Because of the mental retardation and mind rot that is dogmatic sedevacantism, I find myself having to explain things yet again.
You obligation is to first and foremost keep the faith.
You do what Catholics have always done. When something appears to not be Catholic you stay away. Not making judgements about the personal salvation of that person and not making judgments about high theological matters such as the depostion of a Pope.
you just stay away. That is all God asks us to do.
He does not ask us to "Go forth and convert on the internet everyone to sedevacantism!". He does not say "you are the greatest person ever for figuring out that the Pope is not the Pope!".
Folks, get a grip. Really.
1. Yes, your first obligation is to keep the faith.
2. Next, you follow St. Paul's instruction to Titus. Avoid heretics. This will help you keep the faith. But if you think a heretic is the leader of the Catholic Church, the Vicar of Christ, then you are putting your soul in jeopardy and scandalizing the weak-minded.
3. If a heretic cannot be a Catholic and if we are to avoid him (Titus), then he is certainly not "the Holy Father." But if you insist on calling him "the Holy Father" then you are not following what St. Paul said to Titus and you may very well lose your faith from your stubbornness.
4. And, God certainly does not ONLY ask us to "stay away." We are called to be "martyrs." Martyrs testify to the truth and help their brothers and sisters understand the spiritual danger surrounding them. This is called charity.
