Didn’t you read his post 511?
You aren’t familiar with your own church history?
You can still comment on it if you read it even if you never encountered it before.
I read it, but it is full of heterodox theologians’ and revisionist historians as experts. They are not. There are only the ecumenical councils which teachings on faith and morals ratified by Pope and two Ex Cathedra statements which constitute infallible teachings. History only as reiable as hisorian. Johnson has an agenda.
Lots of misunderstandings on FR.
