married. But then the Church changed that. For the first three centuries, confess had to done publicly during Mass. But the Church in its wisdom realized that it prudent to change it to confessing your sins privately to a priest. It is used to be that you had to fast for three hous before communion. Now you only have to fast for an hour. And it used to be that you could meat on Fridays for the whole year round. Now it is only on Lent. So the Church has always changes the rules on matters of church discipline.
Think of when you were growing up. As you grew older, the parents changed the rules. When you were 5, may be the rule was he had to be in bed by 8:00. At 10 years old, maybe the rule was to be in bed by 10:30. Once you were of college age, they probably left it to you.
The Church established the Latin Mass to be used everywhere throughout the Roman Empire in the middle ages. That made sense, since Latin was the universal language. But things changed just as your bedtime rules changed as you grew older. Latin is no longer a universal language. What is more, starting at the 16th century, the Church started to be very agressive in its missionariy work to the Americas. There were many different languages that Catholics spoke. So eventually the Church decides it would be good to use whatever language the people spoke. I do not see anything wrong with that. The Holy Spirit leads in different situations at different times. If this were not true, then we all would be having Mass in Hebrew, because the first Mass was done in Hebrew. Then it was done in Greek. And then in Latin.
I can imagine the first time the people heard the Mass in Latin. I am sure that some hated it. They wanted to go back to the old Greek Mass. They may have even left the Church and started their own church, one that still gave Masses in Greek.
