I recently posted some videos on the topic of sedevacantism. Please know I am not a sedevacantist. Still, I do find this somewhat of an interesting topic, and for some it’s particularly timely because of a plethora of criticism of Pope Francis and the current state of the Church. I imagine the sedevacantists are having a field day with all of the scandals, and perhaps getting more inquiries than normal.
John Salza is an author who has taken on the sedevacantists. Here is a two-part interview he gave to Brother André Marie on that topic, which I think is pretty good.
Again, I know very little of sedevacantism, and I’m no canon lawyer, so a lot of this is over my head. My take is to generally dismiss the sedevacantists as crackpots, but I can’t entirely deny some of their concerns, and I assume many of them have some integrity. But I just can’t accept their position. Salza and Siscoe, co-authors of the book True or False Pope? Refuting Sedevacantism and Other Modern Errors, have been challenged by a number of sedevacantists. I have not really examined those challenges, but you can find them online. However, me sense is that those challenges are likely rather thin or outright silly.
The fact that Archbishop Lefebvre never gave into sedevacantism speaks volumes regarding the sedevacantists’ claims. Even when Lefebvre stood in strongest opposition to Rome, he always believed the Pope sat on his chair.
