Romans 16:5

Likewise the church that is in their house--The Christian assembly that statedly met there for worship. "From his occupation as tent-maker, he had probably better accommodations for the meetings of the church than most other Christians" [HODGE]. Probably this devoted couple had written to the apostle such an account of the stated meetings at their house, as made him feel at home with them, and include them in this salutation, which doubtless would be read at their meetings with peculiar interest. Salute my well beloved EpÃ&brvbrnetus, who is the first-fruits--that is, the first convert of Achaia unto Christ--The true reading here, as appears by the manuscripts, is, "the first-fruits of Asia unto Christ"--that is, Proconsular Asia (see Act 16:6). In Co1 16:15 it is said that "the household of Stephanas was the first-fruit of Achaia"; and though if EpÃ&brvbrnetus was one of that family, the two statements might be reconciled according to the received text, there is no need to resort to this supposition, as that text is in this instance without authority. EpÃ&brvbrnetus, as the first believer in that region called Proconsular Asia, was dear to the apostle. (See Hos 9:10; Mic 7:1). None of the names mentioned from Rom 16:5-15 are otherwise known. One wonders at the number of them, considering that the writer had never been at Rome.
