It would be good if the Scalfari comments could be substantiated by something other than a letter from Vigano.
If that wouldn't convince the "Francis no matter what" Newchurchers --- the Where Peter Is [sic] types --- that Francis was, at the very least, a heretic as a private "theologian", nothing would. (Whether a material or a formal heretic, he knew what the teaching of the Church was, so it would almost have to be formal heresy.)
