Don't make eye-contact, don't bring it up in public.
Just give interviews about it ...
The last interview in which Cardinal Raymond Leo Burke suggested a “formal correction” of an alleged error the Pope made in his Apostolic Exhortation “Amoris Laetitia” has sparked a heated discussion. By brandishing “formal correction”, an institute that cannot be found in canon law, Burke seemed to be presenting Francis with some form of an ultimatum in light of the five “dubia” over the interpretation of the “Amoris Laetitia”.
In an interview with Vatican Insider, another of the three signatories of the “dubia”, German cardinal Walter Brandmüller, was keen to stress that a potential “fraternal correction” of a point made by the Pope must take place “in camera caritatis”, in other words not in public by means of published acts or written documents. - Source
