V2 taught nothing infallibly.  Read LG 25 again.  There has never been an infallible definition, ordinary or extraordinary, that the male-only priesthood is a divinely revealed dogma.  Actually, in the early 1990s, it is a matter of public record that the bishops in many places were *actively*  discussing the ordination of women.  Not insignificantly, Ordinatio Sacerdotalis is addressed *to the bishops,* not to the entire Church, so it cannot possibly be a dogmatic teaching addressed to all the faithful.  Again, it is written in past and present tense, says nothing about the future, and does not say it is a definition.  Sorry, but the Pope was not speaking infallibly when he (via the CDF) said he was speaking infallibly; and the CDF is never infallible.  It is an authoritative edict for the bishops to stop discussing the issue officially, and contains a fallible statement about the presumed infallibility of a doctrine that has never been infallibly defined to be infallible.
