Liberals would love to say it's attitudinal.   That's how shallow their thinking is.

But the dubia are very precise questions about a document the pope wrote, with tie backs to Church teaching. The conflicts are quite apparent.  

This an action of the intellect not "attitudinal".

But the fact is the pope isn't an intellectual and ram-rodded through a sloppy mess on the force of his office (coyly wedging in a major fudge factor in a footnote no less) ; this was a very dumb and arrogant thing to do.  He doesn't create truth.

His progress will slow because he's losing a large number of cardinals and bishops who even though they respect the office of the pope...they respect the truth of the teaching of the Church far more.

You don't wave away these substantial questions with another silly interview and an air of dismissiveness.
