Yeah, it was...there was no one else there...the early church formed in the area and moved to Rome...P4eter was the titular head and it grew to what it is today from there....not complicated.
Such a useful myth for another religion, don’tcha think?
What 'area'?
Common sense wants to know.
Actually trying to get the the whole "acorn to tree" contrivance to work is quite "complicated," and you are going to have to find a whole lot more in invisible ink than moving Peter to Rome in order to produce the church of Rome out of the NT church, including the church looking to Peter as the first of a line of exalted heads, while Paul does not even mention Peter at all in his letter to the church at Rome, despite mentioning about 34 contemporary people.
And nowhere, including in any epistles to the churches or in the Lord's critiques of the churches in Rv. 2+3, is the NT church even told to submit to Peter as its head, nor commended for so doing or criticized for not doing so, including as a solution for any of their many problems that are mentioned.
Moreover, while Peter was the initial street-level leader among brethren, and the first to use the gospel-keys to the kingdom, (Col. 1:13) and whom Paul briefly stayed with for a little time - 3 years after a certain devout disciple had baptized and laid hands on the fasting Paul for his healing and filling with the Spirit, and he began preaching, (Gal. 1:16-18) yet in the ecumenical council of Acts 15 it is James "the brother of the Lord," who provided the Scripturally substantiated final judgment, confirmatory of Peter and Paul. And in the only mention of Peter in any epistle as being active in leadership, then he is mentioned second behind James, (Gal. 2:9) who also is the only one named in Acts 21 where Paul is exhorted as to what he should do concerning the Jews (Acts 21:15-26) It is also not not that, among many other things befitting a pope (which he was not), Paul is the only apostle recorded has having actually called a council of elders, (Acts 20:17) and to have rebuked another apostle, (Galatians 2:11) and call himself "father," (1 Corinthians 4:15).
