We had the organisations 'number 2', the Vicar General, Mgr Mariano Fazio, criticising the Filial Correction for 'correcting a father in public':
Any faithful, bishop, cardinal, lay person has the right to tell the pope what he sees fit for the good of the Church. But it seems to me that he has no right to do so publicly and to scandalize the whole Church with these manifestations of disunity.
I've responded to that in the linked LifeSite article.
Mgr Fazio is simply following, however, the line of the head of Opus Dei himself, Mgr Fernando Ocariz, who wrote an article for L'Osservatore Romano on December 2, 2011, indicating the kind of obedience which the documents of the Second Vatican Council have: remarks which presumably cover any reasonably high-level official documents of the Church.
