I thought it really interesting that the Catholics start a thread with a article that admits that the time and teaching of Peter in Rome is really uncertain solved only on hypotheses.
From the article
As to the duration of his Apostolic activity in the Roman capital, the continuity or otherwise of his residence there, the details and success of his labours, and the chronology of his arrival and death, all these questions are uncertain, and can be solved only on hypotheses more or less well-founded.
I would shudder in fear if my faith and salvation was based on uncertain and hypotheses.
Ill stay founded on the Rock of Jesus.
Amen.I'll be right there with you brother.He's a big rock!
