(LL: scandalum, stumbling block)

Any word or action which has at least the appearance of evil, and which is the occasion of sin to another. It is a grave sin in grave matter because it is opposed to the law of charity. Christ speaks of scandal: "Woe to the world because of scandals. For it must needs be that scandals come: but nevertheless woe to that man by whom the scandal, cometh." (Matthew 18)
