Here is what I had written about Boniface VIII. I wrote this an awfully long time ago, so it could probably be tidied up. I did tidy it up a little, but I’m tremendously exhausted right now so who knows how it ended up. Note that I was only focusing on Protestants when I wrote this, but I could change it around to fit any non-Catholic.
I wrote it in reference to Boniface’s statement: “Furthermore, we declare, we proclaim, we define that it is absolutely necessary for salvation that every human creature be subject to the Roman Pontiff.” If you were referring to something else, sorry, my bad.
The Church teaches the following:
- There is no salvation outside the Catholic Church - various places
- It is necessary to be subject to the Roman Pontiff for salvation - Unam Sanctum
- Protestants can be saved because though it is imperfect, they do have a communion with the Catholic Church - various places
There is no contradiction amongst these.
The question that seems to be raised is, how can Protestants be saved if they are not subject to the Roman Pontiff? The answer is they can’t. There is something very important to note here.
The Roman Pontiff is the leader of the Catholic Church. By definition, all those who are in the Catholic Church are subject to the Roman Pontiff, just like all those who are citizens of England are subject to the Queen, even if for some reason they never become aware that they are in fact her subjects or even mistakenly think they are not. Remember - there is one baptism, which baptizes people into one body of Christ, and that one body of Christ is the Catholic Church, which is subject to the Roman Pontiff. Any person who has been baptized is a member of the body of Christ and by the very fact that he is, is subject to the Roman Pontiff, even if he doesn’t know it. A 3 year old baptized Catholic is a member of the body of Christ even though he has no idea he is subject to the Roman Pontiff.
Now people can either stay in the body of Christ or leave it, and once they have left it they can return. They leave the body by committing mortal sin, and they return by repentance. Mortal sin requires 3 things: 1) grave matter, 2) full knowledge, and 3) full consent of the will.
Now a Protestant who gains the knowledge that he be Catholic and chooses not to commits mortal sin, and ceases to be a living member of the body. In fact, he ceases to be a member at all insofar as he is rejecting the Church with the knowledge of its veracity. Now a Protestant who never gains the knowledge of the Church’s truth remains a living member of the body, barring some mortal sin which would cause him to be a dead member of the body. Either way, he remains subject to the Roman Pontiff even if though doesn’t know it.
If a Protestant
does become aware at some point that the Catholic Church is God’s true Church, he will do one of two things. He will either obey, which will involve becoming Catholic, or he will refuse to obey. If he refuses to obey, he will be committing a sin of grave matter with the necessary knowledge and presumably with full consent of the will. Therefore, he ceases to be a living member of the body, and because he has rejected the Church altogether, he ceases to be a member at all. He is no longer be subject to the Roman Pontiff because he is outside of the body. If he repents of this sin, he will join the Church and make himself once more to the Roman Pontiff.
So what it comes down to is that all Protestants who know of the truth of the Catholic Church are outside of the body and cannot be saved, whereas all Protestants who do not know of the truth may still be members of the body, which is the Church, and since the Church is subject to the Roman Pontiff, so are these Protestants, even if they don’t know it.
