The Vatican said that what Curran pedals is not Catholic theology.  The Holy See has only direct jurisdiction over pontifical faculties, so it could not "order" a Catholic university that is legally an independent entity not to hire.  On the other hand, Ex corde Ecclesiae makes clear that bishops ought to say publicly whether an entity that calls itself "Catholic" is or isn't: in the late 1980s and early 1990s, there actually was some concern among Catholic academics that bishops might take that task seriously, as John Paul was urging them, so nobody picked up CC.  Over the years, Catholic colleges figured out that the Pope was far away and the USCC-NCCB toothlessly supine.  I would not be sure some "university in the Catholic, Jesuit tradition" today might not have do differently if l'affaire Curran happened today.
