Not that it's very important, but I don't think Pio Vito Pinto is a bishop. I did find his name on the Catholic Hierarchy website, where he is listed as "Father Pio Vito Pinto", Dean of the Roman Rota. I think Pope Francis is responding to the 'dubia' appropriately; even eloquently. Silence is precisely the right response. 'Amoris laetitia' has been thoroughly sliced and diced. The great importance of AL is precisely that it does not attempt to provide a "one size fits all" solution to pastoral problems. The four cardinals and their supporters suffer from a pathological need to fit every person, every situation into a pre-fab slot. Francis is wise, and correct, not to bite. I suppose these four could precipitate a crisis in the church -- their egos seem fully engaged now. However, short of a crisis, I think Francis won't be taking their red hats away. I think Francis is secure and serene in his person and in his ministry and I think he has not, and will not, lose any sleep over this.
