1 It is actually reported that there is sexual immorality among you, and such sexual immorality as is not even named among the Gentiles—that a man has his father’s wife! 2 And you are puffed up, and have not rather mourned, that he who has done this deed might be taken away from among you. (1 Corinthians 5:1–2, NKJV)
A Christian was committing fornication (porneia) with his father’s wife, and the Corinthian church was doing nothing to remove the immoral man from their number. Sadly, many churches repeat that pattern. Many churches openly accept the sin of fornication (premarital, extra-marital, heterosexual, and homosexual, 1 Cor. 6:9). Some churches condemn fornication but accept false doctrines that result in having fellowship with adulterers (Matt. 5:32; 19:9; 1 Cor. 7:10-11; Rom. 7:2-3). Some churches ignore the issue. But, the Holy Spirit did not ignore the sexual sin at Corinth. The sin’s unaddressed presence was infecting the church with a prideful and casual approach toward sin that had to cease (1 Cor. 5:2-7). Sexual immorality cannot be swept under the rug and ignored. Paul told the Corinthians to discipline the sinner to motivate his repentance and salvation (1 Cor. 5:3-5; 2 Cor. 2:6-11). Christians do not embrace fornication. It is a work of the flesh that is against God, and those who practice it will not inherit the kingdom of God (Gal. 5:19, 21). We must also reject teachings that enable fornicators to continue their sin (Gal. 1:6-9; 2 Jno. 9-11). We must “come out…and be separate” from those who sanction sin (2 Cor. 6:17). Determine not to rationalize and accommodate sin, for that only leads to eternal death (1 Cor. 5:13).
