Interpretation of Adulterers in 1 Corinthians 6:9-10

The Apostle Paul, in 1 Corinthians 6:9-10, addresses the Corinthian church with a stern warning about the inheritance of the Kingdom of God, specifically listing "adulterers" among those who will not inherit it. The passage reads: "Or don’t you know that the unrighteous will not inherit the Kingdom of God? Don’t be deceived. Neither the sexually immoral, nor idolaters, nor adulterers, nor male prostitutes, nor homosexuals, nor thieves, nor the greedy, nor drunkards, nor revilers, nor swindlers will inherit the Kingdom of God" ^[1]. The broader context of this chapter involves Paul reproving the Corinthians for internal disputes, particularly for taking one another to secular courts over minor issues ^[7]. He uses this occasion to remind them of the moral standards expected of believers and to warn them against various gross sins to which they had formerly been addicted ^[7].

The term "adulterers" (μοιχοί, moichoi) in this list refers to those who engage in sexual intercourse with someone other than their spouse ^[5]. This prohibition is deeply rooted in Old Testament law, notably the Ten Commandments (Exodus 20:14), and is reaffirmed in the New Testament by Jesus himself (Matthew 5:27-28) ^[5]. The inclusion of "adulterers" in this vice list underscores the seriousness of sexual sin within Christian ethics. John Gill, in his commentary on 1 Corinthians, categorizes "adulterers" alongside "fornicators" and "effeminate" individuals, highlighting a range of sexual transgressions ^{[4, 3]}. The "effeminate" (μαλακοί, malakoi) are described as "self-polluters, who submit to unnatural lusts" ^[3], while "male prostitutes" (ἀρσενοκοῖται, arsenokoitai) and "homosexuals" (often translated as "men who submit to or perform homosexual acts") are also explicitly mentioned ^{[1, 2]}. This comprehensive list emphasizes that various forms of sexual immorality are incompatible with inheriting the Kingdom of God ^[5].

The phrase "Don't be deceived" (μὴ πλανᾶσθε, mē planasthe) serves as a crucial warning, indicating that some in the Corinthian church might have been taking sin lightly or believing it to be acceptable ^[5]. This deception could stem from a misunderstanding of Christian liberty or a failure to grasp the transformative power of the Holy Spirit ^[5]. The Tyndale House commentary suggests that "continuing to indulge unrepentantly in sexual sin indicates a heart that has not been renewed by the Holy Spirit" ^[5]. This implies that the issue is not merely isolated acts of sin, but a persistent, unrepentant lifestyle that contradicts the faith one professes ^[5].

While "adultery" primarily refers to sexual infidelity, the term can also carry broader metaphorical meanings in biblical literature. For instance, in the book of Hosea, "adulterers" is used to describe spiritual apostasy and disloyalty to God, as well as disloyalty to the king ^[6]. However, in the immediate context of 1 Corinthians 6:9, the literal interpretation of sexual infidelity is clearly intended, given its placement among other explicit sexual sins ^{[1, 2]}.

The list of vices in 1 Corinthians 6:9-10 is not exhaustive but representative of behaviors that are antithetical to God's kingdom. Besides sexual sins, Paul also lists idolaters, thieves, the greedy, drunkards, revilers, and swindlers ^{[1, 4]}. This broad spectrum of unrighteousness highlights that the Kingdom of God is a "kingdom of righteousness" (Romans 14:17) ^[3]. The inclusion of "unrighteous" (ἄδικοι, adikoi) at the beginning of the list serves as an overarching category, encompassing all forms of wrongdoing ^[3]. The Jamieson, Fausset & Brown commentary translates adikoi as "Doers of wrong," linking it to the previous verse where Paul criticizes the Corinthians for wronging and defrauding one another ^[3].

The passage functions as a stark reminder that Christian faith is not merely a set of beliefs but a call to a transformed life. The apostle's concern is that the Corinthians, who had been "washed, sanctified, and justified in the name of the Lord Jesus Christ and by the Spirit of our God" (1 Corinthians 6:11), might revert to their former ways ^[1]. Matthew Henry notes that Paul "takes occasion hence to warn them against many gross sins, to which they had been formerly addicted" ^[7]. This implies that the Corinthian believers had a past characterized by these very sins, and Paul is urging them to live consistently with their new identity in Christ. The warning about not inheriting the Kingdom of God serves as a powerful incentive for believers to live lives that reflect their faith ^[5].

The concept of "inheriting the Kingdom of God" signifies participation in God's redemptive reign and eternal blessings. It is not merely about future salvation but also about present alignment with God's will and character. The passage emphasizes that those who "willingly sin" and "indulge unrepentantly" in these behaviors demonstrate a lack of genuine transformation ^[5]. This does not suggest that a single sin irrevocably bars one from the Kingdom, but rather that a lifestyle characterized by unrepentant sin is incompatible with the nature of God's rule and the work of the Holy Spirit in a believer's life ^[5].

Paul's admonition in 1 Corinthians 6:9-10 is part of a larger theological argument throughout his letters concerning the ethical implications of the gospel. Similar vice lists appear in other Pauline epistles, such as Galatians 5:19-21, which also warns that "those who practice such things will not inherit the kingdom of God." These lists serve to delineate the kind of conduct that is inconsistent with Christian discipleship and the new life in Christ. The passage therefore functions as a foundational text for understanding Christian ethics, particularly regarding sexual morality and the necessity of a transformed life for those who claim to follow Christ.
