Spadaro is mistaken. The answer has never been given clearly. It was only exposed when Bergoglio's private letter to the bishops of Argentina was leaked. It took the Vatican days to admit that the letter was authenic.
Bergoglio is, by nature, a stealth heretic. And sometimes a public one.
I think we’ve successfully reached the point that I’ve seen suggested elsewhere. His silence is consent for the misinterpretations — for if he answers one way he is outed as a heretic, and if he answers the other, his revolution dies.
