Actually, the CDF could and would oppose it, and it's highly unlikely that Francis would be able to stand up to that or that he could get anybody except the Gemran bishops and his aging Latin American liberation theology bishops to accept his authority in that case. Authority must be accepted in order to be exercised, and his would be rejected.
But we're not ou of the woods yet. What he plans to do is to dissolve the CDF - according to a Roman correspondent who seems to be in the know - and claim that its powers now reside with the local bishops' conferences, many of which are controlled by elderly liberals and most of which don't give a darn about what happens in Rome anyway, unless it agrees with them.
He removed Burke last year and this year he will simply get rid of the whole thing, because he sees the CDF (the former Holy Office of the Inquisition) as the only serious threat to him. And he's going to act fast, before opposition can coalesce. Radical leftists like the Pope - or Obama - have mastered the technique of acting rapidly, stealthily, and autocratically, knowing that their law-abiding opposition will be caught off guard and too dumbfounded and disbelieving to react in time. They're playing by the rules, but he's not, in true Alinsky fashion.
“Radical leftists like the pope”
A radical leftist wouldn’t condemn abortion, birth control, in-vitro fertilization, gender theory, gay marriage, etc, etc. A radical leftist wouldn’t always tie environmental issues to respect for human life. Some might say he’s just saying these things but doesn’t believe them. I don’t buy it. A radical leftist wouldn’t have promoted Cardinal Sarah, who is militantly orthodox.I wish there were more nuanced interpretations of Francis on here instead of the caricatures: Communist, Socialist, etc, etc.
What’s closer to the truth? I would say that maybe Francis thinks a liberalized Communion reception among the divorced without an annulment falls within orthodoxy somehow. John Paul and Cardinal Ratzinger looked at this question and said they couldn’t change anything. Does Francis at times take mercy too far, at least privately downplaying doctrine out of a misguided compassion?
