*2) PRISCILLA: THE BEST CANDIDATE AS THE FOUNDER OF THE CHURCH OF ROME:
"Greet Priscilla and Aquila, my co-workers in Christ Jesus. They risked their lives for me. Not only I but all the churches of the Gentiles owe them a debt of gratitude. Greet also the church that meets at their house Romans 16:3-5)."
Their house church was their missionary base for evangelizing Roman Jews. Their missionary efforts were apparently the foundation of Christianity at Rome.
Once they begin to make converts there, the Jews riot against them. Emperor Claudius does not understand the issue behind the rioting, and so in 48 AD he expels all Jews from Rom Rome to end the trouble. That expulsion is the reason why Priscilla and Aquila are forced to abandon their house church and flee to Corinth:
"After this, Paul left Athens and went to Corinth. There he met a Jew named Aquila, a native of Pontus, who had recently come from Italy with his wife Priscilla, because Claudius had ordered all Jews to leave Rome. Paul went to see them (Acts 18:1-2)."
The Roman historian Suetonius also refers to Claudius' expulsion of Jewish Christians from Rome. What is the significance of the fact that Priscilla and Aquila are the only Christian missionaries identified as part of this expulsion? Since this expulsion reacted to the founding of the Church of Rome, Priscilla and Aquila emerge as the best candidates as founders of the Roman church!
But in 4 of the 6 times this couple is mentioned in the NT, Prscilla is mentioned before her husband--an unprecedented fact in first century patriarchal culture. Her priority likely means that she was the active missionary, while Aquila financed her efforts through his trade as a tentmaker (Acts 18:3 -4).
If so, Priscilla emerges as the most likely candidate as the founder of the Church of Rome, but never got credit for it, probably because she is a woman.
Linus or Peter are identified as the first bishops of Rome, but Peter doesn't arrive in Rome until c. 64 AD. The Church of Rome was actually founded around 48 AD. when Priscilla was doing her missionary work there.
