2 Corinthians 6

Introduction

This chapter continues Paul's defense of his apostolic ministry, flowing directly from his appeal in chapter 5 that he and his coworkers are "ambassadors for Christ." Paul urges the Corinthians not to receive God's grace in vain, citing Isaiah 49:8 to declare that "now is the day of salvation." He then presents an extended catalog of hardship, moving through sufferings, virtues, and paradoxes that authenticate his ministry not by outward credentials but by endurance under pressure.

The chapter then shifts. After an intimate appeal for the Corinthians to open their hearts to him as he has opened his to them (vv. 11-13), Paul issues a command that has prompted enduring debate: "Do not be unequally yoked with unbelievers" (vv. 14-18). Drawing on a chain of Old Testament quotations from Leviticus, Isaiah, Ezekiel, and 2 Samuel, Paul calls the Corinthian believers to separation from idolatry, a pressing concern in a city saturated with pagan temples and civic religion. The precise scope of this command, whether it addresses marriage, business partnerships, worship, or all of the above, has been debated for centuries.

The Urgency of Grace (vv. 1-2)

Notes

• Συνεργοῦντες ("working together") — This participle from synergeo means "to work alongside." Paul describes himself and his team as co-laborers with God — not independent agents but instruments of the reconciling work described in 2 Corinthians 5:18-20. The word implies not equality with God but participation in His mission.

• εἰς κενὸν ("in vain / to no effect") — Literally "into emptiness." The grace of God can be "received" in a formal sense while producing no transformation. Paul is not suggesting that God's grace is ineffective in itself but that human response matters — the Corinthians must not let the reconciliation God has accomplished in Christ be met with indifference or compromise.

• The quotation in verse 2 comes from Isaiah 49:8, part of the second Servant Song, where God promises to hear His Servant and through Him restore Israel and be "a covenant for the people." Paul applies this messianic promise to the present moment: the "acceptable time" that Isaiah anticipated has arrived in Christ.

• εὐπρόσδεκτος ("supremely acceptable") — Paul intensifies the Isaiah quotation: where the original has δεκτῷ ("acceptable"), Paul writes the strengthened compound euprosdektos — "well-received, highly favorable." The prefix eu- strengthens the word beyond simple acceptability. This is not simply an acceptable time but the time Isaiah had in view.

The Marks of Authentic Ministry (vv. 3-10)

Notes

• προσκοπήν ("cause for stumbling / obstacle") — This word appears only here in the New Testament. It refers to something that causes another to trip or fall. Paul is keenly aware that the conduct of ministers reflects on the gospel itself. The related verb proskoptō is used in Romans 14:21 for causing a brother to stumble.

• διακονία ("ministry / service") — This key term in 2 Corinthians (used over a dozen times in the letter) does not refer to a formal office but to the work of serving God's purposes. Paul's concern is not his reputation but the reputation of the ministry entrusted to him.

• The catalog in verses 4-10 follows a deliberate rhetorical structure. It moves through three phases: (1) nine hardships endured (vv. 4b-5), grouped in three triads; (2) eight virtues and resources displayed (vv. 6-7); (3) seven paradoxes of apostolic experience (vv. 8-10), each structured as an apparent negative paired with a deeper positive reality. The progression reflects the pattern of the gospel itself: suffering that gives way to life.

• θλίψεσιν ... ἀνάγκαις ... στενοχωρίαις ("afflictions ... hardships ... distresses") — The first triad describes internal pressures. Thlipsis means "crushing pressure" (from the image of pressing grapes or olives). Anankē refers to inescapable necessity or compulsion. Stenochōria literally means "narrowness of space" — the feeling of being hemmed in with no escape. Together they convey relentless pressure. Compare the similar hardship lists in 2 Corinthians 4:8-9 and 2 Corinthians 11:23-28.

• ἀκαταστασίαις ("riots / disorders") — This word can refer to either external tumults (mob actions, as Paul experienced in Acts 19:23-41 at Ephesus) or internal instability. Given its placement alongside beatings and imprisonments, the sense of public civil disturbance is primary here.

• ἀγάπῃ ἀνυποκρίτῳ ("love without pretense / sincere love") — The adjective anypokritos literally means "without hypocrisy" (from hypokrisis, "play-acting"). In a context where Paul's opponents may have accused him of insincerity, he insists that his love for the Corinthians is not a performance. The same phrase appears in Romans 12:9: "Let love be without pretense."

• ὅπλων τῆς δικαιοσύνης τῶν δεξιῶν καὶ ἀριστερῶν ("weapons of righteousness for the right hand and the left") — In Roman military imagery, the right hand held the offensive weapon (sword) and the left hand held the defensive weapon (shield). Paul's "weapons of righteousness" equip him for both attack and defense. This military metaphor is expanded in Ephesians 6:11-17.

• The seven paradoxes in verses 8b-10 are the rhetorical climax of the passage. Each uses ὡς ("as / regarded as") to contrast the world's perception with the deeper reality: "as deceivers, and yet true." The paradoxes echo the cruciform pattern that defines Paul's theology: the cross reveals that God's power works through apparent weakness (2 Corinthians 4:7-12, 2 Corinthians 12:9-10).

• πτωχοὶ πολλοὺς δὲ πλουτίζοντες ("poor, yet enriching many") — Ptōchos describes the most extreme poverty — not merely the working poor but the destitute. Yet Paul's ministry makes others spiritually rich. This paradox mirrors Christ Himself: "Though He was rich, yet for your sake He became poor, so that you through His poverty might become rich" (2 Corinthians 8:9).

Paul's Open Heart (vv. 11-13)

Notes

• Τὸ στόμα ἡμῶν ἀνέῳγεν πρὸς ὑμᾶς ("Our mouth is open to you") — The perfect tense aneōgen ("has been opened and remains open") indicates Paul's ongoing posture of transparency. He has held nothing back in his communication with the Corinthians. This is a personal moment: Paul breaks from his theological argument to address them by name, "Corinthians," which he does only here and in 2 Corinthians 11:11 in this letter.

• πεπλάτυνται ("has been opened wide / enlarged") — This verb means "to make broad, to widen." Paul's heart has been made spacious; there is room in it for the Corinthians. The imagery echoes Psalm 119:32: "I will run in the way of Your commandments when You enlarge my heart." There is no cramped or calculating reserve in Paul's love for this church.

• σπλάγχνοις ("affections / inward parts") — Literally "entrails" or "intestines." In the ancient world, the viscera were considered the seat of deep emotion (much as we speak of "gut feelings"). Paul says the constriction is not in his heart but in theirs — their emotional response to him has become narrow and guarded, perhaps because of the influence of rival teachers.

• ἀντιμισθίαν ("fair return / recompense") — This rare word (only here and Romans 1:27 in the New Testament) means "a corresponding repayment." Paul frames his request in the language of reciprocity: he has given them his open heart; the fair return is for them to do the same. The address "as to children" reveals the depth of his parental affection: he is their spiritual father (1 Corinthians 4:15).

Do Not Be Unequally Yoked (vv. 14-18)

Notes

• ἑτεροζυγοῦντες ("unequally yoked / mismatched") — This vivid word appears only here in the New Testament. It is a compound of heteros ("different, other") and zygos ("yoke"), evoking the image of two different animals yoked together for plowing. The background is Deuteronomy 22:10: "Do not plow with an ox and a donkey yoked together." Animals of different natures pull in different directions, making the work unworkable. Paul applies this agricultural law metaphorically to relationships between believers and unbelievers. The translation "mismatched" preserves the sense of fundamental incompatibility without limiting it to one specific kind of relationship.

• ἀνομίᾳ ("lawlessness / wickedness") — Literally "without law" (a- + nomos). Paul uses five rhetorical questions in rapid succession (vv. 14-16), each contrasting two irreconcilable opposites: righteousness and lawlessness, light and darkness, Christ and Beliar, believer and unbeliever, the temple of God and idols. The sequence builds until the point is plain: these pairs cannot coexist.

• Βελιάρ ("Beliar") — This name for Satan does not appear elsewhere in the New Testament but was common in Jewish intertestamental literature (especially the Testaments of the Twelve Patriarchs and the Dead Sea Scrolls). The Hebrew form Beliyyaal appears frequently in the Old Testament meaning "worthlessness" or "wickedness" (e.g., Deuteronomy 13:13, "sons of Belial"). Some manuscripts read "Belial." By pairing Christ and Beliar, Paul frames the issue in cosmic terms: this is not about personal preference but about allegiance in a spiritual conflict.

• ναὸς Θεοῦ ζῶντος ("temple of the living God") — ναός refers specifically to the inner sanctuary (as opposed to hieron, the whole temple complex). The believers themselves — corporately — are God's dwelling place. Paul made a similar point in 1 Corinthians 3:16 and 1 Corinthians 6:19, but here the emphasis is communal: "we are the temple." If God's holy presence dwells among His people, there can be no room for idolatrous compromise.

• The chain of Old Testament quotations in verses 16-18 is a composite drawn from several texts: Leviticus 26:12 and Ezekiel 37:27 ("I will dwell among them and walk among them"); Isaiah 52:11 ("come out from among them and be separate ... touch no unclean thing"); and 2 Samuel 7:14 ("I will be a Father to you"). Paul weaves these together into a single prophetic argument: God's covenant promise to dwell with His people demands their separation from idolatry, and the result is adoption into God's family.

• ἀφορίσθητε ("be set apart / be separate") — From aphorizō, the same root that gives us "Pharisee" (one who is "separated"). The aorist passive imperative calls for a decisive break. Paul is not calling for withdrawal from society altogether — he explicitly rejected that in 1 Corinthians 5:9-10 ("I did not mean the people of this world"). The separation concerns spiritual allegiance and participation in idolatry, not social isolation.

• Παντοκράτωρ ("Almighty / All-Sovereign") — This title for God appears frequently in Revelation but only here in Paul's letters. It translates the Hebrew Shaddai or Tseva'ot ("of hosts"). The promise of divine fatherhood comes from the mouth of the "Lord Almighty," the God who rules over all powers and kingdoms. Paul adds "daughters" alongside "sons" — 2 Samuel 7:14 mentions only "a son" — expanding the covenant promise explicitly to include women in the family of God.

Interpretations

The command "do not be unequally yoked with unbelievers" has generated significant interpretive debate regarding its scope and application:

• Marriage and romantic relationships. Many interpreters, especially in the evangelical tradition, see this as the primary application: Christians should not marry non-Christians. While Paul does not use the word gamos ("marriage") here, the yoke metaphor suggests a binding, long-term partnership, and marriage is the most intimate such partnership. Supporters note that the Old Testament background in Deuteronomy 7:3-4 explicitly forbids intermarriage with pagans to prevent idolatry. Others point out that Paul addressed mixed marriages separately in 1 Corinthians 7:12-16 and did not command separation from an unbelieving spouse already married.

• Broader partnerships and alliances. Many Reformed and Puritan commentators apply the principle more broadly to any deep alliance — business partnerships, binding legal agreements, or institutional affiliations — where a believer would be structurally joined to unbelievers in ways that compromise faithfulness to Christ. The agricultural metaphor of the yoke supports this reading: any arrangement where two parties must "pull together" toward a common goal is in view.

• Participation in pagan worship. Given the Corinthian context, a strong case can be made that Paul's immediate concern is participation in idolatrous temple meals and civic religious ceremonies. Corinth was home to temples of Aphrodite, Apollo, Poseidon, and the imperial cult. Many social and business activities were intertwined with pagan worship. The five rhetorical contrasts (vv. 14-16) culminate in the temple/idol contrast, and the OT quotations all concern cultic purity. This reading sees the passage as addressing the same issue as 1 Corinthians 8:1-13 and 1 Corinthians 10:14-22 — the danger of idolatry — rather than introducing a new topic.

• The question of separatism. Some traditions (certain Anabaptist and fundamentalist groups) have taken this passage as a call to comprehensive separation from "the world" — including separation from other Christians deemed insufficiently pure ("secondary separation"). Most Protestant interpreters reject this reading as inconsistent with Paul's own practice of engaging Roman society and his explicit instruction in 1 Corinthians 5:9-10 that believers must remain in the world. The separation Paul calls for is spiritual and moral, not geographic or social.

Most interpreters acknowledge that the principle has multiple legitimate applications but agree that the core concern is the preservation of undivided allegiance to Christ. The passage does not define the specific forms that "yoking" might take, which suggests Paul intended a principle broad enough to address whatever entanglements threatened the Corinthians' faithfulness to the gospel.
