What’s going on with the Catholic Church?
We live in a very confusing time in which the men claiming to validly occupy the Papal throne have not been teaching Catholicism, but instead have been teaching a new religion.
All Catholics are bound to obey a lawful, valid Pope in all matters pertaining to the discipline an governance of the Catholic Church, not only in matters pertaining to faith & morals. (Pastor Aeternus, Chapter 3- First Vatican Council). This makes it imperative that Catholics recognize the legitimate, valid Pope, and submit to his governance.
How can Catholics know who is the lawful, valid Pope, in order the he/she may submit to him?
We find the answer to this question in the infallible teaching of the Catholic Church. The Catholic Church teaches that she is the Spotless Bride of Christ and as such she cannot teach nor promulgate any form of error. The Catholic Church also teaches that the Pope cannot teach nor promulgate any form of error. This means that a lawful, valid Pope cannot promulgate teachings that contradict Catholic Doctrine.
The documents of Vatican II and subsequent teachings of the Conciliar/Synodal sect contradict Catholic Doctrines and Dogmas.
Therefore, every Catholic must ask himself/herself: Do the men claiming to be the Popes (who promulgated the documents of Vatican II and subsequent teachings and who are doing all they can to destroy the remnants of the Catholic Faith) actually possess Catholic authority?
What is a Sedevacantist anyway?
A Sedevacantist is mearly a Catholic who is professing Catholic Doctrine, as it has been handed down to us for over 2000 years. The Sedevacantist logically concludes that the Chair of Peter is vacant and has been vacant since the death of Pope Pius XII in 1958. He comes to this conclusion by looking at:
- The infallible teaching of the Catholic Church that the Catholic Church cannot teach error (cannot contradict previous Catholic Doctrine)
- The Catholic Church Doctrine that the Pope cannot teach error (cannot contradict previous Catholic Doctrine)
- Comparing the documents approved and promulgated at Vatican II with previous Catholic Doctrine
- The fact that all claimants to the Papacy from John XIII until today have promulaged doctrines that blatantly contradict Catholic Doctrine

“You are the ones who are happy; you who remain within the Church by your Faith, who hold firmly to the foundations of the Faith which has come down to you from Apostolic Tradition. And if an execrable jealousy has tried to shake it on a number of occasions, it has not succeeded. They are the ones who have broken away from it in the present crisis. No one, ever, will prevail against your Faith, beloved Brothers. And we believe that God will give us our churches back some day.”
– St. Athanasius
