We have already discussed the non-dogmatic nature of the 1976 and 1994 documents.  See Responses 2 and 7 in this chronology:

Please take time to read the chronology from beginning to end, and let me know if you find anything specific that is either historically false or dogmatically erroneous.

It is not a matter of redefining reality.  What is wrong is *assuming* that we already have complete and full understanding of reality, let alone revealed truth.  The faith is always the same yet the source or ever new light (Fidei Depositum #2, cf. Matthew 13:52).

It is not a matter of changing what is unchangeable.  It is a matter of discerning what is changeable and what is unchangeable.  Revealed truth is unchangeable.  The male-only priesthood has never been infallibly defined to be a revealed truth that is unchangeable.  As along as such infallible dogma is not proclaimed, it is should not be assumed to be unchangeable.
