Introduction — Fraternal Correction
The New Testament inherits from the Jewish tradition the mitzvah of tokhahat (תּוֹכַחַת) — the precept of fraternal reproof — and reinterprets it in the key of the messianic community. Lv 19:17 formulates the tokhahat as a positive obligation: «reprove your neighbor openly, so that you will not incur sin because of him». Correction is not a discretionary choice but a covenantal responsibility: one who remains silent before a brother's sin becomes co-responsible. The Babylonian Talmud (b.Arakhin 16b) radicalizes the principle: one must correct «even if the brother's face turns crimson», even a hundred times. Mishnah Avot 2:5 establishes the preliminary hermeneutical criterion: «do not judge your companion until you have reached his place» — authentic correction arises from understanding, not condemnation.
The Procedure of Mt 18:15-17: A Three-Stage Process
Mt 18:15-17 is the founding text: «if your brother sins against you, go and correct him between you and him alone (elenchos metaxy sou kai autou monon); if he listens to you, you have gained your brother. If he does not listen to you, take with you one or two persons (paralambe meth' heautou eti hena ē dyo), so that every word may be confirmed by the mouth of two or three witnesses (Dt 19:15). If he will not listen to them, tell the assembly (eipon tē ekklēsia)».
The structure is juridical — a progressive process that respects the dignity of the brother and allows space for teshuvah before proceeding: (1) private correction — confidentiality protects the brother's honor; (2) two witnesses — explicit reference to Dt 19:15, inscribing the correction within the halakhic framework of testimony; (3) assembly — the community as final tribunal. 1QS 5:24-6:1 of the Qumran Community Rule demonstrates that this same schema was operative in the Second Temple period: fraternal correction is obligatory within the community of the renewed covenant. Sir 19:13-17 formulates the sapiential principle: «reprove your neighbor before believing in his guilt».
Gal 6:1 — Correction as an Act of Love
Gal 6:1 specifies the spiritual dispositif of correction: «brothers, if a man is caught in some transgression (en tini paraptōmati), you who are spiritual (hoi pneumatikoi) restore such a person with a spirit of gentleness (en pneumati prautētos), each one watching over yourself, lest you too be tempted». Three elements are decisive: (a) «caught» (katalēphthē) — one does not seek out the sins of others but responds to what manifests itself; (b) «the pneumatikoi» — not those who consider themselves superior, but those led by the Spirit (Gal 5:22-23 had just enumerated the fruit of the Spirit, including prautēs/gentleness); (c) «watching over yourself» — authentic correction arises from awareness of one's own fragility.
Lc 17:3-4 formulates correction as an inseparable pair: «if your brother sins, rebuke him (epitimēson autō); if he repents, forgive him (aphes autō). And if seven times a day he sins against you and seven times returns to you saying: I repent, forgive him». Forgiveness is not conditioned upon accepted correction but offered every time the brother repents: the logic is one of restoration, not punishment.
The Responsibility of the Watchman
Ez 33:7-9 provides the prophetic framework: «I have appointed you as a watchman for the house of Israel. If you do not speak to warn the wicked from his conduct, the wicked will die for his iniquity, but I will require his blood at your hand». The metaphor of the watchman (tsophe) indicates that fraternal correction is not an exercise of moral superiority but a shared responsibility: one who knows and does not correct bears the weight of silence. This principle is inherited by the NT: Gc 5:19-20 affirms that «whoever turns a sinner from the error of his way will save his soul from death and will cover a multitude of sins».
Rm 15:14 describes the mature community as capable of this reciprocal responsibility: «I am persuaded, my brothers, that you also
