1 Corinthians 5 addresses a specific case of sexual immorality within the Corinthian church, where a man is involved with his father's wife. The author expresses shock and disapproval at the congregation's boasting rather than mourning the situation. The passage instructs the church to expel the individual to hand him over to Satan for the destruction of his flesh, hoping for the salvation of his spirit. Furthermore, it clarifies that believers should avoid associating with those claiming to be believers but engaging in serious sin, unlike those outside the church whom God will judge. The text also uses the metaphor of yeast to illustrate how sin can corrupt the whole group.
