John Trapp on Philemon 1:2

Verſe 2. And to our beloved Apphia] For Appia: but this was the manner of pronunciation at Tarſus, S. Pauls countrey. This Apphia was (ſaith Theodoret) Philemons wife; whoſe good-will might make much to the furtherance of S. Pauls ſuit.

And Archippus our fellow-ſouldier] Who ſeems to have ſojourned with Philemon. See the Note on Col. 4.17.

And to the Church in thy houſe] Every Chriſtian family is a Church. But Phil mons houſe was (belike) a publike meeting. houſe, and ſo continued for many years after, as Theodoret witneſſeth.
