Sorry, my mistake.  The point is that he says "declare," not "define"... so there were doubts, so the CDF one year later published the Dubium  to double down on this *declaration* that is not a *definition* and therefore not a dogma.  Ordinatio Sacerdotalis is an "executive order" (addressed to the bishops, not the entire Church) to stop discussion. Note that everything (in this paragraph and in the entire document) is in PAST or PRESENT tense.  Nothing is said about the possibility that the Church may attain a deeper understanding of the 12 apostles.  Nothing about the difference between the OLD LAW and the NEW LAW.  Nothing about the 12 apostles chosen under the OLD LAW to represent the patriarchs of the 12 tribes of Israel.  Nothing  about Mary being the Mother of God and Predecessor of the Apostles (Catechism 773).  Nothing about so many other things.  If this is a definition of a divinely revealed dogma, it is a very AMBIGUOUS definition indeed.  Sorry, by but my DOUBTS remain.
