Lesson from the first letter of St. Paul the Apostle to the Corinthians1 Cor 6:1-6
1 Dare any of you, having a matter against another, go to be judged before the unjust, and not before the saints
2 Know you not that the saints shall judge this world And if the world shall be judged by you, are you unworthy to judge the smallest matters
3 Know you not that we shall judge angels how much more things of this world
4 If therefore you have judgments of things pertaining to this world, set them to judge, who are the most despised in the church.
5 I speak to your shame. Is it so that there is not among you any one wise man, that is able to judge between his brethren
6 But brother goeth to law with brother, and that before unbelievers.
