Chapter 41: Lord's Day 41
Section 111. Q. 111: But what does God require of you in this commandment? A. That I do whatever I can for my neighbor's good, that I treat others as I would like them to treat me, and that I work faithfully so that I may share with those in need.
Section 112. Q. 112: What is the aim of the ninth commandment? A. That I never give false testimony against anyone, twist no one's words, not gossip or slander, nor join in condemning anyone without a hearing or without a just cause. Rather, in court and everywhere else, I should avoid lying and deceit of every kind; these are devices the devil himself uses, and they would call down on me God's intense anger. I should love the truth, speak it candidly, and openly acknowledge it. And I should do what I can to guard and advance my neighbor's good name.
