Let me go on: the RC doctrine of the Immaculate Conception, papal supremacy, papal infallability, purgatory, etc. are all things that confessional Lutherans reject, but the RC church has not. The Lutherans are not alone in this: the Eastern Orthodox Church rejects those teachings, as well.
What are you smoking?
They only slightly disagree on what Papal Authority entails, and on the formulae for filioque, which is far too complicated to get into here.
What do you know about Eastern Orthodox?
Certainly confessional Lutherans reject these (if they are doctrines of the Catholic church I can’t say as I prefer to let Catholics speak as to what their doctrines are). As for the EO, I defer to them if there are any left since the caucus war.
