Cardinal Burke pointed this modus operandi years ago. Catholic tradition is built on the teachings of the PAST! However, he observed that Francis either cites himself [really the ghost writer quoting the "big guy" to curry favor] or documents since Vatican II. When an ancient source is referenced, it's mangled beyond comprehension - often to mean the exact opposite of the original!

When the Church recovers her senses, it won’t be difficult to excise this whole sorry, self-referential era, I guess. There is nothing good to preserve.
