When this sort of editorial comes from a
conservative Catholic news site, I begin to believe that the difference between the pro-Vatican II conservatives and the modernist liberals is eroding.
The modernists are least honest about building a new church, a new religion, founded on Vatican II. The conservatives keep claiming that Vatican II has been misinterpreted and is supposedly wholly consonant with the Catholic faith as it has been handed down from the apostles. They've been held hostage by the Vatican II establishment for so long that some of them have developed Stockholm syndrome.
Since the conservatives caved on so many issues, such as liturgical reform and ecumenism, it's no surprise that they caved on this one.
You confuse custom and Tradition, particular eras for orthodox faith. The Faith is the creeds and the Father's interpretation of them. Church customs differ. The Church allowed a married clergy for 11 centuries. That was one era. Then followed another. We are arguably marching into yet another era now which may require changes in disciplinary law.
