Apostolic succession means that there will always be a valid pope. (And this is promised by Christ in Matthew 16:18). However, who happens to be pope and whether or not that pope is any good depends on us. Christ established the Church, not the particulars of how the Church is organised.
And from another perspective as Hilare Belloc puts it.
"The Catholic Church is an institution I am bound to hold divine — but for unbelievers a proof of its divinity might be found in the fact that no merely human institution conducted with such knavish imbecility would have lasted a fortnight."
But by all means, if bashing the Church if it makes you fell all intellectual like...
Nice bit of apologetics you got going there.
I notice you utterly failed to address the White Elephant In The Room: it appears there is no actual "higher authority" to sort out the very corrupt Catholic Church.
I look back on history? And you cannot even trace your linage to the "original"! Too many schisms, too many examples in history where there were multiple, directly-competing popes!
Which one was "divine", again?
What's worse, are the dozens of popes who were "selected" by the simple fact that the previous pope had been murdered by the current one (or his minions-- same thing).
There was a time, when the "natural" cause of death, of the pope, was ... poison.
Jesus was a lot of things, according to self-styled "experts". But nobody disputes he was a
pacifist most of all.
How do you think Jesus would have reacted to his "principle spokes-person"
being selected by the murder of the previous one?
