Pope Francis......
...is the Pope.
I will say no more than to add: the Holy Spirit will protect him from teaching error.
This is my Faith. I know it is yours too. As it is every Catholic.
My parting thought (as well as the above): I feel the Holy Spirit uses men in ways we don’t expect. To keep our Faith alive.
I certainly believe that no Pope will be able to teach error in such a way that he is formally demanding the adherence of faith from the whole Church for these errors.
I do think the reason Pope Francis is so devious and equivocating, and downright double-tongued --- relying on devious spokesweasels, "confidential" personal conversations that get leaked, ambiguous footnotes and the like --- is that he would *like* to proclaim outright heresy but finds that he cannot.
Sort of like the mercenary Balaam in the OT, who wanted to prophesy curses against Israel, but couldn't: only blessings would come out of his mouth.
