Does Vatican I disprove Sedevacantism?

The “Perpetual Successors” Objection

After the objection that “you guys are just a bunch of Protestants!!”, probably the most frequently-made argument against Sedevacantism is that our position contradicts the teaching of the First Vatican Council that St. Peter will have “perpetual successors”.
