The good of authority pertains to the essential nature of the Church itself, regardless of those who possess it.
What good is authority if it is being used to pervert, rather than promote, the Faith?
Which comes first, faith or authority? Authority without faith is worse than nothing; it is harmful.
I totally agree there are big, unaddressed holes in the strict sede view, which is why I am not an SV, strictly so called. However, I also see big, unanswered holes in the recognize-but-resist view. That said, this is NOT your grandfather's crisis; it is like an ecclesiastical nuclear wasteland and there is no "simple" answer. Unfortunately, BOTH dogmatic SV-ism AND dogmatic recognize-but-resist-ism act as if all is clear and those who disagree are stupid non-Catholics. Not only are such attitudes wrong, they are insuperable obstacles to real progress and unity.
