Excommunication is also for the long-term welfare of the one being disciplined by the church. Paul, in 1 Corinthians 5:5, states that excommunication is a way of delivering the unrepentant sinner “over to Satan, so that the sinful nature may be destroyed and his spirit saved on the day of the Lord.” This means that excommunication can somehow involve God’s using Satan (or one of his demons) as a disciplinary tool to work in the sinner's life physically to bring about true repentance in his/her heart.
Kutengwa pia ni ustawi wa muda mrefu wa mmoja anaye pewa nidhamu na kanisa. Paulo, katika 1 Wakorintho 5:5, anasema kwamba kutengwa ni njia ya kutoa mwenye dhambi asiyetubu "kwa Shetani, ili hali ya dhambi iangamizwe na roho yake iokolewe siku ile ya Bwana." Hii ina maana kwamba kutengwa kunaweza kuwa kwamba kunahusisha Mungu kwa kumtumia Shetani (au mojapo wa mapepo yake) kama chombo cha nidhamu hufanya kazi katika maisha ya mwenye dhambi kimwili huleta toba ya kweli katika / moyo wake.
