[Church] discipline has three primary purposes. The first is to restore fallen Christians to usefulness to God and fellowship with His church (see Matt. 18:12-14; 2 Cor. 2:5-11; 7:8-10; Gal. 6:1-2; Jas. 5:19-20). The second is to guard and preserve the honor of God (see Rom. 2:24; 1 Cor. 10:31). And the third purpose is to protect the purity of the church (see Rom. 16:17; 1 Cor. 5:6; 1 Tim. 5:19-20) (Wayne Grudem and Dennis Rainey).
