Note 666 — EPISTLE TO PHILEMON.
Reading edition
Theodoret in his preface to the epistle says πόλιν δε εἶχε [[ὁ Φιλήμων] τὰς Κολάσσας· καὶ ἡ οἰκία δὲ αὐτοῦ μέχρι τοῦ παρόντος μεμένηκε. This is generally taken to mean that Philemon’s house was still standing, when Theodoret wrote. This may be the correct interpretation, but the language is not quite explicit.
