So we are supposed to take your word for it that the Catholic church is Christ's historic church?
When there is no mention of it in the Bible.
I can believe what the apostles say because their writings are in the Bible. Paul talks about a lot of different churches, but nothing in Rome.
Since you believe that Peter was the first pope, don't you suppose that Peter would have written something about the church in Rome?
Do you have anything from Peter?
