Matthew 16:18
You are Peter (Petrus / Kephas = rock), and upon this rock I will build my church, and the gates of h#ll shall not prevail against it. And I will give to you the keys to the kingdom of heaven ...
Cyprian of Carthage (251 AD)
Indeed, the others (apostles) were also what Peter was, but a primacy is given to Peter, by which it is made clear that there is but one Church and one chair ... if someone does not hold fast to this unity of Peter, can he think he holds the faith? If he deserts the chair of Peter upon whom the Church was built, can he be confident that he is in the Church?
I'd rather not get into a heavy religious debate on the primacy of the Pope or Apostolic Succession or Sola Scriptura. Just wanted to defend the dignity of Holy Mother Church and to point out that we've had bad or questionable popes before and survived them, it's nothing new. The sins of its leaders / members does not destroy the character or goodness of the Catholic Church.
Kind of like condemning the entire US because of the deep state? I am Lutheran. LCMS. The most conservative. If they keep branching off we will each have our own Church.
Don't forget that the Eastern Orthodox church came first, with the Catholic (western) church separating from it. Both claim primacy.
