Matthew Poole and continuators on Romans 16:5

5. Likewise greet the Church that is in their house . Salute my well-beloved Epenetus, , who is the first-fruits of Achaia unto Christ .

The word Greet is supplyed to fill up the Sence. q. d. Declare my good Will to them, and Desires of their welfare. You have the same Salutations, 1 Cor. 16.19. And the like in Col. 4.15. Philem. 2. By the Church in their house, is generally understood, their Family or Houshold; which he calls a Church, because of the Godly Order and Religious Worship that was exercised amongst them. May Aquila and Priscilla be a pattern unto other House-Keepers; may the families of Christians be every where as little Churches. The House of George, Prince of Anhalt, for the good and Godly Order therein observed, was said to be, as well a Church, as a Court, There are some that think, That by the Church in their House, is meant the Christians that were wont to assemble there for Solemn Worship; but this is not likely, because of the particular Salutations of so many in the following Verses.

Epenetes, in the Greek Tongue, is Laudable and Praise worthy; so was this Person, both in name and in deed.

The same is affirmed of the house of Stephanus, 1 Cor. 16.15. The meaning may be this, Epenetes was the first Person, and Stephanus his Family, was the first Family that embrac't the Faith of Christ, Region of Achaia. This is a singular Commendation; Gods soul desires such first-ripe Fruits, Micah. 7.1.
