If one has arrived at the conclusion that all groups are fatally flawed, and the only "pure" alternative is to give up the public practice of religion, ought it not indicate that such a person has erred somewhere along the way (lest indefectability be a lie, and therefore our religion false)?
And again, are not all these conclusions the result of private interpretations and judgments made by people completely unequipped to evaluate such matters?
I agree, these are serious questions I would have.
The whole "private interpretation/judgment" thing is a bit of a red herring though. We have the ability, the competence, to call a spade a spade. We know when the Pope is speaking things that aren't Catholic, or when they are trying to change the Catholic Faith into a Conciliar religion. But when exercising your private judgment leads to the conclusion "there are two-dozen Catholics left on earth, including my family, and no clergy" a little voice inside me would say, "BZZZZ! That can't be right. Go back to the drawing board, bub."
I mean, do these people not have such "sanity checks" on their faculty of reason? They just think that whatever they work out in their limited brain, it must be the truth, however insane it is? Is that stupidity, pride, or both?
Another thing I just "love" is how most people are UTTERLY UNABLE to change their mind, to adopt a new position to accommodate new data or an evolving situation. Maybe they went Home Alone in the 70's because it wasn't that crazy an idea -- maybe things would get fixed up in 5 years, right? But when year 45 came around, these people didn't bat an eye. What about when their first child lost the Faith? Do they ever re-consider that maybe they bet on the wrong horse? Human reason IS limited and fallible, after all. We shouldn't consider that our own judgement, our own opinions, are a hop, skip and a jump away from the Mind of God.
When we're not using faulty reasoning, we often have bad suppositions or "facts" that are anything but true. You can have a watertight, 100% logical argument but it's based on false assumptions -- and so the whole conclusion is false as well.
