DISCIPLINE may become necessary to maintain purity and holiness in the Church and to encourage repentance in those who have not responded to the admonition of brothers and sisters in Christ, and of the Church, to forsake their sins. Church discipline often centers around exclusion from receiving Communion (excommunication). The New Testament records how Saint Paul ordered the discipline of excommunication for an unrepentant man involved in sexual relations with his father's wife (1 Corinthians 5:1-5). The Apostle John warned that we are not to receive into our homes those who willfully reject the truth of Christ (2 John 9, 10). Throughout her history, the Orthodox Church has exercised discipline with compassion when it is needed, always to help bring a needed change of heart and to aid God's people to live pure and holy lives, never as a punishment.
