[Hermann the Cherusker]

One must truly wonder whether the Seat is vacant.

I.e. one must truly wonder whether the promises of Christ have some validity? If you don't think they do regarding St. Peter's perpetual sucession (see Vatican I), I hear the Orthodox Church is looking for converts.

[Grey Ghost II]

Christ never promised the Seat would not be vacated. If he did, then a Pope would never die.
