Exactly.
However clearly or intelligently you argue, or how "good" you think your opinion is, in the end it will never by more than your personal opinion.
Fundamentally, we are lacking dogmatic clarity on the exact nature of the Crisis in the Church. Until God intervenes and clarifies the situation for us all, there WILL BE some confusion or disagreement as to the exact nature of the Crisis. The correct course of action will always be inconclusive, or a matter of personal prudence, or opinion.
You can't condemn Catholics for having a different opinion than you. If they are baptized and have the Catholic Faith (they accept everything the Holy Catholic Church teaches), they are Catholic, period. You must be in communion with them in order to be Catholic yourself. You can't shun part of the Mystical Body of Christ unless YOU want to cut YOURSELF off from it.
So, your responise appears contradictory. I agree with most of what you said after the "Exactly", but you were saying exactly to a statement from Stubbonr that contradicted your next sentence. He was saying that Father Wathen's opinion on "una cuм" is "absolute truth".
Unless Wathen somehow had some direct inspiratio fromt the Holy Ghost, his position too will "never be more than [his] personal opinion", as you then stated.
Yes, this is precisely what I was saying, except that your opinion can be MORE than JUST your opinion, and there's a bit of gray area between just your opinion (flip a coin, 50-50 shot it's right) and dogmatic certainty. I think someone can construct arguments that render it more than JUST an opinion, i.e. where it's basically moral certainty. Theologians do that all the time where they hold that certain conclusions are "theologically certain", where they are certain based on a close logical connection to various revealed truths that we know to be true ... and yet because they're just logical conclusions they're not "de fide" or even proximate to faith, etc. That's precisely the error that Dimonds and many dogmatic SVs make, where they construct a very solid syllogism based on dogmatic truths, and then declare their conclusion to be dogmatically certain. No. As soon as you start layering logic on top of a dogmatic premise, it's no longer dotmatically certain. If it's just a tiny logical step removed from a dogmatic truth, it might be "proximate" to dogma (i.e. extremely close where no one can see how it isn't), but if it's a little more removed, then theologically certain, then probable, etc. There are different degrees of certainty that a lof of individuals don't consider. This also plays into many shoot-from-the-hip accusations of heresy against the Conciliar papal claimants, where they might here an error uttered by the Pope and declare it heresy. "Where's the dogma he's contradicting?" In most cases, the accusations involve error that, while grave, fall short of being "de fide", where they're more "theologically certain". While the case can be made that you still sin against faith by rejecting something theologically certain, the distinction is crucial for the SV hypothesis, since you don't lose membership in the Church for denying a theological certainty or even rejecting something that's proximate to faith (and thereby being proximate to heresy).
Heresy is a much higher bar than just "error", but it's often used interchangeably, and incorrectly.
