           Disfellowshipping is designed to keep the congregations free from the influence of unrepentant wrongdoers who persist in sin as their leaven-like attitude could present an unwholesome atmosphere within the congregations and even cause others to be defiled. Keeping the congregation clean will allow the free flow of Holy Spirit, depriving no one of the undeserved kindness of God. (Hebrews 12:14-17)
