Since the Apostle Paul had not visited Rome, how had the Christian faith been introduced to the city? Apparently no other apostle had yet reached Rome, in the light of Paul’s stated purpose to be a pioneer missionary and to open virgin territory to the gospel (15:20). In particular, it is evident that Peter was not in Rome at that time because Paul expressed no greetings to him … .
Perhaps a partial answer to the founding of the church at Rome is the fact that “visitors from Rome” (Acts 2:10) were in the crowd that witnessed the miracle of Pentecost and heard Peter’s sermon. Some of them probably were among the 3,000 converts that day and returned to Rome as believers in Jesus Christ to propagate their faith. Other believers migrated to Rome through the years since Pentecost … . Aquila and Priscilla are good examples …. (Acts 18:2).

Our adult Sunday School class is studying the epistle to the Romans for the next two quarters. As I was finishing the lesson this morning, I came across the following question: “What would be your guess as to the origin of the church of Rome?” Before consulting a commentary, I guessed that Priscilla and Aquila might have been involved in planting the church, but really had no idea. That’s where BKCNT helped to put together the pieces.
