But, see my previous post, indefectibility is really the crux of the issue. I've long argued that SVs and R&R are quibbling about the wrong thing, the precise limits of infallibility in the strict sense. That's to mistake the trees for the forest.
Your previous post was an extreme exaggeration and over simplification. Over the past year I have personally become convinced that a key aspect of the plan of those who infiltrated the Church was to introduce misleading ambiguities - statements that are, per se, true, but
seem to be false - in order to cause an overreaction that would lead Catholics to conclude that the Church had defected. Exactly what you have done.
I don't have time to go into it now, but thus far, every apparent error or heresy of Vatican II that I have carefully looked into is, believe it or not, a true statement. At most it is ambiguous, but usually the proposition is true
and denying it is an error. But the way these are phased gives it the appearance of error, or else little known distinctions are not explained that would clarify
why the statement is true. And in many cases Rome could have very easily clarified these points, but they didn't. And it isn't just Vatican II. After the Council we had similar true but apparently false teachings. If you read them superficially, they can convey to the intellect an error; but if you read them carefully, what they actually say and not what they don't say, the proposition is false.
A priest friend mentioned one problematic statement to me a few days ago, and it is a perfect example of this. In De Verbum, we are told that the truths in Scripture that are put there "for the sake of our salvation" are inerrant. This teaching immediately cause people to conclude that historical and scientific truths in Scripture are not inerrant; but that's not what Dei Verbum says. All it says is what is contained in scripture for the sake of our salvation is inerrant. That is a true statement, as evidenced by the fact that the contrary is false. The contrary would be: "what is contained in scripture for the sake of our salvation is
not inerrant."
Dei Verbum never denies that inerrancy also extends to scientific and historical truths, it simply affirms that it extends to truths that pertain to salvation. Yet this true statement of Dei Verbum has been condemned as an error by many, and it has caused others to conclude that historical and scientific truths in Scripture could contain error.
This is one example, but there are MANY more. Again, I am now persuaded that these statements were intentionally inserted into the Council to cause an overreaction that eventually led Catholics to conclude that the Church had defected. And similar tactics were used in the liturgy and other areas. The devil is much more clever than we realize.
