I don't know what to make of this as I've never been there. But it sounds true enough
from The Devil's Advocate
Morris WestThe next step was the Chair of Peter; but this was a high leap, halfway out of the world and into a vestibule of divinity. The man who wore the Fisherman's ring and the triple tiara carried also the sins of the world like leaden cope on his shoulders. He stood on a windy pinnacle, alone with the spread carpet of the nations below him, and above the naked face of the Almighty. Only a fool would envy hm the power and the glory and the terror of such a principality.
I can't speak to the truth of it, but I certainly hope that it is with thoughts like these that any person approaches the Chair. I suppose it's a Catch 22--if you really want the position, you are undoubtedly not qualified for it.
