[Elsie]

It's not about every random thing that a Pope thinks or says.

Heck; it ain't even everything that the apparition that Rome calls MARY says; either!

[Campion]

Something heard (or seen) in an apparition, even if the apparition is formally approved by the Church, is "private revelation," not "public revelation". Private revelation is not binding on anyone in faith, except perhaps to the person(s) who actually experience the apparition.
