Are We in Serious Trouble in Christianity if We Don't Believe Them?

If apostolic succession is true, then peter probably had a successor. The evidence for t we see in several places. Hegastippus in one 60 has a list of popes ind against heresies saint ireneus does in one 80. There's no way that the people in the one hundreds are ignorant about whether or not their church actually was founded. And so i say, give in that like you have within the span of a lifetime.
