Romans 16:5

Salute the church that is in their house — Aquila had been driven from Rome in the reign of Claudius, but was now returned, and performed the same part there which Caius did at Corinth, Romans 16:23. Where any Christian had a large house, there they all assembled together though as yet the Christians at Rome had neither bishops nor deacons. So far were they from any shadow of papal power. Nay, there does not appear to have been then in the whole city any more than one of these domestic churches. Otherwise there can be no doubt but St. Paul would have saluted them also. Epenetus — Although the apostle had never been at Rome, yet had he many acquaintance there. But here is no mention of Linus or Cemens; whence it appears, they did not come to Rome till after this. The firstfruits of Asia — The first convert in the proconsular Asia.
