Donald Trump may be doing "us Catholics" a favour, sorta. The disgust at his recently revealed video and sound track actually represent a de facto example of our "legitimate teaching" authority teaching on the role of women in creation, in the here and now. The most recent and up-dated author, Joseph Cardinal Ratzinger, Prefect of the Congregation for the Doctrine of the Faith expressed this utilitarian  definition of women in his 2004,  "Letter to the Bishops of the Catholic Church on the Collaboration of Men and Women in the Church and in the World".
Nowhere does the notion that "words mean something" fit more than in our Catholic Church. Words of "legitimate teaching authority" are meant to direct behaviour and decisions and are the licence of clerics to dictate.
Before I begin to quote the official document that had/has the blessing of then Pope John Paul, remember that it has not been rescinded, worse, Cardinals, bishops, papal officials and Pope Francis I himself use it's words
