It must be a decisive rule of all Christian community life that each individual is prohibited from talking about another Christian in secret.
Let no evil talk come out of your mouths, but only what is useful for building up, as there is need, so that your words may give grace to those who hear. Ephesians 4:29
Set guard over my mouth, O Lord; keep watch over the door of my lips. Do not turn my heart to any evil, to busy myself with wicked deeds in company with those who work iniquity. Psalm 141:3-4
