Jesus and Paul both urge us to discern when someone's teaching or behavior is ungodly (Mt. 7:15-20; 2 Tim. 2:23-4:5). We may even rebuke a sinner gently, if necessary (Lk. 17:3-4, Gal. 6:1), with a loving eye to repentance, but all feelings of scorn, superiority, condescension, or self-righteousness are to be confessed as sin before we confront the person (Mt. 7:1-5).
