The analysis of a controversial formula of exclusion from the community of believers found in 1 Cor 5,5 leads us to the primary conclusion that the recommendation we find here can be treated as a rule of how a community should act in such a situation. Paul alludes to the real case of the Church member in Corinth having incestuous relationship . Such behavior is judged as harmful not only to those who are engaged in it but it also has a social dimension as it does wrong to the whole community of believers, which ceases to be credible. Consequently, the community that is untrustworthy is unable to give true witness to Jesus Christ. The rhetorical perspective prompts us to broaden the above recommendation to all the instances of overt evil within the community. The moral assessment of the act is evident. What Paul is trying to correct is the lack of the community reaction to evil that spreads in it. The Apostle urges the community to formally exclude the sinner. It is to be seen as a firm objection against evil and is motivated by the care for the spiritual wellbeing of both the wrongdoer and the community itself. The community should hope that the sinner will change his attitude and thus will obtain salvation when the day of the Lord comes.
