The Way Of The Gentiles

Τὸ εἰς ὁδὸν ἐθνῶν μὴ ἀπελθεῖν, μὴ συνελθεῖν αὐτοῖς εἰς τὸ φρόνημα, ὡσαύτως καὶ εἰς πόλιν Σαμαρειτῶν μὴ εἰσελθεῖν, οὐχὶ τῆς συνοικήσεως ἀπεχόμενον, ἀλλὰ τῆς δυσσεβείας καὶ πονηρίας μὴ ἐφαπτόμενον. Ἅγιος Ἰσίδωρος Του Πηλουσιώτου, Βιβλιον Πρῶτον, Ἐπιστολή ΡΝΓ', Ἡρακλειδῃ Πρεσβυτερῳ Source: Migne PG 78.285b

In the way of Gentiles do not go, 1 do not join your thoughts with theirs. And likewise do not go into a city of the Samaritans. Not that one should spurn their company, but lest one should be seized by impiety and wickedness. Saint Isidore of Pelusium, Book 1, Letter 153, To The Presbyter Heracleides 1 Mt 10.5
