Introduction — Duties of Masters
The halakhah of the duties of masters in the New Testament accomplishes 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.
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 do not receive a separate chapter: they mirror those of the servant. The text specifies: "abstaining from threats (ἀνιέντες τὴν ἀπειλήν), knowing that your Lord and theirs is in heaven (ὁ κύριος αὐτῶν καὶ ὑμῶν), and that with him there is no respect for the quality of persons (προσωπολημψία)." The Greek term προσωπολημψία — a hapax formed to designate God's absolute impartiality — invalidates every earthly hierarchy as the foundation of human worth.
Colossians 4:1 condenses the duties of masters in 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: whoever exercises earthly authority is first of all subject to heavenly authority.
John Chrysostom in the 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 arrogance (μετὰ πικρίας), since they hope in the same God" — the communion in eschatological hope grounds the prohibition of arrogance.
The Old Testament root is twofold: Job 31:13-15 offers the most explicit testimony in the OT: "If I have despised the right of my servant... what shall I do when God arises? [...] Did not he who made me also make him?" — the recognition of common creation grounds the master's responsibility. Deuteronomy 15:12-18 establishes that no one can 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 case of the halakhah of the duties of masters: Paul asks Philemon to receive Onesimus "no longer as a slave, but as a beloved brother (ἀδελφὸς ἀγαπητός)". The change is not juridical but ontological — in the Christian community the duty of the master includes the recognition of the servant as a brother in faith.
The rabbinic tradition teaches that every man is created in the image of God (Gen 1:27) — a principle that the Tannaim apply as the foundation of the prohibition of humiliating anyone, free or servant. This converges with the Pauline theology of divine impartiality (Rom 2:11; Eph 6:9): the halakhah of masters is rooted in the theology of creation.
| Text | Master's duty | Key Greek term | Theological foundation |
|---|---|---|---|
| Eph 6:9 | Do the same toward servants | τὰ αὐτά (the same things) | Divine impartiality |
| Eph 6:9 | Abstain from threats | ἀνιέντες τὴν ἀπειλήν | One Lord for all |
| Eph 6:9 | Recognize a single Lord | ὁ κύριος αὐτῶν καὶ ὑμῶν | No προσωπολημψία in God |
| Col 4:1 | Give justice | τὸ δίκαιον | Juridical obligation, not charity |
| Col 4:1 | Give equity | ἡ ἰσότης | Structural equality |
| Phlm 1:16 | Receive as brother | ἀδελφὸς ἀγαπητός | Ontological transformation |
- The duty of the master is symmetrical to that of the servant (Eph 6:9 — τὰ αὐτά)
- Abstention from threats is the practical criterion of Christian authority
- Justice and equity are juridical obligations, not discretionary options (Col 4:1)
- The christological transformation precedes and motivates every social reform (Phlm 1:16)
How to practice the duties of the master today
- Verification of symmetry (Eph 6:9 — τὰ αὐτά): whoever exercises authority must examine whether his duties toward subordinates are symmetrical to the expectations he places on them — the halakhah of masters requires concrete reciprocity.
- Abstention from threat (ἀνιέντες τὴν ἀπειλήν): identify the forms of implicit threat in the exercise of authority — emotional pressure, veiled blackmail, coercive tone — and replace them with respectful communication.
- Apply τὸ δίκαιον καὶ ἡ ἰσότης (Col 4:1): give what is just and equitable before what is generous — justice is the floor of Christian authority, generosity is the ceiling.
- Meditate προσωπολημψία (Eph 6:9): recognize partiality of person as a sin that God does not tolerate and apply it in decision-making processes concerning subordinates.
- Practice the paradigm of Philemon (Phlm 1:16): actively seek the moment when the subordinate passes from "resource" to "beloved brother" — the duty of the Christian master culminates in the recognition of the common dignity of God's creatures.
