But brother goes to law with brother, and that before the unbelievers.
All Commentaries on 1 Corinthians 6:6 Go To 1 Corinthians 6
John Chrysostom
AD 407
When brothers go to law against each other, there is no need for a mediator to show understanding and discernment. Brotherly feeling and relationship contribute greatly toward the settlement of such quarrels. To take such a quarrel before unbelievers merely makes everything that much worse and prevents a happy resolution of the problem.
