So the heretics want priestesses.  Nothing new.  Women cannot, under any circumstances, be legitimate priests.  No pope can change that; no council, no lay group, no theologian, absolutely no one. The editors are trafficking in full blown heresy - something for which they are notorious.
I say bring it on.  It will fully expose them as the heretics they are and force those who desire to remain Catholic to make a choice between the dying Protestant New Order sect and true Catholicism.
