First of all, this response is nonsensical, period.
This thread is quickly becoming one where there are those who deny Peter was even at Rome etc. and that would be silly as well.
The point of the argument against St Peter actually being the first Bishop of Rome is that he was an Apostle with all the powers of a bishop but who: 1) established the Church at Rome (the fact that others preached Christianity there prior to him or that St Paul also ordained clergy does not take away from that); 2) Consecrated the first Primate of the Church of Rome in addition to others who became successors of that first Primate; 3) was not himself the bishop of the place since, as an Apostle, that was not his role and; 4) also established Churches and consecrated their primates and bishops in many other places.
There can be NO doubt that the Pope of Rome is St Peter’s successor as the successor of the Apostle himself. Whether or not Peter was the Bishop of Rome has NO bearing on that. The fact that Peter was the founder and consecrator of the Bishops of Rome is what is important.
If someone wants to believe he was the first Bishop of Rome - fine, I say. This thread is getting to be ridiculous.
