The Vatican has not taken legal measures against Scalfari to take away his journalist's credential but instead Bergoglio is playing a game with him causing damage against Catholic doctrine

In 2018 Riccardo Cascioli published in the La Nuova Bussola Quotidiana: Scalfari and the Pope: A farce that has to end 

Finally, at this point he is a repeat offender, legal actions against Scalfari should also be evaluated.  If it is true that he takes advantage of a friendship and perhaps of a weakness of the Pope intending to cause disorder in the Church; certainly the Italian association of journalists would have the obligation to intervene as it likely has for less important things against other colleagues.

Anyone who being able to avoid it allows this farce to advance is complicit.

It is necessary that Bergoglio make a  profession  of faith.

Pope Francis and his spokesman Scalfari, the Vatican denial that denies nothing.

By SPECOLA ´The subject is so serious that, if it were true, God forbid, what Scalfari affirms without a doubt, Pope Francis would not be the Pope because he was not a Christian, that simple and that terrible ... There are many of today's articles that touch on this subject.  In general they try to defend that Pope Francis is a Christian, but all agree that a clarification is essential and that what has been said does not convince and creates enormous confusion. The only one who can do it is Pope Francis in person, don't serve any denials, from anyone or claims in defense of another person's faith. The profession of faith is personal, never collective, and in this case, it affects the essence of the Christian faith. The argument that we are facing two elderly people who are perhaps losing their abilities makes it even worse because it would incapacitate Scalfari as an interviewer and Pope Francis for the job he performs.
