Because you aren't interested in an answer, you're hoping for a blurb, without context or fullness (which sums up how Protestant doctrine comes about, btw). You don't really care about incredulity vs. apostasy vs. schism vs. heresy, either formal or material. You don't care about the balance between obedience and the need to rebuke. You don't care about the weight of Doctrine and the role of Sacred Tradition.
If I'm mistaken and you really do care, feel free to study up.
Again, a cop out.
The question remains unanswered as usual.
I find it interesting that Catholics won’t/can’t answer whether the Holy Spirit led the College of Cardinals in their selection of the pope.
John notes in two places we have all we need to know on how to have eternal life.
