Romans 16:4

4.To whom not only I, etc. As Prisca and Aquila had not spared their life for preserving the life of Paul, he testifies that he himself was individually thankful to them: he however adds, that thanks were given them by all the Churches of Christ; and he added this that he might, by such an example, influence the Romans. And deservedly dear and precious to all the Gentiles was the life of such a man, as it was an incomparable treasure: it was therefore no wonder that all the Churches of the Gentiles thought themselves to be under obligations to his preservers. (472)

What he adds respecting the Church in their house is worthy of being observed; for he could not have more splendidly adorned their household than by giving it the title of a Church. The word congregation, which [Erasmus ] has adopted, I do not approve; for it is plainly evident, that Paul, by way of honor, had used the sacred name of Church. (473)
