Introduction — Duties of Masters
The halakhah of masters' duties in the New Testament enacts a revolution in ancient domestic ethics: Ephesians 6:9 and Colossians 4:1 impose on the κύριος (lord, master) obligations symmetrical to those of the δοῦλος, recognizing that before the one heavenly Lord no privilege of status exists. The halakhah "Duties of Masters" is unique in the corpus of ancient ethics — no Roman code formulated such explicit reciprocal duties toward servants. This halakhah of the Christian master transforms authority from coercive power into responsible service.
The Tannaitic tradition offers a complementary foundation for this transformation of authority. Rabban Gamliel son of Rabbi Yehudah HaNasi teaches in Avot 2:2: "The study of Torah is beautiful when combined with a worldly occupation (דרך ארץ), for the toil of both causes sin to be forgotten." The principle carries direct implications for those who exercise economic authority: the dignity of labor belongs not only to those who perform it but also qualifies those who direct it. The dictum continues with a severe admonition: "Every Torah that is not accompanied by labor will ultimately cease and will bring sin in its wake." Authority exercised without participation in common toil — without דרך ארץ — forfeits its moral legitimacy. The master who withdraws from sharing in the responsibility of labor violates not only social ethics but compromises the very validity of his Torah study. This Tannaitic principle converges with the Pauline symmetry of Ephesians 6:9: those who command must know and respect the toil of those who obey, for both participate in the same economy of dignity before God.
τὸ δίκαιον καὶ ἡ ἰσότης: justice and equity as the measure of authority
Ephesians 6:9 formulates the principle with grammatical precision: "And you, masters, do the same things (τὰ αὐτά) toward them" — the phrase τὰ αὐτά creates a direct symmetry with the duties of the servant in Eph 6:5-8. The duties of the master receive no separate chapter: they are the mirror image of those of the servant. The text specifies: "refraining from threats (ἀνιέντες τὴν ἀπειλήν), knowing that their Lord and yours is in heaven (ὁ κύριος αὐτῶν καὶ ὑμῶν), and that before him there is no partiality (προσωπολημψία)." The Greek term προσωπολημψία — a hapax coined to designate the absolute impartiality of God — invalidates every earthly hierarchy as a foundation of human worth.
Colossians 4:1 condenses the duties of masters into two imperatives: τὸ δίκαιον (justice) and ἡ ἰσότης (equity). Not discretionary charity but juridical obligation — justice is owed, not granted. "Knowing that you also have a Master in heaven" — the reference to the heavenly κύριος is the theological foundation of the entire halakhah of the master: those who exercise earthly authority are themselves first of all subject to heavenly authority.
John Chrysostom in his homilies on Ephesians observes that the master who does not threaten expresses the Christian character of authority — not coercive power but responsible service that answers to the Lord. The Didache 4:10 formulates the principle with normative concision: "Do not command your servants with harshness (μετὰ πικρίας), for they hope in the same God" — communion in eschatological hope grounds the prohibition of harshness.
The Old Testament root is twofold: Job 31:13-15 offers the most explicit testimony in the Hebrew Bible: "If I have despised the cause of my servant... what shall I do when God rises up? [...] Did not he who made me in the womb make him?" — the recognition of common creation grounds the responsibility of the master. Deuteronomy 15:12-18 establishes that no one may be reduced to permanent slavery: the inviolable dignity of the servant must be respected.
Philemon: the christological paradigm of ontological transformation
Philemon 1:16 offers the most radical instance of the halakhah of masters' duties: Paul asks Philemon to receive Onesim
