Scriptorum -- I agree with you on matters of prudence and I don't think we should be quick to label anyone a heretic, but I disagree with you on this statement:
Quote:There is certainly a push to extend this into a dogma concering the physical effects on her body, if any, but that is not at all part of the authoritative teaching at this point and forbidding dissent or discussion.
It's clear that the dogma DOES contain the physical integrity of Our Lady, even if this cannot be proven from the premise of her perpetual virginity alone. Suarez, for instance, on the issue, says that Christ could have had a natural birth (pass through the birth canal) via some supernatural means other a miraculous arriving as a beam through glass. This could be for instance, by a supernatural widening of the natural canal that didn't destroy the physical integrity. These are the kinds of physiological details that Ott and others are clear about leaving open. However, you'll notice that in all these Thomistic examples, the physical integrity is emphasized and affirmed as if it were beyond question.
I found a new comprehensive analysis of the dogma in German which you may want to take a look at (
http://www.katholisches.info/2012/07/11/...of-muller/). Among the more interested things I can glean from the article are the following:
1. There was a 1960 admonition of the Holy Office, in the discussion about the virginitas in intrapartum against currents opposed to the traditional Thomistic understanding
2. The article traces a line from Mitterer to Karl Rahner, who also advanced a proposition similar to what Müller does. The article claims this makes Müller's view at least tenable in light of Rahner's complete "orthodoxy," but I doubt many here would accept that premise ;)
3. The author goes on to say that the SSPX has a valid point in pointing out that the traditional understanding of the dogma is concerned with physiological details
4. There is tension between the true natural birth of Christ and the physical integrity of Our Lady (notice, however, how this presupposes the physical integrity) ... this is resolved by Suarez's theory as I mentioned above -- a natural birth process accomplished by supernatural means
I think the key thing that you appear to be missing is the sense of dogma as defined by the Fathers. To them virginitas in intrapartum has a definitive physical meaning. Therefore, we MUST accept, with deference to the sense that they understood the dogmatic teaching, that their conclusions were true even if "virginitas" doesn't have anything strictly speaking to do with "virginitas in intrapartum," as modern physiological understandings have shown.
