I wonder how many have lost their Catholic faith because of this pope, not their Christian faith, but their faith in the Catholic Pope as infallible in matters of religion.
If that was their "faith," they were in error. (I speak as an RCIA catechist.)
The pope is not infallible just generally "in matters of religion," but only when he is either (1) teaching something which is always/already infallible -- for instance, "Jesus is God" or (2)teaching something (again in line with the already established doctrine of the faith, and his infallible predecessors) which he solemnly states is to be accepted "de fide" (as an article of faith) and binding on conscience for all members of the Church everywhere and always. Which means, he is explicitly invoking his supreme authority ("ex cathedra")in a matter of faith and morals.
And, as is true of any type of legislation, it must be clear enough so everybody can figure out what is required by it, and what is forbidden. It can't be vague, ambiguous, equivocal, etc.
Nothing Pope Francis has stated on most of his pet subjects has ever fulfilled these requirements, and --- I suspect --- never will.
For one thing, this is because he seems incapable of clear speech. The man's mind shows itself to be confused and preoccupied with producing intentional ambiguity.
