Peter wasn’t a pope. Catholics claim that, but the orthdox trace back to him as well. If you forget your Italian, German, French, Spanish, or English heritage, the orthodox view is extremely strong, that the Roman Catholics split away from the Christian church, and not vice versa.
I think there were some pretty violent Roman Emperors who were popes, whatever a ‘Pope’ is. I don’t remember seeing that word in the Bible either.
He wasn't just a pope, he was the first pope, named by Christ Himself.
The Orthodox were Catholic for the first ten centuries of the Chruch’s existence and supported the papacy, to which numerous quotes from the Chruch fathers East and West can attest.
My heritage is Russian, by the way.
