Chapter 31 — Part III: The Decalogue — The Eighth Commandment
Section 35. All Must Speak Truthfully And With Charity — To all conscientious persons is addressed the divine command that in all their intercourse with society, in every conversation, they should speak the truth at all times from the sincerity of their hearts; that they should utter nothing injurious to the reputation of another, not even of those by whom they know they have been injured and persecuted. For they should always remember that between them and others there exists such a close social bond that they are all members of the same body.
