Your misunderstanding about Catholicism are many.
All educated Catholics realize Pope’s are not infallible, except in limited circumstances. And you are correct Paul’s chiding of Peter demonstrates that.
And indeed, Luther was not infallible, but see my post about Lutherans now joining the RCC.
Please correct my mistakes, and I say this with all humility out of wanting to know more on the topic.
What I wrote is what my research showed.
The Twelve had a special dispensation and special anointing. And while many try to say that they are Latter day Apostles on par with Peter and Paul, like Joseph Smith or NAR charismatics, this is just not so.
No one who lives today can claim to be a witness of Christ in His ministry on earth; no one who lives today has written or was partakers of how the NT was written.
Luther, in my opinion, wanted to excise error. While that is a worthy Christian stance, it does not put his thoughts or words on par with the New Testament in terms of it’s “logos” power as being “the Word made flesh”.
Correct me if wrong, and thank you for responding.
