Zwingli: On the Perpetrators of Fraud

If it is found that he [i.e., someone] has gained his ends fraude egisse, i.e., by fraud, one owes him no more than the Romans did Jugurtha, who by means of bribes sought to have the murder of his own brothers entirely disregarded, of which he boasted openly when leaving Rome, saying: “Oh this venal city! A merchant could attain anything he pleased if he only had enough money”; and in fact Jugurtha could have proved the truth of his own words if the upright Metellus Numidicus had not defeated and overthrown him on several occasions and thus seriously injured his cause; for too long a period had Jugurtha bred treachery in Rome by means of his money. And finally he fell into the hands of the Romans. Thus, in accordance with the proverb, “deceit turns upon its own creator,” and it is well thus when someone attempts to commit treachery and does something behind the back of upright people. — Huldrych Zwingli
